Tata Power Solaroof, the rooftop solar solutions arm of Tata Power Renewable Energy Limited (TPREL), has achieved a major milestone by adding 1 GWp of installed rooftop solar capacity within the first nine months of FY26. With a full-year target of 1.4 GWp, the company is on track to deliver its highest-ever profitability and revenue from the rooftop solar business.

Revenue momentum also accelerated, with rooftop solar sales surpassing ₹1,000 crore in a single quarter for the first time in Q2, a level the company is expected to exceed in Q3 based on current trends.
According to the company, growth was driven by both residential and Commercial & Industrial (C&I) rooftop solar segments. During the nine-month period, Tata Power Solaroof completed over 1.7 lakh rooftop installations, registering a robust 345% year-on-year growth compared to 38,494 installations during the same period in FY25.
