Websol Energy System Limited has approved a phased expansion of its solar manufacturing capacity involving a total of 4 GW of solar cells and 4 GW of solar modules through a wholly owned subsidiary. The project is expected to require an investment of about INR 30 billion.
The company currently operates a 600 MW solar cell line and a 550 MW solar module line at its facility in Falta, West Bengal, with the cell line running at 90 percent utilisation. An additional 600 MW solar cell line, also at Falta, is scheduled to begin operations in October 2025. This expansion will take Websol’s total solar cell capacity to 1.2 GW.
The new expansion plan will be executed in two stages. Phase III, scheduled for completion by June 2027, will add 2 GW of solar cell capacity and 2 GW of solar module capacity. Phase IV, due by June 2028, will add another 2 GW of solar cells and 2 GW of modules. The company stated that the additional solar cell capacity will be based on Topcon technology. Financing for both phases will come from a mix of internal accruals and institutional lending.
“Websol has always focused on staying ahead of the curve and this capacity expansion marks a major milestone in our growth journey,” said Sohan Lal Agarwal, Managing Director of Websol Energy System. He added, “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.”
Websol Energy System Limited, established as one of the early manufacturers of photovoltaic cells and modules in India, produces high-efficiency solar cells and modules using Mono PERC technology. Its manufacturing operations are located in the Falta Special Economic Zone in West Bengal, covering about seven acres. The company supplies solar cells primarily within India to support Domestic Content Requirement compliance and markets its modules both domestically and internationally.
