Websol Energy System Ltd

Websol Energy System Limited, formerly Websol SI Energy Systems Limited was incorporated in February, 1990. The Company's name was later changed to Websol Energy System Limited in September, 2011. The Company is a leading manufacturer of photovoltaic monocrystalline solar cells and modules in India. With a state-of-the-art integrated production facility at Falta SEZ, Sector II, Falta, West Bengal, Websol has steadfastly delivered an advanced product since 1994 - a commitment to quality that customers worldwide have come to trust. In 2011, the Company stepped up its production capacity and doubled its installed PV capacity to 60 MW at manufacturing facility at Falta SEZ, West Bengal. It ventured into the production of monolike wafers to enter the lower end of the market. In 2012, the total installed capacity of the Company was enhanced to 120MW. It further enhanced the power output of modules to 290Wp. The processing of quasi-mono wafers started in 2014-15. The Company installed a new texturing line to graduate to the manufacture of cost-effective multi-crystalline solar cells. The installed capacity was enhanced to 180 MW. Between January and November 2016, 24,500 MW in generation capacity was added in India allowing the total installed capacity to cross the 300,000-megawatt in 2016. Further, some 8,500 megawatts of renewable generation capacity was added in the country between January 2016 and November 2016. In 2016-17, the Company made expansion thereby increasing its production capacity from 100 MW to 200 MW (Cell Line). Further, in 2017-18, it expanded thereby increasing production capacity from 200 MW to 280 MW (Cell Line) and Module line from 90 MW manual line to 250 MW fully automated Module line. In 2017-18, the Company installed new printing line; it started production of 5-bus bar (5BB) cells. Following the installation of a 120 KWp solar power facility connected to the grid in April, 2017, the Company generated more than 1,00,000 units in a year (corresponding to CO2 emission reduction of 97,659 kgs). In 2019-20, the Company achieved 8% cost reduction in solar cell manufacture through reduction in raw material costs, process improvements, productivity improvement and shopfloor energy savings. 550 MW capacity for solar modules have been commissioned in FY 2023-24. The Company commenced the production of newly installed 600 MW Mono PERC cell line at Falta Plant and 550 MW module line in September 2024. The Company commissioned and operated its newly installed 600 MW solar cell manufacturing line in September 2025, which increased the solar cell capacity to 1.2 GW along with 550 MW solar capacity in FY26.
