Before & After InstallationBefore InstallationPlease carefully read this manual beforeinstallation.• Solar module installation should be performed by

an authorized installer for the safety andmaintenance of the system.

• All installation instructions should be clearlyunderstood before attempting installation.

• Do not twist, pull, or scratch the cable attached tothe solar module.

• Do not touch the solar module with bare hands. Itmay result in a burn or injury.

• Do not drop the solar module and cause anexcessive load on solar module.

• Do not disassemble the solar module.• After installation or repair, check whether solar

module operates properly or not.• In case the currently used solar module or the

parts applied to the solar module have beenreplaced, check whether the changed solarmodule is properly operated or not. The newlyreplaced solar module and its parts must be thesame solar module(module name) and parts withthe current solar module.

• Please contact the local office to confirm theregulations and to obtain permission.

• Do not let anyone approach the solar modulewho has little knowledge of solar modules or onthe measures to take when solar modules aredamaged in order to avoid the risk of injury orelectrical shock.

• Do not locate the solar module horizontally, asthis may cause dirt or white efflorescence (glassdeformation)

• Panels produce voltage even when notconnected to an electrical circuit or load.

• Panels are intended for outdoors, land basedapplications only. Panels are not intended for useindoor use or application on moving vehicles ofany kind.

• Reflection from external environments such assnow, water or other surfaces can increase thepower generated by the panel.

• Industry standard rated specifications are madeat conditions of 1000W/m2 irradiance and 25°C(77ºF) solar cell temperature. Colder temperatur-es can substantially increase voltage and power.

• Keep the solar module and system away fromchildren when installing.

• Keep the module packed in the carton until thetime of installation.

• Make sure flammable gases are not generatednear the installation site.

• Do not work alone. Please work as part of a teamof two or more people.

• Wear a safety belt if working high above theground.

• Contact with electrically active parts of the panels,such as terminals, can result in burns, sparks andlethal shock whether the panel is connected ordisconnected.

• Even partial shadowing can substantially reducepanel and system output.

• Care must be taken to avoid low tilt angles whichmay cause dirt to buildup on the glass against theframe edge.

• Dirt build-up on the surface of the panel cancause active solar cells to be shaded andelectrical performance to be impaired.

• Always keep the back surface of the panel freefrom any foreign objects or structural elementswhich could come into contact with the panel,especially when the panel is under mechanicalload.

• For permission to use mounting methods notdescribed in the Mounting Guide please consultLG Solar. Failure to do so will void the warrantyand panel certification.

After Installation• Plug the connector in tightly and ensure that the

wiring properly works.• It is advisable to conduct periodic inspection of

the panels for damage to front glass, back sheet,frame, junction box, or external electricalconnections.

• Check electrical connections for loose connec-tions and corrosion.

• PV panels can operate effectively without everbeing washed, although removal of dirt from thefront glass can increase output.

• Water, ethanol or a conventional glass cleanserwith a micro-fiber cloth can be used for regularwashing or rinsing of the front glass to removedust, dirt or other deposits.

• No aggressive and abrasive cleansers orchemicals such as alkali chemicals includingammonia based solution should ever be used onthe treated front glass.

• Always wear rubber gloves for electricalinsulation while maintaining, washing or cleaningpanels.

• Deposits of foreign material on the frame surfacecan be cleaned using a wet sponge or cloth anddried in air or by using a clean chamois.

• Perform the wiring work by connecting theconnector and wires to the stand away from theroof or ground.

Electrical Installation

Caution• Avoid all electrical hazards when installing, wiring,

operating and maintaining a panel.• Do not use panels of different electrical or

physical configurations in the same system.• Match the polarities of cables and terminals when

making the connections; failure to do so mayresult in damage to the panel.

• When reverse currents can exceed the valuemarked on the name plate, a properly rated andcertified over-current device (fuse or circuitbreaker) must be connected in series with eachpanel or string of panels.

• The rating of the over-current device shall notexceed the maximum series fuse rating markedon the name plate.

• The panel contains factory installed bypassdiodes located inside the junction box.

• When installing the system, it is recommended toinstall the lightning rod to protect the system.

• The junction box should not be opened. Openingthe junction box may void the warranty.

• Panels with a suspected electrical problemshould be returned to LG Electronics forinspection and possible repair or replacement asper the warranty conditions provided by LGElectronics.

Electrical Connections• Modules may be connected in series and/or

parallel to achieve the desired electrical output aslong as certain requirements are met.

• Please use only the same type of modules in acombined source circuit.

• Do not disconnect the module under load.Shock hazard can occur near the solar modules

connection means.

Series Connection• The solar modules may be wired in series to

produce the desired voltage output.• The current of each module connected in series

should be same.• The maximum number of series connected

modules can be determined by basis on max.system voltage, the 125% safety factor, and themodule Voc which can be checked in “ProductSpecifications” in this document.

• Do not exceed 80% of maximum system voltage.• The maximum solar module configuration can be

found in “Product Specifications”.

Series connection for more voltage

Parallel Connection•The solar modules may be combined in parallel toproduce the desired current output.• When modules are combined in parallel, the totalcurrent is equal to the sum of currents from eachmodule.•The voltage of each module connected in parallelshould be same.•When connecting plural strings of modules inparallel every series string or solar module must befused prior to combining with other strings.

By pass diodes are factory installed in the solarmodules.•Please refer to the applicable regional and localcodes for additional fusing requirements andlimitations on the maximum number of solarmodules in parallel.•Maximum parallel strings without propermeasures, e.g. fuse 15A and/or blocking diode :1 stringParallel configuration is not limited if proper

measures are taken to block the reverse currentflow, e.g. fuses for the protection of the moduleand cables from over-current and/or blockingdiodes for prevention of unbalanced string voltage.• A multiplying factor is required for increasedoutput of the PV modules. Under normal conditions,a PV module is likely to experience conditions thatproduce more current and/or voltage than reportedat standard test conditions. Accordingly, the valuesof Isc and Voc marked on this PV module shouldbe multiplied by a factor of 125% whendetermining component voltage ratings, conductorampacities, fuse sizes, and size of controls to thePV output.•Depending on national directives additional safetyfactors might be applicable for overcurrentprotection.
