Indian solar power hardware manufacturer, TP Solar, a subsidiary of Tata Power Renewable Energy Limited (TPREL), has produced 1GW of solar modules and 0.9 TW of solar cells during Q2 FY 2027 (July-September 2026) from its domestic, single-site facility.
TP Solar’s presence on the Indian government’s Approved List of Models and Manufacturers (ALMM) List-II means its modules and cells meet the DCR (domestic content requirement), offering installers and buyers assurance that the hardware is made in India.

The plant can produce 4.3 GW of TOPCon and Mono PERC solar cells annually.
Tata Power, through its subsidiary, TPREL, invested nearly ₹4,300 crore (US$449 million) to establish the facility in Tamil Nadu. The workforce comprises nearly 80% women, part of TP Solar’s commitment to an inclusive workforce, the company says.
The Approved List of Models and Manufacturers (ALMM) List-II, currently in its 12th revision as of October 2026, is issued by the Ministry of New and Renewable Energy (MNRE). India’s total enlisted capacity currently stands at 37.8 GW, with successive revisions adding to domestic manufacturing capability and reflecting the country’s expanding solar cell manufacturing capacity.
The ALMM was relaxed for two years in February 2023, due to domestic capacity being unable to keep pace with the demand for solar PV production in India at the time, according to the then Minister of Power and New and Renewable Energy, R.K. Singh. However, the go-slow was lifted in early 2024.
New proposals aimed at enhancing the veracity of Indian-made hardware were recently published by MNRE. They detail a standard 14-character nomenclature to identify cell origin, technology, wafer size and efficiency, and appear alongside the manufacturer’s name on all hardware produced by companies on the ALMM List-II.
Tata Power says the increased output from its Tamil Nadu facility reflects the company’s commitment to supporting Indian net-zero carbon ambitions. India’s net-zero target is 2070, and the country’s power generation continues to be dominated by coal (1,517 TWh), despite renewables – of which solar energy accounts for the largest share – generating up to 240.5 TWh as of 2024.
