Once completed, TOPCon will represent approximately 55% of Websol’s total cell manufacturing capacity. The project also forms part of the company’s longer-term plan to expand solar cell manufacturing capacity to 4GW in two phases. Module production more than doubled year on year to 103MW in Q1 FY27 from 50MW in Q1 FY26, with module capacity utilisation rising to 81% from 39%. Ingot and wafer integrationThe TOPCon expansion is being developed alongside Websol’s plans to strengthen upstream integration into ingot and wafer manufacturing. In April 2026, Websol added 600MW of monocrystalline PERC P-type bifacial cell capacity at its West Bengal plant to the Ministry of New and Renewable Energy’s (MNRE) Approved List of Models and Manufacturers (ALMM) List-II, taking its total listed cell capacity to 1.2GW.
