    I dont know who is rating this company so high, but they deserve a 0 star rating. Once they got you, they WILL NOT be there to fix, you can forget about returning emails or calls. You are stuck in limbo with a system you'll be paying many years on without any type of customer service. Ive had it and now I have to go through the better business bureau and the Solar protection agency. Read the BBB complaints to confirm what im stating. All the bad reviews must have been cleared out.

    Extremely happy with experience from beginning to end. All staff, especially Dan were very professional and easy to work with. Highly recommend.

    I have to give a shout out to Simon C. He's the sales lead on my parents solar system. He went above and beyond his job description to figure things out for us. We ended up with a lot of questions regarding the system and instead of going through customer service, he was able to answer them or get things done without going through hoops. A good sales person should always be knowledgeable about what they are selling and how it operates; and he has the knowledge to back up his products. You'll know you're in good hands with Simon. The pain point with solar is dealing with the city and Edison (po

    6 companies later we settled on Solarmax and it was worth the due diligence. Had our pool installed and our home fence upgraded at the same time. By far the most professional of the 3 groups. Arrived on time and finished on time. I can't state the same of the other two whom still have not finished.

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

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.

  • 24/7 availability

    “energy systems that support critical 24/7 data operations with solar, storage,…”

  • Established

    “record Active in utility-scale EPC since 2014, with 400 MW completed or in…”

Its website also mentions financing, years in business and licence number, but not in a sentence we can quote cleanly.

Elsewhere

  • It is also reviewed on 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, X, Instagram 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.

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.
