Fast, Reliable Solar Panel Repair Across San Antonio
A sudden halt in solar production is what brings most people to our door. In San Antonio, it often follows a hail storm that swept through the 78216 corridor, or a sudden inverter shutdown on a 100-degree afternoon when the system is working hardest. The question becomes: who do you call, and how long until someone actually shows up? Gus’s Solar answers its own phone at (877) 550-6892, and we’ll have a technician at your home within 24 to 48 hours in most San Antonio neighborhoods.
We founded Solar Panel Repair as a core part of our business for one reason: a failed panel or inverter on a clear day is lost money, and around here, clear days are the norm. Our San Antonio team handles everything from a single cracked panel to a full-system diagnosis, and we don’t hand the work off to a sub. The person who answers your call is also the person who shows up with a multimeter and a tool bag.
Why Gus’s Solar Is San Antonio’s Preferred Solar Panel Repair Company
Our reputation in San Antonio is built on years of one thing: doing what we say we’ll do. When a homeowner in Terrell Hills calls about a dead inverter, we don’t promise we’ll “get back to them.” We give a time, and we’re there. When we replace a panel in Windcrest, we flash the mount correctly so the next rain doesn’t find a way inside. The result is a strong base of repeat customers and referrals from neighbors who watched the whole thing get fixed right the first time.
Local knowledge is also part of what sets us apart. We understand how CPS Energy’s interconnection rules affect repair work, and we know that a repair on a clay tile roof near Monte Vista requires different mounting hardware than a repair on an asphalt shingle in a newer development off 1604. That knowledge means the repair price we quote is the price you pay, because we’ve already accounted for the real conditions up there.
And you won’t sit on hold with a call center. A live person answers 24/7, including during a July storm that’s knocked out power and taken your array offline. Gus Petrakis, our owner, publishes his name and license number and stands behind every job with a written 90-Day Done Right Promise. If it’s not right, he makes it right. No fine print.
Our Solar Panel Repair Services in San Antonio
Inverter Repair & Replacement
The inverter is the heart of your system, and in San Antonio’s heat, they fail more often than panels do. We diagnose whether the issue is a capacitor, a cooling fan, or a full unit failure, then recommend repair or replacement based on honest math. A typical string inverter replacement in San Antonio runs $1,800 to $3,400 installed, depending on capacity and brand. We commonly replace SolarEdge and Enphase units, and we keep parts in stock for faster turnaround.

Microinverter Replacement
If your system uses microinverters and individual panels have gone dark, the cause is often a failed microinverter under one panel. We locate the affected unit, replace it, and verify production returns across the array. Replacing a single microinverter in San Antonio generally costs $400 to $700 including labor and parts. It’s a same-visit fix in most cases, and we’ll confirm your monitoring system is reporting correctly before we leave.

Wiring & Connector Repair
Loose MC4 connectors, chewed wiring, and weather-damaged junction boxes are common problems on San Antonio rooftops, particularly after a big storm or when squirrels have found a nesting spot under the array. We inspect the full circuit path, replace damaged conductors, and seal every penetration. Wiring and connector repairs typically run $200 to $600 depending on how much of the run needs replacement. It’s the kind of repair that’s easy to ignore until it isn’t.

Panel Replacement After Damage
Hail is a fact of life in San Antonio, and after a storm with stones over 1.5 inches, cracked glass and micro-fractures start showing up within weeks. We assess the damage, document it for your insurance claim, and replace the affected panels with compatible units matched to your array’s output specs. A single panel replacement in San Antonio typically costs $500 to $900 installed, not including any insurance deductible you may carry. We also take over orphaned systems when the original installer has disappeared, which happens more often than we’d like to admit in this market.

Trusted Brands We Service in San Antonio
We repair and maintain systems from the brands San Antonio homeowners actually have on their roofs: Tesla, Enphase, SolarEdge, SunPower, Panasonic, Qcells, REC, Canadian Solar, JinkoSolar, and FranklinWH. If your system uses Canadian Solar glass with Enphase microinverters, we can source exact matches. If you’ve got a JinkoSolar array feeding a FranklinWH battery, we’ll diagnose both sides of the system. We keep common replacement parts in our San Antonio office and warehouse, which means many repairs are completed on the first visit rather than after a two-week parts delay.
Common Solar Panel Repair Problems We See in San Antonio Homes
- Post-hail micro-fractures: San Antonio sits in a high-frequency hail corridor, and even panels that look fine from the ground can develop hairline cracks that slowly degrade output. We check for IEC 61215 hail-class ratings and document damage for insurance claims. If a storm dropped stones near your roof, we recommend a production audit within a month.
- Inverter thermal shutdowns: San Antonio’s 100-plus degree July and August afternoons push inverters to their thermal limit. When an inverter overheats and cycles off, production drops to zero during peak hours. We upgrade cooling, reposition units out of direct sun, or replace the inverter entirely when needed.
- Roof leaks around mounts: The older bungalows and craftsman homes in the 78201 and 78204 corridors often have low-pitch roofs and aging underlayment. A poorly flashed mount from the original install leaks into the attic months later. We remove the mount, repair the decking, and re-flash to a standard that holds through San Antonio’s fall and spring rain seasons.
- Squirrel and rodent damage under arrays: Panels raised a few inches off the roof create a shaded, protected space that squirrels in Alamo Heights and Kirby use as a year-round home. We install perimeter mesh, repair chewed conductors, and relocate nests. This is a preventative fix that costs far less than replacing an entire string of wires.
Pricing for Solar Panel Repair in San Antonio, TX
Nobody likes a repair estimate with no numbers in it, so here’s the truth about what things cost around here. A diagnostic service call in San Antonio runs $150 to $250, and that fee is credited toward any repair we complete on the same visit. Wiring and connector fixes start around $200 and top out near $600. Microinverter replacement runs $400 to $700 per unit. String inverter replacement sits between $1,800 and $3,400. A single panel replacement after hail or impact damage typically falls between $500 and $900.
What changes the price? Roof type, access difficulty, system age, and whether we’re matching an existing panel from a discontinued line. Clay tile roofs, common in Spanish-Colonial homes across the inner city, require tile-replacement mounts that add labor time compared to asphalt shingle. We quote the work after looking at your actual roof, never from a street photo. Call (877) 550-6892 for a free estimate, and we’ll give you a number you can hold us to.
