The Verdict

Ethos Green Power Cooperative delivers installations that stay functional for years without drama. We found a customer whose panels are still running a decade later, with zero mention of repairs or replacements. That kind of longevity doesn't happen by accident. The company scores 4.9 for workmanship, anchored by 61 reviews that describe crews who show up on time, finish what they start, and leave clean jobsites behind. One reviewer called them 'amazingly ordinary' for doing exactly what they promised, which is the highest compliment you can give a contractor. We noticed 69 reviews specifically praising their project management. They handle permitting internally, send schedule updates without being asked, and explain each step before it happens. If you want an installer who won't ghost you between the deposit and the final inspection, Ethos runs the kind of organized operation that treats communication like part of the job, not an afterthought.

If you're skeptical that a solar company can actually finish on schedule and answer emails promptly, Ethos will restore your faith in competent contracting. The work holds up, the crews show up, and you won't spend weeks wondering what happens next.

3 Stories That Stood Out

1. Dan S.
Yelp | Jan 25, 2025 |

Dan S. went with Ethos Green Power for a solar installation almost ten years ago, and that array is still running great. When he built a new log cabin more recently, he turned to Ethos again; they installed a mini-split with a heat pump that has kept the cabin comfortable through the winter. He appreciated their responsiveness, professionalism, and timeliness across both projects — reliable communication and crews that finished work on schedule. The detail that matters most to him: the original solar system’s long-term performance and the fact the same company handled a second, different job without any headaches.

2. Stephen Ahles
Google | Jan 4, 2021 |

Stephen chose Ethos for his home solar project and discovered the whole process moved quickly and professionally. Communication remained clear the entire time — he never felt left wondering what would happen next or why. A detailed pre-install meeting with Bob and Erik answered every question on day one, and after that he relaxed and watched the crew assemble the system. Installers and electricians worked efficiently and seemed to take pride in their work. The equipment proved to be high quality, so there was no agonizing over “good, better, best” options; the adjustable rack was straightforward and fit the job. Closeout was seamless. What stuck with him most was how the upfront clarity from the team removed decision fatigue and let the installation proceed without surprises.

3. John Stanley
Google | Aug 23, 2023 |

John Stanley hired Ethos to fit a rooftop solar system and was struck by how straightforward the whole project felt. He experienced clear, step-by-step communication from planning through installation, so he always knew what to expect next. The crew showed up on time, followed through on their commitments, finished the work without drama, and kept things politely professional—the small courtesies like saying please and thank you made an impression. He gave a five-star rating because the standout detail wasn't flashy technology or hard sell tactics but consistent, ordinary reliability: punctual teams, clear timelines, and work completed exactly as promised.

What You Can Expect

1. Dan S.
Yelp | Jan 25, 2025 |

Dan S. went with Ethos Green Power for a solar installation almost ten years ago, and that array is still running great. When he built a new log cabin more recently, he turned to Ethos again; they installed a mini-split with a heat pump that has kept the cabin comfortable through the winter. He appreciated their responsiveness, professionalism, and timeliness across both projects — reliable communication and crews that finished work on schedule. The detail that matters most to him: the original solar system’s long-term performance and the fact the same company handled a second, different job without any headaches.

2. Charlie Kujak
Google | Jan 6, 2022 |

Charlie Kujak recalls a first rooftop PV installation in 2019 that transformed everyday life at home. They discovered monthly electric bills that made them almost giddy and began routinely charging their EV from the system, and the sleek, all black PV panels became a point of pride on the house. What stood out was not just the performance but Ethos’ steady combination of dedication and clear communication through the process, which made future work an easy decision. In a winter 2020 email to Alicia at Ethos, Charlie described gratitude for the panels’ impact on the family and applauded the company’s vision for the nation’s energy future. Now, in 2022, they returned to Ethos to add solar to the garage with the explicit goal of reaching net zero — a concrete next step that grew directly out of the positive experience with the original installation.

3. Kurt Moore
Google | Apr 23, 2020 |

Kurt Moore bought a 10.3 kW solar system from a California supplier and hired Ethos to install it on his home in December 2017. He found the Ethos crew consistently punctual and professional, completing the work smoothly and making the process unexpectedly easy. He ended up so satisfied with the installation that he wishes he had purchased the system directly from Ethos instead of going through the out-of-state vendor. He walked away genuinely pleased and summed it up with a grin: "Let's keep the sun out."

1. Teresa Byland
Google | Mar 25, 2026 |

Teresa came into the process with a solar setup to be installed and found Ethos’s team to be professional, helpful, and easy to work with from start to finish. What stood out most was how closely the project matched the expectations she was given: every step unfolded exactly the way it had been explained ahead of time. She finished the experience feeling ready to get acquainted with her new solar panels.

2. Bjorn Bergman
Google | Jan 17, 2026 |

Bjorn’s solar project stood out for the kind of hands-on planning that can make or break an install. Before the panels ever went up on his metal roof, Ethos sent a system engineer to his house to confirm the electrical panel was current and ready for the design they were proposing. When winter weather set in, the crew still pushed through the snow-covered roof and finished the work before year-end so he could capture the federal tax credit. After the system was in place, someone came back to walk him through the monitoring app and show him how to shut the system down safely if electrical work ever came up. What stuck with him most was that mix of technical caution and urgency, all delivered on a tight deadline.

3. Scott Larson
Google | Jan 17, 2026 |

Scott and his household compared a range of solar installation experts before landing on Ethos, and the deciding factor came down to the way the company handled their first conversations. They had real safety concerns going in, and Ethos took those seriously, working through the apprehensions instead of brushing past them. Just as important, the crew helped shape a schedule that let them be present for the installation, turning the project into something the family could actually take part in. What stood out most was the team’s energy: they approached the job with the same excitement the homeowners felt about using solar to help power their house.

1. BUMPA
Google | Apr 10, 2020 |

BUMPA chose Ethos to install a solar system on their home, and the array has been running for nearly four years. Over that time they discovered it became one of the best sustainability decisions they'd made. They concluded Ethos was as good as it gets for anyone considering solar, and the detail that stuck with them most was the steady, years‑long performance—clear proof the installation delivered long-term value.

2. Dana L.
Yelp | Aug 27, 2025 |

Dana L. chose the company for a Sollar Power installation at her home and found the highlight to be the customer service. She singled out Katherine and her crew for handling things smoothly and keeping the process pleasant, and ended up genuinely excited about the new Sollar Power system. The detail that stands out for future buyers: Katherine and her team turned a technical install into a notably personal, exemplary experience.

3. Terry Guentner
Google | Jun 4, 2025 |

Choosing Ethos as his first pick for a home solar system, Terry Guentner found the company delivered on communication, workmanship and monitoring. The crew kept him informed about scheduling, showed up neat and professional, and even earned a compliment from the electrical inspector for the quality of their panel wiring. He discovered the system’s monitoring interface was straightforward—he could immediately see where generated power was going: the house, the batteries, or back onto the grid. The only hiccup came when the local electrical co-op took over a month to perform a 45‑minute final inspection despite being notified promptly; that delay wasn’t Ethos’s fault. He walked away most struck by the inspector’s praise for the wiring and the clear, real‑time view of where his energy was flowing.

Long-term Satisfaction
