Websol Energy System Limited has secured a 54.20-acre land allotment from the Government of West Bengal to establish a greenfield solar manufacturing facility. The site at Falta Industrial Park will host a 4 GW integrated capacity for both solar cells and modules.

The project is designed to be developed in two phases of 2 GW each. This expansion aims to leverage the company's existing operational base in the state, which includes access to skilled manpower and established supplier networks. The move supports the broader objective of strengthening domestic renewable energy infrastructure.

Strategic location and execution focus

The decision to expand in West Bengal builds on Websol's presence in the Falta Special Economic Zone. Sohan Lal Agarwal, Chairman and Managing Director, noted that the company entered solar manufacturing in the mid-1990s when the industry was nascent. He emphasized that the new facility allows for scaling up while remaining close to a familiar ecosystem.

Sanjana Khaitan, Executive Director, highlighted that the primary focus now shifts to execution. She stated that growth will be measured by how efficiently installed capacity translates into production and revenue, aligning with the company's targets for 2028.

Current manufacturing capabilities

Websol is one of only 14 ALMM-approved solar cell manufacturers in India and the sole such manufacturer based in eastern India. Its existing modernized facility operates with the following capacities:

The current facility processes wafers up to 210 mm, optimizing energy output and land use. The company supplies cells primarily within India to support Domestic Content Requirement norms, while modules are marketed domestically and internationally.

What the numbers show

The proposed 4 GW capacity represents a more than threefold increase over the existing 1,200 MW cell capacity. This significant jump highlights a strategic pivot toward large-scale domestic manufacturing to meet growing renewable energy demands. The phased approach of 2 GW per phase suggests a measured capital deployment strategy, balancing rapid expansion with operational efficiency.
