SunSystem Technology reviews

The Verdict
This company will leave you stranded. We found dozens of stories that follow the same grim pattern: breakdowns happen, you report them, and then you simply cannot get anyone on the phone. In one case, a customer's entire solar system was destroyed by wind in January 2021, yet the company kept billing them for equipment that no longer existed and ignored months of calls, emails, and even attorney letters. Another homeowner paid upfront to schedule a repair, watched their inverter fail within 30 minutes of a tech visit, then spent weeks chasing updates on a replacement that finally arrived unannounced while they happened to be home. We counted 32 reviews describing this unresponsive pattern, and only three reviewers managed to escape it by working with one of two helpful employees named by name. The rest describe vanishing after the sale, missed appointments with no warning, and repair timelines that stretch from weeks into months. If you need panels removed for roof work, expect them to lean against your house uncovered for four months while reinstall dates get canceled twice. One reviewer summed it up plainly: it is as though they do not even exist.
If you are comparing installers and this company quotes you, keep looking. The pattern is too consistent to ignore: once the system is on your roof, getting anyone to pick up the phone becomes nearly impossible.
Reviews That Shaped Our Verdict
Maddy V. moved into a home in November that needed a full roof replacement, so the leased solar array had to come down. SunSystem hired Novasource Power Services to remove the panels on January 12; the crew took them off and left the modules leaning against the side of the house uncovered. What followed was a string of delays — it took more than a month to get a reinstall date that was supposed to be in March, the company canceled that slot twice, and the job is now tentatively pushed to the end of June. She spent weeks calling and leaving messages that went unanswered and only recently managed to reach a case manager. Four months after removal, the system remains unfinished and the timeline keeps slipping, leaving the homeowner with canceled appointments and little communication.
Michelle M. has wrestled with a troubled solar installation since 2017 and watched the situation collapse after a wind event destroyed the entire system on Jan. 16, 2021. She ended up paying more than $25,000 over the life of the problems while the company continued to bill for a system that wasn’t functioning and even billed after the panel debris was removed from her property. She views the company as being in breach of contract: they refused to formally release her from the agreement or remove a lien of more than $50,000 on her home. On Sept. 23, 2021, Jared Wilson gave a verbal release, but no written or recorded release followed. Phone calls, emails, written notices and even attorney letters went unanswered, leaving her with what she describes as major fraud and the sense that the company had disappeared. She also calls out Corinthian and Nova Source Power as being involved with the same issues. The detail that lingers most is the unresolved lien topping $50,000 and only a verbal promise — no paperwork, no follow-through.
Shannon S hired the company to sort out a residential solar outage — mainly a modem and an inverter — after her inverter had been down for nine months. She discovered they were eager to send a payment link (they require payment to schedule service) but slow to do anything after that. A replacement modem took a long time to arrive — she accepted a supply‑chain excuse — and when a tech finally fitted it into the supposedly working inverter, the system failed within 30 minutes. Technicians then decided a new inverter was required, and weeks of calling, texting and emailing yielded little progress until the replacement was delivered to her house; she only caught the install because she happened to be home when a tech unexpectedly turned up. Even after that inverter went in the array still didn’t function and installers concluded another modem was needed. Most recently she had a same‑day window for a modem swap, waited past 3 p.m., got a delayed callback and then a cancellation text saying the tech had run out of time. She walked away from the ordeal frustrated enough to file a BBB complaint; the striking detail for prospective buyers is how quickly the company takes payment to schedule

What You Can Expect
Nancy B. moved into a new home with a SunPower solar system and then waited nearly 90 days to discover it wasn't operating properly. She had been loyal to SunPower for almost six years and expected smoother support, but customer service kept handing her incorrect information while the panels stayed offline. Ultimately technicians Billie from SONRAY and Matt from SUNSYSTEM Technology tracked down the problem and got the array up and running; she highlights their professionalism and sense of humor as what turned a frustrating situation around. She now has a functioning system and is awaiting SunPower to make good on the electric-bill adjustments tied to the outage.
Sally’s standout moment came when Joshua Kozub of Sunsystem Technology didn’t just arrange service visits—he took responsibility for filing the Solaredge warranty claims for their inverter and cell kit. She watched him move quickly to schedule appointments, patiently address their concerns, and handle the paperwork that often trips people up. The work felt organized and low‑stress throughout, and she walked away grateful that Joshua’s professionalism and extra effort cleared the most tedious part of the job: getting the Solaredge warranties claimed on their behalf.
Ralph P. ended up with what he calls an overpriced residential solar system that isn’t producing enough energy for his house. He expected the 25‑year parts-and-labor coverage he was promised, but when output wasn’t at 100% the company sent a technician who concluded the moderator needed replacing. The crew then asked for $250 for that replacement, a charge he found unfair because the visit didn’t fix the underlying problem. After switching his home Wi‑Fi to save money, reconnecting the moderator to the new network turned into a major headache, and the company didn’t get the system back to full production. The most striking detail: despite being told long-term coverage was included, he faced an out-of-pocket $250 demand while his array still underperforms.
