Emerging Portland solar electronics provider Azuray Technologies has won certification for its “power optimizer” device, which increases power output from photovoltaic solar panels.

The company announced Tuesday, July 5, that TÜV Rheinland, a top certification agency, certified the company’s AP300 power optimizer smart junction box for use in Europe and North America.Azuray says its technological innovation can raise solar energy harvest up to 25 percent by recouping energy lost because of shade that blocks solar panels or from mismatched or soiled solar modules.
