Its one and two star share is 3 points above the typical installer in the Tacoma area. Across Washington, 29 of the 99 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 86 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

Each mark is one company we hold in the Tacoma area whose Google breakdown has been read, placed by its share of one and two star reviews. CapStone Solar is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

    Outstanding professional service!!! Purchasing a solar solution is a significant investment to say the least. I stepped into the solar market as a rookie with little technical background, and my primary goal to obtain a solar system before the removal of the tax credit in 2026. I began my research with local solar companies and came across Capstone. Upon reaching out for a quote, I was immediately contacted by Jeff, Lacey Operations Manager. He was professional, friendly and thorough in answering my rookie questions and providing me with the foundational background on solar I needed in order t

    Amazing service. Our solar installation and servicing company filed for bankruptcy and our solar wasn’t working. One call to Jeff and he came over, determined we had some blown fuses, and was able to quickly resolve our problem. Highly recommend and will use for all future projects.

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.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • 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.
