Solarium Green Energy Limited, a leading player in India’s rooftop solar segment, has announced its strategic re-entry into solar module manufacturing. The company plans to set up a fully automated, high-capacity manufacturing facility in Ahmedabad, Gujarat, with an annual output of 1,000 MW. The total estimated capital expenditure for the plant is around Rs 700 million, with additional working capital to be arranged in a 3:1 debt-to-equity ratio.

This backward integration initiative is designed to strengthen Solarium’s control over critical components in its engineering, procurement and construction (EPC) business. Solar modules typically account for 50 to 60 per cent of total project costs, and the move is aimed at reducing cost fluctuations, ensuring timely delivery, and improving overall project profitability.

The new facility will manufacture Crystalline Silicon Solar PV Modules using advanced technologies, including TOPCon cells, half-cut cells, and bifacial cells. High-efficiency production equipment such as imported tabber-stringers, laminators and sun simulators will be deployed to maintain top-tier quality standards.

Solarium also plans to begin manufacturing solar mounting structures—approximately 10 per cent of project cost—at its existing Bavla facility in Gujarat, further boosting operational efficiency and project delivery speed.

The plant is part of Solarium’s strategy to address risks linked to global supply chains, including trade disruptions and geopolitical tensions. Once operational, the in-house capacity will meet Solarium’s captive requirements, and any surplus will be sold to other EPC providers and B2B customers.

Commercial operations are expected to begin in the fourth quarter of the current financial year. The company projects that, at 85 per cent capacity utilisation, the facility could generate over Rs 10 billion in annual revenue if the modules are sold externally. By using in-house modules, Solarium anticipates a gross margin improvement of 5 to 8 per cent in its EPC projects.

Chairman and Managing Director Mr Ankit Garg noted that the facility would support Solarium’s ambitions in both B2B and B2G segments, and particularly its expansion in the residential solar market. The move is also aligned with India’s long-term renewable energy goal of reaching 750 GW of solar capacity by 2047.

With automated, future-ready operations and a secure supply chain, Solarium aims to enhance competitiveness and service reliability, positioning itself as a comprehensive solution provider in a fast-evolving solar landscape.
