    I highly recommend you get competitive quotes, at least on solar batteries and watch for change orders if you do business with these folks. This is what happened: 1. I had an original contract. 2. The first contract had to be dropped due to items outside of Cal-Solar's control. (Fair enough). 3. Cal-Solar provided an update battery contract to an installation (solar installation) they sourced, they designed, they permitted, they installed, and they completed. 4. Cal-Solar wanted a change order on a system that had no changes and yet Cal-Solar claims the installed system had unknown items. (Kee

    Travis came out months ago, and took pictures. Said that they be back Friday never came back no call no show. Now I hear ads for California Solar Company on YouTube. I have to leave a review. Irritating. Now I'm at full power with DC solar thanks anyways

    salesman was rude and did not have time to answer questions. He was not in the business of giving advice or insight on a project.

    Once again I want to thank you so much for your excellent service. Gabriel and Sam were absolutely amazing. True professionals, respected the property. I couldn't be happier with the work they've done and I will certainly recommend to anybody your company. I would like to also add that your employees that have come to my house on the last two visits are absolutely next level. Amazing so please Thank Sam and Gabriel for the kindness and their hard work, especially when it was hot outside. Please let management know that your employees that have been to my house are absolutely top shelf. Sincere

    This company has installed 26 panels and 3 Tesla batteries for us. They are superb to work with; always follow through; always answer the phone; always courteous and extremely helpful at the house and on the phone. USE THEM. THEY ARE AWESOME!!

    I have worked with four solar companies now. These guys were #1. I would caution all of you that there are a lot of bad solar companies out there. most companies promise you the world send you the bid and then they just can’t make it work. From start to finish these guys work very well and got the job done. I qualified for a battery rebate and they helped me with PG&E. The whole job was super professional. Shout out to Tim, Josh, Gared,Colton and Oliver. (The the first tech too that came out for the initial site survey). I highly recommend this company.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Warranty

    “move to the front of the line with guaranteed support within 2 business days.”
  • Established

    “County and neighboring communities since 2000. Come work with us! 149 E. Main St.,…”

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

Elsewhere

  • It posts on Instagram, YouTube and Facebook. A page that stopped posting years ago tells you something a listing will not.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.

Something wrong here? Tell us and a person will read it.
