Indian PV manufacturer Jaskon plans to operationalise an initial 3 GW of integrated ingot, wafer and solar cell manufacturing capacity in India by the end of 2028, Ivan Saha, Managing Director of Jaskson Engineers Limited, told pv magazine. Saha said the company may subsequently expand its ingot and wafer manufacturing capacity to up to 10 GW and its solar cell capacity to up to 5 GW, depending on market conditions.
The company intends to develop its ingot-wafer and cell manufacturing projects simultaneously, although the cell facility could become operational ahead of the ingot-wafer plant.
Saha said the company’s strategy centres on vertical integration, with the company seeking to control manufacturing quality across the ingot, wafer and cell stages rather than relying entirely on external wafer suppliers.
“By controlling wafer quality and cell quality, we can have greater confidence in the final product,” Saha said.
He explained that silicon wafer characteristics, including oxygen content, dislocation levels and resistivity, can influence downstream cell performance. Producing wafers in-house would allow Jakson to control these parameters and optimise the manufacturing process.
Jakson currently has approximately 1.2 GW of solar module manufacturing capacity. Saha said the company’s current investment focus is on backward integration rather than substantial additional investments in standalone module manufacturing, which he described as a relatively lower-value segment with higher operating costs.
Instead, JAKSON plans to focus on backward integration through ingot, wafer and cell manufacturing. The company may sell cell production to the market or explore arrangements to convert cells into modules, depending on market requirements.
Saha expects substantial consolidation in India’s solar manufacturing industry over the next four years as manufacturers face increasing pressure to compete on technology, product quality and production costs. “I believe a significant amount of consolidation will happen,” he said.
He expects considerable market restructuring as the industry shifts its focus from announced manufacturing capacity to commercially viable production.
Jakson plans to adopt TOPCon 3.0 technology at its proposed 3 GW solar cell manufacturing facility. The technology incorporates additional process steps compared with conventional TOPCon cell manufacturing to improve conversion efficiency.
Saha said the company intends to adopt the technology directly rather than transition through successive technology generations.
“We expect to be among the early adopters of TOPCon 3.0 in India,” he said, noting that akson is targeting initial cell conversion efficiencies of 25.5% to 25.6%.
Saha highlighted the gap between India’s announced solar manufacturing capacity and actual market supply. He said commissioned and ALMM-listed capacity, together with capacity utilisation, provides a more realistic assessment of available production.
According to Saha’s assessment, India has approximately 17 GW of ALMM-compatible TOPCon cell manufacturing capacity. Based on publicly available financial results of select listed manufacturers, he estimated average capacity utilisation at around 60%. Applying this indicative utilisation rate to the estimated capacity would suggest annual production of approximately 10 GW.
However, not all this output is necessarily available to the open market, as some manufacturers use their cell production for captive module manufacturing.
Saha said the distinction between announced capacity and actual market supply creates opportunities for manufacturers with differentiated technology and integrated operations.
“Our focus is on technology and vertical integration, with an emphasis on high-quality, fully automated and high-efficiency manufacturing,” he said.
