Websol Energy System Ltd has announced a major phased expansion of its solar manufacturing capacity through a Rs 30 billion investment via a wholly owned subsidiary. The plan includes adding 4 GW of solar cells and 4 GW of solar modules, significantly bolstering Websol’s role in India’s clean energy transition.

The expansion builds upon the company’s existing facilities at Falta, West Bengal, where it operates a 600 MW solar cell line and a 550 MW solar module line. These are currently running at approximately 90 per cent capacity utilisation. An additional 600 MW solar cell line (Phase II), funded entirely through internal accruals, is expected to be operational by October 2025, bringing Websol’s solar cell capacity to 1.2 GW.

To meet growing demand, the Board has approved two new phases:

These will incorporate Topcon (Tunnel Oxide Passivated Contact) technology, known for its high efficiency, and will be funded through internal accruals and institutional financing.

With these additions, Websol’s total manufacturing capacity will reach 5.2 GW for solar cells and 4.5 GW for modules by 2028—making a substantial contribution towards India’s national target of 280 GW of solar power by 2030.

The Board also approved a 1:10 stock split, subject to shareholder approval at the Annual General Meeting scheduled for 29 September 2025.

Mr Sohan Lal Agarwal, Managing Director of Websol Energy, stated:

“This expansion reflects our commitment to technology leadership and scaling solar manufacturing in India. We are not just growing capacity—we’re building a future-ready, integrated value chain that will support India’s renewable energy ambitions.”
