What reviewers said

  • 5★ · around August 2026

    EcoSun Wash did an awesome job on our solar panels. They were super friendly, knowledgeable, and made the whole process really easy. I especially appreciated how willing they were to answer questions and explain things along the way. After the cleaning, we noticed about a 40% increase in production, which was honestly more of a difference than I expected. Great service, great results, and just genuinely nice people to work with. I’d definitely recommend them to anyone looking to get more out of their solar system.

    They really know their stuff when it comes to solar and were able to answer pretty much any question I had about my system. Honestly, I’m not usually one to write reviews, but these guys made me change my mind.They cleaned my solar panels, and afterward I saw around a 40% increase in production. The whole experience was great from start to finish. They were friendly, easy to work with, took the time to explain things, and made sure everything was taken care of. You can tell they genuinely care about the quality of their work and the people they’re helping. I was really happy with the results a

    Really happy with the service. The price was reasonable, they showed up on time and did a good job. Everything went smoothly and I would use them again.

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.

  • Warranty

    “removal & reinstallation — warranty-safe, solar-specific, and built for…”

  • Insured

    “5-star rated · Licensed & insured · Free thermal scan Get a free…”

  • Licensed

    “· 5-star rated · Licensed & insured · Free thermal…”

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

Elsewhere

  • It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

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.
