The Company

PUK-Werke KG Berlin is an independent private enterprise run in the best tradition of German medium-sized businesses and can look back on 75 years of successful company history Over the past decades PUK has gathered experience in the development production and assembly of cable support systems and underfloor systems for German and international construction projects Throughout our history we have been constantly working on enhancing and expanding our product portfolio

PUK has enjoyed equal success with its newest product group an underframe mounting system for photovoltaic panels called PUK-Solarline After an intensive development phase the system was ready for market at the end of 2009 and has since been installed in many PV plants in Germany and Europe

PUK-Solarline is a statically optimised and tested mounting system that is simply designed good value and easy to install The system including all the fittings is manufactured exclusively by PUK in Germany and can be used for all types of solar modules

A decisive advantage of PUK-Solarline is our ability to take care of all project responsibilities from planning to completion PUKrsquos wide range of services includes foundation work delivery base frame construction and mounting of the solar modules

The requirements of every PV installation are taken into account and an individual offer is prepared First all relevant project details are recorded in a construction planning data sheet Based on this information the

dimensioning programme PUK-SolarWare can determine the optimal base frame configuration for every PV installation

PUK-SolarWare structurally analyses the project requirements and then based on British Standards DIN 1055 and Eurocode regulations verifies the optimal mounting structure

All parts are manufactured in our own production facilities either in Berlin or in our Schoumlnecken factory in Rhineland-Palatinate The supporting profiles cross beams longitudinal beams diagonal strutting and connector parts are all made of steel The next step is hot-dip galvanizing which ensures a minimum durability of 25 years

Ground Mounted InstallationsStructual Systems Analysis

PUK-Software

PUK-SolarWare SW 108 dimensioning software enables us to design the most suitable base construction for every PV system Only four steps are necessary to determine the minimum amount of material and erection work required

This software establishes each PV systemrsquos individualised structural configuration based on our own wind-load tests as well as on DIN 1055 the Euro codes and DIN 18800 As PUK-SolarWare has incorporated wind- and snow-load data for all European countries its structural analysis is accurate for construction projects throughout the EU

Our dimensioning software verifies the optimal components and support configuration needed to fulfil the systemrsquos load-bearing requirements

PUK-SolarWare gives the project manager the security of using a statically tested and economically optimised mounting system

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsStructual Systems Analysis

PUK-Software

PUK-SolarWare SW 108 dimensioning software enables us to design the most suitable base construction for every PV system Only four steps are necessary to determine the minimum amount of material and erection work required

This software establishes each PV systemrsquos individualised structural configuration based on our own wind-load tests as well as on DIN 1055 the Euro codes and DIN 18800 As PUK-SolarWare has incorporated wind- and snow-load data for all European countries its structural analysis is accurate for construction projects throughout the EU

Our dimensioning software verifies the optimal components and support configuration needed to fulfil the systemrsquos load-bearing requirements

PUK-SolarWare gives the project manager the security of using a statically tested and economically optimised mounting system

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Potential Equalisation

The potential equalisation of the longitudinal beams and connectors is calculated and provided for each installation

Lightning Protection

Ground mounted PV installations are secured by lightning protection systems

Building Site

The foundation can be prepared by pile driving the supporting structure using ground anchors or laying concrete foundations Geological surveys as well as pile driving and extraction tests are necessary to determine the type of foundation and ramming depth

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsAssembly

1 Pile driving the supporting rods

Hydraulic pile drivers insert the profiles into the ground Depending on the soil the profiles are driven approximately 15 to 20 metres into the ground

3 Mounting the longitudinal beams

The longitudinal beams fulfil the constructionrsquos stability requirements as determined by our earlier static calculations The longitudinal beams are connected to the cross beams with special brackets

2 Assembly of the diagonal and cross beams

During assembly the cross beams are bolted into the profilesrsquo slotted holes thus securing the required module inclination The supporting frame is reinforced with diagonal beams

4 Mounting the modules

The solar modules are mounted directly onto the longitudinal beams with safety-certified module clamps The anchorage points on the longitudinal beams are pre-punched according to the width of the module

Examples of foundation work installation and module mounting

Detailed assembly instructions are naturally included with all projects

29

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsPile Driving

PUKrsquos own hydraulic pile driver rams the supporting profiles into the ground with millimetre precision thus securing the base structure

The pile-driving depth is generally between 15 and 20 metres To determine the exact depth we perform pile driving and extraction tests The tensile forces measured in these tests are then compared to the statically dimensioned load values and any discrepancies are accounted for

A geological survey is helpful for determining the pile-driving depth but not absolutely necessary

Soil class 3 to 4 is suitable for pile driving Small stones or minor building debris with a particle size of less than 60 mm will not impede pile driving

If the ground is not firm enough and the extraction values are too low the values can be increased threefold by slanted pile driving and by attaching profiles at an oblique angle to the back support profile Structural safety is thus easily and economically ensured

30

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsConcrete Anchoring

If the stones are too large or the ground too rocky drilling becomes necessary

On smooth high-quality concrete surfaces the supporting profiles are secured with anchor bolts

After the hole is drilled the pile is set in concrete

If the concrete is of poor quality the surface is cracked andor porous or the concrete is less than 30 cm a hole is bored into the ground with heavy construction equipment The support is then driven through the hole into the earth below

If ground penetration is not possible (because of landfills or other obstacles such as concrete blocks bricks etc) PUK-Solar can provide concrete foundation elements First the supports are provisionally secured in the ground inside individually designed moulds

Then concrete is poured into the mould and the columns are precisely aligned After the element is partially cured the assembly can continue

After the concrete is completely cured the mould is easily removed and can be used for other concrete elements

31

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1

Ground Mounted InstallationsTechnical data

Corrosion Protection

Because solar support systems are exclusively used outside PUK-Werke KG uses only hot-dip galvanised steel parts (dipping method DIN EN ISO 1461)

Hot-dip Galvanising Method (DIN EN ISO 1461)

According to DIN EN ISO 1461 the galvanised layerrsquos average thickness must be at least 45 μm for material less than 15 mm thick 55 μm for material between 15 and 30 mm thick 70 μm for material between 35 and 60 mm thick

The mounting hardware can be produced of high-grade stainless steel or aluminium as appropriate

Contact Corrosion

Insulation measures are only required if the parts in contact are approximately the same size

Therefore the following combinations are acceptable- stainless steel fastening fixtures (eg screws)

galvanised construction parts- stainless steel fastening fixtures aluminium module

clamps- galvanised construction components (ie the support

system) aluminium module clamps

Problematic component combinations will be examined by our engineers and noted on the final assembly drawings

Bolted Connections

Outdoor bolted and screwed connections are subject to dynamic stress (eg wind)

Therefore the connections must be tightened as described in Table 1
