Its one and two star share is 1 point above the typical installer in the Victorville area. Across California, 500 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 14 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 Victorville area whose Google breakdown has been read, placed by its share of one and two star reviews. Guasti Solar is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

    Our neighbor installed this windmill I’ve lived in my same house for the last 30 years and for the last probably 15 years since they’ve installed, this it’s been nothing but a noisy noise pollution. It’s horrible you can’t enjoy having our front door open on windy days is the most it is a nuisance to the whole neighborhood

    Good people. Very helpful. Also related to the founder of the town of Guasti by Ontario airport.

    Our solar system quit working months ago and we didn’t know it. One huge Edison bill later, we called Guasti Solar on Monday, they fixed it on Tuesday. The Guasti team are great to work with. What else could you ask for? Thanks a million!

    Guasti Solar help us reduce our stress from off-grid living. We didn't hire Guasti Solar right away. We took their quote to compare to other vendors. What we found is ALL other vendors in Los Angeles, San Bernardino, & Riverside counties wouldn't take our order because we're off-grid. Some vendors (2) even recommended Guasti Solar. After a year of searching for competitors we came back to, and hired, Guasti Solar. Thank goodness we did. From the very beginning, Guasti Solar did everything they said they would do. This is crucial in todays world. They were on time, and extremely professional. J

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

What reviewers keep mentioning

  • wind 4
  • inspection 2

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

    “Since 1988 Guasti Solar is a family-owned and operated business based in Oak…”

  • Established

    “as of 4/1/2025 Serving California Since 1988 Guasti Solar is a family-owned and…”

Its website also mentions better business bureau and licence number, but not in a sentence we can quote cleanly.

Elsewhere

  • It posts on X 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.

  • Option One Solar4.9★ · 373
  • Socal Energy Group, Llc4.9★ · 287

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.
