The Haryana government is targeting 4,200 megawatt of solar power by 2022, including 1,600 mw from roof top solar power plants. Surplus power generated through installation of rooftop solar panels by any type of building, if any, could be fed into the state grid under net-metering regulations, Ankur Gupta, principal secretary, renewable energy, said on Monday.
He said the cost of solar power is declining, making it a viable option for not only industrial and commercial buildings but also for individual households. A typical 1 kw solar power plant costs about Rs 70,000 to 75,000 and produces about 1,500 units of electricity annually. That means the payback period is just about four years whereas life of the system is more than 25 years, Gupta said.
To encourage installation of grid connected rooftop solar power plants, the government is providing financial incentive of Rs 20,000 per KWp, or 30 per cent of the benchmark cost of the plant, whichever is less, to all categories of users except the commercial and industrial establishment of private sector, Gupta said.
