Rayzon Solar Ltd is set to commence operations at its 5.1 GW TOPCon solar cell manufacturing facility in December 2026, marking a significant step in the company’s efforts to expand beyond module manufacturing and strengthen backward integration.
Initial deliveries from the facility are expected in the first quarter of 2027, the company said in a press release issued on the sidelines of the Bharat Renewable Energy Summit (BRE Summit) 2026.
The Surat-based company, which has an installed solar module manufacturing capacity of 11.3 GW, is also planning a 5.1 GW ingot casting and wafer slicing facility, targeted for development by 2028. It is currently engaging with multiple States to assess incentives and finalise a location for the proposed investment.
The expansion is aimed at building an integrated domestic solar manufacturing chain and reducing dependence on imported inputs.
The TOPCon cell facility marks Rayzon Solar’s entry into cell manufacturing. The company said it remains committed to its manufacturing expansion plans despite shifting the funding for the project from IPO proceeds to debt financing amid market volatility.
Founded in 2017 by Chirag Nakrani and Hardik Kothiya, Rayzon Solar has also completed a 19,800 tonnes per annum aluminium extrusion and anodising unit for manufacturing solar module frames.
On the technology front, the company is pursuing research into tandem-junction technology and nano-coatings for next-generation solar modules, with targeted launches by 2028. Its R&D programme has resulted in three patent filings over the past year.

“The company’s Co-founder, Chirag Nakrani, said the next phase of expansion would focus on the proposed ingot casting and wafer slicing facility. It’s CEO, Amit Barve, told businessline that it expected to bring in high performance modules from its tie up with Caleux Corporation, the US company that has operations in India. Caelux specialises in producing module whose glass has a coat of perovskites, enabling it to catch more wavelengths of the sunlight, increasing electricity generation.
