    Seriously the worst experience I have ever had with a company. They were misleading in their sales pitch, promised install in two days (it took 5 months), were impossible to get a hold of with any issues and repeatedly lied to me about what was going on with my rebates and install. They installed one day and then didn't come back for two months to finish, then they had to come back another day weeks later to move the batteries that they installed because they said it didn't meet city code. Which was a lie, they were just too lazy to fix the drawings after they installed them differently than t

    Warning. Have done 2 projects with semper. While they present well, when I later discovered that their work was out of code, they will not return my emails or calls, and are avoiding all responsibility for the problem they have left.

    Nice sales reps until you get the aggressive texting if you don’t buy immediately. 50% higher price than middle bid. Follow up after response from owner: 5 texts in two days is not "a few times". We also turned down the offer and acknowledged we would have considered Semper if they were competitive in pricing. This aggressive text campaign happen months after we rejected your quote.

    The permitting process was long and did not go smoothly. I had to call several times to correct mistakes and follow up. The first installation crew was not professional, however the second one was extremely my good. Ask for Jay!

    Ashlee was amazing to deal with. She was knowledgeable and patiently helped me understand every question I had!

    Semper Solaris is very slow to get you in touch with a representative/advisor (think days). But Angie was very knowledgeable and answered all my questions.

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.

  • Veteran owned

    “expert solar installation. We’re a veteran-owned company, proud to install…”

  • Warranty

    “Cool roof technology & 50 Year warranty HVAC Efficient heating & cooling…”

  • 24/7 availability

    “bills Battery storage Power your home 24/7 Energy efficiency Reduce waste and…”

  • Licensed

    “with smart thermostat support Fully licensed, veteran-led team Bundle HVAC with…”

Its website also mentions free estimate, 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 the Better Business Bureau 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 YouTube, LinkedIn, Pinterest, X, Instagram, TikTok 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.
