To address growing need of high efficiency solar cells and modules , the company installed PECVD in 2008 and obtained international certification IEC 61215 and IEC 61730 for 180Wp/220Wp solar modules and increase cell efficiency to 16.5% plus . Cells and module capacity increased to 20MW at our Salt lakh plant and also started 120MW expansion plant at Falta west Bengal .

In 2009, as reject semiconductor wafers became scarce, the company ramped up its capacity to 30MWp to process solar grade wafers by setting up a turnkey state-of-the-art line from Centrotherm, Germany and 30MWp state-of-the-art module assembly line from NPC, Japan . Both lines were set up in a new facility in the SEZ zone in Falta, West Bengal. We achieved cell efficiency of 17.2% in mono crystalline wafers and produced 240 Wp modules. This was among the best levels achieved worldwide during that time. Every year more lines were being added and by 2015 and capacity expanded to 250MW cell line and 250MWp fully automated state-of-the-art module assembly line was set up to convert the cells made into solar panels.

Websol’s manufacturing operations certified as per international standards ISO 9001:2015, 14001:2015 and ISO 45001:2018 to ensure consistence and high quality products to customers while caring environment ,safety &health of employees & society . Our ISO 9001:2015 Quality control processes ensure solar cells and modules meet the required standard for performance and durability.

The company is aligned its mission with government of India objectives to generate 300 GW of power from Solar PV by 2030 and reduce carbon emissions by one billion tonnes by the end of the decade .To address growing need of solar cells and Modules in domestic and international market , the company is expanding solar modules capacity to 550MW and solar cells capacity to 2.4 GW solar cells in two phases .First phase comprise of 600 MW solar cells and 550 MW solar Modules and second phase comprises of 1.8 GW solar cells.

Our top management is continuously putting efforts since 1994 by provide electricity to remote areas through off grid solutions , exploring new market to increase customer base for Solar PV ,increase cell efficiency through process improvement & technical collaboration with advance photovoltaic research institutes , and developing technical skills in fresh engineers through on job training and advance technical training by subject experts . At present 300 plus highly engaged employees are working in production planning , cells and modules manufacturing, maintenance, utilities and electrical to deliver high efficiency solar cells and modules in agreed time line .

All Websol Solar Modules are certified as internal standards IEC 61215,IEC 61730 ,UL1703 and UL61730 .these certifications indicates that a Modules have undergone rigorous testing and and meet specific requirements for performance , reliability and safety . Our ISO and IEC certified modules give consumers and solar developers’ confidence in our quality, safety and performance.
