TP Solar, Tata Power’s solar manufacturing arm, produced 1 GW of solar modules and 0.9 GW of solar cells in the second quarter of FY27, strengthening the company’s domestic manufacturing push from its facility in Tirunelveli, Tamil Nadu.
The company said in a statement that its production during the first half of FY27, from April to September, reached 2 GW of modules and 1.8 GW of cells. The output includes modules compliant with India’s Domestic Content Requirement norms and approved under the Approved List of Models and Manufacturers.
TP Solar operates a 4.3 GW single-location solar cell and module manufacturing facility in Tirunelveli. Tata Power Renewable Energy Ltd, a subsidiary of Tata Power, has invested nearly Rs 4,300 crore in establishing the plant, according to the company.
The facility manufactures modules using TOPCon and Mono PERC technologies. It also produces ALMM-certified modules and DCR modules using cells manufactured at the same plant. These capabilities are intended to support greater domestic integration across the solar manufacturing chain, from cells to finished modules.
The production update comes as India seeks to expand local manufacturing capacity for renewable-energy equipment. DCR compliance requires the use of domestically manufactured components for projects covered by the relevant rules, while ALMM approval determines whether listed models and manufacturers can be used in specified government-linked solar projects. TP Solar’s stated production profile therefore covers both general manufacturing capacity and segments tied to domestic procurement requirements.
The Tirunelveli plant also uses artificial intelligence and machine-learning systems, along with Automated Guided Vehicles, as part of its manufacturing operations. Tata Power described the facility as an advanced manufacturing unit focused on automation and operational efficiency.
The company said nearly 80 per cent of the facility’s workforce comprises women. It presented the workforce profile as part of its focus on inclusive employment alongside the expansion of solar manufacturing capacity.
The scale of the facility gives the production figures significance beyond a single quarterly update. A 4.3 GW plant producing both cells and modules represents an integrated manufacturing base in a sector where domestic supply capacity is central to India’s effort to build a locally supported solar industry. The company’s statement, however, did not provide plant utilisation rates, order volumes, sales figures or details of the projects that will use the output.
TP Solar said the plant’s domestic manufacturing capabilities support Tata Power’s focus on greater self-sufficiency in solar cell and module production. It also linked the facility to India’s broader net-zero carbon ambition through increased local availability of solar equipment.
The company’s next reported production and operational updates will indicate how the Tirunelveli facility’s stated capacity translates into sustained output across the remainder of FY27.
