  Robert and his team are special mix of problem solvers, authenticity and honesty. Robert and his team completed a very large solar install for us last year with batteries , trenching , styles with Comed on our behalf and took the time to explain everything and work through every challenge. They coordinated with our roofers on a Davinici roof install which was complex . I had 7 companies quote me including Tesla solar, no one came close to the quality and value of the finished product Fibonacci solar provided. I have recommended others and continue to recommend Fibonacci and Robert !

  I was very impressed with the crew and the knowledge of the industry- very clean, very efficient, no corners cut whatsoever in the installation.

  Well, let me start by saying WOW WOW First off. Iam a blue collar worker (in the custom appliance trade) These fine young gentlemen did an incredible amount of work in two days. Which was impressive enough, but the quality Precision and excellence was wayyyy above Expectations. I am a hard person to work for due to my ocd. So for me to look at there work blu my mind.

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.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

• Licensed

  “under our belt our crew is fully licensed, trained, and dedicated to…”

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

• 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, LinkedIn, Facebook, X and TikTok. 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.

• —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.
