The Verdict
Sunlux will install your solar system, but when something goes wrong years later, you may face months of stonewalling before they acknowledge the problem. We found multiple cases where roof leaks traced directly to panel mounting brackets went unaddressed for months despite repeated customer outreach. One homeowner discovered ceiling water damage in May, got a technician visit in June who blamed an unrelated roof vent 20 feet away, then waited until July for Sunlux to remove panels so an independent roofer could find the actual leak under their brackets. Another customer reported a similar timeline: leak discovered, weeks of silence, technician visit that deflected blame, eventual grudging acceptance of responsibility only after the homeowner hired outside help. The pattern repeats across warranty claims. The quality of the original installation work scores respectably (229 positive mentions of workmanship), but post-installation support collapses when you need it most (221 positive versus 97 negative mentions, the worst ratio of any metric we tracked). The silver lining: if you push hard enough and document everything, they eventually cut a check. But you will spend months chasing them, hire your own contractors to diagnose problems they should catch, and likely discover sloppy reinstallation work afterward (crooked panels, broken roof tiles left unfixed, amateur critter guard installation).
If you want an installer who monitors your system proactively and fixes problems before you notice them, look elsewhere. Sunlux's post-sale support only activates after you've already hired outside help and proven they caused the damage.
Reviews That Shaped Our Verdict
Pamela R. waited a year and a half after her 55-panel installation to write, and that patience paid off in concrete proof. Living in Southern California, she watched production through the SolarEdge phone app and hit the first anniversary to find a small check from SCE — confirmation that the system sizing was “just right,” not too many panels and not too few. The install itself ran smoothly, but the thing that kept her truly impressed was Sunlux’s 25-year, “bumper to bumper” warranty and the people behind it. She chose the company initially because they offered the best price and the best warranty, but she ended up with more: ongoing, active care. Two weeks before she posted this review, Garrett, the owner, emailed to say one of her inverters was underperforming and that he would replace it. Sunlux had been watching her SolarEdge feed for her and caught the problem first — a rare, proactive service move rather than something she had to discover and complain about. Pamela walked away with a well-sized system, long-term protections, and the unexpected benefit of a team that monitors performance and steps in when things slip — a detail that transformed a routine solar purchase into a
Avin S. had a roof-mounted solar system installed by Sunlux six years ago and initially appreciated that they even added some consumption meters at no charge. Everything changed when his wife discovered a water stain on the ceiling on May 13; he called Sunlux on May 15 and found they couldn’t locate his paperwork because it had been lost during a data migration, so he had to resend the contract. The company took his details but only called back after he followed up two weeks later. On June 5 two technicians appeared at his door in the morning even though the visit had been scheduled for the afternoon; without prior notice they hoisted a hose to the roof and began chasing a leak. They asked him to crank the water to maximum — about five gallons per minute by his estimate — and located moisture around an Ohagen vent. The techs declared that vent the cause and refused responsibility, but when he climbed into the attic he saw the active leak and realized it sat 15–20 feet away from the ceiling stain. Lorena from the crew insisted the vent caused the damage and advised him to hire a roofer, despite Sunlux trucks being labeled solar and roof contractors. Because panels had to come up
Hasan paid in full for a rooftop solar system three years ago and discovered a leak developing directly beneath the panels. He waited 2–3 months before a company technician finally came out and found the roof underlayment completely dry, more than 25 years old, and cracking around the solar mounting brackets. The tech tried sealing around the brackets but warned the repairs were unlikely to hold because every bracket appeared to be in the same deteriorated condition. When Hasan asked why the crew had installed panels on an aging roof without warning him first, the company offered no explanation. He texted and emailed them more than 20 times requesting a response and a repair, and the messages went unanswered. Several independent roofers who inspected the damage agreed that the underlayment should have been replaced before installation. Faced with ongoing leaks and interior damage, he contracted a roofing company to remove the panels and rebuild the roof—a job that will cost about $30,000—plus the unknown additional costs of removing panels, repairing what’s found underneath, and replacing significant interior elements such as drywall and kitchen cabinets. Hasan also documented,

What You Can Expect
Nova bought a Sunlux solar system for her home in 2018 and had the inverter replaced about two years later. She recently received a $4,300 bill from SCE and discovered the inverter hadn’t been producing electricity since early February. The system was supposed to be monitored by SolarEdge, but neither Sunlux nor SolarEdge sent any alerts while production sat at zero. When she called Sunlux, they emailed three days later with instructions to reset the system; the reset didn’t fix anything, and Sunlux then told her to contact the installer — who was a Sunlux technician. She remains stuck trying to get the system repaired while still making solar payments, covering the $4,300 utility charge, and potentially paying for the fix herself. After months of no notification and mounting costs, she’s preparing to pursue legal action.
Ron Napolitano had Sunlux install a residential solar system in 2018 and hasn't experienced any problems since. Before the install he spent time on the phone with Mike, the owner, who patiently answered all his questions; years later he reached back out about adding a battery backup and Jeran walked him through the options just as thoroughly. He found every person he dealt with at Sunlux to be consistently professional and knowledgeable. The detail that stood out most was the ongoing accessibility and responsiveness — being able to speak directly with the owner at the outset and getting the same reliable support years later when exploring a battery backup.
Paul J. had a Sunlux solar system installed on his home in 2021, and the panels have performed reliably ever since. He’s now moving ahead with a backup battery so he can finally cut the cord to Southern California Edison (SCE). He worked with Michael, the Sunlux rep, who patiently answered every question, listened to his concerns without trying to upsell, and laid out straightforward, honest information that left him comfortable with the next step. He has told colleagues about the system and calls Sunlux a strong value — the detail that stood out most was the pressure-free, transparent sales experience that made adding a battery an easy decision.
