Last week, the International Trade Commission ruled that the importation of low-cost solar panels meaningfully harmed U.S. manufacturers. The case will now go to President Trump, who will decide whether or not to issue steep tariffs on foreign made panels—a move that would make U.S. solar panels the most expensive in the world and could effectively strangle the industry nation-wide.

Last Friday, the International Trade Commission (ITC) unanimously ruled in favor of a petition issued by U.S.-based Solar panel manufacturers Suniva and SolarWorld to place a $.40/watt tariff on imported crystalline silicon Solar Panels, with a minimum price of $.78/watt, arguing that the glut of inexpensive foreign panels materially harmed the American companies.
