Its one and two star share is 44 points above the typical installer in the Chico area. Across California, 53 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 6 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 Chico area whose Google breakdown has been read, placed by its share of one and two star reviews. Marks Solar is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

    Would recommend 0 stars if I could. I haven’t heard a single good thing about him or his services. I recently purchased a home and wanted to give him a chance, but I just saw a video on my Facebook feed of his company truck plowing through a flock of ducks walking across the highway. I hope he gets what he has coming to him.

    I volunteer at a food back that had solar installed 1.5 yrs ago. There has been things that broke. We have called them multiple times and they were rude and things are still not repaired. Would not recommend this company to anyone.

    Great service over the years. They have installed 3.5 separate systems and fixed a number of small issues I've had. Recently they set up an off grid system that has been working great. Pricing and service have always been top notch, highly recommend.

    Smart, professional, quality work. Business with a heart. This company knows what it's doing and doesn't cut corners. Prompt response and fair price. I don't understand the poor reviews; they must be mistaken for another business... or the people don't check their messages or empty their "mailbox".

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 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.

  • Free estimate

    “come out to the property to provide a free estimate. Once an estimate is agreed upon it…”

  • Bonded

    “power. All my work is licensed and bonded up to $100,000. All job sites will…”

  • Insured

    “save money and energy. As a licensed, insured, and experienced contractor, I offer…”

  • Licensed

    “to save money and energy. As a licensed, insured, and experienced contractor,…”

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

Elsewhere

  • It is also reviewed on Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.

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.
