What reviewers said

Buyers beware. I’m surprised there is still a google page for this company. We had such a bad experience with this company that it still leaves a bad taste in my mouth after 3 years. Slick sales people then delay after poor communication after delay after delay ect. Please avoid this company for your own sake.

Working with kota has been a disaster that nearly resulted in a lien being placed on our house before we ever had functional solar panels. They went to great lengths to avoid speaking to us throughout the entire process - for 2 weeks we called everyone from their head of sales downward multiple times a day and were never responded to - and it was only after I got the cantact info for the COO that I was able to speak to anyone. This was all days before a a lien was nearly placed on our property because Kota had not paid their contractors. Kota convinced us to replace our roof in order to get so

I am a disgruntled customer, extremely frustrated with your company’s inability to deliver my solar and roofing project. Still pending resolution to multiple issues. If I don’t hear back, I’ll not be left with choice but to file complaint cslb and take legal measures.

Had a great experience with KOTA and their Rep Skylar Sherier. The system was installed and is working very well. We are generating more power than we are using and at looking forward to a nice rebate check from PG&E in a few more months. I highly recommend listening to Skylar if he wants to give you his sales presentation.

I had a meeting with a Kota sales representative today Skylar, and the presentation was pretty amazing with the tools/apps to break down costs, savings, and timelines. I was very impressed with his knowledge and all of the benefits of "going": solar, plus answers to all of my questions and concerns. Great job.

Trenton Saunders, kota sale team member visited our house around Nov 2020 trying to sell solar system for our house and by Dec 2020 we have Solar system was installed at out roof pulse they have upgraded roof. He smart and has vast knowledge about solar panels. I have got quotes from quite few other solar panels installation companies but they have bet everyone's price.

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.
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.

Who Google shows alongside them

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.
