Solex Energy's 2.2 GW Solar Module Line in Gujarat Begins Commercial Production

Gujarat-based Solex Energy has recently commenced commercial production at its 2.2 GW solar photovoltaic module capacity facility in Surat. In a regulatory filing, the company stated that the commenced production on November 24, 2025.

To further advance its solar technology, Solex Energy Managing Director (MD) Chetan Shah recently shared an update on advancing the company’s new TOPCon technology during the last investor call. He mentioned that the company plans to migrate from TOPCon to TOPCon Plus to back contact technology. He added that this aligns with Solex’s latest announcement and its long-term goal to bring in TOPCon for rear technology.

Shah also noted that ISC Konstanz, a Germany-based research and R&D institute, is supporting Solex in devising its strategy and roadmap for advanced solar cell manufacturing technology.

Aligning With Solex’s Long-Term Plans

Solex has scaled back its module manufacturing plants in favour of cell manufacturing to stay aligned with the launch of the ALCM (approved list of cell manufacturers)  regime, which will make DCR modules mandatory from July 1, 2026, for almost all projects. Many firms risk being stuck with module capacities without comparable cell capacity, as domestic manufacturing of cells is still ramping up. Most players are manufacturing to serve their internal requirements, leading to a rush for cell making as well. Currently, the best estimates for cell manufacturing capacity by 2026 end project 50-60 GW capacity, as compared to over 150 GW of module making capacity.      

Chetan Shah has previously expressed the company’s preparedness to manage water and other resource availability, which are key components for setting up a solar cell plant. During the call, Shah explained, “They will monitor the output and quality with a neutral perspective, and they will guide us to ensure that we do not waste a lot of time in ramping up and achieving the highest efficiency for our cell line to ensure better payback and ROI on our cell investment.” Shah had earlier discussed the company's target to commission its 2.2 GW N-Type TOPCon Plus cell line using N-Type TOPCon Plus technology by March 2027.
