  Replaced a portion of our roof to place solar panels. Panels started falling off and a roofing professional took picture of errors in installment. Had to pay to get that repaired. Purchased a new furnace from them. Kept smelling burning/gas, thinking it was just “new” furnace burning smell. They installed a furnace not designed for indoors in our garage and had to change it out completely. While gathering quotes for a new attic space furnace, their quote was $20K higher than all other providers. One provider even pointed out multiple other areas needing attention and still came $20K under Semp

  Destroyed my father's roof 6 months before he passed away. Did absolutely nothing to fix the multiple issues they caused -Fried power box -23 broken tile after I told them to tell me if they broke any -system is now useless and they have not done anything. To solve this issue. These are just the facts, do not make the same mistake my Dad did going with a company that knows nothing except to slap panels down and ghost people. Since then fixing their mess seems to be impossible.I will make sure other people are aware. These are the people That they're talking about, when they refer to a solar ep

  How this company has anything other than 1 star from any customer is shocking. Absolutely awful company with horrible customer service and business practices. The fact they attempt to use the "military image" to fake credibility is appalling. Don't trust or listen to your sales person. Likely they will move on from the company after making hefty commissions lieing to you about how great your system will be. Semper Solaris will then pass blame onto them and throw their hands up as its "not their fault, he doesn't work here any more" Next, customer service is a joke. Somehow the "Palisades Fire"

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.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

• Veteran owned

  “installation in Inland Empire . As a veteran-owned solar company , we deliver…”

• 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…”

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

• 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 YouTube, LinkedIn, Pinterest, X, Instagram, TikTok and Facebook. A page that stopped posting years ago tells you something a listing will not.

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.

• —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.
