Its one and two star share is 2 points below the typical installer in Colorado. Across Colorado, 120 of the 216 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 88 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 August 2026 · the company replied

    This co is not a customer support plz dont go with vanguard solar

  • 5★ · around July 2026

    These guys are great! Within one day spend a lot of time to help me find out if my inverter was shot. They even worked directly with solar edge to see if it was just a reboot. Although I need to now get a new inverter they saved me time, money, and frustration in helping me get a new one. Now just have to have them install. Highly recommend

    It was a pleasure working with Stanley today. He was very knowledgeable and professional. He got right to the Crux of the problem.

    Excellent company, Luke was the lead on my project and did a fantastic job. He was extremely knowledgeable and made my project go smoothly. If you have solar needs this company needs to be your first call.

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.

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.

  • Years in business

    “Clients. Vanguard’s team possesses over 90 years of collective experience in the solar…”

  • Licensed

    “projects throughout the US. Jake is a licensed adjuster in the states of Colorado,…”

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

Elsewhere

  • It is also reviewed on 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 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.
