Gujarat-based solar module manufacturer Solex Energy has announced an expansion of its 1.5 GW module manufacturing plant in Tadkeshwar, Gujarat, with a new 2.2 GW solar module production line.

The company invested ₹2 billion (~$23.2 million) towards this expansion.

After the production line becomes operational, its total manufacturing capacity is expected to reach nearly 4 GW, with commercial production targeted for September.

The new production line will manufacture tunnel oxide passivated contact (TOPCon) modules utilizing an automated production process. This process includes artificial intelligence, automated optical inspection-driven efficiencies, and a manufacturing execution system for real-time traceability and data analytics.

Solex Energy is partnering with China-based Zhuhai Gmee Solar Equipment to introduce the required technologies.

In March 2025, the company announced full-scale commercial production/operations of its 800 MW solar module manufacturing plant at its facility in Tadkeshwar, Gujarat.

Under its Vision 2030 plan, the company is exploring a new solar cell facility with an initial 2 GW capacity that will be scalable to 5 GW. It also plans to expand its module manufacturing capacity to 15 GW.

According to Mercom’s recently released State of Solar PV Manufacturing in India 2025 report, India added 25.3 GW of solar module capacity and 11.6 GW of solar cell capacity in the calendar year 2024. The manufacturing capacity additions in 2024 were primarily driven by demand from the solar project pipeline and the reimposition of the Approved List of Models and Manufacturers (ALMM) order from April 2024.

Per the report, monocrystalline modules, with or without passivated emitter and rear cell technology, comprised almost 59% of the country’s module production capacity, followed by TOPCon, polycrystalline, and thin-film modules.

In March 2025, the Ministry of New and Renewable Energy expanded the ALMM capacity by adding 8,067 MW of solar module manufacturing capacity. Solar cells will also come under the ambit of the ALMM from June 2026.
