From producing high-tech solar panels to implementing mega rooftop and utility-scale solar projects, these businesses are leading India’s solar revolution. As an investor, a homeowner weighing solar options, or simply someone with a passion for clean energy, this list will provide you with important insights into the top players influencing India’s solar future.
Overview of Solar Companies in India
India’s solar market is experiencing record growth, making it one of the world’s most vibrant solar markets. In 2024, the nation added about 25.2 GW of new solar power capacity, an impressive 204% jump from 2023. Included were 18.5 GW from utility-scale solar projects and 4.59 GW from rooftop solar installations. As of the 2024 year-end, the total installed solar capacity in India is at approximately 98.7 GW, making the country a world leader in solar adoption. With over 177 GW of utility-scale projects in the development pipeline and 142 GW of tenders to be issued in the future, India’s shift to clean energy is accelerating at a fast pace.
Top Solar Firms in India by Segment:
Top Utility-Scale Solar Developers in India
Firms such as Adani Green Energy, ReNew Power, and ACME Solar are leading India’s large-scale solar power development. Adani Green Energy retains the most installed and under-construction capacity. ReNew Power is growing rapidly, whereas ACME Solar had a 130% surge in profits in FY25, due to its robust 6.97 GW project pipeline, of which 2.7 GW is currently operational.
Best Rooftop Solar Companies in India
Rooftop solar is gaining traction on a widespread basis in homes, businesses, and industries. During the first half of 2024, India added 1.1 GW of rooftop solar capacity. Tata Power Solar dominated the market with a 29.2% share, followed by other notable players like Roofsol Energy, Havells India, Kalpa Power, and Mahindra Solarize. All these companies are making solar power more accessible to residential as well as commercial customers.
Leading Solar Panel Companies in India
India’s solar manufacturing landscape is also growing at a fast rate. Waaree Energies is the market leader with a 13.3 GW module manufacturing capacity and 14.1% shipment share in 2024. Global leaders such as Jinko and LONGi have strong shares in the Indian market.
