India is becoming one of the world’s top solar marketplaces thanks to its increased focus on renewable energy. With abundant sunlight and increasing government support, solar energy has become a vital component of India’s energy strategy.
The India solar industry is driving this transformation by offering advanced solar solutions, from photovoltaic manufacturing to rooftop installations and large-scale solar farms. These businesses are helping to achieve global sustainability goals in addition to providing for home energy needs. Their innovation, scalability, and efficiency are playing a key role in reducing dependence on fossil fuels and building a cleaner energy future.
In this blog, we will take a look at Top 20 Solar Companies in India.
India Solar Energy Market Trends
The industry for solar energy in India is expanding rapidly because to encouraging regulations, cutting-edge technology, and significant investments. In FY 2024–25, India added over 8 GW of utility-scale solar projects, with Rajasthan (5.14 GW), Gujarat (3.25 GW), and Tamil Nadu (1.30 GW) accounting for 61% of new capacity. Rooftop solar also surged, with around 4.6 GW installed last year-fuelled by the PM Surya Ghar Muft Bijli Yojana.
As of May 31, 2025, India’s total installed solar capacity reached 110.8 GW. Expanders are now integrating battery storage systems and smart grid solutions, especially with extended inter-state transmission charge waivers until 2028.
Early 2025 saw solar generation grow by 32%, contributing 10% of the country’s electricity mix-while coal-fired generation plateaued. With mega solar parks like Bhadla (2.2 GW) and hybrid initiatives in Gujarat, India is well-positioned to meet its ambitious target of 500 GW of clean energy by 2030, transforming the nation’s energy landscape.
