  Good luck getting this company to come out to fix your system. They will always respond with “we will call you back later” do they call back no they don’t. They claim they won’t make repairs because of distance to send a truck but they had no problem installing it. Getting them to do anything is like pulling teeth. They lied on there contract also. They’re scammers!!! Don’t buy through them. I regret my purchase and all they will respond with is “we are sorry about your experience we will have a representative get a hold of you or reach us” with some number, then they tell you when your done t

  Absolutely terrible solar company. Do yourself a favor and don't trust this company. Paid over $20k for solar panels, only to find out their poor installation caused roof damage and a roof leak. Attempted to allow Kota to fix the issue and follow through with their written contract and warranty but they now have stonewalled us. We're having to seek legal counsel. This company should be ashamed of itself. One of the managers that came to do the final inspection of the issue before they ghosted us took full responsibility, even saying he was concerned about mold because the leak is right above o

  My experience with Kota has been great. All the staff have been very professional and knowledgeable. The process has gone very smoothly and I thank the team for managing through it very quickly and efficiently. Skylar Sheriar was great to work with throughout.

  Skylar Sheriar did a great job educating me all about solar energy and how I could benefit from it. From dissecting my energy bill to explaining the mechanics & science behind the solar energy system I was thinking about having installed, he and the Kota team nailed it. Fast forward a few months and I’m fully up and running with my new solar panels! Already saving a good amount on my monthly bill. Highly recommend Skylar & Kota Energy!

  I worked with Pablo Avila on a solar panel installation, and he was extremely, courteous, responsive, and helpful. He is extremely professional and will answer any questions you may have. If you in need of a solar installation please contact Kota and ask to speak with Pablo Avila and he will be able to assist you with all your solar needs.

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.

• Warranty

  “points Industry leading 25-year warranty on parts, power, and labor. Get A…”

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

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

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.
