Who are the 10 best solar energy companies in California based on solar company reviews?

SolarReviews helps you find the best solar installer by sharing below the largest collection of consumer solar company reviews of solar panel companies currently operating in California. Some of these solar companies have also agreed to supply live pricing through the site if you request a solar quote, by entering your zip code above.

There are now more solar power companies operating in California than ever before and more choice of solar products and solar installation companies to speak to about a solar system. The solar tax credit, great long term savings, net metering and an abundance of zero down solar lease and solar loan products are making home solar more popular.

Right across the solar industry in the United States consumer reviews have shown that local installers enjoy the highest levels of customer satisfaction. The large corporate solar companies such as Vivint Solar, Solar City Tesla and Sunrun have much lower reviews scores than local solar companies.

The last 5% of the job is the most important. Renova completed our work and the details that satisfied our HOA and responsibilities for the roof. Thework was finished and brought online on the day promised. Our questions were answered and all calls returned with answers. The contracting process was smooth and fell into place. Not much more we could ask.

Awesome, informative & thorough

5.00

Office location: Hayward, CA 94545

I had three solar companies come out in one day to pitch their companies and Robert from Semper Solaris was the only one that gave a presentation from an education point of view and not a sales point of view. Robert was very knowledgeable and helpful and did not try to upsell us. He made sure we understood everything we needed to understand and didnt get too far in the weeds with information. The timeline he gave me in his presentation was exactly on and he was realistic and made sure everything went smoothly and according to plan. He was there to answer any questions I had after the presentation and after the installation came out to make sure that we understood what was happening and answer any follow-up questions that we mightve had with the new equipment and help us with our new equipment. I would recommend Semper Solaris completely and, tell my friends they should use them I am that satisfied.

Philip Ridout Review

Office location: Canoga Park, CA 91303

My son had NRG previously and they were great company so I hired them to do solar on my two homes. Leo was my salesman and he was not high pressured. He explained the benefits of going solar and everything made sense. Installer were very courteous along with Tiffany. They were knowledgeable and professional and do not have a single complaint. It only took few days to add 20 panels on a two story home. Everyone cleaned up after themselves and panels look great by the drone preview when Robert came. I appreciate it NRG sending someone like Robert out to help me get everything started with the app and also what they installed outside. Will use again if I end up getting another property.

Cosmic Solar was superb

5.00

Office location: Valley Center, CA 92082

We chose Cosmic Solar because of their responsiveness, pricing, and quality equipment. They met all our expectations. They did the work efficiently and worked in tandem with their roofing partner, Alfredo's, so that the work was done earlier than expected. They left the house neat and clean. They responded to our questions and concerns promptly. Mary, the office manager, kept us informed about progress. They did a superb job.

The most important thing I can say in this review is: if you want an amazing system from someone who knows what he’s talking about and does exactly what he says, GIVE BALKAR AT NOVAWEST A CALL !! Like most people investing a large sum of money into a solar system I did copious amounts of research on panels and companies and then invited 9 companies out to get quotes. I wanted the best quality panels from a reliable company at a fair installation price. I also wanted a warranty that showed me the company backed their panel’s production for 25 years. There were cheeper options but reliability, system specs, warranty etc only left two companies that stood out: NovaWest and “the other one” (they don’t deserve a mention). And I initially chose “the other one” because their gimmicks got me. After being lied to and ignored for 4 months by the other guys I went back to Balkar at NovaWest, reviewed options and signed a contract. Within 45 days my system was on my roof and turned on making me money before summer even started. Balkar was very exact in his review of my roof and system production capacity. He did exactly what he stated. My June-August electric bill running my AC 24/7 in Clovis with a pool, $18.48! But because NovaWest put the system up in 45 days I was making money in March so I still have true-up credits. Thanks to NOVAWEST.
