Solarium Green Energy Limited, a leading name in India’s rooftop solar sector, has announced plans to re-enter solar module manufacturing with a new Rs 700 million facility in Ahmedabad, Gujarat. The plant will have an annual production capacity of approximately 1,000 MW, and will be financed through a debt-to-equity ratio of 3:1, in addition to working capital provisions.

This strategic move marks a significant step in Solarium’s backward integration initiative. In solar EPC projects, solar modules represent roughly 50 to 60 per cent of total project costs. By setting up its own manufacturing line, Solarium aims to reduce cost volatility, improve project execution timelines, and secure a consistent module supply, thereby improving operating margins.

The new plant will produce Crystalline Silicon Solar PV Modules using state-of-the-art automation and technologies such as TOPCon cells, half-cut cells, and bifacial cells. Imported equipment like tabber-stringers, laminators, and sun simulators will be deployed to ensure high efficiency and output quality.

In parallel, Solarium is also initiating in-house production of mounting structures—which contribute around 10 per cent of project cost—at its existing facility in Bavla, Gujarat. This dual manufacturing capacity is expected to bolster the company’s EPC execution capabilities and support timely project delivery.

The move is strategically aligned with efforts to mitigate global supply chain disruptions, trade barriers, and geopolitical uncertainties. By localising the production of core components, Solarium aims to enhance cost control and project efficiency while maintaining flexibility to supply modules to external EPC players and B2B clients.

India’s solar energy capacity is projected to reach 750 GW by 2047, positioning companies like Solarium for long-term growth. The new capacity will also strengthen Solarium’s position in both B2G and B2B bidding processes, while supporting the company’s expansion into the residential segment through consistent quality and integrated service offerings.

The facility, which will feature fully automated operations, is expected to commence commercial production in Q4 of the current financial year.

Ankit Garg, Chairman and Managing Director of Solarium, expressed optimism: “We are thrilled to re-enter the manufacturing space. This backward integration will secure our supply chain and improve profitability. At 85 per cent capacity utilisation, the plant has the potential to generate over Rs 10 billion in revenue, and we expect gross margins to improve by 5 to 8 per cent in projects using in-house modules.”

The initiative marks a milestone in Solarium’s journey toward full-spectrum solar project capabilities, reinforcing its leadership in sustainable energy solutions.
