Websol Energy System Limited announced on September 23, 2026 that the Government of West Bengal has allotted about 54.20 acres of land to the company at Falta Industrial Park in Kolkata for a planned greenfield solar manufacturing facility.
According to a press release the company filed with the stock exchanges, the new unit is planned with 4 GW of solar cell capacity and 4 GW of solar module capacity. It will be built in two phases of 2 GW each.
The company said the allotment came after it evaluated sites near its existing manufacturing operations at the Falta Special Economic Zone (SEZ). It said expanding within West Bengal would let it draw on more than three decades of operating experience in the state. That experience gives it access to skilled workers, established supplier relationships and close knowledge of the local ecosystem, which the company expects to support faster execution than a plant in an entirely new location.
Websol said the project would also give it a larger integrated manufacturing base in eastern India. It noted that domestic solar manufacturing capacity is expanding to meet India’s growing renewable energy needs.
Sohan Lal Agarwal, Chairman and Managing Director of Websol Energy System Limited, said the solar industry in India was at a very early stage when the company entered manufacturing in the mid-1990s. Solar is now becoming an increasingly important part of the country’s energy infrastructure, he said, and the need for strong domestic manufacturing has never been clearer.
Agarwal described the allotment as the next phase of a journey that began in West Bengal more than three decades ago. He said it would allow the company to build at a much larger scale while staying close to a workforce and operating base it knows well. He added that manufacturing must grow alongside India’s solar capacity, across regions and closer to demand, and called the project Websol’s contribution to a deeper domestic manufacturing base.
Sanjana Khaitan, Executive Director of the company, said the focus now is execution, moving from land allotment to construction, commissioning and utilisation. She said the company has always measured growth by how efficiently installed capacity translates into production, delivery and revenue, not by the capacity alone. The company will keep following that approach as it works towards its 2028 targets, she added.
Founded in 1990, Websol makes solar cells and modules using Mono PERC technology. Its Falta SEZ facility currently has a solar cell capacity of 1,200 MW and a module capacity of 550 MW, and it can process wafers of up to 210 mm. The company supplies cells mainly within India, helping module makers meet Domestic Content Requirement (DCR) norms, and sells its modules in India and overseas.
According to the company, it is one of only 14 solar cell manufacturers in India on the Approved List of Models and Manufacturers (ALMM), and the only one based in eastern India.
