Turnkey solar solutions provider Solarium Green Energy has announced its re-entry into the solar module manufacturing space with the establishment of a 1,000 MW facility in Ahmedabad, Gujarat.

The proposed facility will involve a capital expenditure of ₹700 million (~$8.14 million).

The facility’s funding will be raised through a 3:1 ratio debt-to-equity mix. The plant, which will manufacture TOPCon solar modules, is expected to be operational by the end of the fourth quarter of the current financial year.

Solarium Green Energy said the production line would feature imported tabber-stringers, laminators, and sun simulators to ensure high-quality and efficient output.

The manufacturing facility is aimed at mitigating supply chain risks arising from trade-related disruptions, geopolitical uncertainties, and price volatility.

This initiative is a part of the company’s backward integration plan, aimed at improving profitability, securing its supply chain, and enhancing execution timelines for engineering, procurement, and construction (EPC) projects.

Solarium said that in solar EPC projects, the solar module typically constitutes approximately 50% to 60% of the total project cost. By manufacturing its own modules, the company aims to reduce its dependence on third-party suppliers, mitigate cost volatility, and enhance profitability.

Solarium is also beginning in-house manufacturing of mounting structures, which account for roughly 10% of the EPC project costs. This manufacturing will be carried out at the company’s facility in Bavla, Gujarat.

Ankit Garg, Chairman and Managing Director of Solarium, said that at an 85% plant utilization rate, the facility could generate revenue of over ₹10 billion (~$116.4 million) if the modules are sold externally. Using these modules in-house could result in a gross margin improvement of 5%–8% by eliminating third-party markups.

In February this year, Solarium Green Energy won a contract from NTPC Vidyut Vyapar Nigam to install 6,929 kW grid-connected rooftop solar projects at various locations of central armed forces and departments under the Ministry of Home Affairs in Uttar Pradesh (Zone 4).
