    I have sent numerous emails to Layla Counts asking for her help with our ccc rebate. This has been going on for months and I never get a response. I am very dissatisfied as we were promised this rebate when we signed our contract with Photon Brothers.

    Had them install a solar and battery system. Have had mixed experiences, but ultimately they didn't stand behind their warranty. I've had to have the powerwall replaced 2 times, the inverter once, the rapid shut down switch once. The system is finally working, but have had leaks from the roof every winter. I had my roof replaced with the panels to not have leaks. After the 4th winter of leaks, each time the roofer would come out and work on it, then it would stop raining, and be back to the start next winter. Finally the roofer said it was the panels, had them taken off and they looked closer.

    I have had horrible customer service with this place. Ordered two tesla batteries in November last year. They quickly installed them (and billed me for them) but they never passed inspection from PGE. It took over 5 months of me bugging them almost daily to remedy the hook up. In the meantime, I missed the window for the rebates they promised. In all, the rebates and tax incentives were supposed cover almost the entire cost of the installation, which is why I signed up. Thus far, the only thing I have seen is the tax savings. None of the rebates have been approved and it is impossible to reach

    When Photon Brothers responds, the job get done pretty quick. Problem is it could take about a week to get a response. Don't know if I could recommend them

    We are new to solar, and the team at Photon Brothers (Service Coordinator Jake and Technician Lucas) were wonderful. Jake worked very hard on our behalf to obtain warranty service from the manufacturer of our inverter panel, and Lucas was extremely helpful during the installation process. He took extra care to ensure that we understood our system. We appreciate both of them very much.

    I have to give a shout out to Photon Brothers. They are a wonderful team! I've had some issues with my solar as I adapted my old system to my new one, and the persistence and troubleshooting of my problem was first class. From Kat, who monitored my solar output from the back end and deployed help when needed, to Ruben who did the onsite electrical work. He went above and beyond, stopping by and calling to checking my solar was working and I am so thankful.I appreciate Theo's excellent troubleshooting and analytical skills behind the scenes and Jake's responsiveness to scheduling service time.

    Took awhile navigating the landscape of changing rebates but they did an excellent job and were very good at adapting. Lowest price system i could find as well

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 free estimate, licensed and licence number, but not in a sentence we can quote cleanly.

    Elsewhere

    • Google also lists this company under roofing. A company that does both roofing and solar can handle the roof work a panel install often needs.
    • It is also reviewed on 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, Facebook and Instagram. 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.

    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.
