Its one and two star share is level with the typical installer in Milwaukee. Across Wisconsin, 24 of the 58 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 93 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    My experience with Arch Solar involved issues with communication, contract adherence, and the handling of corrective work. The Solar Project Agreement required exterior conduit routing for both the home and garage. Arch Solar instead penetrated the garage roof and installed interior Romex wiring, which differed from the Statement of Work. A City of Milwaukee inspection for Permit ESPV‑25‑00111 failed on January 30, 2026. Arch Solar did not inform me of the failed inspection, the defects identified, or the need for corrective work, and no corrective work occurred for more than 38 days. I learne

    My system has been down for months. Terrible customer service. Haven't been getting my calls returned. I'm paying my loan payments every month plus my full energy bill. I will also have to pay for labor and parts when (if?) the part needed ever comes in. I'm ten years into my loan and have ten years left. Wish I could get out of it-- seems like a good idea to go solar at first-- they tell you it makes financial sense-- but turns into a bad idea when you're locked in and the system goes down for many months. Unless you're rich, be careful.

    The construction of the solar system went very well and safely: However the communication with the office was poor and communications went unanswered.

    16 solar solar panels were installed on our home roof, quickly and efficiently, years ago and are still working fine and unnoticed. It's so nice seeing a monthly electric bill that is significantly lower than a typical electric bill. Maybe two or three adjustments needed to be made over the years that were done without additional cost by the original installers, Arch Solar.

    Good product and installed well. It was nice having one company from start to finish. I would recommend.

    We had 16 panels installed by Arch. Could not be happier with the results

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.

  • Family owned

    “make a positive difference in a small family-owned organization. She goes on to say that…”

  • Years in business

    “NABCEP certified solar experts with over 100 years of combined experience. Our company…”

  • Licensed

    “and have a diverse staff of trusted, licensed, NABCEP certified solar experts with…”

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

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.
