Indian solar manufacturer Rayzon Solar has said its 5.1GW tunnel oxide passivated contact (TOPCon) solar cell manufacturing facility remains on schedule.
The facility represents the company’s move towards greater vertical integration, expanding its manufacturing operations beyond solar modules into cell production. It is expected to begin operations in December 2026, with commercial deliveries scheduled to commence in the first quarter of 2027.

Rayzon is also evaluating a 5.1GW ingot casting and wafer slicing facility, with development targeted for 2028. The company is in discussions with multiple state governments to assess incentives, infrastructure availability and other strategic considerations before selecting a project location.
Hardik Kothiya, co-founder, Rayzon Solar, said: “India’s solar manufacturing ecosystem is evolving rapidly, and we believe scale, technology and integration will be key differentiators in the years ahead. Our ongoing investments are focused on building capabilities that enhance competitiveness, drive innovation and support the country’s transition to clean energy.”
Rayzon was founded in 2017 and already has an installed solar module manufacturing capacity of 11.3GW. The cell facility nearing completion is expected to strengthen its manufacturing ecosystem, improve supply chain reliability and support demand for high-efficiency solar products in domestic and international markets.
Beyond its solar manufacturing expansion, Rayzon has completed a 19,800 metric tonnes per annum (MTPA) aluminium extrusion and anodising facility for solar module frames.
The company is also advancing research initiatives in tandem-junction technology and nano-coatings for next-generation high-efficiency solar modules.
Headquartered in Surat, Gujarat, Rayzon has expanded its operations beyond India through its US subsidiary, Rayzon Solar USA, as part of its international growth strategy.
Rayzon Solar partnered with US-based Caelux Corporation to incorporate perovskite glass coatings into its solar modules in July 2026. The technology is designed to improve light absorption across a wider range of wavelengths and increase module electricity generation.
In India, the company’s manufacturing operations include its Kosamba facility in Gujarat, while 7,913MW of its module capacity is listed under the Ministry of New and Renewable Energy’s Approved List of Models and Manufacturers (ALMM).
