President Joe Biden is set to use his executive authority Monday to issue a 24-month moratorium on solar panel tariffs designed to bolster U.S. industry. Biden’s actions will pause enforcement of Obama-era anti-circumvention tariffs on solar panels and invoke the 1950 Defense Production Act (DPA) to boost domestic panel manufacturing, the White House announced. The president’s move came in response to complaints from the green energy industry and Democratic lawmakers that an active Commerce Department probe into Chinese companies’ alleged tariff violations was slowing the administration’s clean energy goals.
