"On 10th of March this year the installed solar power capacity in India has crossed 10,000 MW, four times the installed capacity three years back, which in next 15 months would cross 20,000 MW," a Power Ministry statement quoted the minister as saying.
"India could not have completely focused on 'Making in India' in the last three years as being in the nascent stage, its solar power sector needed technological and financial boost from abroad to rapidly expand its horizons," Goyal said at a media event.
India solar power generation capacity stood at 2,650 MW on May 26, 2014.
As much as 14,000 MW (or 14 gigawatt) of solar projects are currently under development and about 6 GW is to be auctioned soon.

In 2016, about 4 GW of solar capacity was added, the fastest pace till date.
According to power ministry estimates, another 8.8 GW capacity is likely to be added in 2017, including about 1.1 GW of rooftop solar installations.
Earlier last month, lower capital expenditure and cheaper credit had pulled down solar tariff to a new low of Rs 2.97 per unit in an auction conducted for 750 MW capacity in Rewa Solar Park in Madhya Pradesh.
The auction was conducted by a joint venture of Madhya Pradesh government and Solar Energy Corporation of India (SECI).
The country has shown it to the world that India is a big market place for manufacturing in solar power sector and international investors and manufacturers have started setting up manufacturing units in the country, Goyal noted.
He also talked about devising strategies to combine solar power with electric vehicles, which have three times the energy efficiency on engines that run on fossil fuels. This would be a revolution in the transportation sector, he added.
