Raana Semiconductors Private Limited has signed a pre-order agreement with SWELECT HHV Solar Photovoltaics Pvt. Ltd. (SHPV) for the supply of CZ12 ingot growers. These will be deployed at SHPV’s proposed 1 GW ingot and wafer manufacturing facility. Raana Semiconductors is an Indian technology company focused on developing indigenous crystal-growth equipment for semiconductor and solar manufacturing applications. 
SHPV is a wholly owned subsidiary of SWELECT Energy Systems Ltd. Under the agreement, Raana will also provide process optimisation, recipe development and technical training to support the facility’s commissioning and production ramp-up.
The agreement comes as Indian solar manufacturers look to expand beyond module assembly into upstream manufacturing, particularly silicon ingots and wafers. These stages are critical to the domestic solar supply chain, which continues to have a significant dependence on imported upstream materials.
SWELECT’s planned entry into ingot and wafer manufacturing is part of a broader expansion strategy. In October 2026, the company outlined an investment plan of approximately ₹4,500 crore over three years, including around ₹1,500 crore for its proposed ingot and wafer manufacturing venture.
The company also plans to expand its independent power producer (IPP) portfolio from 180 MW to around 1 GW over the next two to three years.
The proposed 1 GW ingot and wafer facility represents a separate upstream manufacturing initiative from SHPV’s existing solar module operations in Coimbatore, Tamil Nadu. SWELECT’s website currently describes SHPV as operating a 2 GW-plus module manufacturing facility.
Under the agreement, Raana will supply CZ12 ingot growers and provide support beyond equipment installation. This includes process optimisation and recipe development, along with training for SHPV’s technical team at Raana’s pilot facility.
The arrangement is intended to help SHPV establish operating procedures, improve production yields and reduce equipment downtime during the initial manufacturing phase.
Raana develops crystal-growth systems based on the Czochralski (CZ) process, which involves drawing a single crystal from molten silicon to produce ingots. These ingots are subsequently sliced into wafers, which are processed into solar cells.
The company has been developing indigenous CZ equipment for solar and semiconductor applications. In September 2026, it outlined plans to introduce a 12-inch CZ ingot growth machine for the Indian solar market, targeting equipment capable of supporting around 10 GW of solar cell production capacity over three years.
The Raana-SWELECT agreement highlights an emerging segment of India’s solar manufacturing ecosystem: indigenous equipment suppliers.
While domestic manufacturers have expanded module and cell production, scaling ingot and wafer manufacturing will also require access to specialised crystal-growth equipment, process expertise and trained technical personnel.
The agreement could provide an example of how domestic equipment manufacturers and solar producers can collaborate to develop these capabilities. However, the actual impact will depend on equipment delivery, plant commissioning, production yields and the facility’s ability to achieve commercial-scale output.
