Phase-II Of The Grid Connected Rooftop Solar Programme

In grid connected rooftop or small solar photovoltaic (SPV) system, the DC power generated from solar panel is converted to AC power using power conditioning unit/Inverter and is fed to the grid

A 1 kW rooftop system generally requires 10 sq. metres of shadow-free area. However, actual area requirement may vary depending on the efficiency of solar | module, and their placement etc.

Saving on electricity bill by the consumer. | Utilization of available vacant roof space, no additional land required. | Low gestation period. | No additional requirement of transmission and distribution (T&D) lines. | Reduces T&D losses as power consumption and generation are collocated. | Improvement in the tail-end grid voltages and reduction of system congestion. | Long term energy and ecological security by reduction in carbon emission. | Better management of daytime peak loads by DISCOM/ utility. | - Meeting of the Renewable Purchase Obligations (RPOs) of obligated entities.

The current benchmark cost of grid-connected rooftop solar systems can be seen in the notification section at https://solarrooftop.gov.in/notifications/view

Central financial assistance (or subsidy) is available only for residential sector grid-connected solar rooftop projects only. For other sectors e.g. Govt., institutional, social, commercial, industrial etc. CFA is not available. | Central Financial Assistance (CFA) to Residential sector | CFA @ 40% of benchmark cost or @40 % of tendered rates (whichever is lower) | for capacity up to 3 kWp | CFA @ 20% of benchmark cost or 20 % of tendered rates (whichever is lower) for | capacity beyond 3 kWp and up to 10 kWp | CFA @ 20% of benchmark cost or @ 20 of tendered rates (whichever is lower) for | GHS/RWA capacity up to 500 kWp (limited to 10 kWp per house and total upto | 500 kWp) | For calculation of CFA, the PV plant capacity will be inverter capacity or the PV module capacity, whichever is lower. For availing CFA, the PV module and cell shall be manufactured in India only.

No. Consumer has to pay the balance amount after deducting the subsidy (eligible CFA) from the L1 project cost discovered by the DISCOMs. Advisory on scheme is also available at https://mnre.gov.in/img/documents/uploads/file_f1610949591054.pdf

Residential consumers and Group Housing Society can apply for installation of solar rooftop system through the online portal of DISCOMs. The link for the online portal of DISCOMs is mentioned- https://solarrooftop.gov.in/grid_others/discomPortalLink

The interested beneficiary may install the solar rooftop systems through project developers/system integrators/manufactures etc. after taking necessary approval from DISCOMs within the capacity limit as laid down in the order of respective State Electricity Regulatory Commission/Joint Electricity Regulatory Commission of the respective States/UTs.

The RTS under any framework like net or gross metering can be installed by the electricity consumer. So, if you have electricity connection in your name and you pay regularly the electricity bill in your own name and also you have the permission of use the roof for solar rooftop installation from the owner, you can install the RTS.

Solar PV modules used in solar power plants /systems must be warranted for their output peak watt capacity, which should not be less than 90% at the end of 12 years and 80% at the end of 25 years. The mechanical structures, electrical works including power conditioners/inverters/charge controllers/maximum power point tracker units/distribution boards/digital meters/switch gear/storage batteries, etc. and overall workmanship of the SPV power plants/ systems must be warranted against any manufacturing/ design/ installation defects for a minimum period of 5 years.

Government of India has set the target of installing 40,000 MW of Rooftop Solar (RTS) Power by the year 2022. State-wise tentative targets are available in the website link (State-wise-and-year-wise-target-for-installation-of-40000MWp-GCRTsystems_0.pdf) )
