Trump Taxes Solar Panel Material to Revive U.S. Production

President Trump ordered a 15% tax on imported polysilicon — the key ingredient in solar panels and computer chips — plus a rule that it cannot be sold below a set price, starting in December. A national security review found U.S. polysilicon production fell from half the world's supply in 2005 to under 2% in 2024. China now dominates the market.
