Coating India's Rooftops with Solar Photovoltaics

摘要

It is a known fact that India is a rarest of the countries rich with sunlight radiation and offers the best hope to revolutionise solar energy in the world. It receives about 5,000 trillion kWh of radiation annually. For every square kilometre 50 MW of solar power can be commissioned that can yield average annually 42.5 GWh of electricity assuming present PV cell efficiency of 15%.
