development of solar cells and until now its achievement in India
Answers
Solar power in India is a growing industry. As of 30 April 2017, the country's solar grid had a cumulative capacity of 12.50 GW.[1] India quadrupled its solar-generation capacity from 2,650 MW on 26 May 2014 to 12,289 MW on 31 March 2017. The country added 3.01 GW of solar capacity in 2015-2016 and 5.525 GW in 2016-2017, the highest of any year, with the average current price of solar electricity dropping to 18% below the average price of its coal-fired counterpart.[2][3][4]
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.[5][6][7][8][9] About India's interest in solar power, Prime Minister Narendra Modi said at the 2015 COP21 climate conference in Paris: "The world must turn to (the) sun to power our future. As the developing world lifts billions of people into prosperity, our hope for a sustainable planet rests on a bold, global initiative."[10] India's initiative of 100 GW of solar energy by 2022 is an ambitious target, since the world's installed solar-power capacity in 2014 was 181 GW.[
