The report credited the PM Surya Ghar Yojana for expanding rooftop solar capacity. It added that residential rooftop solar is entering a phase of sustained scale-up and there is likely to be a transformative scenario emerging by 2030.
India has reached an installed rooftop solar capacity of 17 GW, according to a report published Wednesday by the Indian Solar Manufacturers Association (ISMA).
Titled Residential Rooftop Solar Market: Market Sizing and Growth Outlook, the report projects that national capacity could climb to 132 GW, supported by the Union government's ongoing emphasis on the PM Surya Ghar Yojana. Annual market demand is anticipated to hit between 9 GW and 15 GW annually leading up to 2030.
Beyond current installations, the study identifies an untapped potential of 115 GW, signaling substantial prospects for local production of inverters, solar cells, balance-of-system components, and modules. The publication indicates that the residential sector is moving into a period of continuous expansion, paving the way for a transformative outlook by the end of the decade.
The analysis also points to the "Affordability Effect," noting that rooftop solar installations are spreading into regions where financial returns were previously less compelling. Government policy initiatives have successfully widened residential access and built a steady demand foundation for local producers, the report states.
Amit Manohar, Secretary General of ISMA, highlighted the impact of the current framework. "PM Surya Ghar has played an important role in expanding residential rooftop solar adoption, particularly in markets where project economics remain challenging," Manohar said. He added that since the program concludes in March 2027, establishing an early framework for a subsequent phase—such as PM Surya Ghar 2.0, ideally by December 2026—would sustain market momentum and offer clearer direction for both consumers and industry participants.
