    Always cancelling a service, rescheduling and not showing up

    Don't believe their sales representatives they lie a lot just to sell. They gave me estimated time of completion of 30 days, I have been waiting more than 2 months and they still don't have a date to complete the final inspection.

    Project was handled professionally, on time and under budget. No unexpected delays or costs. Response to questions were prompt.

    I had a great experience with Ilum Solar from start to finish. The team was professional, responsive, and explained everything clearly throughout the process. The installation went smoothly and was completed on time. I really appreciate how they kept me updated and answered all my questions, especially regarding the system and how it works after installation. The system is running well so far, and I’m happy with the results. Overall, I highly recommend Ilum Solar if you’re considering going solar. Thank you to the whole team for the great service!

    Installation experience was very good. Crew arrived early and finished the install same day including battery installation. No issues with installation. I’ve asked a couple questions following the installation about the system and it’s performance and have gotten prompt responses every time. The individual who sold me the solar was not the best. As soon as paperwork was done, I was never able to contact him again for questions.

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

    “have a BBB rating of A+ and a 25 year warranty on the work we complete. Our Vision:…”

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.
  • It posts on YouTube, LinkedIn, 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.
