WASHINGTON, D.C. - The Solar Energy Industries Association (SEIA) – the national trade association for the U.S. industry - and its members expressed disappointment in the decision by President Trump to impose 30 percent tariffs on imported solar cells and panels. The decision effectively will cause the loss of roughly 23,000 American jobs this year, including many in manufacturing, and it will result in the delay or cancellation of billions of dollars in solar investments.
