The Best Residential Solar Installers in Irvine, California

The city of Irvine has more than 280 sunny days a year. So it hardly comes as a surprise that there’s a history of the city using solar panels. According to The Orange County Register, as of 2018, solar panels have been installed on roughly 15,000 new homes and on 135,000 existing homes in California. Those numbers reflect Irvine’s history as a leader in environmental policy. By 2020, it is projected that every home in California will have solar panels to support the clean energy movement and turn California into the first state to require solar-powered homes. So as solar-powered as Irvine is, the solar market is still going to be growing.

On this list are the top solar contractors capable of providing clean energy solutions to Irvine homes with professionalism and an in-depth knowledge of green energy. The contractors on this list were selected based on stellar customer reviews, awards, affiliations with associations, including the California Solar Energy Industry Association (CAL-SEIA) and the California Solar + Storage Association, as well as rankings in industry publications like Inc. and Solar Power World.
