Sumpter Solar Services reviews

Jared hired Sumpter for a home solar install and ended up with a 17-panel system that’s producing power. He appreciated a crew that stayed polite and professional throughout the process. The clearest takeaway: a straightforward, functioning 17-panel setup delivered by a courteous team.

DeWayne Gosox found himself with a stranded solar installation after his original installer went out of business, and Matt, Shelby and the rest of the team stepped in to rescue the system when other companies wouldn’t touch it. He watched them methodically diagnose the problem, explain what work and paperwork were required, and carry out the repairs and reconnects until the array was producing again. The crew kept him informed at every step and kept pushing until he felt completely satisfied — the standout detail was their willingness to take on a difficult handoff and see it through to full operation.

Donna found she'd struck gold when Matt Kadwell stepped in during installation — he was the only contractor who could get backup batteries for their solar system, and his knowledge and professional crew left a strong first impression. For a while the install felt promising. Two years after the install, she discovered the experience had soured. The backup batteries began malfunctioning; one battery proved faulty and was removed and returned to LG months ago, but no replacement arrived and Matt offered no alternative solutions. She lost power several times and learned the remaining batteries couldn't keep the house running. On one occasion wind knocked out the grid while the sun was bright, and the solar setup still failed to provide power. What started as a smooth, professional installation ended up plagued by glitches and a long, unresolved warranty hole — the pending LG replacement and lack of options from the contractor remained the most frustrating, lasting impression.

Deven had an existing rooftop solar array and, in late 2024, added a 15 kWh battery to the system. He found Sumpter’s service and communication excellent from start to finish, encountering team members who were consistently knowledgeable and friendly. The installation integrated smoothly with the existing array, and he walked away impressed by how well the staff could explain technical details and handle the upgrade. The clearest takeaway: the team's expertise and approachable communication made a potentially complex battery add‑on feel straightforward.

Deb Rife watched the crew push until her solar system was up and running. She appreciated their hard work and the patience they showed throughout the process. The lasting impression was their persistence in getting the system live — steady follow-through that made the difference.

Jim Johnston began a home solar project in November 2023 and ended up with the panels physically installed but no interconnection approval from Consumers Energy. He blames Sumpter Solar for supplying inaccurate paperwork, failing to follow up with the utility, and showing a general lack of concern that has left his application for interconnection at risk of cancellation. He grew more frustrated when owner Matt Kadwell texted that he needed a few days for a stress break, while required documents still hadn’t been completed and the deadline for the utility submission was closing in. He noticed Sumpter Solar’s public response that shifted blame to Consumers Energy, but the company never picked up the phone or sat down with him and his wife to resolve the issue. Emails went unanswered, communications were nearly non‑existent, and he watched the timeline for approving the interconnection shrink. Accountability, he found, was missing at key moments. What sticks from his experience is the combination of installed hardware with no approval to operate and an owner admitting to stepping back—leaving a live application in jeopardy just as the approval window was about to expire.

Alice hired the company to repair the rooftop solar panels that heat her backyard swimming pool. She found the crew both professional and personable; they diagnosed the issue carefully and delivered craftsmanship that went the extra mile to finish the job. She plans to call them back for ongoing maintenance of her solar system.

Matthew Soberal had installed a system from another company that later went out of business, leaving him with poor performance and growing frustration. Sumpter Solar sent a crew to inspect the entire setup, uncovered the faults in the system and repaired them on the spot. After their visit, his array began producing better than it ever had under the original installer. For the first time, he no longer feels solar was a "total waste of money." The detail that sticks is the technicians’ on-site diagnosis and immediate fixes — the single visit that turned a failing investment into a working system.

Tim Laskowski handed his system over to Sumpter Solar after the company he originally bought from went out of business. At first the crew acted fast: they showed up immediately and replaced numerous failing components, restoring parts of the system. The next interaction, however, unraveled. He explained how urgent the problem was—his furnace wasn’t working because the solar system had no output—and was promised a callback with a date and time for service. A technician left a voicemail the following day saying the service manager was tied up and would follow up soon. After repeated phone calls and texts, he heard nothing for ten days. The lingering impression: quick, effective repairs at first, then a total breakdown in follow-through during an urgent heating outage, leaving him without a scheduled return visit after ten days.
