Full Spectrum Solar

Each mark is one company we hold in the Milwaukee area whose Google breakdown has been read, placed by its share of one and two star reviews. Full Spectrum Solar is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

  Exceptional service, communication. Have a new roof and roofer inspected the installed solar and said they did a much better job installing than many companies do. Highly recommend.

  The team at Full Spectrum did a fantastic job of helping us navigate through the process of getting solar at our house. Greg took the time to explain things in a way we could understand. The install team was efficient and cleaned up both outside and inside. We are very happy we went with Full Spectrum and highly recommend them if you want to add solar to your property.

  We are thrilled with our new solar installment! Everything was well explained, and all work was completed according to the timeline and with exceptional professionalism. Our project manager, Greg, knows his stuff and did a fantastic job of communicating and organizing. Installers and electricians were terrific, too. We highly recommend this company!

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.

• Family owned

  “Contractor" Full Spectrum Solar is a family owned and operated business that has been…”

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

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

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.

• —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.
