Bangalore is the third most populous city in the country. Electricity distribution to it is taken care of BESCOM (Bangalore Electricity Supply Company Ltd.) In the recent years, it has revised and increased the tariffs for electricity consumption. This has made solar rooftop system Bangalore a more feasible and economic option for all Bangaloreans to adopt.

Rooftop space required for installing a solar rooftop system

 

Statistics says that the average monthly electricityconsumption in the city is approximately 90 units per capita. If a household of 3 to 4 persons uses 9 – 12 units per day, it will be 270 – 360 units per month. The per unit cost will be some Rs.7 per unit. This electricity need (12 units per day) can be met by a rooftop solar system of 3kWp capacity. For installing this, approximately 300 sqft of usable space (shade-free, easily accessible space) on your rooftop.

 

An agreement with BESCOM for installing solar rooftop system at your household

 

An agreement known as power purchase agreement (PPA) has to be signed by the homeowner with BESCOM under the current net-metering policy to get the solar rooftop system up and running. BESCOM will check that your project proposal adheres to certain guidelines, and approve it. Once the installation is done, a bi-directional meter will replace the home’s current electricity meter. This meter is capable of tracking power drawn from the grid by the household and the power sent back to the grid from the solar rooftop system.

 

Your electricity bill will be based on the net import/export from the grid

 

Once the system is running, the net import/export from the grid will be shown by the electricity bills received by the household on a monthly basis. If the household has consumed power from the grid, there will be net import, and the consumer will be billed as usual. If the household’s solar rooftop system has generated more power than used by the household, there will be net export, and BESCOM will pay the consumer for it within the next 30 days via bank transfer. This amount will be as indicated in the PPA.

 

Tariff for solar projects

 

Presently, there is a significantly higher tariff (Rs.9.56 per unit) for solar projects installed without government subsidies (for government-subsidized projects, the rate is Rs.7.20 per unit). Bangaloreans can submit online applications for installing rooftop solar systems to the BESCOM. BESCOM’s website offers complete guidelines and application forms for the same.

 

Government subsidies for installing solar rooftop system Bangalore

 

The price of a 3kWp solar rooftop system is presently some Rs.2.9 lakhs. By getting government subsidies, this cost can be lowered. However, the subsidies given by the Government of India MNRE for this purpose are hard to receive because of a priority list for approval. So, MNRE suggests that you go for solar rooftop projects without anticipating subsidies.
