India’s Solar Ambitions: Short-Term Cell Shortage Expected to Fade as Capacity Triples
India’s rapid transition toward renewable energy is hitting a temporary bottleneck as domestic manufacturers scramble to meet the government’s stringent local-content requirements. However, industry leaders remain optimistic, asserting that the current shortage of solar cells is a fleeting phase that will be resolved as significant capacity expansions come online over the next three years.
A Transitional Hurdle
The recent implementation of the Approved List of Models and Manufacturers (ALMM) List-II for solar cells has shifted the industry’s focus toward domestic production. These rules, which mandate the use of locally made cells for various projects—particularly in the rooftop sector—have exposed a temporary mismatch between supply and demand.
Despite having over 200 GW of solar module manufacturing capacity, India’s current domestic cell production capacity stands at approximately 32 GW. Critics who point to this gap as a sign of weakness are missing the bigger picture, says Vineet Mittal, chairman of the Avaada Group.
"The current supply-demand mismatch is only a transitional phase as the market aligns with local content requirements," Mittal noted. "This does not prove that India cannot develop adequate cell capacity; rather, the issue is one of matching technology specifications and procurement schedules."
Driving Toward Energy Independence
The push for "Aatmanirbhar" (self-reliance) in the energy sector is acting as a catalyst for massive capital investment. Industry veterans argue that relying on overseas components leaves India vulnerable to volatile global pricing, shipping disruptions, and trade restrictions.
To mitigate these risks, companies are rapidly scaling up. Avaada, for instance, plans to reach 6 GW of cell-making capacity, focusing on high-efficiency, half-cut cells. Similarly, Vikram Solar is aggressively expanding its operations, targeting 9 GW of domestic solar cell capacity by the end of the 2027 fiscal year.
"Backward integration is the real key to long-term energy security," said Gyanesh Chaudhary, CMD of Vikram Solar. "Backed by strong policy pushes like ALMM List-II, Indian manufacturers are making massive capital investments to bridge this gap permanently."
Market Realignment on the Horizon
Analysts suggest that comparing module capacity to cell capacity is an apples-to-oranges comparison. Not all solar projects require domestic-content-compliant cells, and many module factories do not operate at full utilization rates.
Data from the rating agency ICRA supports this bullish outlook, projecting that India’s solar cell manufacturing capacity will surge to approximately 100 GW by December 2027. This growth is expected to follow a pattern similar to the expansion of module manufacturing, which gained significant momentum once demand certainty was established through clear policy frameworks.
Ravi Verma, a governing council member at the Sustainable Projects Developers Association, emphasized that investor confidence follows policy clarity. "Manufacturing capacity adapts to the certainty of demand," he explained. "ALMM has given module makers more certainty, and a clear framework for making cells locally is encouraging manufacturers to commit capital in the same way."
As India continues its path toward a greener future, the consensus among experts is clear: the current strain on supply is a growing pain, not a permanent structural defect. With substantial investments underway, the nation is well-positioned to secure its solar supply chain and bolster its position as a global leader in renewable energy.
