Arch Solar Review

Arch Solar reviews: what customers say

Each review site shows its own score; we read them on October 12 and 13, 2026 and do not combine them or add our own rating.

• Google4.6 / 564 reviews · Plymouth, WI office listing only, not company-wideRead reviews

The five positive reviews below praise responsive staff, smooth utility coordination and professional crews, including one install after heavy snow. The four negative reviews describe a system down for months while a part was unavailable, a $300 travel fee the reviewer says was not disclosed, a used inverter from the company that did not work, and a reviewer reporting $8,000 in extra fees and unreturned calls. These are issues to ask about, not a measure of how often they happen. Ask Arch what a service visit costs, including travel fees.

How we picked these: the five newest 5-star and the five newest 1- or 2-star reviews with written text on Google and Trustpilot, as of October 2026 (64 reviews read, back to Dec 7, 2018). We found no Trustpilot page for Arch Solar on October 12, 2026. Each quote is one sentence, word for word. Picking the highest and lowest ratings shows the range of experiences; it is not a representative sample, and we did not verify what reviewers describe.

How much does Arch Solar cost?

Arch publishes ballpark prices for three sample system sizes on its residential solar estimate page, but your price depends on your home. Ask for an itemized quote showing the cash price, system size, equipment models and, if you finance, the lender, APR, fees and financed total. Its FAQ says permit and interconnection fees are included in the project cost; confirm that in the quote. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.

Plans as listed in Arch’s residential FAQ, read October 13, 2026. No lease or PPA is listed.

Arch says most of its residential installs use microinverters, which come with panel-level monitoring (FAQ). Its energy storage page names Tesla Powerwall and FranklinWH batteries, and its service page mentions monitoring for Enphase, SolarEdge and Tesla systems. In an April 19, 2024 blog post, Arch said it leaned toward REC Alpha Pure and Silfab panels at the time; no current page names a panel brand. Your written proposal should list the exact panel, inverter and battery models, the system size in kilowatts (kW) and the forecast yearly production in kilowatt-hours (kWh).

What does Arch Solar’s warranty cover?

Company-published terms from Arch’s service and quality page and residential FAQ, read October 13, 2026. Your signed agreement decides what applies.

Where does Arch Solar operate, and which licenses were checked?

Arch’s about page says it serves all of Wisconsin from offices in Plymouth, Milwaukee and Madison, with a focus on Greater Milwaukee and southern Wisconsin. Its FAQ says it knows most municipalities in southeastern Wisconsin, and its residential page has city pages for Madison, Brookfield, Pewaukee, Grafton, Sheboygan and Waukesha (read October 13, 2026). Its quote form also refers to an Illinois service range without detail. A listed city does not mean every address qualifies or that EcoGen can connect you with Arch there.

Licenses

We have not checked Arch’s licenses in a state registry yet, and its website does not list license numbers we could match. Check the license yourself under the exact business name on your contract. A license check confirms registration, not workmanship quality.

Arch’s about page says its staff are licensed and NABCEP certified and that a founder became one of the first NABCEP board certified PV installation professionals in 2005. Its homepage also describes the company as veteran founded and woman owned. These are company statements; we did not verify them.
