The Verdict

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.

Reviews That Shaped Our Verdict

Paul C.
YelpOct 31, 2015

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.

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

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
