A U.S. trade bill proposes banning imports of Chinese solar inverters, potentially redirecting the $8 billion U.S. market to domestic makers. SolarEdge shares dipped 1.4% while Enphase climbed 1.1% as investors price in a shift toward U.S. suppliers.
Legislation introduced in Congress would bar imports of all solar inverters manufactured in China, citing national security and supply-chain concerns. The measure targets modules above 100 kW capacity and would affect inverters accounting for roughly 40% of U.S. installations.
If enacted, the ban could redirect up to $8 billion in annual U.S. inverter sales toward domestic producers such as SolarEdge and Enphase Energy. Analysts estimate U.S. makers could increase revenues by 20% to 30% over the next 12–18 months.
On the announcement, SolarEdge’s stock fell 1.4% as uncertainty over implementation timing weighed, while Enphase shares rose 1.1% on expectations of near-term order growth. Broader industry stocks saw mixed moves as investors parsed beneficiary lists.
The ban faces potential delays in committee review and legal challenges from trade partners. Even if passed, a 12- to 18-month phase-in period means significant market shifts may not materialize until late 2027.
