TP Solar Limited, the solar manufacturing arm of Tata Power Renewable Energy Limited and a wholly owned subsidiary of Tata Power, has reported a strong manufacturing performance during the April–December 2025 period, reflecting steady capacity ramp-up and improving operational efficiency.
During the nine-month period, TP Solar manufactured 2.8 GW of Domestic Content Requirement (DCR) solar cells and 2.9 GW of solar modules. Of the total module output, 2.4 GW comprised DCR modules, while the remaining 0.5 GW consisted of ALMM-compliant modules, highlighting the company’s expanding footprint across India’s regulated solar supply chain.
The performance in Q3 FY26 stood out on a year-on-year basis. TP Solar produced 940 MW of solar cells during the quarter, a sharp increase compared with 196 MW in the corresponding period last year, translating into nearly a fivefold rise. Module production for the quarter reached 990 MW, up from 927 MW in Q3 FY25, marking an approximate 7% year-on-year growth. The numbers point to consistent scaling of operations as the plant moves closer to optimal utilisation levels.
TP Solar operates one of India’s largest single-location solar manufacturing facilities in Tirunelveli, Tamil Nadu, with an installed capacity of 4.3 GW for integrated solar cell and module production. The state-of-the-art facility is equipped with advanced TOPCon and Mono PERC technologies and is capable of manufacturing both ALMM-certified modules and DCR modules using domestically produced solar cells.
Beyond scale and technology, the Tirunelveli plant also reflects Tata Power’s focus on inclusive growth. Nearly 80% of the workforce at the facility comprises women, underlining the company’s commitment to building a diverse and inclusive manufacturing ecosystem alongside industrial expansion.
Tata Power, through TPREL, has invested close to ₹4,300 crore in setting up the Tirunelveli manufacturing unit. This investment is a key step in strengthening indigenisation across the solar value chain and supports the broader national objective of reducing reliance on imported solar components.
