Why Solar in India?
India receives 300+ sunny days per year with 4-7 kWh/sq.m/day solar irradiance. Making it one of the best countries for solar energy. With electricity rates rising 5-8% annually and PM Surya Ghar offering up to Rs 78,000 subsidy for rooftop solar, there has never been a better time to go solar.
A typical 3kW rooftop solar system generates 12-15 units of electricity daily, covering most of a 2-3BHK household's needs. After the government subsidy, the net investment is Rs 80,000-1,20,000. paid back in 3-4 years through electricity savings of Rs 25,000-35,000/year.
Solar Electrical Products You Need
