China’s proposed controls on solar photovoltaic manufacturing technology have brought a critical vulnerability in India’s domestic manufacturing strategy into focus: the gap between expanding module production and developing the upstream technologies needed to manufacture solar cells and their key inputs. Announced jointly by China’s Ministry of Commerce (MOFCOM) and Ministry of Science and Technology on October 16, 2026, the proposal seeks to add 12 photovoltaic technologies covering polysilicon production, silicon wafer manufacturing and solar-cell manufacturing to the country’s Catalogue of Technologies Prohibited or Restricted from Export. The proposed controls also extend to key and core equipment that carries the specified technologies.
The proposal is part of a wider review covering 40 technologies across artificial intelligence, biomedicine and photovoltaics. China has invited public comments until November 15, 2026. Importantly, the proposed restrictions have not yet become the final revised catalogue. However, a separate interim requirement is already in effect: exporters must register specified technology transfers before export from October 16 until the formal revision takes effect. The requirement covers transfers of technology ownership, authorisation for overseas use of domestic technology and changes that place ownership or actual control of domestic technology with an overseas entity. Technology exports already underway but not completed are also included.
MOFCOM has stated that the measures are intended to address national security concerns arising from the growing use of photovoltaic technologies in sensitive applications, including aerospace, defence, unmanned equipment and high-security infrastructure. It has also clarified that the proposed controls are limited to technologies meeting specified control indicators. Other technologies outside those thresholds and equipment not covered by the announcement are, in principle, not subject to the new requirements. The ministry has described the revision as a regulatory measure that is not directed at any particular country or entity.
For India, the timing is significant because domestic solar manufacturing has expanded considerably at the module and cell stages, while upstream production remains less developed. A Press Information Bureau factsheet published in September 2026 reported that India’s solar module manufacturing capacity had reached 192 GW by June 2026, compared with approximately 30 GW of solar-cell capacity. These figures demonstrate the scale of downstream expansion, but capacity figures alone do not establish self-sufficiency across the entire manufacturing chain.
A NITI Aayog-hosted report prepared by Crisil Intelligence identifies the structural imbalance. It estimates that India’s import dependence is close to 100% for solar-grade polysilicon, above 90% for wafers and above 60% for cells. The report also identifies China’s concentration across the global supply chain: in 2024, the country accounted for 93–98% of polysilicon production, 95% of wafer capacity, 91% of cell capacity and 82% of module capacity. The report notes that India’s manufacturing base remains concentrated in cells and modules, with limited upstream integration. These are report estimates rather than figures independently certified by NITI Aayog, which states that responsibility for the report’s findings and methodology rests with Crisil.
The dependence extends beyond raw materials to the machinery required to establish and operate production lines. TERI’s 2026 report, India’s PV Manufacturing and Its Strategic Inflection Points, says India imports an estimated 70–100% of production equipment used for wafer and cell manufacturing and module assembly. It identifies limited domestic availability of specialised equipment for processes such as polysilicon purification, ingot growth, wafer slicing and cell fabrication. The report also notes that many Indian factories rely on foreign technology providers because of equipment availability and cost considerations. This means that restrictions affecting technology transfers, installation, commissioning, improvements or upgrades could create challenges beyond the initial purchase of machinery.
The potential exposure is therefore not limited to companies planning new manufacturing facilities. Manufacturers seeking to expand existing production lines or move towards more advanced cell technologies may also need access to foreign technical expertise, process knowledge and equipment support. If the final controls cover technologies required for these activities, companies could face additional licensing procedures, sourcing uncertainty or delays in project execution. The actual effect on Indian manufacturers will depend on the final control indicators, the technologies involved in individual contracts and the availability of alternative suppliers.
India has already used policy support to expand domestic photovoltaic manufacturing. The Production-Linked Incentive programme for high-efficiency solar PV modules has an outlay of ₹24,000 crore and has awarded approximately 48 GW of integrated manufacturing capacity across its two tranches, according to the NITI Aayog-hosted report. However, the next stage of the manufacturing push will require more than additional module and cell capacity. Building domestic capabilities in polysilicon, ingots, wafers and specialised production equipment, while diversifying technology partnerships and strengthening research and development, will be important to reduce exposure to concentrated overseas supply chains.
China’s proposal does not amount to a ban on finished solar-module exports, nor does it automatically stop all solar technology transfers to India. Its significance lies in the possibility of tighter oversight over selected technologies and the equipment that embodies them. With the consultation period due to close on November 15, the final scope will determine how significantly the measures affect India’s efforts to move from downstream manufacturing expansion towards a more integrated domestic solar supply chain.
