Starting small with a few MWs of solar module production capacity, Alpex Solar Limited now operates at a GW-scale and is also venturing into vertical integration with solar cell manufacturing. As part of TaiyangNews Leadership Talks at Renewable Energy India Expo 2025 (REI 2025), CEO Aditya Sehgal discussed Alpex Solar’s growth and strategy going forward.
Sehgal shared that the company has grown from 35 MW of solar PV module production in 2007 in Himachal Pradesh, to 1.2 GW at present in Greater Noida. An additional 1.2 GW solar module capacity is currently under construction with more planned to follow. Overall, Alpex expects to reach 3.6 GW of module production capacity within the next 6-7 months.
It is also building 2.2 GW of G12R TOPCon cell manufacturing, which was initially planned to be a mono-PERC factory. Sehgal explained that the technology switch was attempted to produce higher efficiency modules and better align with industry trends.
He added that Alpex is preparing for future technologies through forward and backward integration, including EPC and IPP activities under Alpex Green Energies, and green hydrogen R&D under Alpex GH2. Sehgal shared that Alpex has partnered with US-based Sigma Materials to explore the development of silver paste for solar cell electrodes with manufacturing in India.
According to Sehgal, strong government support – such as customs schemes, Domestic Content Requirement (DCR) mandates, and Approved List of Models and Manufacturers (ALMM) – has enabled the company’s growth and the broader rise of India’s solar manufacturing sector.
On market conditions, he says Alpex remains busy with long-term orders despite concerns about overcapacity. For India to advance further, he believes the country must invest more in domestic automation and R&D rather than relying mainly on imported technologies.
