Fast, Reliable Solar Panel Installation Across San Antonio
If you’re weighing solar for your San Antonio home, here’s the straight answer: a professionally installed residential system in this market typically runs between $13,500 and $27,000 before the federal tax credit, with most of the homes we quote landing in the $16,000 to $22,000 range. The final number moves based on your roof’s condition, what CPS Energy’s interconnection process requires, and whether your house sits in a historic district. Gus’s Solar handles everything from the first bill analysis to the final utility sign-off, and Gus Petrakis himself answers the phone at (877) 550-6892 when questions come up.
We’re local to San Antonio. That means we know CPS Energy’s paperwork by heart, we’ve pulled permits from the city’s Development Services office on North Main, and we’ve installed on houses from Monte Vista to Windcrest. Not one part of this process gets handed to a sub crew three states away. The same team that quotes your system is the team on your roof.
Why Gus’s Solar Is San Antonio’s Preferred Solar Panel Installation Company
Gus Petrakis has run this shop since 2011, and he’s built the business the old way: a published address, a published license number, and his own name on every job. San Antonio homeowners have dealt with enough door-knockers selling tomorrow’s rate hike and vanishing after the check clears. Gus does the opposite. Bring him your CPS Energy bill and he’ll show you the year-25 production numbers, not the day-one brochure figure. If a salesman needs an answer tonight, the answer is no. Gus tells every customer to take two weeks. The price will be the same.
Reviews from San Antonio customers consistently point to the same things: the quote matched the invoice, the crew showed up when they said they would, and when something needed adjusting, one call brought Gus back. Every install carries the 90-Day Done Right Promise in writing. If it isn’t right, he makes it right. A live person answers the phone 24/7, which matters when your system throws a fault at 9 p.m. and you want a human, not a ticket queue.
The L.O.C.A.L. values we operate by aren’t a marketing slogan. Local roots, On time, Community first, Accountable, Loyal. That’s how a San Antonio shop should run.
Our Solar Panel Installation Services in San Antonio
From a 1920s bungalow in Beacon Hill to a new build off Loop 1604, our Solar Panel Installation team sizes every system to the actual roof and the actual bill. Here’s what San Antonio homeowners call us for most:
Rooftop Solar Installation
This is the core of what we do across San Antonio ZIPs like 78212, 78213, and 78214, and we back every install with Solar Panel Cleaning - San Antonio support. We evaluate your roof structure, check the decking, and mount panels for maximum South Texas production. On the inner-city homes with low-pitch roofs and original wood decking, we take the extra step of inspecting the underlayment before any racking goes up. On suburban tract homes with asphalt shingles, the job moves faster.

Solar System Design & Permitting
Every San Antonio install runs through CPS Energy’s own interconnection process, which is different from what the investor-owned utilities elsewhere in Texas use. We handle the full permitting package, the CPS Energy application, and the final utility approval. For homes in the King William or Monte Vista historic districts, we also prepare the HDRC application and design arrays that keep panels off street-facing roof planes.

Solar Panel Replacement
Hail happens in San Antonio. When a storm cracks panels or degrades output, we replace them with matched or upgraded equipment. We stock common panels locally, so San Antonio customers aren’t waiting on a truck from Houston. If your system is 10 to 15 years old and underperforming, we’ll give you an honest read on whether replacement beats repairing.

Roof-Mount & Tile Roof Solar
The Spanish-Colonial and mission-style homes across the inner city often have clay or concrete tile roofs. These require specialized tile-replacement mounts and a slower, more careful installation than shingle roofs. Gus’s crew does this work in-house. We flash every penetration properly, and we’ve installed on enough tile roofs in 78201 and 78204 that we know what the city inspectors look for.

Trusted Brands We Service in San Antonio
We install and service equipment from Tesla, Enphase, SolarEdge, and FranklinWH, among others, including San Antonio Solaredge service. For San Antonio customers, that means we can match your system to your roof’s sun exposure and your CPS Energy bill without pushing one brand for every house. We keep a local stock of Enphase microinverters and SolarEdge optimizers, so common warranty replacement parts don’t sit in shipping limbo. Whatever brand ends up on your roof, it’s backed by our install workmanship and the 90-Day Done Right Promise.
Common Solar Panel Installation Problems We See in San Antonio Homes
Every market has its own failure patterns. In San Antonio, here’s what shows up most:
- Hail-damaged panels and microcracks. San Antonio sits in a high-frequency hail corridor where large-hail events routinely exceed 1.5 inches. Panels without proper impact ratings can develop microcracks that slowly bleed output. We spec panels with strong IEC 61215 hail-class ratings and walk customers through what their insurer will and won’t cover.
- Historic district design restrictions. In the Monte Vista and King William districts, the HDRC can block street-visible arrays. We’ve seen homeowners fall in love with a 30-panel system only to learn the HDRC will approve 20. We disclose that trade-off in the proposal, before you spend a dime.
- Old wood decking under original tile. Pre-1960s homes in the 78201-to-78210 corridor often have decking that has never been touched. We inspect it before racking goes up and tell you straight if the roof needs work first. Some companies skip that step and bolt into wood that shouldn’t hold a panel.
- CPS Energy interconnection delays. Municipal utility timelines don’t move because a salesman wants commission this quarter. We know CPS Energy’s process well enough to submit clean applications the first time, but we also tell customers honestly when the utility’s queue is the bottleneck.
Pricing for Solar Panel Installation in San Antonio, TX
Here’s what we see across San Antonio in 2026. A straightforward asphalt-shingle install in a neighborhood like Windcrest runs $15,000 to $21,000 for a 7 to 9 kW system. Tile roof installations on older inner-city homes run higher, $20,000 to $27,000, because of the specialized mounting and slower labor. Historic district jobs in Monte Vista or King William can lose 30 to 40 percent of usable capacity to HDRC setback rules, which brings the per-watt cost up. A panel replacement after hail damage typically runs $350 to $750 per panel installed, depending on brand and access.
We quote off your actual CPS Energy bill, not a brochure estimate. The number you see is the number you pay. If you’ve got a written estimate from another company, bring it in and Gus will give you a free second opinion. No signature wanted tonight.

FAQs - Solar Panel Installation in San Antonio
For a standard rooftop install, most San Antonio customers get on the schedule within 7 to 10 days after permits clear, or sooner if you need our EV Charger Installation in San Antonio bundled with your solar project. CPS Energy’s interconnection approval is usually the pacing factor, not our crew availability. Call (877) 550-6892 and we’ll give you a straight timeline for your specific ZIP. A live person answers, 24/7.
Yes, we install across San Antonio including 78211, 78212, 78213, and 78214, plus the historic districts around Monte Vista and King William. No address is too small or too complicated. If your house is in an HDRC district, we’ll include the design review process in your quote and tell you exactly what capacity is feasible before you commit.
When a system fails after a big storm, we can usually get a technician to your San Antonio home the same day or next morning through our San Antonio Solar Panel Maintenance & Monitoring team. Gus’s own crew handles the work. We don’t route you to a national call center. If you’re a current customer, call and Gus will pick up or call right back.
Labor rates in San Antonio are fair and often slightly lower than Austin or Dallas, but the bigger difference is the utility. CPS Energy’s net metering structure and interconnection rules affect your long-term savings more than a few hundred dollars on install cost. We also cross-train with Solar Battery Storage & Backup in San Antonio so you can pair panels with a FranklinWH or Tesla battery if you want backup power during CPS outages or severe weather. That math is best figured on your actual bill, which we do for free.
Every install carries the 90-Day Done Right Promise in writing, plus manufacturer warranties on panels and inverters. If something isn’t right, Gus makes it right. No fine print, no third-party warranty company. For system upkeep, we also handle Solar Panel Cleaning in San Antonio to keep production up between hailstorms and cedar pollen season.
