Websol Energy System Limited has shifted the proposed location of its Phase 3 solar manufacturing expansion from Andhra Pradesh to West Bengal, with the company now working to secure land near its existing facility at Falta.
The company said the decision was driven primarily by the operational and supply-chain synergies available around its established manufacturing base in West Bengal. Websol has operated in the state for more than three decades and expects the existing ecosystem to help accelerate project execution while reducing certain costs.
The company’s overall 4 GW expansion plan remains unchanged. The additional capacity will be developed in two phases of 2 GW each, rather than separate 4 GW capacities for solar cells and modules.
The project was earlier planned at Naidupeta in Andhra Pradesh, where Websol had spent around six months on preparatory activities, including an MoU, approvals, project layout, equipment planning and team identification. However, the company said there had been no financial outflow towards land acquisition in Andhra Pradesh.
Websol expects to secure land approval during Q2 FY27, with construction potentially beginning around mid-September 2026. Construction is expected to take approximately nine months. Equipment ordering is planned around December, with machinery expected to arrive during April-May, followed by around two months of trial operations.
According to company management, the relocation is not expected to alter the broader expansion timeline, project cost or funding strategy. Websol expects the West Bengal location to provide advantages in infrastructure, skilled manpower, supply-chain access and operational resources. Lower land costs and the ability to leverage its existing workforce could also help improve project economics.
The expansion comes as Websol’s existing manufacturing operations are running at high utilisation. During Q1 FY27, the company produced 259 MW of solar cells, compared with 126 MW in the year-ago period, taking cell utilisation to 92%. Module production increased to 103 MW from 50 MW, while module utilisation rose to 81%.
Websol reported Q1 FY27 revenue from operations of ₹373 crore, up 70% year-on-year from ₹219 crore. EBITDA increased 21% to ₹126 crore, while profit after tax rose 16% to ₹78 crore. However, the higher contribution from modules, which carry lower margins than cells, reduced the EBITDA margin to 34% from 47% a year earlier.
As of June 30, 2026, Websol had a confirmed order book of ₹1,278 crore, compared with ₹1,161 crore at the end of March. The company said demand remains strong in the domestic content requirement (DCR) market, particularly across projects linked to government programmes such as PM Surya Ghar and PM-KUSUM.
Before beginning the larger expansion, Websol is upgrading an existing Mono PERC cell line to TOPCon technology. The upgrade is expected to raise capacity from 600 MW to 750 MW, adding around 150 MW. The project, estimated to cost ₹270 crore, is targeted for completion by March 2027.
The TOPCon upgrade is also expected to provide Websol with operational experience in the technology ahead of its larger greenfield expansion. The company remains focused on executing the planned 4 GW capacity addition while scaling its existing operations and responding to growing demand for solar and solar-plus-storage projects.
