Modern Mill Solar reviews

This homeowner had a solar system installed in 2019 but ran into long-standing gaps in local office support. When a problem appeared this summer, calls to the local office went unanswered and they even had to contact the company’s Illinois office before remembering a direct contact they had saved. They reached out to Tyler, and that contact changed the experience: he answered promptly, showed clear knowledge of the system, got their array back up and running, and kept them informed about what was happening. The installation crews themselves had always been reliable — from the original 2019 install to a couple of follow-up visits over the years, the technicians arrived friendly and knowledgeable. The five-star score hinges on that recent interaction with Tyler; having him as a dependable point of contact is the detail that stuck with them.

Ryan picked Modern Mill Solar for a residential install in July 2019 and discovered the biggest selling point was the financing: while local banks and credit unions were quoting unsecured loans at 7–9%, Modern Mill arranged a loan at 3.79%, which turned the system from a stretch into an affordable monthly payment. He ended up replacing his utility bills with that solar loan and now produces enough electricity to charge an electric vehicle, so the numbers that mattered to him really came together. He watched the project move quickly too — quote to finished install in under two months, despite 2019 being a frantic year for solar as homeowners rushed to capture the final year of the 30% federal tax credit. Modern Mill handled the permits and utility interactions, and they’d already come to the house before the sale to assess roof orientation, understand energy goals, and present design options that fit his needs. What stood out after the install was their service. Modern Mill set up remote monitoring on the array, which paid off when the SolarEdge inverter’s communications card failed about eight months later; the company spotted the fault remotely, came back on-site, and repaired

comettug1 had solar panels installed on their home in 2022 and expected the deal to include promised rebates and several home-improvement upgrades. The company repeatedly pledged those extras but never followed through, and every attempt to contact them afterward went unanswered. In the end they were left with the installed system but without the promised rebates or upgrades and no way to get a resolution.

L. J. Boniface started out impressed: the installation looked clean and the technicians seemed to do a solid job on the roof. About a year after activation, though, they discovered system output had fallen by roughly 50 percent. Repeated attempts to get an explanation from Modern Mill went nowhere—no returned calls and no troubleshooting from the company—and yet they remain on the hook for payments for a system that isn’t delivering as promised. The lasting image: well-installed panels producing only half the expected energy and no communication from the installer.

Ryan P reached back out to Modern Mill years after his original rooftop system went in when it needed servicing. Their tech, Josue, quickly tracked down the required changes and completed the fixes — even though he handled the job solo, he stayed engaged and never made the visit feel like an inconvenience. The work stretched over more than a day; to wrap things up the following morning Josue actually stayed at a nearby hotel so he could finish without rushing. It took two calls to the office to lock in the appointment, so he learned to be patient: Modern Mill won’t rush jobs, but they do stand behind their installations long after the initial install. The detail that lingered was simple and concrete — a lone technician who stayed overnight to make sure the job was done right.

Brenda Hantz hired Modern Mill to install two rooftop solar arrays and an add-on generator more than two years ago, and the project never settled into a reliable system. She ended up with only one of the two arrays functioning because the other keeps tripping the breaker, and attempts to get a technician out have gone unanswered for months. The generator was meant to include a WiFi chip so she could monitor it from a phone app, but that feature was never enabled and remains unaddressed. The installation itself dragged on—took over six months to become operational—and the crew struck her as inexperienced: they admitted they hadn’t installed that many residential panels before, spent time standing around or on their phones, and frequently seemed unsure how to proceed. Follow-up communication broke down entirely; she’s been waiting months for service and has even heard the company may have shut down. What lingers from her experience is not a single failed part but the combination of a half-working system and persistent silence from the company after installation.

Tara Baals put solar on her home just over a year ago and has enjoyed noticeably lower electric bills while feeling good about the environmental benefits. She found the paperwork quick and painless, and the installation itself went smoothly. A year in, she still credits the fast, hassle-free onboarding and trouble-free install as what made the whole upgrade so easy to live with.

Andy Mattson ended up with a solar system that has been operating for two years, and then discovered the company was out of business — all phone lines went dead, both locally and at the parent firm. The parent company in Indiana told the BBB it was closing and then stopped responding to BBB inquiries. While the company was still active, he experienced a chaotic operation: routine logistics and required post-installation inspections and verifications never happened, calls produced the runaround, promised callbacks never materialized, and staff eventually began dodging his number. Because those post-inspection steps were never finished, his system has been running without the final sign-off for about two years. He also noticed an apparent “owner” reply to a review a month ago even though the business has vanished, and he suspects that response was aimed at delaying legal claims while bankruptcy matters are sorted. The enduring detail that will stick: the system stayed energized without completed post-inspection follow-up for two years, and the company disappeared, leaving no reliable way to get the required approvals or support.

Liddie purchased a solar system in December 2021 and expected the usual post-installation follow-up and rebates. She turned on the system and the company promised a rebate check 60 days after the panels started producing power. Instead, she watched the weeks roll into months: after four months she still hadn’t received the check. Every time she reached out the phone went to voicemail; on the rare occasions someone picked up they pledged to call back but never did. The bottom line: months after installation she’s left waiting for a promised rebate and getting only unanswered calls and broken promises.
