Solex Energy has announced plans to set up 5 GW solar cell manufacturing capacity
The plan also includes 10 GW BESS manufacturing in Gujarat under an MoU with the Gujarat government
It estimates an investment of about INR 4,000 crore on these facilities to strengthen its vertical integration
Solex Energy Limited, the Indian solar module producer, has officially unveiled its vertical integration plans targeting 5 GW solar cell and 10 GW battery energy storage system (BESS) manufacturing facilities in Gujarat.
The company signed a memorandum of understanding (MoU) with the Government of Gujarat to invest approximately INR 4,000 crore.
Under the agreement, Solex will develop the 5 GW solar cell manufacturing facility in 2 phases of 2 GW and 3 GW. It will support the manufacturer’s existing 4 GW solar module capacity at its fully automated manufacturing facility in Tadkeshwar, Gujarat. In March 2026, Solex said that the company’s 3.78 GW annual solar PV module manufacturing capacity has been listed in the Approved List of Models and Manufacturers (ALMM) List-I.
Solex says this project will strengthen its role in India’s renewable manufacturing landscape by expanding its footprint into high-value solar cell production and next-generation energy storage systems, calling the 2 ‘critical pillars’ of the global energy transition.
While the company does not specify the cell technology it intends to pursue, it is exploring back-contact technology in collaboration with German cell research institute ISC Konstanz. At REI 2025, Solex introduced a prototype product, calling it TaPi-RC or TaPi rear-contact module with an efficiency of up to 24.6% (see Solex Introduces Prototype BC Module; Shares Expansion Plan At REI 2025).
“Our integrated solar cell and energy storage manufacturing project will strengthen domestic manufacturing capabilities, reduce import dependence, and help build a resilient renewable energy ecosystem for generations to come,” said Solex Energy Limited Chairman and Managing Director Chetan Shah.
In an interaction with TaiyangNews Head of Technology Shravan Chunduri, Shah had earlier shared the company’s plans to reach 10 GW each of cell and module capacity by 2030 along with 2 GW of ingot and wafer production (see TaiyangNews Leadership Talks: Solex Energy Limited At REI 2025).
