Strategic Expansion: Doubling Down on Solar Cell Manufacturing
Websol’s decision to double its solar cell capacity reflects its aggressive growth strategy and confidence in the domestic solar market. The new 600 MW mono PERC cell line, which is part of a broader 1.8 GW roadmap, is being installed at the company’s Falta facility in West Bengal. The line is designed to accommodate future upgrades to TOPCon technology, ensuring long-term competitiveness and efficiency.
The company has already placed orders for critical equipment and made advance payments to vendors. Installation is progressing on schedule, with commissioning expected in early Q3 FY26. Once operational, the new line will significantly enhance Websol’s ability to meet rising demand from solar EPCs and power distribution companies.
Facility Overview: Technology Meets Sustainability
Websol’s manufacturing infrastructure is built with precision and sustainability in mind. The Falta plant spans over 3 lakh sq. ft. and features:
-
Advanced German-engineered systems for ultrapure water, HVAC, and cleanroom air quality
-
Three 600TR York chillers and four Paharpur cooling towers for process cooling
-
10 MVA installed electrical capacity with backup DG systems and industrial UPS
-
In-house 110 KW solar power plant, with plans to scale to 500 KW
-
Environmentally compliant effluent treatment plant designed by Veolia
These systems ensure high-quality production while minimizing environmental impact and operational risks.
Financial Commitment and Market Positioning
The INR 220 crore investment for the new cell line was financed through a mix of equity infusion and strategic borrowings. Websol completed a preferential allotment of shares and secured funding from the Indian Renewable Energy Development Agency (IREDA), demonstrating strong institutional confidence in its growth trajectory.
The company’s recent financials reflect a turnaround, with Q1 and Q2 FY26 revenues aggregating to INR 255.16 crore and net profit reaching INR 64.88 crore. This marks a sharp recovery from the losses incurred during the 18-month shutdown for technology overhaul.
Industry Impact and Forward Outlook
Websol’s expansion comes at a time when India is ramping up its solar manufacturing capabilities to reduce dependence on imports. The company’s upgraded capacity and adoption of mono PERC and bifacial technologies position it to serve both domestic and international markets.
With the new line set to go live in October, Websol is expected to play a pivotal role in meeting India’s ambitious solar installation targets. The company has already received interest from renewable power distribution firms for long-term supply contracts, ensuring robust revenue visibility.
