CalState Solar is a leading provider of new residential solar home systems installed statewide from San Diego to San Francisco. Contact us today to see why we are your #1 choice for new home solar installations. Has your current solar provider left you stranded on a job site with reschedules and poor time management?.
You will find that CalState solar gives you the perfect experience from communication and customer service, to an efficient, friendly, and professional install. We are family owned and operated, but we have all come from leadership roles at the Nations largest solar companies. We have seen the upsides and downfalls of large scale solar, and have positioned our company to excel in every aspect of the customer experience.
Every new customer starts out with a meeting with either one of our owners, or one of our highly trained consultants. During the meetings, we are much more interested in learning about your goals than to try and give you a standard solar system. Nothing is standard, and it is our goal to make this experience perfect for you.
At Calstate solar, we handle every aspect of your commercial installation. There is no standard system or installation for a commercial property, so every customer we have will receive the same amount of attention to detail. A commercial installation is very detailed, and there is a lot of consideration that goes into every customer we have.

Very unprofessional company. When we were trying to connect our solar, Danielle, the scheduler, scheduled the tech to come out to our house from 1-4pm or else they will not be able to come for a couple of weeks so we took time off of work to stay home for the tech to arrive. The tech never arrived and when we emailed her after 4pm, she emailed us back that the tech "broke down" and that they will email us the next day for an update. At 11:28am, she emailed us that the tech is available from 12-2pm and 10 minutes later, the tech called us telling us that they are only available now. We

Good luck getting someone to answer the phone or respond back to you via email in a timely manner. You may end up waiting weeks, if ever, for this company to send someone out to activate your solar panels. Very unacceptable.

I had my residential 12 panel solar system installed in 2015 by Mark at Calstate Solar. The project went real smooth that I decided to have a 103 panel system designed and installed by Mark on my commercial property in 2016. One of the challenges before contracting with Mark was that no more than one solar panel would need to be removed to access any panel that needed service or replacement. The job was completed and the system worked excellently. I had an email from the monitoring company Enphase notifying me that one circuit on the 103 panel wasn't reporting any production of electricity

This company made an unsolicited call in which, as soon as I said I didn't want the service, the representative made a point of mocking the science behind climate change (telling me how it's those darned politicians who want to save polar bears) and started lecturing me about his political views. With such unprofessional behavior during a sales solicitation, I would not trust this company to exercise sound judgment in their business dealings.

Nick & his team did an outstanding job of planning, installing & connecting our solar system in Temecula. First rate communication throughout the project. Would recommend anyone thinking of solar panels to take a look at Calstate!
