Tata Power, India’s largest integrated energy company, has achieved major success in its rooftop solar business. In the financial year 2025 (FY25), the company completed 1.5 lakh rooftop solar installations. This raised its total rooftop solar capacity to 3 gigawatts (GW) spread across more than 700 cities. This milestone strengthens Tata Power’s leading position in the solar sector.
The company holds a strong 13.1% share of the rooftop engineering, procurement, and construction (EPC) market. Its wide national presence and strong execution skills help Tata Power stand out in the solar industry. The rooftop solar division earned a profit after tax (PAT) of ₹209 crore in FY25. Out of this, ₹100 crore came in the last quarter (Q4FY25), showing strong profits and growing demand.
In FY25, Tata Power added over 2.5 GW of renewable energy capacity across different sectors. About 600 megawatts (MW) came from rooftop solar projects. This shows the company’s important role in expanding clean energy in India. Tata Power also made progress in utility-scale EPC projects, with an order book of more than ₹4,000 crore currently under execution.
Tata Power supports the government’s PM Surya Ghar Yojana, which aims to provide solar power to 1 crore households. The company works closely with state agencies such as Odisha Renewable Energy Development Agency (OREDA), Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA), Assam Power Distribution Company Limited (APDCL), and power distributors in Jaipur, Ajmer, and Jodhpur to encourage rooftop solar use in homes.
The company’s flagship program, Ghar Ghar Solar, Tata Power ke Sang, is active in cities like Jodhpur, Varanasi, Kochi, Coimbatore, and Raipur. It has a strong network of over 600 channel partners and 225 authorized service providers across more than 400 districts. Tata Power also partners with over 20 financial institutions to offer financing options, making solar energy more affordable. So far, the company has helped finance solar projects worth over ₹5,680 crore.
To ensure high quality and control over supply, Tata Power sources solar modules from its advanced TP Solar manufacturing plant in Tirunelveli, Tamil Nadu. The plant operates at over 90% capacity. In FY25, it produced 3,291 MW of solar modules and 846 MW of solar cells. The factory uses modern technologies such as TOPCon, Mono PERC, and bifacial designs. These technologies help produce efficient, DCR-compliant solar modules that deliver better energy output and performance.
