"Grew Solar and Caelux Corporation (Caelux) announce a 4 gigawatt (GW), five-year commercialisation partnership to produce high-power Hybrid-TandemTM solar modules with Caelux's energy-producing glass," the statement said.
The supply is expected to start by 2028, with Caelux starting commercial production of the glasses at the proposed facility in India.
Hybrid-TandemTM solar modules are capable of capturing a significantly wider spectrum of sunlight to convert it into clean energy.
Vinay Thadani, CEO and Director, GREW Solar, said partnering with Caelux enables the company to provide next-generation, high-power modules to the market using its gigawatt-scale manufacturing platform.
Gujarat-based Grew Solar operates a 6.5-GW solar PV module manufacturing facility in Dudu, Rajasthan.
The company is in the process of scaling up module manufacturing capacity to 11 GW, besides setting up an 8-GW solar cell manufacturing facility in Narmadapuram, Madhya Pradesh, along with ingot and wafer lines of similar capabilities.
