Its one and two star share is 1 point above the typical installer in California. Across California, 727 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 54 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

What reviewers said

  • 1★ · around March 2026 · the company replied

    I hired an advanced solar cleaning to clean our solar panels. I requested several times for pictures before and after which were promised. I have no idea how clean the panels are because they never sent it to me after payment or responded to my text.

  • 5★ · around August 2026

    This company is reasonable and reliable. The panels look like mirrors after the service.

    Came on time... Very Professional Crew. Immediate increase in solar production after much needed cleaning

  • 5★ · around August 2026

    Superb job, I had moss and dirt from 13 years of no cleaning. 31 panels. Practically immaculate, and I could see an increase in output from the solar panels.

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.

  • Established

    “your solar panel investments. Since 2018 ASC has been Southern…”

  • Licensed

    “condition of your home’s exterior. Licensed & Insured Solar Cleaning…”

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

Elsewhere

  • It is also reviewed on Yelp and the Better Business Bureau. 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, YouTube, 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.
