In Delhi it is now possible for Cooperative group housing societies (CGHS)  to instal rooftop solar power panels on their buildings. The power department of Delhi government has begun inviting applications from housing societies and individual house owners and also has started the registration process.

“So far, a few housing societies from… Dwarka have expressed interest. We are trying to reach out to societies across the city. Our team will visit these societies soon for inspection. We can then give details, such as area suitable for solar panels, investment needed, cost benefits, and other issues,” said AK Jha, executive officer with the power department.

For the housing societies, there are three categories of solar plants — 1-5 kW, 5-10 kW and above 10 kW, depending on area of the rooftop. According to Jha, the first category will require a rooftop area of 10 sq m.

“If a housing society instals a solar system of 30 kW, which costs Rs 16.5 lakh, they will get a subsidy of Rs 4.95 lakh. A solar plant of this capacity would need a shadow-free area of 312 sq m,” Jha explained.

He continued, “The 100-kW project will cost around Rs 55-60 lakh, of which 30 per cent will be paid as subsidy. Vendors who’ll install the solar panels will also be responsible for maintenance for a period of five years. After that, the vendor will charge for maintenance.”
