Grid Connected Roof Top Solar Power Plant

Solar Photovoltaic

• PV system, is a power system designed to supply usable solar power by means of photovoltaic's. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting ,cabling and other electrical accessories to set up a working system.

Net Meter• Net metering is a billing mechanism that credits

solar energy system owners for the electricity they add to the grid. For example, if a residential customer has a PV system on the home's rooftop, it may generate more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run backwards to provide a credit against what electricity is consumed at night

What is Net Metering

Net metering is the process through which you attain a “dual-benefit “by installing a solar power plant on the roof, open space, walls of the building to generate electricity.

Generated power is first used in the building as per the requirement and the surplus power is fed to the grid of utility.

WHO CAN INSTALL

• Consumers of electricity having minimum sanctioned load of 1.25KW and maximum of 12.50 MW who intend to generate their own electricity and desire to contribute towards environmental protection can install Solar PV plants on Roof-Tops/ Walls/Open area of Individual households, Industries, commercial establishments, institutions, residential complexes, Schools, Colleges, Hospitals, sheds, cold stores, govt. and semi-govt. buildings, etc.

The maximum capacity of solar power plant to be installed in a building would be 80% of the sanctioned electricity load of that building.

What is the Procedure for Net Metering1.Submission of Application

• For installation of solar power plant the applicant has to register/apply online at any one the sites with copy of latest electricity bill and available shadow free area at the top of roof/ walls/ open space within the compound.

Period of Time ::3 weeks

Approval For Installation

• After verification, Discom will give online approval to the applicant for installation of required capacity Solar Power Plant.

• Period of Time: 30 days

Processing Fee & Signing of Agreement with Discom

• The consumer intending to setup Roof Top solar power plant shall deposit  the processing fee of Rs. 50 per KVA or part there of subject to maximum of Rs.10000 in the concerned DS/ Sub Division office of Discom on first come first serve basis. The consumer shall also sign supplementary agreement with Discom 

Installation of Solar Power Plant

• After approval from Discom, applicant will contact Medors to install solar power plant and submit online work completion report along with photograph of the system and single line diagram of the synchronizing and protection arrangements.

Installation of Bi-directional Meter

• After receiving project completion report, Bi-directional meter would be installed at the premises of the beneficiary by Discom. For this, applicant has to deposit prescribed fee of Bi-Directional meter at Sub Divisional Office  of Discom.

Release of  Subsidy

• After installation of Bi-directional meter the plant shall be treated as commissioned and the beneficiary will apply online for release of subsidy to SNA along with the work completion report duly verified by Discom

• Subject to availability of MNRE,GOI funds at the rate of INR 12 Per Watt .

Banking Mechanism And Billing

• Discom shall take energy meter readings for import or drawl and export or injection of power and work out the net energy flow quantum from or to the consumer. In case the net flow is towards the Discom i.e. the consumer has injected/exported the net surplus energy to the Discom system, such quantum will be treated as energy banked by the consumer with Discom in the current billing cycle

Discom Tariff

• The Energy Bill for import will be prepared as per the retail supply tariff as approved by the CERC for the category to which the consumer belongs. The energy exported to Discom from the rooftop Solar PV system shall be set-off against the energy imported from the Discom grid at the CERC approved retail supply tariff applicable to the particular consumer category.

Case Study On Solar Power Plant 10 kw

Scope Of Work

• 10000 wp Solar P.V Plant • European On Line Inverter 10 kW• Galvanized Mounting Structure • Application & Agreement• Approval for Net Metering • Installation & Commissioning

Power Production Per day • 10000 wp solar P.V array • 250 wp x 40 panel = 10000 wp • Module type Crystalline • Hourly out put : 10000 wp at 1000 w/h/mt2 sun

radiance • Perfect Sun hours average 4.5 hrs per day • Per day power output will be 4.5 x 10 = 45 kWh• Yearly production will be 45x 365 = 16425 kWh

Yearly Gross Saving Comparison From Grid

• The Cost of one kWh will be Inr 8 inclusive of taxes so daily saving will be Inr 360/-

• Yearly Saving will be : 16425 kWh x 8 = 1,31,400/-

Pay back period in comparison with grid

• The Cost of the System :- 7,50,000 /-• Subsidy Amount : 1,20,000/-• Saving with Grid :- 1,31,400/- Per Year

• Pay back period with grid is = 4 years

Green Calculation with Grid

• For Producing 1 Unit of Electricity their is emission of 0.6 kg of Co2in atmosphere.

• You Contribute to reduce Co2 from atmosphere by

16425x.06 = 9855 kg per year 9855 kg

Financial Benefits for Installing Solar Roof Top Model

• Accelerated Depreciation in Income Tax• Subsidy form Government Rs. 12 Per Watt • Power Sell Agreement with your Discom• Pay Back Period is 3.5 Years• Life of System is 25 yrs • A Gift to Nation

Individual Benefits :-

Consumer becomes generator for his own electricity requirements.

Reduction in electricity Bills.Elimination of minimum monthly charges.Generation during the day time when

demand is high.
