In Short : India may face a solar cell shortage from June as new local sourcing rules take effect, requiring domestically manufactured cells for projects. Industry bodies warn that limited domestic capacity, heavy reliance on imports, and technology gaps could delay projects, raise costs, and challenge India’s renewable energy expansion plans during a critical growth phase.
In Detail : India is likely to face a significant disruption in its solar supply chain as new domestic sourcing rules come into force from June. These regulations mandate the use of locally manufactured solar cells in projects, marking a major policy shift aimed at reducing dependence on imports and strengthening domestic manufacturing.
The concern stems from a clear mismatch between demand and available domestic capacity. India currently has solar cell manufacturing capacity of around 25–26 GW, while annual demand is estimated to be close to 50 GW, creating a substantial supply gap that could impact ongoing and upcoming projects.
A major challenge lies in India’s reliance on imports, particularly from China, which currently accounts for over 90% of the country’s solar cell supply. With the new rules restricting such imports for compliant projects, developers may struggle to source sufficient quantities of eligible domestic cells.
The situation is further complicated by technology limitations within domestic manufacturing. A large portion of locally produced solar cells uses older technologies that are not widely preferred in modern solar projects, resulting in a mismatch between available supply and project requirements.
Industry bodies have warned that immediate enforcement of these rules could lead to severe supply shortages. This, in turn, may disrupt project timelines, delay commissioning schedules, and create bottlenecks across the solar development pipeline at a time when capacity additions are accelerating.
Another key impact is likely to be on costs. Limited supply of compliant domestic cells could drive up solar module prices, increasing overall project costs and potentially affecting tariff competitiveness in future renewable energy bids.
To mitigate these risks, industry stakeholders have urged the government to consider a phased implementation. They have suggested delaying full enforcement by several months, allowing approximately 50 GW of domestic cell manufacturing capacity currently under construction to become operational.
The policy itself is part of a broader strategy to build a self-reliant solar manufacturing ecosystem in India. By mandating domestic sourcing, the government aims to boost local industry, create jobs, and reduce long-term dependence on global supply chains, particularly from a single dominant supplier.
