Solar power in India
Solar power is an important source of electricity in India. Since the mid-2010s, India has increased its solar power significantly with the help of various government initiatives. By February 2026, India's solar power installed capacity reached 143.6 GWAC. India is one of the world's fastest adopters of solar power, making it the third-largest producer of solar power globally as of 2025, after China and the United States.
India also has some of the world's largest solar parks, including the Bhadla Solar Park in Rajasthan, India's largest and the world's 11th-largest as of 2025, with a capacity of 2,245 MW.
With the provision of allowing 100% foreign direct investment in renewable energy, during 2010–19, the foreign capital invested in India on solar power projects was nearly US$20.7 billion, one of the world's highest invested in a single nation so far. In FY2023-24, India received US$3.76 billion foreign capital, and is executing 40 GW tenders for solar and hybrid projects. India has established nearly 70 solar parks to make land available to the promoters of solar plants. The Gujarat Hybrid Renewable Energy Park, being built near Khavda in the Rann of Kutch desert in Gujarat, will generate 30 GWAC power from both solar panels and wind turbines. It will become the world's largest hybrid renewable energy park spread over an area of 72,600 hectares (726 km2) of wasteland in the desert. As of 2025, the plant has completed to generate around 3 GW of power, and the remaining will be fully completed by December 2026.
The International Solar Alliance (ISA), proposed by India as a founder member, is headquartered in India. India has also put forward the concept of "One Sun One World One Grid" and "World Solar Bank" to harness abundant solar power on a global scale.
