China wants to stop other countries from getting some of its solar panel-making know-how. On Friday, October 17, 2026, China’s Ministry of Commerce proposed China export controls on solar manufacturing technologies. The plan covers 12 technologies. Some would be banned from export, and others would be limited. Here is what is covered, why China says it is doing this, and who could be affected.
What Did China Propose?
The Ministry of Commerce wants to add 12 photovoltaic (solar) manufacturing technologies to China’s export-control list. This is part of a bigger update to the list that also covers artificial intelligence and biotechnology.
The proposal is not law yet. The public can give feedback until November 15, 2026. After that, China will decide whether to go ahead.
Which Technologies Are Covered?
| Type of Control | Technologies |
|---|---|
| Export ban (prohibited) | Technologies for making very thin silicon wafers (no thicker than 70 micrometres), perovskite solar cells, tandem solar cells, and large-scale fluidised-bed polysilicon production |
| Export limits (restricted) | Advanced solar cell manufacturing technologies, including TOPCon, heterojunction (HJT), and XBC |
Fluidised-bed technology matters because it makes polysilicon, a key building block of solar panels, in a way that is cheaper and uses less energy than the usual Siemens process.
What Is Not Covered?
According to one report, the proposed controls apply to manufacturing technologies and equipment know-how. They do not apply to exports of finished solar modules (panels). So the proposal is about the recipes and methods for making solar equipment, not about the panels you put on a roof.
Why Is China Doing This?
China’s Ministry of Commerce says more oversight is needed for national security reasons. It says solar technologies are now being used in sensitive areas such as aerospace and national defence.
Analysts, however, point to another reason. China makes most of the world’s solar equipment and wants to stay ahead. Reuters has reported that Beijing has already limited exports of solar-making technology to India, which is trying to build its own factories and depend less on China.
Who Could Be Affected?
- Countries building their own solar factories: India is the main example in the reports. Other countries that want to set up local production could also find it harder to get Chinese technology.
- Foreign solar manufacturers: The controls could make it harder for overseas companies to expand production at home.
- US companies: Reuters reported in April that Chinese officials held early talks with manufacturers about limits on advanced solar-making technology. It said such a move could threaten plans by US firms such as Tesla to expand production in the US.
What About Pakistan?
Pakistan buys many of its solar panels from China. Since the reports say finished panels are not covered, the proposal does not directly stop panel exports. None of the reports I found discuss Pakistan. Longer term, tighter control of solar technology could affect how many countries set up factories and could influence prices, so this is worth watching.
What Happens Next?
- The public consultation runs until November 15, 2026.
- China reviews the feedback and may change the list.
- If approved, the rules become part of China’s export-control system, and exporters would need to follow them.
Frequently Asked Questions
How many solar technologies does China want to control?
Twelve manufacturing technologies, some banned and some restricted.
Is this rule in force now?
No. It is a proposal. Public feedback closes on November 15, 2026.
Will China stop selling solar panels?
Reports say the proposal targets manufacturing technology and know-how, not finished solar modules.
Why does China say it needs these controls?
China says solar technology is increasingly used in sensitive areas like aerospace and national defence, so it needs more oversight.
Which countries are most affected?
Reports point to India and to countries and companies trying to build solar factories outside China, including US firms.
China’s proposal shows how important solar technology has become to world trade and security. Final rules will depend on the consultation, so watch for news after November 15.
