Rooftop Solar Cost Down by 50 Per Cent in Last 7-8 years: MNRE

Overall cost of the rooftop solar system has come down by 50 per cent during the last seven-eight years, making it more competitive, Parliament was informed on Tuesday.

“The cost of the rooftop solar systems in the country has become competitive with the reduction of cost of Solar PV panels and the overall cost of these systems has reduced by around 50 per cent during the last 7-8 years,” New & Renewable Energy Minister R K Singh said in a written reply to the Rajya Sabha.

Singh also told the House that to promote and make the rooftop solar (RTS) systems affordable in the country, the government has taken various initiatives that include launch of ‘Grid Connected Rooftop and Small Solar Power Plants Programme’ in December 2015 targeting 2100 MW RTS capacity addition by 2019-20 through Central Financial Assistance (CFA).
