    Nolan is professional and very responsive!

  • 5★ · around January 2026

    Nolan is very knowledgeable and professional. It was vey easy to set up an appointment with him and he was communicating with us every step of the way. Pigeons were roosting under our solar panels and making a mess everywhere. Nolan was on time and came in and finished putting up the mesh, cleaned our panels, and got rid of the pigeons in no time. My partner loved his work and thought he was a very likeable guy. We will be recommending him to anyone who needs this kind of service.

    What a great experience with Smart Solar Panel Cleaning! The gutters were clogged and they did a great job removing the built up gunk in the pipes. They were fast, and very reasonably priced! Highly recommend them!

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.

  • Warranty

    “the requirements of any preexisting warranty you may have on your solar energy…”

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

Elsewhere

  • Google also lists this company under gutters and pressure washing.
  • It is also reviewed on Thumbtack and Yelp. 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.

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.
