Rooftop solar must accelerate
India has pledged to have 100 GW of grid-connected solar power capacity by December 31, 2022. Out of this, 60 GW is to come from ground-mounted solar plants while 40 GW is envisaged to come from rooftop solar (RTS). According to reliable estimates, India’s total solar capacity stood at 33.8 GW as of September 30, 2019. The worrisome issue is that the performance of RTS is belying even the most conservative expectations. The total quantum of RTS installations is today barely 4 GW, which is just about 10 per cent of the 2022-target.
