China’s proposal to restrict or prohibit exports of selected solar photovoltaic manufacturing technologies could have important implications for India’s renewable energy industry. The proposed measures cover 12 technologies associated with the production of polysilicon, silicon wafers and solar cells. They could complicate access to advanced manufacturing processes and technical know-how as India attempts to reduce its dependence on imported solar components.
China’s Ministry of Commerce and Ministry of Science and Technology published the proposal on October 16, 2026, as part of a wider review of technologies subject to export controls. The proposal includes both technologies that could be prohibited from export and others that would require restrictions or government approval. Public consultation is scheduled to continue until November 15, 2026.
The proposed measures target specified manufacturing technologies and related technical knowledge, not a blanket ban on exports of finished solar panels. The final impact will depend on the scope of the measures adopted by Chinese authorities and how they apply to particular technologies, equipment and overseas projects.
What Technologies Could Be Affected?
The proposal covers selected processes used to manufacture polysilicon, thin silicon wafers and advanced solar cells. Polysilicon is a key raw material in the conventional silicon-based solar supply chain, while wafers are processed into cells that convert sunlight into electricity.
Some of the proposed prohibitions involve technologies for producing very thin silicon wafers, certain fluidised-bed processes for manufacturing polysilicon, and selected production methods for perovskite and tandem solar cells.
Perovskite is an emerging solar technology that could improve conversion efficiency. Tandem cells combine different photovoltaic materials, such as perovskite and silicon, to capture a broader range of sunlight. These technologies are attracting interest because they may offer higher efficiency than conventional solar cells, although their commercial deployment depends on manufacturing costs, durability and production scale.
The draft also proposes restrictions on selected manufacturing technologies for advanced crystalline-silicon cells, including TOPCon, heterojunction and back-contact designs. These technologies are important as manufacturers seek to improve efficiency and reduce the cost of electricity generated by solar installations.
The controls could affect technology licensing, equipment-related know-how and technical support for overseas production facilities. They do not, however, amount to a general prohibition on exporting completed solar modules.
Why India Could Face Challenges
India has expanded its solar module manufacturing capacity in recent years, supported by growing domestic demand and policies intended to strengthen local production. However, the supply chain remains unevenly developed.
A report published by the Council on Energy, Environment and Water in May 2026 said India’s module manufacturing capacity had grown considerably faster than its solar cell manufacturing capacity. It estimated module capacity at 173 gigawatts as of March 2026, compared with approximately 30 gigawatts of solar cell capacity.
The gap matters because solar modules require cells, which in turn depend on upstream inputs such as wafers and polysilicon. Limited domestic capacity in these areas leaves manufacturers exposed to imported supplies.
India also relies on foreign suppliers for much of the machinery and technical expertise needed to establish and operate advanced manufacturing lines. If access to particular Chinese technologies becomes more difficult, companies could need to find alternative suppliers, develop local capabilities or invest in research and development.
These adjustments may require additional time and capital. Manufacturers could face higher equipment costs, longer commissioning schedules and greater difficulty adopting the latest cell technologies.
Could the Restrictions Create Opportunities for Indian Manufacturers?
The proposal could strengthen the case for investment in India’s upstream solar manufacturing capabilities. Domestic production of ingots, wafers and cells would help reduce reliance on imported components and allow a greater share of the value chain to be located within the country.
Ingot production involves converting purified silicon into solid crystalline forms, which are then sliced into wafers. Wafers are processed into photovoltaic cells, and cells are assembled into modules. Building capabilities across these stages could make India’s solar manufacturing industry more integrated.
If Indian companies expand domestic production successfully, the industry could benefit from more resilient supply chains, additional skilled employment and opportunities for local equipment suppliers. Research partnerships between manufacturers, universities and technology developers could also help build expertise in advanced production processes.
However, export restrictions alone will not automatically make Indian production more competitive. Manufacturers will still need to manage capital costs, secure reliable supplies of raw materials, develop technical expertise and achieve the scale required to compete with established international producers.
Equipment Shortages Could Raise Costs
One of the biggest challenges is access to specialised machinery and the knowledge needed to operate it effectively. Advanced solar manufacturing requires precision equipment, process control, skilled engineers and continuous improvements to production methods.
The CEEW report found that Indian solar cell manufacturing faces higher capital and consumable costs than Chinese production. It also identified dependence on imported machinery and technical know-how as barriers to improving efficiency and reducing costs.
If technology transfers or equipment-related support become harder to obtain, Indian manufacturers could face delays when setting up new factories or upgrading existing facilities. Alternative equipment suppliers may be available, but changing suppliers can require technical adjustments, staff training and additional testing.
Higher manufacturing costs could also affect the prices of domestically produced cells and modules. This would create a challenge for Indian companies seeking to compete with established suppliers while meeting the growing demand for affordable renewable electricity.
What the Proposal Means for India’s Energy Transition
India’s renewable energy ambitions depend on expanding solar power generation while ensuring that the equipment required for new projects remains affordable and available. A more diversified domestic supply chain could reduce exposure to international trade disruptions and concentrated sourcing.
At the same time, restrictions on access to advanced manufacturing technology could slow the adoption of newer production processes if companies cannot quickly find alternatives. The effect would depend on which technologies are ultimately covered, how quickly Indian suppliers develop capabilities and whether other international partners can provide equipment and technical support.
Government policies supporting manufacturing, research and development, workforce training and local equipment production could become increasingly important. Collaboration with suppliers in other countries may also help Indian companies diversify their sources of machinery and technical expertise.
What Happens Next?
China’s proposal remains subject to consultation, with feedback scheduled through November 15, 2026. The final provisions and their implementation will determine the extent of the impact on solar manufacturers in India and other countries.
For Indian businesses, the development highlights both a risk and a potential incentive. Restrictions could complicate access to selected advanced technologies, but they could also strengthen the economic case for investing in domestic manufacturing and research.
India’s ability to benefit will depend on whether it can close gaps in wafer and cell production, reduce manufacturing costs, improve technical skills and develop a competitive local equipment industry. The proposal is therefore an important development to monitor, but its actual effect on Indian solar manufacturing will become clearer only after the final measures are announced.
