PM Surya Ghar holds 132 GW market potential: ISMA

The Indian Solar Manufacturers Association (ISMA) released a report highlighting a massive untapped market for residential rooftop solar, estimating a potential capacity of 132 GW across the country. The association credited the PM Surya Ghar programme for accelerating installations, especially in regions where financial returns have been marginal, and called for early guidance on a possible PM Surya Ghar 2.0 by December 2026.

ISMA’s analysis points to a current installed base of roughly 17 GW and identifies an additional 115 GW of demand that could be captured. The body projects annual rooftop installations of 9‑15 GW between 2026 and 2030, translating into a steady demand stream for domestically produced solar cells, modules, inverters and balance‑of‑system components. The report also notes that the programme is set to run until March 2027, and that continuity beyond that date is essential for investors and manufacturers to plan capacity expansions.

The findings align with the Indian government’s broader push for self‑reliance in renewable energy manufacturing and aim to reduce dependence on imports. By making rooftop solar more affordable, the PM Surya Ghar initiative is expected to broaden access for households nationwide, creating a robust demand base that supports the domestic solar supply chain and contributes to the country’s clean‑energy targets.
