US solar stocks rise after Trump imposes 15% tariffs on polysilicon imports

US President Donald Trump announced a 15% tariff on imported polysilicon products, a key material for solar panels, aiming to protect domestic solar supply chains from Chinese competition. This move, part of the broader US-China trade tensions involving chips and energy, led to a premarket rise in US solar stocks, including a 7% jump in First Solar shares. The tariffs were imposed under Section 232 of the Trade Expansion Act to strengthen US economic and national security in the polysilicon sector. This action signals increased US efforts to insulate its supply chains and compete with China in technology and energy sectors.
