Caelux’s energy-producing solar glass replaces the conventional top glass in a module with a second power-generating perovskite layer, also known as a Hybrid Tandem module. This creates modules with significantly greater power density than conventional silicon-only modules, accelerating the deployment of more clean energy.
“We are dedicated to fulfilling India’s vision of establishing world-class, high-quality solar manufacturing at scale,” said Chirag Nakrani, Co-Founder & Managing Director, RAYZON Solar Limited. “By partnering with Caelux, we are furthering our technology leadership and strengthening India’s position at the forefront of next-generation solar manufacturing.”
Leveraging its 11.3 GW large-scale bifacial manufacturing platform, RAYZON Solar will overlay Caelux’s energy-producing glass on its TOPCon technology to produce the highest power density modules available.
“As India is one of the top solar manufacturing countries in the world, it is a strategic destination for us. This partnership is a critical step in Caelux’s growth trajectory as we look to scale our technology globally,” said Scott Graybeal, CEO, Caelux Corporation.“We are honoured to partner with RAYZON Solar, an award-winning and globally respected solar module manufacturer.”
The companies are currently collaborating on early deployments, and commercial volumes are expected to be available by 2028 and eligible for India’s government-tendered utility market.
Building India’s Domestic Clean Energy Manufacturing Ecosystem
India is experiencing dramatic growth in both solar deployment and manufacturing due to the Production Linked Incentives Schemes from India’s Ministry of New and Renewable Energy (MNRE) combined with the Approved List of Models and Manufacturers (ALMM) listing requirements.
“This partnership accelerates our capability to domestically manufacture at the efficiency frontier and at the scale India needs to meet its ambitious clean energy goals of 500 GW by 2030,” said Amit Barve, CEO, Rayzon Solar Limited.
With facilities in Kim and Kosamba, Surat, Rayzon Solar’s ALMM-listed manufacturing platform provides the scale needed to commercialize the next-generation modules.
“Having spent my career supporting both downstream project development and solar manufacturing, I am excited about the massive impact that this partnership will have for the Indian solar market,” said Vish Iyer, Managing Director, India & West Asia, Caelux Corporation.
