Unisun Solar is not worth the risk. We analyzed dozens of reviews and found a company with a broken process and a trail of abandoned customers. One homeowner waited seven months for a system that still wasn't working, during which the financing company forged a signature and placed a lien on the house. Another paid loan installments for months before the system was even activated, then spent weeks trying to reach anyone who could help. The pattern is consistent: door-to-door salespeople promise fast timelines and smooth processes, but once you sign, communication collapses. Fourteen reviews mentioned failures in post-sale support, the worst signal in our data. Installation crews showed up unannounced, failed city inspections, and disappeared mid-job. When homeowners called for follow-up (like reinstalling three panels removed for permitting), they left four voicemails over weeks with zero callback. The financing arrangement deserves special attention. Multiple reviewers reported never seeing paperwork until a lien appeared, and a promised bill-difference rebate program simply never paid out despite repeated requests. If a company can't return a phone call during installation, they won't answer when your inverter fails in year three.
If you're considering Unisun, know that smooth sales pitches give way to months of delays, ignored calls, and unfinished work. The few positive reviews are from 2015-2016; the problems are current and systemic. Choose a company with a track record of answering the phone after the contract is signed.
When Lisa W. let a Unisun Solar representative into her ranch-style home, she listened to a friendly pitch; on his second visit he returned with his “boss” and they filled out tablet questions about the house and her PGE bill. By the third visit a 15-minute phone call had produced loan approval with no money down, and she expected panels on the roof within a month. Instead, seven months dragged by with nothing but promises. The first crew of three young men arrived and supposedly installed 29 panels in a day—only one of them actually did the work, the others looked busy and the job remained unfinished. Three weeks later two of the same crew came back to add the last five panels, then left to buy parts for the exterior electrical box and never returned or called. That pattern repeated: long gaps between visits, new people showing up with explanations that someone had quit or been fired, and no steady team to finish the job. The city inspection failed very poorly, and sporadic return visits did not resolve the issues. Then she received a letter: the lender associated with the project had placed a lien on her house and attached a contract she had never seen; the bank demanded roughly四
Paul C. bought a 27-panel solar system in February for a house he'd owned only about six months, then watched the project stretch out through 14 separate visits—some scheduled, some showing up unannounced—leaving his wife startled to find strangers in their backyard. By May the array was physically in place but Roseville Electric refused to approve the full system because there wasn’t enough prior energy-use history, so the utility demanded three panels be removed. Unisun removed those panels and promised to reinstall them after the family had lived in the house for a full year. By October, believing they’d met that requirement, he called four times to arrange the reinstallation; each call produced a promise of a callback that never happened. The company left three panels in their garage, repeatedly failed to follow up, and left his wife in tears on multiple occasions — they feel taken advantage of and still have no clear path to get the missing panels reinstalled.
James M. regrets hiring Unisun for his home solar installation: he ended up making loan payments before the system was even activated. He discovered the job failed inspection at least once and stretched several months past the original schedule. Getting anyone to follow through became a grind—he had to call repeatedly about simple issues and was often routed to an answering service because the office was short-staffed. The plumbing contractor he contracted through, Syntrol, wouldn’t discuss solar either and funneled him to that same answering service. He was promised enrollment in the “Savings start today” program, which would cover the difference between his PG&E bill and the loan payment, but that never materialized despite repeated assurances that a check was coming. After dozens of requests he finally received a generic packet from the coordinator, but was refused a signed warranty from Syntrol or Unisun unless he pushed for it. Bringing the system onto the monitoring platform proved difficult and it still doesn’t report properly—he suspects installation issues. After months of chasing paperwork, payments, and fixes, he worries about obtaining service down the road or whether a

Brodie had solar panels installed on his 14-year-old home last year and called the company after a recent storm produced a new roof leak. He got a service visit within two days; Jose Rodriguez traced the problem to a nail-driven hole left by the builder rather than the solar install, and Brodie verified the damage himself. Jose repaired the roof at no charge, ran a water test, and confirmed the leak stopped. Having experienced smooth sales and installation before, he found the most memorable part of the interaction was the company’s willingness to fix and prove the repair even when the issue wasn’t theirs.
Tina's new solar panels went up on her home today, and she and her husband found the entire process exceptionally smooth. They discovered a professional, organized crew—Jimmy walked them through each step in plain language, kept on top of the paperwork, confirmed the installation date, and came back to inspect the finished work to make sure it met their standards. Every phase happened on the timeline they were given, just as promised. The array hasn't been activated yet, but they're looking forward to lower bills—and the detail that stood out most was that the system required no out-of-pocket payment. If anything changes once the panels are live, she will update the review; for now she gives Unisun an A+.

Luie C. answered a knock from Omar, and from that first conversation through the day the system was switched on he walked away with a straightforward, pressure-free path to solar. Not knowing much about options, he got connected to Omar’s partner Darrell, who patiently walked him and his wife through purchase versus lease and explained why buying made more sense for their situation. Over several weeks they invited three other companies onto the property; each competitor pushed leases, while Unisun laid out purchase pricing without the usual upsell. After every outside meeting Luie ended up with more questions, and Darrell consistently picked up the phone, answered every question, and stayed patient throughout the process. They chose Unisun partly for that responsiveness and partly because the team created a genuine family-like atmosphere — Luie felt appreciated and confident that Unisun (also known as Syntrol) will be the first place he calls for other home projects. The experience closed with the system flipping on and one small, specific wish left: he wants his “I (heart) My Solar!” sign.

Brice B. went into the process with solid early impressions — the sales team showed up on time, stayed flexible, and made a good first impression. After that, he ran into a string of missteps: a follow-up representative arrived unannounced and left without any paperwork or a business card, and the installation crew failed to show for the first scheduled date, forcing a reschedule. When installers did return, they couldn’t finish because the engineering plans lacked clear directions, and the job then sat in limbo while he and his wife repeatedly called to get someone to look into it. He arranged to take time off work for a permit signoff only to find no company representative available to meet the inspector, and when the tech finally completed the wiring he used a garden hose draped on the house to secure the work. That required Brice to take another day off to get the permit finalized. To add to his frustration, an unrelated company representative later put a ladder over the fence and photographed the yard without prior notice or consent. He walked away frustrated and unwilling to recommend the company — the image that sticks with him is a half-finished job held up by a garden hose
After his Unisun Solar installation, Grant H. discovered he hadn’t been switched off PG&E and ended up paying the utility while his system remained inactive. Nick Cornett, Unisun’s VP of Sales & Finance, reached out and took ownership of the problem. By the end of the day Nick traced the issue, explained exactly how Grant could switch from PG&E, provided clear instructions, and arranged to rebate the payments Grant had made during the downtime. Grant found Nick pleasant and responsive, updated his Yelp entry to reflect the fix, and left a five-star rating. The detail that stands out: a senior executive personally resolved the switch and secured a rebate within hours, turning a frustrating onboarding problem into a quick, concrete solution.

Dave K. signed up for a residential solar system in July 2015 and expected a straightforward rollout, but the project turned into a drawn-out ordeal. He believes Unisun acted only as the installers while Sunnova handled the solar side; after signing he heard nothing until late October, finally got panels installed in November, and didn’t have power flowing from the system until February 2016. Installers told him turning the system on was as simple as flipping a few switches and handed the task to him — he flipped them and the array never came online. Sunnova ultimately sent a technician who discovered standing water inside the equipment box (an installation error), troubleshot the issue, and got the system working after about an hour. Throughout the process Dave watched promises slip, communications lag, and excuses pile up, and the company has not fully honored the financing claim that “savings start when you sign” or rebated the difference tied to the Unisun rate. He accepts some responsibility for not researching more thoroughly, but what sticks with him most is being told to power the system himself only to learn it had been left improperly installed and sat idle for months — a
