Claremont is not like other Inland Empire cities. The trees change everything. We know that before we even get on your roof, because we’ve been fixing solar on these streets long enough to know what a protected oak or a spreading jacaranda does to a panel array. This page is about what actually breaks, what it costs, and how we fix it here in 91711.
Why Gus’s Solar Is Claremont’s Preferred Solar Panel Repair Company
Gus Petrakis founded Gus’s Solar in 2011, and he still puts his own name on the estimate. When a Claremont homeowner calls with a dead inverter or a ground-fault alarm, they talk to a real person who knows the difference between a microinverter issue on a shaded east plane and a wiring fault caused by squirrels under a maple. That’s the kind of thing you only learn from years of local repair work, not from a call center script.
Our customers in Claremont keep calling us back because we show up when we say we will. We answer calls live, 24/7. If your production monitor shows a 20% drop on a Saturday morning, you can reach someone. Not a ticketing portal. Not a message that says we’ll call you Monday. Gus is the one who picks up.
We send background-checked, uniformed technicians to every Claremont home. You know who’s walking up the driveway before they get there. And our 90-Day Done Right Promise means if we fix something and it’s not done right, one call brings Gus back. In writing. On every job.
When you search for Solar Panel Repair in the Inland Empire, you’ll find plenty of options. Most of them aren’t local. We are. We work the Claremont neighborhoods from the Village to the foothills, and we know what these roofs and these trees do to solar equipment.
Our Solar Panel Repair Services in Claremont
Microinverter Replacement
Claremont’s protected tree canopy means partial shade is a fact of life. Shade from a mature oak or jacaranda makes microinverter systems fail more often here than they do in treeless neighborhoods like Pomona or Ontario. Each panel has its own inverter, and each one that sits in dappled shade for years cycles through temperature swings that eventually kill it. A typical Enphase microinverter replacement in Claremont runs $350-$650 per unit, including the part, the roof work, and re-commissioning the panel on the monitoring system. We replace and upgrade them regularly.
Orphaned-System Takeover
We get calls from Claremont homeowners whose original installer disappeared. The national company sold them a system, collected the check, and stopped answering. Now the monitoring portal is dead, production is down, and the warranty claim goes nowhere. Gus’s crew takes over these systems every month. We re-commission the monitoring, diagnose every panel and inverter, and get the system producing again. On a north Claremont foothill street near the Wilderness Park, our crew took over an orphaned 24-panel system shaded by a protected parkway live oak that had been deteriorating for three years. We found two Enphase IQ7 microinverters failing intermittently and a corroded MC4 connector on the string running under the oak’s drip line, causing a 22% production deficit on the west-facing azimuth. We replaced the failed microinverters, rebuilt the connector with weatherproof sealing, and re-optimized the array’s production estimate for the existing partial shade. The homeowner’s full kWh offset came back without touching a single protected branch. That’s what an orphaned-system takeover looks like here.
Roof Leak Repair Around Mounts
Claremont has a lot of pre-WWII Craftsman bungalows near the Village, and those shallow-pitch roofs don’t forgive sloppy solar mounting. When a mount leaks, it leaks into attic storage spaces and damages original wood paneling. We repair the roof penetration, re-flash the mount, and make sure the racking is sealed correctly. A roof leak repair around solar mounts in Claremont typically runs $400-$1,100 depending on how many mounts need re-flashing and whether we’re repairing interior ceiling damage. If you see water stains on a Craftsman ceiling after a winter storm, call us before the next one.
Inverter Repair & Replacement
The string inverter on a Claremont system takes a beating. This city sits at roughly 1,100 feet at the foot of the San Gabriels, and summers regularly push past 100°F. That heat, combined with the heavy AC load it drives, shortens inverter life. A full string inverter replacement in Claremont runs $1,600-$2,400 for the unit and labor. We service Tesla, SolarEdge, and Enphase systems, and we stock common replacement parts locally so we’re not waiting on a warehouse across the country.
Wiring & Connector Repair
Mid-century ranch homes in Claremont were built with undersized 100-amp panels, and when solar gets added, the rooftop wiring does extra work. Squirrels gnaw through insulation under spreading street trees. Connectors corrode at the drip line of a jacaranda. Ground-fault alarms shut down the entire array. A wiring or connector repair in Claremont typically costs $180-$480, and it’s the most common fix we do. If your system keeps tripping a ground fault, this is where we start.

Trusted Brands We Service in Claremont
We work on the equipment Claremont homeowners already have on their roofs: Tesla, Enphase, SolarEdge, FranklinWH, and others. We keep common parts in local stock so a failed microinverter doesn’t mean waiting a week for a shipping box. Our Solar Panel Repair team is trained across battery systems, inverters, and panel-level electronics, so you don’t have to call three different companies to get one system running again. One call. One crew. Done right.
Common Solar Panel Repair Problems We See in Claremont Homes
- Protected tree shade killing microinverters: Claremont’s city-enforced tree preservation ordinance discourages significant pruning of protected canopy trees. That means solar arrays here are often designed around partial shade from oaks and jacarandas. Those partially shaded panels cycle through heat and cool-down differently than full-sun panels, and microinverters fail earlier. We see this constantly.
- Leaking mounts on Craftsman and mid-century roofs: Older homes near the Village have shallow-pitch cedar shakes and original wood paneling. A poorly flashed solar mount leaks into attic storage during winter storms. We re-flash mounts and repair the water damage before it spreads.
- Squirrel-damaged wiring under street trees: Spreading street trees create the perfect highway for squirrels. They gnaw through rooftop wiring insulation, which causes ground-fault alarms and full-array shutdowns. We repair the wiring, seal the entry points, and get your system back online.
- Inverter communication dropouts on smart-home systems: Custom foothill homes with integrated smart-home systems lose inverter communication when the protected tree canopy grows over an east-facing plane. The rapid-shutdown errors require rewiring and a microinverter grid-profile reset. We handle it without touching the tree.

FAQs - Solar Panel Repair in Claremont
Claremont’s tree preservation ordinance discourages significant pruning of protected canopy trees, so repairs here often involve working around shade that other cities don’t have. That means more microinverter replacements, more partial-shade production re-optimization, and more experience needed from your repair team than in open-lot cities like Pomona or Ontario. If your system was designed for shade and it’s underproducing, the fix may be re-optimizing the array rather than replacing parts. Call (877) 550-6892 and we’ll tell you which one you need.
It’s usually both. Craftsman roofs have shallow pitches and original cedar shakes, and solar mounts that weren’t properly flashed leak into attic storage. The fix requires re-flashing the roof penetration and repairing any water damage, not just replacing a panel. A roof leak repair around solar mounts in Claremont runs $400-$1,100. If you’re seeing stains, call (877) 550-6892 before the next storm does more damage.
Yes. We take over orphaned systems all over Claremont, including homes near the Wilderness Park where mountain-adjacent shade makes solar repairs more involved. We re-commission the monitoring, test every panel and inverter, and replace whatever failed. No system is too far gone. If your installer disappeared and your system is limping along, call (877) 550-6892. We’ll take a look and tell you what it needs.
Shade. Claremont’s protected tree canopy means many solar arrays are partially shaded, and microinverters on shaded panels run through more extreme temperature cycles than panels in full sun. That wears them out earlier. In Pomona, where lots are open and treeless, panels stay in consistent sunlight and the electronics last longer. If you’re replacing microinverters every few years, it’s probably the shade, not your system. Call (877) 550-6892 and we’ll assess whether your array needs a microinverter upgrade or a re-optimized layout.
If the tree is protected under Claremont’s ordinance, you’re unlikely to get permission for significant pruning. But the fix isn’t always cutting limbs. We can replace failed microinverters, rebuild corroded connectors, and re-optimize the array’s production estimate for the existing shade. In many cases, that restores most of the lost output without touching a single branch. If a jacaranda is shading your panels in Claremont, call (877) 550-6892 and we’ll figure out what’s actually wrong. Estimates are free, and we offer $40 off any repair over $200.
