Though the whole of solar power was seen as a game changer early on, the electricity distribution companies (discoms) managed to put out hurdles in the form of restrictions to open access, land acquisition, cross subsidies on tariff and dragging their feet on the regulatory measures. Given the situation, the one segment that has emerged as a possible disruptor is the humble rooftop. Currently at 900 MW (despite the limited availability of net metering), rooftop solar does not have the glamour of 10,000 acres of solar park with who’s-who of the industry clamouring for space. Very simplistically put, it can be installed anywhere where there is a flat rooftop and few hours of sunshine.
