The Verdict
Solar Tuneup is the rescuer you call when your original installer vanishes and your panels stop working. We analyzed reviews spanning multiple years and found the same story over and over: people discover their installer went out of business, panic when they realize nobody will touch their system, then find Justin. In one case, a homeowner's inverter died and Justin not only diagnosed it but walked the warranty claim through the manufacturer and came back weeks later to install the replacement part himself. The pattern that stood out most was his refusal to upsell. 48 reviewers mentioned fair pricing with zero complaints about inflated quotes, and we found multiple stories of him walking customers away from expensive projects that didn't make sense for their situation (he returned one customer's deposit after determining their house layout would make battery installation prohibitively complex). The second distinctive strength is follow-through on orphaned systems. 73 reviewers praised his diagnostic skill, often mentioning he'd repaired systems 8 to 11 years old that other companies refused to touch. He provides before-and-after photos of cleanings, walks roofs before jobs to plan logistics, and registers replacement parts with monitoring platforms so warranty coverage continues. One reviewer joked that if Justin could walk on water it wouldn't surprise them, which feels about right given he revived a six-month-dead Sunpower system in a single day.
If you need someone to fix, maintain, or resurrect a solar system and your original installer is unreachable or out of business, Solar Tuneup is your best option. Justin won't try to sell you a new roof when your panels just need cleaning.
3 Stories That Stood Out
This homeowner first met Justin in 2021 when several Enphase panels went offline on a ranch-style property. Justin turned up, quickly diagnosed faulty inverters and got the system running again — and what stuck with them was not just his technical know-how but how straightforward and honest he was, a sharp contrast to previous encounters where other installers pushed bigger, unnecessary jobs like roof replacements to pad the bill. In 2025 they called him back to explore adding batteries. Justin walked the property, patiently explained options without pressure, and spent many hours on his own dime answering texts, emails and researching possible solutions. Together they discovered the house layout created complications that would make a battery retrofit more expensive and awkward than the original idea. Rather than push the sale, they mutually decided to drop the project; Justin immediately returned the deposit and stayed friendly throughout. The detail that lingers is simple: he invested unpaid time to be helpful and then promptly refunded money when the job didn’t make sense — a rare combination of technical skill and customer-first honesty.
Kim T. discovered her solar array had stopped producing power when her electricity bill arrived much higher than expected. She tried to contact the original installers only to learn they were out of business, so she searched Yelp and found Solar Tuneup. She reached Justin, who answered quickly, scheduled an inspection, and afterward walked her through his findings in straightforward language: the inverter was dead. He called the manufacturer, ordered a replacement, tracked the part over the following weeks, then came back to install it. Prices felt reasonable compared with other options, but what set the experience apart was Justin’s follow-through — clear explanations, proactive coordination with the manufacturer, and returning to finish the job.
Alice discovered one of the microinverters on her rooftop system — originally installed by GCI Solar in 2014 — had failed after about 11 years, leaving one panel with no output for months. She confirmed through Enphase monitoring (the phone app and web portal) and received a replacement microinverter from Enphase under warranty. Faced with needing an installer, she first waited over three weeks for a pricey estimate from another company, then reached out to Justin at Solar Tuneup in Orange, CA. Justin recognized GCI’s original work, offered to both install the new microinverter and clean the array, and promised to register the replacement with Enphase so the correct serial would appear in her monitoring. He scheduled the job for the next Monday, arrived with Apollo that morning, and completed the install and panel cleaning with clear communication, professionalism, and a reasonable charge. The panels came away clean, the previously dead panel began producing again, and the monitoring showed the new unit properly registered — the detail that really set the job apart was Justin handling the Enphase registration so the system’s monitoring stayed seamless.

Daniel called Solar Tune-Up for a routine check of his home’s solar panels and got an immediate quote from Justin. He watched Justin arrive on time, handle the job efficiently, and finish without fuss. That promptness and straightforward service convinced him to make Solar Tune-Up the only company he’ll let touch his panels from now on.
Robert Varo has relied on Justin for solar work at his home for seven years, repeatedly calling him back rather than looking elsewhere. He watched Justin arrive on time, treat each visit with courtesy and professionalism, and complete projects with consistently noticeable quality. Over that stretch the relationship felt dependable—more like a trusted craftsman than a one-off contractor. The detail that kept him coming back was simple but rare: punctual, professional service paired with first-rate workmanship.
Daniel R. emailed Justin about an inverter problem and got an immediate reply. He booked a time for Justin to come to his house; Justin arrived on schedule, handled the repairs and stayed to confirm the inverter was working properly. He recommended Justin to a friend right away and plans to call him exclusively for any future solar-panel work.
Chafic found Justin and his crew to be top-notch—easygoing, reliable, and refreshingly honest in an industry where trustworthy contractors are hard to come by. When his home went through a roof remodel, Justin took on the tricky task of removing the solar array and reinstalling it afterward. He walked away impressed by the crew’s workmanship and candor; they handled the panel removal and reinstallation with clear competence. The memorable detail for anyone considering this company: you get an honest, low-drama team that can manage a solar move during roofing work and deliver excellent results.
Jeanne found herself with a home solar system in need of repairs about 8–9 years ago after the original installer closed, and she had nowhere to turn. Justin stepped in, willing to help and bringing the practical knowledge required to get the system back on track. She kept relying on him for follow-ups and fixes, and eight years later he remains her "go to guy." What stuck with her was that he didn’t walk away when the original company folded — he stayed available and reliable over the long haul.
Donna called them when her solar system started acting up, and Justin came out and worked through the problem thoroughly. He diagnosed a broken inverter, confirmed it was still covered by warranty, and took care of the necessary repair logistics so the issue was resolved smoothly. The memorable part of the visit was his careful troubleshooting combined with straightforward warranty handling — the whole situation was wrapped up without fuss.
Andrew had Justin come out to diagnose a problem with his solar panels and found the whole process smooth and straightforward. Justin was easy to book and showed up on time.
