India’s rooftop solar sector witnessed significant growth in 2025, led by companies such as Tata Power Solar, Roofsol Energy, and Mahindra Solarize. During the year, the country added approximately 7.1 gigawatts of new rooftop solar capacity, marking a remarkable increase of around 123% compared to the previous year. As a result, the total installed rooftop solar capacity reached about 20.8 gigawatts.

This rapid expansion was primarily driven by the government’s “PM Surya Ghar” initiative, simplified approval processes, and various subsidies and incentives offered by state governments.
The top five companies collectively accounted for around 23.6% of total installations, with Tata Power Solar alone holding nearly 19.2% market share, securing the top position. Roofsol Energy and Mahindra Solarize ranked second and third, respectively. These companies have been actively implementing projects across residential, commercial, and industrial sectors.
The residential segment, in particular, contributed the most to this growth. Increasing consumer interest in solar energy, the desire to reduce electricity bills, and the availability of government subsidies have all played key roles in driving expansion in this segment. Additionally, the commercial and industrial (C&I) sector has also seen rising adoption, as businesses aim to cut costs and transition toward sustainable energy solutions.
Overall, India’s rooftop solar market demonstrated strong growth momentum in 2025, with significant potential for further expansion in the future—especially due to continued policy support and technological advancements.
