Why San Antonio Homeowners Choose Gus’s Solar
Most solar companies in San Antonio are either door-knockers working on commission or out-of-state outfits running a local phone number. Gus Petrakis is neither. He founded this company, his name is on the truck, and when something goes wrong three years after install, he’s the one who picks up the phone. That’s not a sales pitch, it’s how we’ve operated since day one.
We work throughout the city, from the tree-lined streets of Alamo Heights to the older bungalows of Jefferson and the newer subdivisions off Bandera Road in the 78216 and 78217 ZIP codes. Homeowners in Terrell Hills and the Monte Vista area regularly call us for second opinions after a pushy sales crew quoted a system size that didn’t match their actual usage. Bring us a bill, we’ll bring you the math. Take two weeks to think about it. The price will be the same.
Every job carries our 90-Day Done Right Promise in writing. Gus’s background-checked, uniformed crew does the installation themselves. We don’t hand your roof off to a sub crew we’ve never met. And when CPS Energy’s rules or an HDRC design review gets complicated, we handle it because we’ve been through it hundreds of times in this city.
Solar Services We Offer in San Antonio
Solar Panel Installation
We design and install rooftop solar systems sized to your actual CPS Energy usage history, not a generic square-footage formula. System design accounts for San Antonio’s hail exposure, roof type, and any historic-district restrictions that apply to your address. Learn more about Solar Panel Installation in San Antonio.
Solar Battery Storage & Backup
CPS Energy’s net metering caps and summer outage risk make battery storage a practical upgrade for many San Antonio homes. We install FranklinWH and other battery systems sized to cover your critical loads when the grid goes down. Learn more about Solar Battery Storage & Backup in San Antonio.
Solar Panel Cleaning
San Antonio’s oak pollen, summer dust, and post-storm debris cut into panel output more than most homeowners realize. We clean panels safely and check connections while we’re up there. Learn more about Solar Panel Cleaning in San Antonio.
EV Charger Installation
Charging an EV at home costs a fraction of filling a gas tank, especially when paired with solar production. We install Level 2 chargers with proper panel and wiring upgrades. Learn more about our EV Charger Installation - San Antonio.
Solar Panel Maintenance & Monitoring
Panels degrade slowly, but inverters, connectors, and roof penetrations need attention. We monitor your system’s output and come out before small dips become big repairs. Learn more about San Antonio Solar Panel Cleaning.
Solar Panel Repair
Hail cracks, loose racking, failed microinverters. We diagnose and repair all major panel brands, including Panasonic, Canadian Solar, and JinkoSolar. Free second opinion on any written estimate. Learn more about solar panel repair in San Antonio.

Why San Antonio’s Climate & Housing Affect Solar
San Antonio sits in one of the highest solar-irradiance zones in Texas, averaging 220+ sunny days per year with strong June through August peak production. That’s the good news. The bad news is that this city also sits in a high-frequency hail corridor where large-hail events routinely exceed 1.5 inches. Panel hail-impact ratings aren’t a marketing bullet point here, they’re an insurance-underwriting reality. We spec panels accordingly and make sure your system is built to survive a March storm cell.
San Antonio’s housing stock adds another layer most installers ignore. The 78201 through 78210 corridor is dominated by pre-1960s bungalows, craftsman cottages, and single-story masonry homes with low-pitch roofs. Many still carry original wood-decking underlayment that needs evaluation before racking goes up, along with clay and concrete tile roofs that require specialized tile-replacement mounting hardware. These homes are not the same job as a 2018 tract house in Stone Oak. We bid them differently, and we tell you why before you sign.
Pricing for Solar in San Antonio
Solar pricing in San Antonio runs on a wide range because system size, roof type, and historic-district requirements all change the equation. Here’s what we’re seeing across current San Antonio jobs:
- Full residential system (8-12 kW): $22,000-$36,000 before federal tax credit

FAQs About Solar in San Antonio
CPS Energy runs its own interconnection and export-rate structure separate from the PUC of Texas framework, so your solar credits are governed by CPS Energy’s current solar rate schedule, not state net-metering rules. That’s why every quote we write in San Antonio is built from your actual CPS Energy bill and current export rates, not a generic estimate. Call (877) 550-6892 and we’ll walk you through the exact numbers for your address.
Yes, if you live in the King William or Monte Vista historic districts (78204, 78201), the city’s Historic and Design Review Commission must approve any rooftop solar visible from the public right-of-way, which can add weeks and sometimes forces panels onto rear roof faces or behind parapets. We prepare HDRC-ready proposals and disclose any capacity trade-offs before you commit.
A typical residential system in San Antonio runs $22,000 to $36,000 before the federal tax credit, depending on roof type, system size, and historic-district requirements. The exact number comes from your CPS Energy usage history, not a square-footage chart. Call (877) 550-6892 for a free, no-pressure estimate.
San Antonio sits in a high-frequency hail corridor where large-hail events routinely exceed 1.5 inches, so hail-impact ratings are a genuine consideration for local solar systems. We spec panels with appropriate IEC 61215 hail-class ratings and can help you understand what your homeowner’s insurance will cover, and we offer San Antonio Solar Battery Storage & Backup to keep you running when the grid goes down. If a storm does damage your system, we repair all major brands and offer a free second opinion on any written estimate.

What San Antonio Customers Say
"He flashed every roof penetration properly and showed me the flashing before it went down. Three roof seasons on and not a drop anywhere."
- Philomena Achara"Panel level monitoring so I can see each one, proper stainless clips under the array rather than zip ties, and he walked me under it with a torch to show me before he signed off."
- Cassius Delacroix"Gus's own crew did the install. Not a subcontractor who had never met him, which is what the big outfit quoted me and could not tell me who would actually be on my roof."
