India’s Solar Manufacturing Faces Short-Term Crisis After New Domestic Cell Rules

India’s solar manufacturing sector is facing significant disruption after the government introduced mandatory domestic solar cell sourcing requirements from June 1, 2026.

The policy aims to strengthen local photovoltaic manufacturing, but a severe shortage of domestic solar cells has created immediate challenges for many module manufacturers, especially small and medium-sized companies.

Solar Module Producers Forced to Cut Production

According to data from the All India Solar Module Manufacturers Association, nearly one-third of India’s 140 small and medium-sized module manufacturers have completely stopped production. These companies represent around 60% of India’s module manufacturing capacity.

Many remaining manufacturers have significantly reduced operating rates, maintaining only short production cycles due to limited cell availability.

Some companies without in-house cell production capacity are facing waiting periods of 6–8 months for domestic solar cells. Meanwhile, the cost of producing modules with locally manufactured cells has nearly doubled.

Supply Chain Imbalance Creates Bottleneck

The main challenge is the imbalance between module and cell manufacturing capacity.

India currently has approximately 200 GW of nominal solar module production capacity, but domestic solar cell capacity is only around 27 GW, with actual operating capacity estimated at just 16–18 GW.

This gap has created a major supply shortage, leaving many module manufacturers unable to secure enough domestic cells to maintain production.

Industry estimates suggest that building new large-scale cell manufacturing facilities will require 3–5 years to close the supply gap.

India’s Solar Ambitions Face a Critical Test

India’s push for domestic solar manufacturing is part of its broader strategy to reduce dependence on imports and develop a complete renewable energy supply chain.

However, the current disruption highlights the difficulty of rapidly building a self-sufficient PV industry. India still relies heavily on overseas technology, equipment, and manufacturing expertise, particularly from China, which may further slow domestic capacity expansion.

In the short term, India’s solar industry may experience higher costs and slower production. In the long term, the success of its localization strategy will depend on whether domestic cell production can expand quickly enough to support the country’s ambitious renewable energy targets.
