Websol Energy to Invest ₹3,000 Cr in 8 GW Solar Cell, Module Expansion; Plans Stock Split

Websol Energy Systems’ Board of Directors has approved a phased expansion plan to add 4 GW of solar cells and 4 GW of solar modules through a wholly owned subsidiary. The company, in a press release, said, “This expansion plan will result in a total investment of approximately ₹3,000 crore.”

It further explained, “The capacity expansion plan builds on its existing capacity (Phase I) of a 600 MW solar cell line and a 550 MW solar module line at Falta, West Bengal,” Websol Energy Systems added. The solar cell line is operating at an effective capacity utilisation of 90%. Both these lines were funded through a combination of internal accruals, a preferential issue of equity shares, and lending facilities from financial institutions.”

It added, “An additional 600 MW solar cell line (Phase II), co-located at Falta, is scheduled to become operational in October 2025. This line has been funded entirely through internal accruals and will take Websol’s total solar cell manufacturing capacity to 1.2 GW.”

As part of the company’s overall strategy, Websol Energy Systems said, "The board of Directors has now approved plans to significantly scale up its manufacturing platform in response to the rapidly increasing demand for solar power in India. The additional solar cell capacity will be based on TOPCon technology."

Phased Expansion

Websol Energy said the expansion will be executed in two phases:

1. Phase III: Addition of 2 GW solar cell line and 2 GW solar module line by June 2027
2. Phase IV: Addition of 2 GW solar cell line and 2 GW solar module line by June 2028

Explaining the phased expansion plan, Websol Energy said, "The total investment for Phase III and Phase IV will be financed through a combination of internal accruals and lending facilities from financial institutions. The Board of Directors also approved a stock split in the ratio of 1:10, subject to approval of the Company’s shareholders at the Annual General Meeting to be held on 29th September 2025. 

Commenting on the expansion plan, Sohan Lal Agarwal, Managing Director, Websol Energy System, said, “Websol has always focused on staying ahead of the curve, and this capacity expansion marks a major milestone in our growth journey. From being one of India’s earliest solar cell and module manufacturers, we are now moving into a multi-gigawatt phase of expansion, reflecting our commitment to advanced technologies and an integrated cell and module value chain."

Talking about the phased project implementation, he said, "With Phases III and IV, our solar cell and module capacities will reach 5.2 GW and 4.5 GW by 2028, playing an important role in achieving India’s goal of 280 GW of solar power by 2030. This expansion strengthens our market position in clean energy adoption and our ability to deliver high-efficiency solar-based products. Our integrated facilities with advanced technology represent the future of solar manufacturing in India. As we move forward, we will continue to focus on making solar power more accessible and driving sustainable growth at Websol.”
