Solar panel repair in San Antonio typically runs $180-$650 for most fixes, and our crew can usually be at your home within 24 to 48 hours. That’s the straight answer. Whether your inverter quit in the middle of a CPS Energy billing cycle or hail cracked a panel on your Alamo Heights roof, we diagnose the problem, quote you an honest number, and fix it without dragging you through a sales pitch.
Gus Petrakis founded this company in 2011 because he was tired of seeing San Antonio homeowners get burned by out-of-state installers who vanished after the paperwork cleared.

You’ll get a live person when you call, not a ticketing portal.
Why Gus’s Solar Is San Antonio’s Preferred Solar Panel Repair Company
Twenty-nine years in the solar trade teaches you things you can’t learn from a franchise playbook. In San Antonio specifically, we’ve learned that a repair on a 1920s bungalow in Monte Vista is a completely different job from one on a 2018 tract home off Loop 1604. The rooflines are different. The underlayment is different. The HDRC rules are different. And the customer deserves a crew that knows the difference before the ladder goes up.
Here’s what that means for you. When your system fails, we don’t send a salesperson with a binder full of financing options. We send a background-checked, uniformed technician from Gus’s own crew. That person has crawled across Spanish-Colonial tile roofs in King William, worked around clay tile mounting hardware on pre-1960s bungalows, and knows which inverter failures CPS Energy’s inspection process will flag before the city even looks at it.
Our San Antonio customers call us about hail damage, sudden production drops, inverter errors, and orphaned systems from installers who went out of business. They call us because someone in their neighborhood already did. And when they call, they talk to Gus or someone on his team who can actually answer the question on the spot.
Our Solar Panel Repair Services in San Antonio
Inverter Repair & Replacement
A failed inverter is the most common reason a San Antonio system goes dark. Older string inverters, especially SolarEdge and older SunPower models, run hot in our summers and fail earlier than their rated lifespans. We diagnose whether the fault is a capacitor, a communication board, or a full unit replacement. In San Antonio, inverter replacement runs $1,100-$2,400 depending on the model and whether we need to re-pull communication wiring to meet current code. Before we swap anything, we check your CPS Energy interconnection agreement so the replacement passes inspection on the first pass.

Microinverter Replacement
Microinverters fail less often than string inverters, but when one goes out on an Enphase system in a San Antonio neighborhood, it drags down the whole branch circuit’s production. You might not even notice it until your CPS Energy bill ticks up. Replacing one microinverter typically runs $350-$550 including the part, and the work usually takes under two hours. We stock Enphase IQ7 and IQ8 series replacements in our San Antonio office so we’re not waiting on a distributor in Dallas when your panels are earning nothing.

Wiring & Connector Repair
Squirrels, hail, and UV exposure all take a toll on exposed DC wiring and MC4 connectors across San Antonio roof decks. We find chewed insulation, corroded connectors, and overheated junctions that arc-fault breakers have already tripped or are about to. Most wiring repairs run $180-$400 depending on how much of the run needs replacing and how accessible your attic chase is. On older homes in 78201 and 78204, we often re-route wiring through existing conduit chases to avoid altering anything visible from the street.

Panel Replacement After Damage
Hail in San Antonio isn’t an if, it’s a when. The local corridor sees large-hail events exceeding 1.5 inches more often than most Texas cities, and a single panel strike can cost you 3-5% of your system’s daily output. Replacing a damaged panel runs $400-$800 installed, depending on the panel’s wattage and whether you’re matching an existing string or mixing panel types. If your original panels are discontinued, we can source equivalent-rated replacements and rebalance the string so the new panel doesn’t bottleneck the rest.

Roof Leak Repair Around Mounts
This is the repair nobody thinks about until the ceiling stain appears. San Antonio’s clay tile and concrete tile roofs, especially in the Spanish-Colonial revival homes across the inner city, are unforgiving with aftermarket mounting hardware. If a mount wasn’t double-flashed, water gets under the aged underlayment and works its way down. We remove the mount, repair the flashing, and re-seat the racking so it holds for the life of the roof. Expect $300-$650 per mount area, more if tiles are brittle and need replacing.

Trusted Brands We Service in San Antonio
Our San Antonio repair crew works on Tesla, Enphase, SolarEdge, SunPower, Panasonic, Qcells, REC, Canadian Solar, JinkoSolar, and FranklinWH equipment. For the older systems we see most often in historic neighborhoods, Panasonic and Canadian Solar modules are common, and we keep their mounting hardware and connectors in stock at our San Antonio shop. JinkoSolar panels show up on a lot of the newer installs north of Loop 1604. We service them all, and we don’t tell you a system is too old to fix just because we’d rather sell you a new one.
Common Solar Panel Repair Problems We See in San Antonio Homes
- Hail damage on low-pitch pre-1960s roofs. In neighborhoods like 78201 and 78204, many homes still carry original wood decking that flexes under large-hail impact. The flex transfers energy to the panel glass and the tile, leaving cracks that are easy to miss from the ground. We perform full-array inspections after every major hail event.
- Inverter failures that leave systems dark for months. A surprising number of San Antonio systems sit offline because the homeowner doesn’t notice, or because their original installer is out of business and CPS Energy won’t re-approve the interconnection without a licensed contractor involved. We take over orphaned systems and handle the CPS Energy paperwork ourselves.
- Roof leaks around mounts on original Spanish-Colonial tile. Clay tile roofs in the 78201-78210 corridor were never designed for solar racking. Every mounting point must be double-flashed, or the aged underlayment will eventually let water through. We see this on original installs from the early 2010s that are only now showing the effects.
- Microinverter outages that quietly drain production. A single failed microinverter on Enphase systems can sit undetected for a year or more. By the time the homeowner notices, they’ve lost hundreds of dollars in CPS Energy credits. Our annual inspection catches these before they become a year-long slow leak.

FAQs - Solar Panel Repair in San Antonio
Yes, and this catches a lot of people off guard. The HDRC’s ‘not visually prominent from the street’ rule applies to any change that alters the street-facing roofline, including repair work that replaces panels with different-dimension or different-mounted equipment. The practical consequence in King William (78204) and Monte Vista (78201) is that some repairs have to be done on rear roof faces or behind parapets, which can cut usable array capacity by 30-40% compared to an unconstrained layout. We flag this before we start, not after the inspector shows up. Call (877) 550-6892 and we’ll walk you through exactly what your block’s HDRC rules mean for your repair.
Because CPS Energy runs its own municipal interconnection and net metering process, separate from the PUC of Texas framework most of the state follows. When a system is repaired, the interconnection agreement has to be updated with the utility before the new equipment’s production is credited correctly. If your installer fixed the panels but never filed the updated paperwork, your bill will keep showing old true-up charges. We file the CPS Energy paperwork with every repair we complete, and we follow up until the utility confirms it’s processed. That single step is why many San Antonio homeowners see their bills stay high for months after a repair that should have fixed the problem.
You can’t tell from the ground. A panel that looks clean from the driveway can have micro-fractures in the cells or hairline cracks in the glass that only show up under a thermal inspection. In San Antonio’s hail corridor, where 1.5-inch+ hail events are common, we recommend a full-array inspection after any storm that leaves visible damage on your car or fence. The inspection takes under an hour, and we’ll document any hits with photos you can send to your insurance carrier. The first thing to check is your monitoring portal for production drops, but absence of a production drop doesn’t mean absence of damage.
Yes, this is one of the most common calls we get in San Antonio. Orphaned systems are everywhere, and CPS Energy’s rules don’t let a homeowner file interconnection updates without a licensed contractor on record. We take over the system documentation, re-file the interconnection paperwork, and bring the system back to code. From there, we monitor it and you call one number for anything. Gus’s Solar has been taking over orphaned systems across San Antonio since we opened, and we’ve never walked away from one because it was too far gone.
The honest answer depends on two things: how much life your panels actually have left, and whether CPS Energy’s current interconnection rules favor a repair or a reconfiguration. If your panels are 12-18 years old and still producing above 80% of rated output, a microinverter retrofit makes sense, especially if your string inverter has failed twice. A full Enphase microinverter conversion on a San Antonio home typically runs $2,800-$5,500 depending on panel count, and it eliminates the single-point-of-failure problem that keeps taking your system down. But if your panels are nearing the end of their service life, sometimes the smarter money is a simple inverter repair and a plan to replace the whole array in three to five years. We’ll give you both numbers and let you decide. Bring us a bill, we’ll bring you the math.
