Why Gus’s Solar Is Marble Falls’s Preferred Solar Panel Repair Company
We didn’t parachute into Marble Falls. We’ve been driving these roads for over a decade, and we know what Hill Country sun, hail, and granite ledges do to a solar array. When a PEC customer near Granite Mountain calls about a production drop, we don’t guess. We check the inverter logs first, then the roof.
Gus Petrakis started this company in 2011, locally owned since day one. His crew does the work. Background-checked, uniformed, and they’ll tell you their names before they put a ladder on your wall. You don’t get a subcontractor you’ve never met. You get the same faces who’ll be at the hardware store next weekend.
Every repair carries our 90-Day Done Right Promise. If it’s not right, Gus comes back and makes it right, in writing. That’s not a marketing line. That’s how we’ve kept customers in Marble Falls calling us for over a decade.
We also answer the phone 24/7. A live person. When a storm rolls through the Highland Lakes and your inverter starts throwing fault codes at midnight, you call and a human picks up. Not a recording.
For anyone who’s been burned by an out-of-state installer that quoted one number on the phone and another at the door: our pricing is upfront, it’s based on your actual system and your actual bill, and nobody here will ask you to sign tonight. Take two weeks. Think about it. The price will be the same.

Panel Replacement After Damage
Hail is the big one in Marble Falls. The Highland Lakes sits in a hail-prone corridor, and a lot of systems installed five to ten years ago went in before IEC 61215 hail-impact-rated panels became standard here. A cracked panel doesn’t always fail immediately. It delaminates slowly, lets moisture in, and production bleeds off month after month. You notice it first on your PEC bill, when the avoided-cost credit shrinks. We replace damaged panels with hail-rated units from Qcells or REC and match the existing array’s electrical specs so the string stays balanced.
Microinverter Replacement
North-facing and northwest-facing arrays are common here, especially on lakefront lots positioned for the view rather than the sun. Those systems almost always run microinverters because of the poor azimuth. When a microinverter fails, you lose one panel’s production, not the whole string, which is good. The bad news: a single failed microinverter on a multi-plane roof is easy to miss for months. Enphase systems report per-panel data, so we can pinpoint the dead unit fast. Replacement in Marble Falls, including the part and labor, typically runs $350 to $600 per microinverter.
Roof Leak Repair Around Mounts
Standing-seam metal roofs are everywhere in the lakefront and golf-community builds around Marble Falls, and they need clamp-based racking, not penetration mounts. When an installer used standard lag-bolt mounts on a metal roof, it leaks. The first sign is usually a water stain in the attic, not an electrical fault. By the time the fault appears, the decking’s wet and the damage spreads fast. We remove the old penetration mounts, install proper clamps, seal the holes, and flash every roof penetration correctly. Gus’s crew does this in-house.
Inverter Repair & Replacement
Marble Falls summers push rooftop inverters hard. Ambient temperatures regularly cross thermal thresholds, and a string inverter bolted on a south-facing wall or too close to the roof deck will thermally derate. You lose production silently, and most owners blame the panels. We test the inverter first, and if it’s failed or derating, we replace it with a properly ventilated unit or relocate it away from direct sun. Full string inverter replacement for a typical 6 to 9 kW system in Marble Falls runs $1,200 to $2,400 installed.

Trusted Brands We Service in Marble Falls

If your system is older or the original installer is out of business, we can still source the parts. Orphaned systems are a specialty.
Common Solar Panel Repair Problems We See in Marble Falls Homes
These are the failure patterns we see over and over in the 78654 zip code. If any of these sound familiar, call us before the next storm, not after.
- Hail cracks on non-IC 61215 panels. Minor hail that wouldn’t dent a car can micro-crack older panels. Homeowners don’t see it. They see a quiet production decline and a shrinking PEC credit. We inspect panels after hail events, not just when the inverter alarms.
- Rooftop inverter overheating. In Marble Falls summers, inverters mounted flush to the roof deck or on unshaded south walls run too hot. Production drops, panels get blamed. We relocate or re-ventilate inverters to restore output.
- Standing-seam roof leaks at old penetration mounts. High winds work penetration mounts loose on metal roofs. Water gets under the ridge caps and into the attic. By the time it shows on the ceiling, the deck’s been wet for months. We find the leak at the mount, not the water spot inside.
- Corroded rooftop junction box connections. High UV, hail impact, and temperature swings degrade wire insulation faster in the Hill Country than in shaded urban settings. Arc faults and rapid-shutdown nuisance trips follow. We trace the circuit, replace the damaged conductors, and seal the box properly.

FAQs - Solar Panel Repair in Marble Falls
Yes, and it’s the question most Marble Falls homeowners miss. PEC doesn’t pay retail net metering rates. They credit exported solar at an avoided-cost rate well below what you pay for electricity. That means a repaired panel that pushes extra production onto the grid has less financial upside than a repaired panel that offsets your own consumption. If your system overproduces after a repair and you’re exporting more, the repair still pays off over time, but pairing it with battery storage or shifting loads to daytime changes the math. Call (877) 550-6892 and we’ll model the actual numbers off your PEC bill.
Not usually for a panel-for-panel swap, but Marble Falls sits in a high-wind exposure zone, and the inspector may want documentation that the replacement panels meet the wind-load rating of the original engineered racking. If you’re replacing multiple panels or moving racking, a recertification can be required. We handle the paperwork and work with the inspector directly. Your 90-Day Done Right Promise covers the work, and we make sure the inspection passes before we call the job complete.
Hail damage shows a distinctive starburst or bulls-eye crack pattern with impact points you can feel. Manufacturing defects, thermal stress, or physical damage from tree limbs look different. Hail cracks often concentrate on the upward-facing panels, not the ones facing the lake view. We inspect on-site and match the pattern to actual weather events in Marble Falls. If it’s hail, insurance often covers the panel replacement, and we’ll document it for your claim.
Microinverters in Marble Falls fail less often than string inverters overall, but when they do fail it’s usually due to heat exposure on unventilated roof planes or water intrusion at the trunk cable connections. The Hill Country’s high-UV, hail-impacted environment stresses rooftop electronics more than ground-mounted or garage-mounted components. We see more microinverter failures on standing-seam metal roofs where the trunk cable was run without proper UV-protective conduit. Replacement is straightforward and we stock Enphase microinverters locally.
The old penetration mounts. On a standing-seam metal roof, racking should clamp to the seams, not screw through the metal deck. When an installer used penetration mounts with rubber gaskets, those gaskets dry out and crack in the Highland Lakes sun. High winds then work them loose, and every penetration becomes a leak point. The fix is pulling the old mounts, installing proper seam clamps, and sealing the holes with the right metal-roof sealant. Call (877) 550-6892 for a free estimate and we’ll inspect every mount on your roof, not just the one that’s leaking.
Your Solar Panel Repair Team in Marble Falls
Last spring we took over an orphaned 6 kW system on a lakefront limestone cottage near Granite Mountain. Hail had cracked two Qcells panels and a squirrel had chewed through an Enphase microinverter trunk cable. The home’s main roof faces northwest toward the lake, so the array was already split across multiple planes. Our tech replaced the damaged panels with IEC 61215 hail-rated REC units and rewired the microinverter branch, restoring production while keeping the rapid shutdown circuit compliant with PEC’s updated interconnection requirements. That’s the kind of repair work we do most weeks in Marble Falls.
When your system isn’t producing, don’t wait. A small wiring fault becomes a roof leak becomes a mold problem becomes an insurance headache. We’d rather fix it before the next hailstorm. Call (877) 550-6892 for a free estimate. A live person answers. Gus’s name is on the truck, and the work carries a 90-day promise in writing.
