Fast, Reliable Solar Panel Installation Across San Antonio

A typical rooftop solar installation in San Antonio runs between $18,500 and $34,000 before incentives, and most homeowners see CPS Energy approval within four to eight weeks. That’s the honest range, not a bait number designed to get a salesman through your door. We’re Gus’s Solar, and we’ve been wiring systems into San Antonio’s particular mix of sun, hail, and municipal utility rules long enough to tell you exactly what your roof can handle and what your bill math actually looks like. Call (877) 550-6892 for a straight answer.

This page is built for homeowners inside the loop and across the northern growth edge, from the clay-tile bungalows of Monticello Park to the tract-home cul-de-sacs off Culebra. If you’re weighing solar in San Antonio, you need someone who knows the difference between a CPS Energy interconnection queue and a PUC filing. They are not the same thing, and getting it wrong costs you weeks.

Why Gus’s Solar Is San Antonio’s Preferred Solar Panel Installation Company

Gus Petrakis started this shop in 2011 and never hired a sales team. When you call, you get a live person, 24/7, not a voicemail tree and not a call center. When the crew shows up in Alamo Heights or Terrell Hills, they’re background-checked, uniformed, and employed by Gus directly. No subs. No mystery installers. The name on the truck is the name answering the phone.

We’ve pulled permits through the HDRC for homes in Monte Vista (78201) and King William (78204). We’ve worked roofs in 78213 and 78214 that other installers walked away from because the decking was original and the tiles were fragile. That local history matters. It means we know what the city will approve before we file, and we know which racking systems survive a San Antonio hailstorm without cracking a tile or voiding a roof warranty.

Every job comes with the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Gus back. We also quote the year-25 output off your actual CPS Energy bill, not the day-one brochure number. Bring me a bill, Gus says. I’ll bring you the math. Take two weeks. Think about it. The price will be the same.

Our Solar Panel Installation Services in San Antonio

We don’t do “solar solutions.” We do specific work, on specific roofs, under specific San Antonio rules. Here’s what that actually looks like. For the full picture on system types and sizing, visit our Solar Panel Installation overview page.

Solar System Design & Permitting

Every San Antonio system starts with a design that accounts for CPS Energy’s interconnection requirements, not just roof angle and sun hours. We handle the full permit package, including HDRC applications when your home sits in a certified historic district. A typical design and permitting package in San Antonio runs $1,200 to $2,800, depending on jurisdiction and historic overlay.

Solar System Design & Permitting

Roof-Mount & Tile Roof Solar

Clay tile and concrete tile roofs dominate the Spanish-Colonial revival homes across the inner city. Standard penetration mounts will crack those tiles. We use tile-replacement mounting hardware on every tile roof in San Antonio, and we go slow. A tile-roof installation typically adds one to two days versus asphalt shingle, and the mounting hardware adds roughly $1,500 to $4,000 depending on array size.

Roof-Mount & Tile Roof Solar

Solar Panel Replacement

Hail takes out panels in San Antonio with depressing regularity. If your system took a hit and production dropped, we can match or upgrade the existing array. Replacement panel costs in San Antonio run $350 to $800 per panel installed, plus any racking or inverter work. We stock common Enphase and SolarEdge components locally, which means faster turnaround than waiting on a shipment from Houston.

Solar Panel Replacement

Solar Interconnection & Utility Approval

This is where San Antonio is genuinely different from Dallas or Austin. CPS Energy runs its own interconnection queue, its own export-rate schedule, and its own net metering policy. We handle the entire application, the follow-ups, and the final energization sign-off. Interconnection and utility approval services in San Antonio run $800 to $2,200, and we don’t file until the design is HDRC-clean when applicable.

Trusted Brands We Service in San Antonio

We work with hardware that holds up to San Antonio’s hail season and production demands: Enphase microinverters, SolarEdge optimization, Tesla Powerwall integration, and FranklinWH battery systems. We don’t push one brand as a catch-all. The right inverter depends on your shading, your roof geometry, and whether you’re adding battery backup down the line. We stock common Enphase and SolarEdge parts locally for San Antonio customers, which means a failed microinverter gets swapped in days, not weeks.

Common Solar Panel Installation Problems We See in San Antonio Homes

  • HDRC visual-prominence rejections in historic districts. A system that passes CPS Energy structural review can still get blocked by the Historic and Design Review Commission if panels are visible from the street. This forces a redesign to rear roof faces and can cut expected annual production by 30 to 40 percent. We disclose this trade-off in our proposals before you fall in love with a system-size number.
  • Cracked clay tiles from standard penetration mounts. Installers who don’t use tile-replacement hardware leave cracked tiles that leak during the next big storm. On a 1940s bungalow in Monte Vista, our crew found original wood-deck underlayment under concrete tile that needed evaluation before any racking went up. We plan for that from the first site visit.
  • Interconnection rejections from incomplete rapid-shutdown mapping. Pre-1960s bungalows in the 78201-78210 corridor often have detached garages with their own sub-panels. If the rapid-shutdown diagram omits that sub-panel, CPS Energy kicks the application back and your inverter sits dormant for weeks. We map every panel and sub-panel on day one.
  • Hail-damaged panels with hidden microcrack degradation. A panel can survive a 1.5-inch hail impact with no visible glass damage and still lose 10 to 15 percent output from microcracks. San Antonio sits in a high-frequency hail corridor, so we recommend panels with strong IEC 61215 hail-impact ratings and we document post-storm production drops.

Pricing for Solar Panel Installation in San Antonio, TX

Here are the line-item ranges for the work we do across San Antonio. These are honest starting points, not the inflated “list price” designed to make a discount feel generous.

Service Typical Range in San Antonio

What moves the number: roof pitch, tile versus shingle, historic-district design constraints, whether your main panel needs upgrading, and the CPS Energy export rate at the time of application. We quote off your actual bill, not a spreadsheet guess. Estimates are free. If a salesman needs an answer tonight, the answer is no. Call (877) 550-6892 and we’ll walk the roof with you.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"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 · Verified customer
★★★★★

"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 · Verified customer
★★★★★

"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."
