<P> Solar power in India is a fast developing industry . The country's solar installed capacity reached 23 GW as of 30 June 2018 . India expanded its solar - generation capacity 8 times from 2,650 MW on 26 May 2014 to over 20 GW as on 31 January 2018 . The 20 GW capacity was initially targeted for 2022 but the government achieved the target four years ahead of schedule . The country added 3 GW of solar capacity in 2015 - 2016, 5 GW in 2016 - 2017 and over 10 GW in 2017 - 2018, with the average current price of solar electricity dropping to 18% below the average price of its coal - fired counterpart . </P> <P> In January 2015 the Indian government expanded its solar plans, targeting US $100 billion in investment and 100 GW of solar capacity (including 40 GW from rooftop solar) by 2022 . India's initiative of 100 GW of solar energy by 2022 is an ambitious target, since the world's installed solar - power capacity in 2017 is expected to be 303 GW . The improvements in solar thermal storage power technology in recent years has made this task achievable as the cheaper solar power need not depend on costly and polluting coal / gas / nuclear based power generation for ensuring stable grid operation . </P>
