California was the American state that added the most solar electric capacity last year, according to a new report from the Solar Energy Industries Association (SEIA).

And the U.S. Solar Market Insight Report 2017 Year-in-Review, compiled by GTM Research and SEIA, revealed that 2017 saw America ‘pass the 50GW milestone’ for entire installed capacity.

“The solar industry delivered impressively last year despite a trade case and market adjustments. “Especially encouraging is the increasing geographic diversity in states deploying solar, from the Southeast to the Midwest, that led to a double digit increase in total capacity,” said SEIA President and CEO Abigail Ross Hopper.
