China is exploring curbs on exports of its advanced solar manufacturing technology to the United States, a move that threatens to disrupt the expansion plans of American firms like Tesla and protect its own 80 percent global market share in solar components.
"Tesla succeeding in its solar self-sufficiency push could prove a nightmare for China's world-leading solar manufacturers," research firm Trivium China said in a recent note, highlighting the stakes for Beijing. Not only would they lose a major potential customer, but they could face the emergence of a formidable new competitor.
The potential restrictions center on high-end equipment for producing more efficient panels, known as heterojunction technology (HJT). The move follows a Reuters report that Tesla was seeking to buy $2.9 billion in equipment from Chinese suppliers, including Suzhou Maxwell Technologies, to support its goal of building 100 gigawatts of solar manufacturing capacity on American soil before 2028.
For investors, the policy threatens US solar installers and developers reliant on Chinese technology, while potentially creating a significant advantage for self-sufficient manufacturers. The decision could increase costs, delay projects, and reshape the supply chain for a critical component of the green energy transition, affecting tech giants like Google and Amazon that are also investing heavily in solar power.
US Solar Ambitions at Risk
The discussions, which have not yet led to a formal rule, represent an escalation in the US-China tech rivalry. Beijing's potential clampdown would follow its move to control rare earth exports a year ago and comes as Washington seeks to onshore key industrial supply chains. Chinese officials have held initial talks with solar equipment makers, including a visit to Suzhou Maxwell Technologies, according to sources cited by Reuters.
The news sent ripples through the solar sector. Shares of Sunrun fell 2.8 percent to $12.11, while Enphase Energy bucked the trend with a slight 0.6 percent gain to $32.18. Israel-based SolarEdge Technologies sank 12 percent, though its decline was compounded by a Goldman Sachs downgrade to Sell from Neutral, with the bank lowering its price target to $31 from $36.
First Solar's Competitive Edge
In contrast, the move could bolster the competitive position of First Solar, which saw its stock decline 2.7 percent to $195.20 on broader market weakness. The Arizona-based company is largely insulated from the proposed curbs because its proprietary thin-film panel technology does not use the crystalline silicon that dominates the Chinese supply chain.
First Solar has been building up its supply chain outside of China, with major manufacturing hubs in the US and India. This independence could become a crucial selling point, allowing it to capture market share from rivals who face potential disruptions and price hikes if China proceeds with the export limits.
