    Terrible lady who works up front. Cheyenne, I think is her name. You'd think that as the face of the company and first point of contact for most people, she'd be somewhat customer oriented. I'd suggest getting a new front office coordinator. Also, after looking thought some responses on some of these low rated reviews - they don't seem to want to take any responsibility for mistakes, misunderstandings, or mishaps on their end. They defend and deflect and put it on on whomever they are responding too. This is not good customer service - Reevaluate

    Extremely Disappointed with Ambrose Solar Our experience with Ambrose Solar was deeply frustrating and disappointing. The issues we faced are outlined below, and I want to emphasize that these are facts, not subjective opinions: 1. Poor Paint Job: The paint job on the installation was subpar, with multiple issues requiring repeated follow-ups to address mistakes. 2. Incorrect System Setup: Despite providing clear information upfront, the system was initially set up for PG&E instead of SMUD, causing unnecessary delays and complications. 3. Unreliable Scheduling: Contractors frequently showed up

    Not dependable and poor customer follow up. I originally posted a poor review because they never got back to me about the power being out during installation while it was over 100 degrees out. In addition, the salesperson never got back to me about the final plan and had to deal with that the day of installation as well. The sales advisor (Vincent) never bothered to call me back at all until after the posted review. NO one did despite me leaving messages. Now to be fair, once they did contact me, I posted the follow up review since they finally contacted me back but then they fell off the grid

    Stephanie in utilities went well beyond the call of duty securing PGE SGIP payment. Bri did a good job as our project coordinator Carson we dubbed Superman, responsive to our questions, problems. He is very conscientious and professional; truly awesome. Mark and Cameron thoroughly explained the system to us taking as much time as needed for our many questions. Adam in sales was very personable, friendly and projected confidence in the company. Ivan did a super job patching the drywall. He worked in an organized and precise manner keeping the mess clean. Marco visited the job site a few times t

    Ambrose was Wonderful!! My Tesla Solar battery failed. I had purchased it from a company that had went out of business, and didn’t know what to do, so I called Tesla. Tesla gave me their list of companies that could help me, and I called Ambrose as they were listed as a “Premier Installer” for Tesla. From my first phone call to Ambrose speaking to Justin, he took it from there, and kept me updated along the way. He handled all the communications with Tesla regarding the warranty, and my new battery. He got me scheduled right away, Jo and Arnulfo were the techs that did the install, and they ar

    Had a lengthy and educational meeting with Jon from Sales. The whole process was within the timeline they setup. We hit a few snags but I think it’s stuff I would have encountered with any solar company. The end result: my PG&E bill has been cut by 90%, and I’m hoping with a few tweaks we can get close to 100%. When I have encountered issues the customer service has been excellent. I would definitely recommend Ambrose.

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

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.

    Its website also mentions warranty, free estimate, established and licence number, but not in a sentence we can quote cleanly.

    Elsewhere

    • Google also lists this company under electrical.
    • It is also reviewed on the Better Business Bureau, ConsumerAffairs and Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
    • It posts on LinkedIn, YouTube, X, Facebook and Instagram. A page that stopped posting years ago tells you something a listing will not.

    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.

    Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

    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.
