Alpex Solar Strengthens Its Manufacturing Roadmap, Upgrading To 2.2 GW G12R TOPCon Technology For Next-Gen Solar Cells

Alpex Solar Limited, a leading integrated solar energy manufacturer in India, has announced a major shift in its manufacturing roadmap. The company will now upgrade its planned solar cell production from phased PERC technology to the more advanced TOPCon (Tunnel Oxide Passivated Contact) technology, establishing a state-of-the-art 2.2 GW solar cell manufacturing facility. This marks a significant step forward in Alpex Solar’s journey to become a leader in high-efficiency solar cell production.

The new facility, located at Kosi Kotwan, will focus on producing G12R generation TOPCon cells—one of the latest and most efficient types of solar cells currently available. This upgrade positions Alpex Solar among the first few manufacturers in India to embrace this advanced technology, keeping the company at the forefront of innovation in the Indian solar manufacturing sector.

The company has stated that the total additional project cost, approximately ₹136 crore, will be financed entirely through internal accruals. This investment reflects Alpex Solar’s commitment to sustainable and self-reliant growth. By directly transitioning to TOPCon technology, the company avoids the need for future upgrades that would have been required if it had first implemented PERC. This approach helps to eliminate potential production downtime, minimize operational disruptions, and secure long-term profitability.

The expansion will be carried out in two phases. The first phase, with a capacity of 1.4 GW, is expected to begin trial production in the first quarter of FY26-27. The second phase, adding another 800 MW, will follow within six months. Once complete, the entire 2.2 GW capacity will be operational during FY26-27. This timeline is designed to align with Alpex Solar’s expanding module production capacity of 3.6 GW and to ensure readiness for the Approved List of Models and Manufacturers (ALMM) List 2 mandate, which will come into effect in June 2026.

Ashwani Sehgal, Managing Director of Alpex Solar Limited, said that the company’s decision to pivot directly to G12R TOPCon cell production is a strategic move that aligns with global technological trends in solar energy. He noted that TOPCon is rapidly becoming the new global standard for high-efficiency solar cells and that this transition demonstrates Alpex’s commitment to innovation, quality, and long-term market leadership. According to him, this decision will help the company remain technologically competitive while insulating it from the costs and downtime associated with future upgrades.

By implementing the direct-to-TOPCon strategy, Alpex Solar gains both operational and financial advantages. It ensures uninterrupted manufacturing operations, prevents potential revenue loss due to future factory shutdowns, and enhances its ability to meet rising demand for advanced solar solutions. With this transition, Alpex Solar reaffirms its vision to play a key role in India’s renewable energy mission. The company aims to deliver world-class, high-efficiency solar cells and modules that cater to the evolving needs of domestic and international markets, supporting the country’s goal of building a self-reliant and sustainable clean energy ecosystem.
