What reviewers said

  • 5★ · around February 2026

    Erik and team are absolutely wonderful. Professional, educational, and easy to work with. Highly recommended!

  • 5★ · around August 2025 · the company replied

    Greatful Sun Energy is the best solar company to go with. My panels and system was installed in a timely manner. And the only thing that took me a little longer than expected was the approval from ComEd. I would definitely recommend it anyone who wants to go solar.

    This was a fast and easy experience. Erik and his team took the time to explain everything to us. The people working on the inside and outside of our home were friendly and professional. We're looking forward to the tremendous savings on our electric bill!

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 reviewers keep mentioning

  • team 2

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.

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.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • 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.
