News
According to the latest disclosures with the BSE, Solarium Green Energy Limited has commissioned a solar module manufacturing facility in Ahmedabad, Gujarat, with an installed capacity of around 1 GW (1,000 MW). This development marks the successful implementation of the company’s backward integration strategy, announced in June 2025.
The facility has been set up with fully automated, latest-generation manufacturing machinery at an estimated capex of nearly Rs. 90 crore (excluding working capital). It is a technologically advanced facility, capable of manufacturing large-format G12 solar modules of up to ~725 Wp.
The plant will produce high-efficiency crystalline silicon solar PV modules using technologies such as TOPCon cells, half-cut cells, and bifacial modules, supported by high-precision imported equipment, including tabber-stringers, laminators, and sun simulators.
Given that solar modules account for 50-60 percent of total EPC project costs, the commissioning of this facility is expected to strengthen the company’s supply chain, reduce dependence on third-party suppliers, accelerate execution timelines, and improve margins through captive consumption. It also strengthens Solarium’s positioning as a fully integrated solar solutions provider.
At an estimated utilisation level of around 85 percent, the facility has the potential to generate annual revenues exceeding Rs. 1,000 crore, depending on market conditions and module pricing, particularly if a portion of the output is sold externally. The plant is expected to cater to both in-house requirements and third-party demand, including EPC players and the broader B2B segment.
