MNRE provides Central finance assistance (CFA) of 30 per cent of the benchmark cost for grid-connected rooftop projects. (The benchmark cost for 2019-20 for systems up to 10 kWp is INR 54,000 per kW; for >10–100 kWp it is INR 48,000 per kW; and for >100–500 kWp is 45,000 per Read more…
The limit on the capacity of an individual solar rooftop system variesacross states. A consumer in Delhi can install a system of a capacitymatching his sanctioned load; in Madhya Pradesh, the maximum capacityof the system can only be 50 percent of the load.
1- Grid-connected solar rooftop PV systemA grid-connected solar rooftop PV system is, as the name suggests, a plant connected to the grid through net or gross metering without any battery backup. Most of the state governments and the Central government are promoting this type of rooftop system. 2- Hybrid plantA Read more…
In 2016, Government of India released model building bye-laws and issued an amendment in the Environment Impact Assessment (EIA) Notification, 2006 in order to promote and encourage solar rooftop systems in the building sector.The EIA Notification (which states are required to integrate with their building bye-laws) mandates all buildings spread Read more…
Under the CAPEX model (pursued by developers like Sukam, Moserbaer and Tata Power Solar), a consumer purchases a solar rooftop plant like any other electronic gadget by investing in the entire system. The drawback of the model is that rooftop owners have to pay for the entire project at the Read more…
Under this model, a third party—a solar power developer installs the plant on the rooftop and sells the generated power to the consumer. The consumer does not have to make any investment.
