Led by technology and retail giants, corporate America installed and procured nearly 19GW of solar PV capacity through June with sector activity set to accelerate in the next five years because of clean energy goals, falling prices, and federal tax incentives, according to a new report by Solar Energy Industries Association (SEIA).

“About half of all corporate solar has been installed in the last two and half years,” said SEIA CEO Abigail Ross Hopper.
