Mr. S. L. Agarwal, Founder and Managing Director of Websol Energy System Limited, commenced the business.
Production evolved to 6 inch wafers and modules up to 95 Wp. A quality certificate from ISPRA IEC 61215 standards was obtained.
Production extended to the manufacture of 8 inch wafers. Module output increased to 125 Wp for W1000 type . Capacity enhanced to 3 MW.
International certification obtained for W1000 type modules as per IEC 61215 standards. UL 1703 listing for all W900 type modules. Capacity was enhanced from 3MW to 5MW. Production of 160/190Wp modules began.
Capacity enhanced from 5MW to 10 MW. Started commercial production of W1600 and W2000R type modules . International certification from TUV safety class II for W2000 and W1600 type modules. Industrial site was finalized in SEZ Falta, West Bengal, for 120 MW capacity expansion.
The total installed capacity of the Company increased to 20 MW. Three new products were launched, including W2000R type module .
International certifications IEC 61215 and IEC 61730 were obtained for 180/220Wp type modules and UL and CSA listing for 180/220Wp modules. Installed PECVD technology for silicon nitride anti-reflective coating at the salt Lake plant in Kolkata .Cell efficiency reached to 16.5% plus .
The total installed capacity of the Company enhanced to 120 MW. State-of-the-art production facility installed in Falta Special Economic Zone in West Bengal.Migrated from 125mmx125mm to 156mmx156mm wafers ; enhanced the power output of modules to 290Wp.
Engaged in a tie-up with Renesola (China) for two years to produce cells and modules in their name. The processing of quasi-mono wafers commenced. Installed a new texturising line to graduate to the manufacture of cost-effective multi-crystalline solar cells. Installed capacity enhanced to 180 MW.
Installed new process machines in the cell line to optimise efficiency. Cell efficiency enhanced to 18.30% average. Installed a new printing line with higher productivity along with PECVD, Diffusion and Inox machines. Capacity enhanced to 240MW.
Installed an advanced cell printing line for the commencement of the 5BB cell production. Existing module line was transformed to a fully automated high tech 250 MW module line. Installed 120KW solar power facility connected to a grid.
The new module line was operated with enhanced productivity, increased product and quality efficiency with lower rejections.
Increased the wafer size from 157x157mm to 158.75x158.75mm multi-crystalline, enhancing 7 watts in the 72 cell module.
New 600 MW Mono PERC cell and New 550MW project is under progress . 1.2GW Topcorn cell is under planning and execution phase .
