In Short : India installed 4.9 GW of rooftop solar capacity between January and September 2025, marking a 161% year-on-year surge. Strong policy support, rising demand for residential systems, and rapid uptake under national rooftop programmes drove this expansion. With quarterly additions hitting record highs, rooftop solar is emerging as one of the fastest-growing segments in India’s renewable energy landscape.
In Detail :India added 4.9 GW of rooftop solar capacity in the first nine months of 2025, marking a major leap for the sector and highlighting the country’s accelerating shift toward distributed renewable energy systems. This growth reflects rising awareness, improving affordability, and supportive national schemes.
The 161% year-on-year increase underscores how rooftop solar adoption has expanded far faster in 2025 compared to the previous year. The surge is driven by growing consumer interest and easier access to rooftop installation markets across states.
The July–September quarter proved exceptionally strong, contributing about 2.1 GW of new rooftop capacity in just three months. This stands as the highest quarterly addition recorded so far and indicates a sustained upward trend.
Residential installations formed the bulk of the new capacity, encouraged by government incentives and widespread participation in national programmes aimed at reducing household electricity expenses. This shift has made rooftop solar increasingly mainstream among urban and semi-urban consumers.
Industrial users also showed substantial engagement, contributing around one-fifth of the quarterly capacity. Commercial and institutional segments added smaller but steady shares, reflecting a balanced mix of adoption across consumer categories.
By September 2025, total rooftop solar capacity in the country reached 18.6 GW. Several leading states continued to record strong performance, supported by robust policy frameworks and high consumer participation.
States with limited land availability have been relying heavily on rooftop installations to meet local clean-energy needs. These regions recorded some of the fastest growth rates, demonstrating the strategic value of distributed systems.
Even with impressive progress, challenges remain in meeting long-term programme targets, particularly in areas such as subsidy disbursement and grid-integration processes. Addressing these barriers will be essential for sustaining momentum.
Overall, the significant rise in rooftop installations in 2025 reflects a maturing market, stronger policy push, and increasing consumer confidence. If growth continues along this trajectory, rooftop solar will play a transformative role in India’s clean-energy transition in the coming years.
