FAQs on Grid Connected Solar Rooftop System:


1.  What is Grid Connected Solar Rooftop System?

Ans: Unused open space on the roof (shadow free)can be utilised to install solar panel for generation of DC electric energy. This DC energy is converted into AC energy using inverter and the AC power output is connected/integrated to the grid (distribution power lines). This system is called Grid connected solar rooftop system. The programme encourages installation of rooftop solar photovoltaic power generation plant for self-consumption as well as sale of electricity generated from the solar to the grid.

2. How solar rooftop system can be connected to the grid (distribution power lines)?

Ans: The connection of rooftop system to the grid can be carried out through two mechanisms, viz Net Metering and Gross Metering.

Net metering: In Net metering, the power output from solar panel supplies electric energy to consumer premises and the surplus energy, if any, is fed to the grid. In times of deficit of electricity from solar generation, electric energy will be drawn from the grid.

Gross Metering: In case of Gross metering, all the electric energy generated from solar panel is fed to the grid while energy requirement of the consumer is drawn from the grid lines.

The type of metering to be incorporated with the Solar Rooftop system will be left to the consumer’s discretion.

3. What are the facilities/incentives provided for Grid connected solar rooftop system?

Ans: The Ministry of New and Renewable Energy (MNRE) Govt. of India is providing Central Financial Assistance (CFA) upto 70% of benchmark cost for all types of residential buildings for North Eastern States. Similar CFA is also available for schools, health institutions including medical colleges & hospitals, universities, educational institutions and other Social Sectors such as welfare homes, NGOs, training institutes, orphanages etc. that come under non-profit making body.

No CFA is applicable for Government/PSU buildings, Government Institutions, Private/Commercial/Industrial buildings.

The benchmark cost of MNRE is Rs 75,000/- per KW and 70% of benchmark cost i.e. Rs 52,500/-  is applicable as Central Finance Assistance.
