China has proposed export controls on 12 solar manufacturing technologies, citing national security. Open for consultation until 15 November 2026, the draft could influence India’s efforts to strengthen domestic solar manufacturing.
China has proposed export controls on 12 solar photovoltaic (PV) manufacturing technologies, raising concerns about access to advanced production processes across the global solar industry. Announced on October 16, 2026, the proposal cites national security concerns, noting the growing use of solar technologies in sensitive sectors such as aerospace and defence. The proposed measures would prohibit exports of certain technologies used in thin silicon wafer, polysilicon, perovskite and tandem solar cell manufacturing, while restricting selected advanced crystalline-silicon cell technologies.
The draft is open for public consultation until November 15, 2026, and the proposed prohibitions and restrictions have not yet formally taken effect. However, interim registration requirements apply to certain overseas technology transfers. Although the proposal does not impose a blanket ban on finished solar panels, it could affect access to manufacturing know-how and equipment-related technologies. This development is particularly relevant to India and other countries seeking to strengthen domestic solar manufacturing and reduce dependence on overseas technology suppliers.
What Has China Proposed?
The proposal would add 12 solar-related technologies to China’s Catalogue of Technologies Prohibited or Restricted from Export. Stakeholders have until November 15, 2026 to submit feedback, and temporary pre-export registration requirements took effect on October 16, remaining in force until the revised catalogue is formally issued. The registration rules already apply to technology ownership transfers, intellectual property licensing arrangements, and changes in control over domestic technologies transferred to foreign entities.
The 12 technologies are divided into two tiers. Prohibited exports cover technologies for manufacturing silicon wafers 70 micrometres thick or less, perovskite and perovskite-silicon tandem solar cells capable of conversion efficiencies of at least 30%, and large-scale fluidised-bed polysilicon production technologies. Restricted exports — requiring licensing rather than outright prohibition — cover specific advanced cell manufacturing processes, including selected TOPCon, XBC, and HJT production technologies, along with associated equipment designs, algorithm models, and programme codes. This two-tier structure means the practical impact will vary by technology and by the final scope of the catalogue after consultation.
Which Solar Manufacturing Technologies Are Affected?
Thin silicon wafers sit at the upstream end of the chain. Wafers thinner than 70 micrometres reduce silicon consumption and production costs, making the technology strategically valuable for cell manufacturers. Perovskite and tandem solar cells represent the next frontier of efficiency: tandem cells stack perovskite on silicon to achieve conversion efficiencies above 30%, well beyond the limits of conventional crystalline-silicon cells. Fluidised-bed polysilicon production is a more efficient route to high-purity polysilicon, the feedstock for wafers.
For TOPCon, XBC, and HJT cells, the restrictions target the specific deposition, diffusion, and electrode-manufacturing processes that determine cell performance and production throughput. Crucially, the proposal governs manufacturing technology and technical know-how, not the export of finished solar modules. A Chinese company could still sell panels abroad; what becomes harder is transferring the processes and equipment drawings needed to replicate advanced production locally. This distinction matters because it targets the longer-term objective of building independent manufacturing capability rather than the immediate availability of solar products.

Potential Implications for India’s Solar Manufacturing Industry
India’s dependence on imported solar components makes the proposed controls relevant to its domestic manufacturing ambitions. China supplies approximately 95% of India’s solar cell imports, valued at around US$1.86 billion in FY2026, an increase of 37%. China also accounted for more than 99% of India’s undiffused silicon wafer imports. Separately, India imported 8.01 billion solar cells in FY2026, up 58% from the previous year, while total solar cell import expenditure increased 95% to ₹27,133.68 crore. Meanwhile, India’s solar module manufacturing capacity reached approximately 233 GW by June 2026, compared with around 38 GW of reported solar cell capacity. This gap highlights the imbalance between module assembly and upstream manufacturing, particularly solar cells and wafers.
The proposed Chinese export controls could create additional challenges for Indian manufacturers seeking to expand domestic cell, wafer, and polysilicon production, especially if new facilities depend on restricted technologies. Existing supply-chain delays have already disrupted some Indian module producers and put investment at risk. However, these disruptions predate the October 2026 proposal, and its additional impact will depend on the final rules and the technologies covered. India’s target of 500 GW of non-fossil electricity capacity by 2030, including approximately 292 GW of solar capacity, strengthens the case for developing a more integrated domestic solar supply chain and reducing reliance on imported manufacturing technologies and components.
Major Indian Solar Manufacturers and Their Expansion Strategies
Effects on Global Renewable Energy Supply Chains
China’s proposed export controls could reshape global solar supply chains by restricting access to selected manufacturing technologies rather than finished solar panels. Countries such as India, the United States, and those in Europe seeking to expand domestic solar production may face additional challenges in developing advanced cell, wafer, and polysilicon manufacturing. Although the proposal could create opportunities for alternative technology providers, its impact will depend on the final restrictions and available substitutes. For manufacturers and investors, technology access, licensing requirements, and upstream capacity expansion will be key factors to monitor. Ultimately, the proposal highlights the growing strategic importance of solar manufacturing knowledge.
What Does the Proposal Mean for Solar Manufacturers and Investors?
Future Outlook
The final scope of China’s proposed export controls following the November 15, 2026, consultation will determine how licensing requirements or export prohibitions affect technology transfers. For India, the outlook will depend partly on whether it can expand solar cell manufacturing capacity to 60 GW by December 2026 and 100 GW by mid-2027 with access to the required technologies and expertise. Globally, manufacturers may accelerate alternative technology partnerships and domestic research and development to reduce dependence on Chinese processes. A key uncertainty is whether non-Chinese equipment and technology suppliers can scale sufficiently to support advanced cell and wafer production without delaying solar manufacturing expansion.
Conclusion
China’s proposed export controls on 12 solar manufacturing technologies highlight a strategic shift toward greater control over advanced manufacturing know-how. Although the proposal does not impose a blanket ban on finished solar panels, restrictions on selected technologies could create challenges for countries seeking to strengthen domestic solar production. For India, the development underscores the importance of expanding solar cell, wafer, and polysilicon manufacturing to reduce supply-chain dependence. The final impact will depend on the scope of the controls following the November 15, 2026, consultation. Ultimately, access to advanced technologies will remain crucial to global solar manufacturing competitiveness and renewable energy expansion.
