The Verdict

Marcor Solar will fix what other installers won't touch. We analyzed dozens of reviews and found a pattern that sets this company apart: they routinely solve problems left behind by competitors, often in a single visit. One homeowner had non-working panels for three years after multiple failed service calls from other providers until Marcor diagnosed the issue, ordered parts, and completed repairs within a month. We found 22 mentions of workmanship quality with only one complaint, and 15 reviewers praised post-sale support without a single negative comment. The installation crews are unusually clean and communicative, with one reviewer noting that a technician fixed an extra issue not even on the work order. (He also patiently answered "a ton of questions," which suggests either genuine helpfulness or the patience of a saint.) One homeowner reported that a 49-panel Long Island system produced more electricity than forecast a full year later, cutting bills to almost nothing.

If you want an installer who'll show up when your panels stop working and actually fix them instead of talking you through it over the phone, Marcor is worth calling. They cost more than some competitors, but reviews show they handle service issues other companies dodge.

3 Stories That Stood Out

1. Nicole LaMontagne
Google | Jan 6, 2025 |

Nicole had lived with solar panels that weren’t working for three years and had already endured multiple service visits from other companies. When Marcor took over the project, their team diagnosed the problem on a single visit, ordered the necessary parts, and finished the repairs within a month — a night-and-day turnaround compared with her prior experience. Carrie Cappello acted as her point person, proactively keeping Nicole informed about timelines and making sure each step moved promptly. She ended up with fully functional panels and the reliable communication that had been missing for years. For homeowners whose systems have lingered unrepaired or bounced between technicians, Marcor demonstrated that a single, well-managed visit plus consistent follow-up can restore service in weeks.

2. Billy Robitsek
Google | Feb 24, 2022 |

Billy called the second company after the first installer wouldn’t come back and tried to troubleshoot his malfunctioning rooftop solar system over the phone. The technician arrived, stayed patient as he fired off a ton of questions, and methodically brought the panels back to working order. Beyond the scheduled repairs, the tech diagnosed and fixed an additional problem that hadn’t been on the work order. Compared with the original crew’s phone-only approach, this visit felt thorough and attentive. The detail that sticks: the technician’s professionalism and willingness to answer every question while resolving an unexpected issue on the spot.

3. Gregory Haufe
Google | Feb 8, 2022 |

Gregory Haufe hired Marcor Solar to replace his roof and install a large, 49-panel solar array on his Long Island home, and a year later he couldn’t be happier with how it turned out. He watched the crews leave a clean, flawless roof and a neatly installed array — the workmanship stood out. The most striking result came over the first twelve months: the system produced more energy than projected and pushed his electric bills down to almost nothing. He encourages anyone weighing a similar project to contact Marcor — for him, the combination of impeccable installation and better-than-expected output is the detail that made the investment worth it.

Adam Postel hired the company to handle both a new solar installation and a roof replacement on his home, and he valued that a single team managed the entire project. He experienced excellent service and high-quality workmanship throughout the job. With one company coordinating the work, scheduling stayed straightforward and the handoff between roofers and solar installers never became an issue. He ended up with a completed roof and functioning solar array overseen from start to finish by the same crew.

3. Brian Allmendinger
Google | Nov 25, 2022 |

Brian and his wife hired Marcor to take down their existing solar array, design a new system for their renovated home, and reinstall everything on a brand-new roof. He found the whole process remarkably easy: Marcor handled removal, redesign, and reinstallation without drama, and the crew stayed professional and helpful throughout. The detail that stuck with him was how smoothly the company managed the entire transition during a major renovation — the solar work barely disrupted the project.

2. Carli Allmendinger
Google | Nov 25, 2022 |

Carli Allmendinger and her husband undertook major construction on their home that meant removing their existing solar array, redesigning the layout to suit a new roof, and reinstalling the system once the roofing was finished. She discovered Marcor Solar managed every step with minimal fuss — coordinating the removal, creating a new design for the updated roof, and putting the panels back up after the roofers completed their work. Marcor stayed professional and efficient throughout the project, and the most memorable part was how seamless the transition between construction and solar work felt, with the system handled on schedule and with little disruption to the household.
