Its one and two star share is level with the typical installer in the Oakland area. Across California, 788 of the 1,529 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 419 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    Smart Solar Cleaning did a great and fast job on cleaning my solar panels. In less than a week, I requested a quote, got scheduled, and had the job completed. Went extremely smoothly and Nolan communicated great and did an awesome job cleaning my panels. Highly recommend if you are looking for a good panel cleaning service.

    Nolan was great. Very accomodating, on time, and efficient service!

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.

  • Family owned

    “use Smart Solar Cleaning? We are a family owned and operated business that cares…”

  • Insured

    “that cares about the result. We are a fully insured solar panel cleaning company. You can…”

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

Elsewhere

  • Google also lists this company under gutters and pressure washing.
  • It is also reviewed on Thumbtack. 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 Instagram and Facebook. A page that stopped posting years ago tells you something a listing will not.

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 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.
