Share

Indian solar manufacturer Insolation Energy (INA Solar) has unveiled its latest n-type TOPCon G12R bifacial (glass-glass) solar modules with power outputs from 610 to 635 Wp and efficiency level exceeding 22%.

Deepak Jain, Chief Technical Officer (CTO) of Insolation Energy, told pv magazine that INA Solar is eyeing major capacities in G12R cell production. The company will begin commercial production of G12R solar cells by September next year, with an initial capacity of 4.5 GW in its Phase 1 rollout. Jain also revealed plans to expand capacity further and pursue backward integration into ingot and wafer manufacturing, signaling a move toward full vertical integration in its solar value chain.

“We have launched our G12R model here and are going ahead with solar cell manufacturing. Within one year, we will start commercial production,” said Jain. “The first phase will be 4.5 GW, and then we plan to add more capacity and expand into ingot and wafer production as part of our strategic roadmap.”

Currently, INA Solar operates with a total module capacity of 5.5 GW, including a 1.5 GW line under installation. The company offers a diverse product portfolio, including monocrystalline and N-type TOPCon modules, under models such as M10R and G12R, available in both DCR (Domestic Content Requirement) and non-DCR configurations.

On market strategy, Jain stated that while India remains its primary focus, the company acknowledges the growing export potential, particularly to the United States. “Today, the US is the most potential market for Indian supplies, but we are currently focusing on the Indian market because of its huge demand,” Jain added.

INA Solar serves utility-scale, commercial, and residential segments, supported by a strong dealer and distribution network across the country.

“We are getting a very good response from the market,” Jain said. “With the G12R series, we aim to strengthen our position as one of India’s leading solar manufacturers.”
