Recent newspaper articles have highlighted the rooftop photovoltaic (RTPV) sector’s sluggish growth in India. The articles claim that based on the present outlook, the 40 GW target for 2021-22 will not be achieved.
Greenpeace India’s report shows that RTPV uptake in major cities such as Delhi, Mumbai, Bengaluru, Hyderabad and Chennai has been abysmal. While the large-scale ground mounted solar parks have gathered critical mass in India with tariffs as low as Rs 2.44/kWh, RTPV is lagging behind significantly, comprising only about 1.46 GW of today’s 12.5 GW installed solar capacity.
Statements from officials insinuating that Indians want to use their rooftops for alternative purposes such as drying clothes, sleeping and hosting parties are extremely misleading. RTPV systems can easily be designed with raised mounting structures, at low incremental costs, to keep enough free space and provide a cooling effect below.
A deeper look into the problem reveals the major barriers hindering growth of RTPV in India.
A typical kW level system costs Rs. 60,000-75,000/kWp which is 1.5-2 times more than ground-mounted behemoths. For a lucrative business case for prospective consumers, with a healthy internal rate of return (IRR>13 per cent) and payback period (
