Raana Semiconductors has signed a preorder agreement with Swelect HHV Solar Photovoltaics, a wholly owned subsidiary of Swelect Energy Systems, to supply CZ12 silicon ingot growers. The equipment will be deployed at Swelect HHV’s 1 GW ingot and wafer manufacturing facility in India.

In addition to supplying the equipment, Raana Semiconductors will support Swelect HHV in process optimization and recipe development. Swelect HHV’s team will also receive training at Raana’s pilot facility to ensure efficient operation and maintenance of the equipment while minimizing downtime.

“Silicon ingot growth is the foundation of the solar value chain. Crystal quality, process stability, equipment uptime and yield at this first step carry through to wafer quality and cell efficiency downstream. They also determine factory utilization and whether the facility achieves its nameplate capacity,” said Raana Semiconductors. “By developing this capability in India using domestically manufactured equipment, we aim to strengthen local manufacturing and reduce dependence on imports.”

Swelect Energy Systems is an India-based solar manufacturer and energy solutions provider with operations spanning PV modules, power electronics, engineering, procurement and construction (EPC), and energy storage. The company expanded its PV module manufacturing capacity to more than 2 GW in September 2026. Tamil Nadu-based Raana Semiconductors is developing domestically manufactured equipment for silicon crystal growth, with its CZ12 ingot growers targeting India’s emerging upstream PV manufacturing sector.

India is seeking to expand domestic ingot and wafer production to reduce its dependence on imports and address gaps in its solar manufacturing supply chain. The country, however, has made limited progress in upstream manufacturing despite rapid expansion in module and cell production .
