    I originally contacted Sunpower for my solar project and it was completed my Axia. The entire project has been a nightmare. It started with inappropriate text messages in the middle of the night after signing my contract with the sales rep names Ryan. His card said Sunpower but he in fact worked for another company. I contacted Sunpower originally and did get a response from HR who said they would handle the situation. I never heard bak. I contacted my project manager Colton at Axia regarding the situation. Nothing was done about it. I now can not go back to the sales rep with the current issu

    WARNING!!!!!!!!!!!! Do not use this company. We signed up with the lease program the first part of February. Panels were installed at the end of April. We were told at that time there was a part that needed to be ordered. Finally by May 24th the project was completed. The only reason I feel it was completed is that everyone in the company last day of work was the 25th of May. June 12th we received permission to operated from P.G.E. I called Sun Power and they said they would expedite the “Notice to Proceed” and we would be connected in 24-48 hours. That was 7 days ago. Now we have to communica

    Initial service problems. System did not connect to our Wifi and behaved differently than in the on-line video. Now the control light turned yellow. Service is not reachable (was listening for one hour to "we are experiencing an unusually high volume of calls" and elevator music). I guess that what happens if your product is government mandated and you do not need to care for your customers. Actually giving them an upgrade after they reacted to an e-mail. We will see whether they keep the service appointment. And they actually came on time and it seems to be fixed. So maybe I give them another

    My experience is similar to those on this review. My reports that they provide me have literally NO information on the energy generation. Was able to speak with Customer Service (CS) last July 2022, they mentioned that they were upgrading servers and that my reports should be back up soon. Since then I have sent several emails through to CS and no one has ever responded back to my follow-ups. What good is having solar if you don't know how much you are saving? Update: they worked through my problem. All is restored.

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 and established, but not in a sentence we can quote cleanly.

    Elsewhere

    • It is also reviewed on the Better Business Bureau. 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 Instagram, YouTube, LinkedIn, X and Facebook. A page that stopped posting years ago tells you something a listing will not.

    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.
