According to the “Q2 2025 India Rooftop Solar Market Report” released by analytics firm Mercom, India added 2.8 GW of rooftop solar capacity in the first half of 2025, marking a 158% increase compared to 1.1 GW during the same period last year.
In the second quarter of 2025, India installed 1.6 GW of rooftop solar capacity, reflecting a 33% growth from the 1.2 GW added in the first quarter and a significant 121% surge compared to the 731 MW installed in the second quarter of 2024. Energy consulting firm JMK Research reported similar figures, noting that India added 3.2 GW of rooftop solar capacity in the first half of 2025 and predicting a total of 7 GW for the full year.
In Q2 2025, the residential sector dominated India’s new rooftop PV installations, accounting for 74% of the total, followed by the industrial sector at 19%, the commercial sector at 6%, and government installations at 0.5%. This remarkable growth was largely driven by the Indian government’s “PM Surya Ghar: Muft Bijli Yojana,” which promotes rooftop solar adoption in households through a dedicated portal, accelerating deployment in the residential market.
Regionally, leading states in India’s rooftop PV market include Gujarat, Maharashtra, Uttar Pradesh, Kerala, and Rajasthan, which together accounted for 64% of total installations. Gujarat, Maharashtra, and Uttar Pradesh were the primary contributors to growth this quarter. As of June 2025, Gujarat alone represented over 27% of the country’s total rooftop PV capacity. Among the states, Assam recorded the highest quarterly compound growth rate, with installations increasing by nearly 24% from Q2 2024 to Q2 2025, indicating that rooftop solar adoption is expanding beyond traditional leading regions. Overall, India’s rooftop PV market remains highly concentrated, with the top ten states accounting for nearly 81% of cumulative installations as of June 2025.
Earlier this year, India’s cumulative solar PV capacity surpassed 100 GW, making it the world’s fourth-largest solar market. Domestic module manufacturing capacity has also skyrocketed, jumping from 2.3 GW in 2014 to over 100 GW by August 2025. Supported by government policies and growing energy demand, India’s rooftop solar market continues to develop rapidly, with significant potential for future growth.
