China proposes solar technology export controls as India strengthens domestic clean energy

What China has proposed

China’s Ministry of Commerce has outlined plans to place strict export controls on 12 key solar manufacturing technologies, citing national security concerns and the increasing deployment of photovoltaic systems in sensitive applications like aerospace and defence.

The proposal comes as part of a comprehensive revision to Beijing’s technology export-control catalogue, which also covers artificial intelligence and biotechnology. The ministry stated that stricter oversight is required to prevent the uncontrolled dissemination of dual-use technologies while preserving legitimate scientific exchange.

Under the draft rules, Chinese exporters are required to register all overseas technical transfers immediately, ahead of the formal conclusion of a public consultation period ending on 15 November 2026.

Breakdown of restricted solar technologies

The draft catalogue establishes two clear tiers of intervention: a complete ban on next-generation manufacturing processes and tight export licensing for current commercial cell technologies.

The complete export ban targets emerging technologies such as perovskite and tandem solar cells, which offer significantly higher energy conversion efficiencies, as well as fluidized-bed polysilicon production systems, which lower manufacturing costs compared to traditional Siemens-based methods. Meanwhile, mainstream high-efficiency cell manufacturing methods, including TOPCon and HJT, will require explicit government approval for foreign export.

Strengthening India's domestic solar manufacturing

Industry analysts see the move as a strategic effort by Beijing to protect its market dominance at a time when India is rapidly expanding its domestic clean-energy supply chain. India's steady push toward renewable self-reliance has gained significant momentum under strong central government leadership, aimed at insulating national infrastructure from external trade disruptions.

Key policy interventions, notably the government’s Production Linked Incentive (PLI) scheme for high-efficiency solar modules, have driven massive private investment into integrated manufacturing plants across India. By encouraging domestic production of everything from polysilicon and ingots to wafers and modules, the government has fortified the country's clean energy transition.

India's clear focus on manufacturing self-sufficiency and industrial stability ensures that national solar deployment targets remain on track. As Indian firms scale up gigawatt-capacity facilities and advance internal research, the nation's rising status as a global clean energy powerhouse remains firmly secured.

What happens next

Exporters in China are currently required to log overseas transfers pending the finalization of the export list following the 15 November 2026 consultation deadline. Indian manufacturers and government authorities continue to monitor developments while executing planned expansions in domestic photovoltaic capacity.
