Rooftop Solar is MUST to meet the target of 100 GW.

The country has set an ambitious target of installing 175 GW of renewable energy capacity by the year 2022, which includes 100 GW from solar, 60 GW from wind, 10 GW from bio-power and 5 GW from small hydro-power.

Out of 100 GW solar capacity target, 40 GW is likely to be achieved by installation of rooftop solar projects. Rooftop solar is the fastest growing renewable energy sub-sector in India but installations must rapidly accelerate if the nation is to meet its ambitious renewable energy target by 2022. India has installed 28 GW of solar capacity, a four-fold increase in less than three years. Despite this strong growth, India has achieved only 10 per cent of its 40 GW rooftop solar target. This is well below the run-rate anticipated by government. To achieve the 2022 target, India will have to greatly accelerate the pace of new solar rooftop installations. See more
