This company is not worth the risk. We analyzed dozens of reviews and found a clear pattern of sloppy installations followed by complete radio silence when things go wrong. One homeowner called seven times over several weeks to fix a leak in their two-year-old system and never heard back. Another watched their panels slide off the roof due to poor racking, then left message after message with no response. Before you sign, the sales team is attentive and competitive on price. After installation, the customer service vanishes. Twenty-three reviews mention post-sale support problems, most describing leaks, wiring issues, or failed components that the company simply won't address despite active warranties. We found 20 complaints about value (often citing repair fees on systems supposedly covered) and 13 complaints about workmanship. If you need a company that will actually show up when your roof starts leaking two years in, keep looking.
If you're shopping on price alone, their quotes may look appealing. But when your system leaks or fails and you can't get anyone to return your calls, that discount won't feel like a bargain.
Patti R. had a rooftop solar system put in a few years ago and recently discovered it was leaking. Starting in early May 2022, she called the company seven times to arrange a repair appointment and received no response. The system carries a 12-year warranty, but she found the warranty effectively meaningless when nobody answered repair requests. She ended up frustrated and out of options after repeated unanswered calls, a detail that undercut the value of the warranty for her.
Donna L. received attentive, helpful service while buying and having a residential solar system installed, but two years later a water leak exposed a very different side of the company. When the leak started she spent about three weeks calling almost every day; the installer kept promising callbacks, yet nobody ever returned her calls. With no response and the problem unresolved, she ultimately hired a local contractor and paid out of pocket to repair the leak. The standout detail: strong pre‑sale support, but effectively no post‑installation customer service—after three weeks of unanswered calls she had to fix the issue herself.
Chuck W. ended up with panels that began to slide off his roof after a system was installed about seven years ago. About two years ago a company technician came out and discovered the rack had been poorly constructed — the workmanship left the mounting insecure. Over time the panels loosened and started to slip because of that shoddy construction. Chuck has left several messages over the past two weeks asking for help and has received no reply. The lasting picture: loose, shifting panels on the roof and unanswered calls from the installer.

Kim M. hired SunX to install a thermal solar system on her ranch-style roof about a year ago, and the job landed right in the middle of a company ownership change — a bit chaotic at first but ultimately completed well. She noticed the crew had placed too many panels on the north side of the roof; she called the new owners and they rearranged the array without argument. A year later two small problems cropped up — a minor leak and a faulty thermostat — and SunX sent technicians out promptly both times and fixed each issue. She measures a solar company by how it handles problems after the sale, and SunX met or exceeded that standard. Communication stayed clear through the process, pricing was competitive, and what lingered for her most was the company’s willingness to correct the roof layout and handle follow-up repairs quickly and without fuss.
Rita discovered a leak in her two-year-old pool solar system and blamed sloppy workmanship for the failure. She had counted on a contract that promised a 12-year warranty covering parts, panels, materials and installation labor, plus lifetime freeze protection — but the company’s response did not match that expectation. Instead, the installer wanted to charge a service fee just to come out and inspect the leak and planned to bill for any parts and repair labor. A service rep who was supposed to visit called in sick the day of the appointment, and the company left the reschedule open-ended rather than setting a firm return date, so she remains waiting for repairs. She called the experience the worst she’s had with a contractor and would not recommend SunX Solar Systems Inc., CA ROC Lic. #969780.
Jackie G. had a solar pool-heating system installed in 2018 and, years later, discovered the control panel would no longer activate the valve to run the heater. She phoned the company's office repeatedly and left messages but never received a callback. When she finally reached the salesperson, he told her he had quit and that the company wasn’t running well, leaving her with a nonfunctional system and no responsive support.
Stacy P. went into a solar project for her home and discovered Sun X stood out — they offered a competitive price and were the only company that brought up solar pool heating. She signed on, and the crew moved fast: work began quickly and wrapped up in just over a week. The installation included 25 solar panels, a solar pool-heating system, a variable-speed pool pump, and a Quiet Cool whole-house system. Inspectors came through and the system was switched on within a couple of days. The Sun X team proved professional, timely, and thorough at every step. What lingered as the clearest takeaway was the pool-heating option — something others hadn’t suggested — fully installed and delivering heat almost immediately once the system went live.

David G. decided to go solar for his home’s electricity but hit a snag when the national installer he started with wouldn’t touch his pool’s thermal heater. He called around and had SunX come out to move and replace the pool heating system; Pete arrived with a reasonable quote and used the site visit to walk him through electric system options and which setup would actually match his usage. David discovered the big-name company would have steered him toward a battery-heavy package that fit their sales model more than his needs, so he switched to SunX. SunX delivered a more efficient, better-suited solar electric system and shaved roughly $8,000 off the price. Kyle’s crew installed the pool heater and the solar electric system in four days, kept him updated throughout, and had the system producing his own electricity within 28 days of signing the contract. The detail that stuck with him: a routine pool-heater call turned into a tailored solar solution that saved thousands and got power flowing in under a month.

Tiffany R. hired Son Energy — which now operates as SunX Solar System, Inc. — to service her home’s solar tubes and later paid the company’s technician to install a small spa filter. Two years on, she discovered that the same technician, Jeremy Ybarra, had repaired her solar tubes under warranty during that visit but broke a water-valve lever while installing the filter and never returned to replace it. When she followed up, the woman who answered the phone back then, Samantha, refused to honor the original warranty, demanded $135 an hour to repair the broken solar tubes, and later insisted Jeremy no longer worked there. Tiffany also noticed the company changed names after a string of negative reviews and came away convinced the business hadn’t corrected its practices; she distrusts the many positive reviews and says the company challenged customers over negative feedback. The detail that stuck with her — an unrepaired water valve left after a paid installation and a warranty turned into a $135/hour bill — is the warning she wanted other buyers to remember.
Long-term satisfaction for Sun X Solar drops to 1.4 ★ compared to early reviews. This decline is worse than 68% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
