Fast, Reliable Commercial Solar Installation Across Hornsby Bend
Commercial solar installation in Hornsby Bend usually runs $85,000 to $450,000 before incentives for a system sized between 50 kW and 250 kW, and the payback math depends more here than almost anywhere else in Travis County on which side of the 78725 utility boundary your building sits on. That is not a small detail. It shifts your return by years, and we check it before we quote anything.
Gus’s Solar has been doing commercial work across Hornsby Bend long enough to know that a warehouse off FM 969 and an ag parcel south of the river require two completely different approaches. If you are tired of salesmen who cannot tell you whether you are on Austin Energy’s Value of Solar tariff or Oncor’s net metering, call us at (877) 550-6892. Bring a bill. We will bring the math.
Why Gus’s Solar Is Hornsby Bend’s Preferred Commercial Solar Installation Company
We are not a pop-up crew working this ZIP code for a season. Gus Petrakis founded this company in 2011, put his name on the truck, and has been quoting year-25 production numbers off actual utility bills ever since. When a Hornsby Bend business owner calls our office, a live person answers. Not a ticketing portal, not a call center three states away. That matters when your inverter throws a fault at 7 a.m. on a Tuesday and you need someone who knows your roof.
The team at Gus’s Solar does our own work. Background-checked, uniformed technicians install every panel, torque every bolt, and flash every penetration themselves. We do not hand commercial jobs off to subcontractors. If a building owner in Hornsby Bend has a question about their system two years after commissioning, they call the same number and talk to the same people who did the original survey.
Response time to Hornsby Bend is typically same week for site surveys and two to three weeks for most commercial installs, depending on permitting jurisdiction. And our 90-Day Done Right Promise is in writing on every job. If it is not right, Gus makes it right. One call brings him back.
Our Commercial Solar Installation Services in Hornsby Bend
Our Commercial Solar Installation work in Hornsby Bend covers everything from small retail rooftops to multi-acre ground-mount arrays. Here is what we handle most often in the 78725.
Commercial Rooftop Solar
Flat commercial roofs along FM 969 and the industrial pockets near the Hornsby Bend Biosolids plant are prime candidates for rooftop solar, but the cottonwood and willow seed drift from the Colorado River bottomland is real. We spec enhanced soiling mitigation on flat roofs here, because accumulated seed matter can knock 5 to 10 percent off your annual kWh production if it is not addressed. A typical 100 kW commercial rooftop system in Hornsby Bend runs $125,000 to $180,000 before Federal Investment Tax Credit.
Agricultural & Ground-Mount Solar
Hornsby Bend still has working agricultural land, and many parcels are large enough that east-west split ground-mount arrays make more sense than rooftop. These systems give you better morning and afternoon production curves, which often matches irrigation pump and shop loads better than a south-only orientation. A 50 kW ground-mount on open Hornsby Bend acreage typically runs $85,000 to $130,000, though site preparation and trenching distance to your meter can move that number either direction. Before we design anything, we confirm whether your address falls under Travis County ETJ permitting or City of Austin rules, because the process and inspection timeline are not the same.
Commercial Battery Storage
For Hornsby Bend businesses, storage decisions hinge on your utility tariff. If you are on Austin Energy’s Value of Solar tariff, the fixed per-kWh production credit changes the storage calculus entirely versus Oncor net metering, where shifting your export to evening hours is the whole game. A 30 kWh commercial battery bank with Enphase or FranklinWH equipment typically adds $28,000 to $45,000 to a project. We will run the numbers both ways before you spend a dollar.
Solar Carport Installation
Carports work well on Hornsby Bend commercial lots that are already paved and unshaded. They give you covered parking and production without touching an aging roof membrane. A 30-space commercial carport array usually falls between $110,000 and $175,000 depending on steel requirements and utility interconnection constraints.

Trusted Brands We Service in Hornsby Bend
We work with Qcells and REC panels, SunPower for high-production roof conditions, and SolarEdge and Enphase for inverter and monitoring hardware.

If a panel or optimizer fails under warranty, we handle the RMA and the replacement. You do not chase the manufacturer.
Common Commercial Solar Installation Problems We See in Hornsby Bend Homes
- Wrong utility tariff assumption. This is the big one in Hornsby Bend. A building at a 78725 address on the Oncor side of the line gets quoted as if Austin Energy’s Value of Solar applies, and the owner’s first true-up statement is a rude awakening. We verify territory before we quote, not after.
- Permit jurisdiction confusion. Many commercial parcels in the 78725 area fall under Travis County ETJ rather than City of Austin permitting. If a contractor pulls the wrong permit, the rejection can cost you an entire season.
- Soiling and seed drift on flat roofs. Cottonwood and willow seed from the river corridor settles on flat commercial rooftops and clogs heat sinks on microinverters. Without a maintenance schedule, production degrades quietly.
- Electrical service capacity limitations. Older rural structures and converted agricultural buildings in Hornsby Bend often have 200-amp or smaller services that cannot accommodate a large commercial array without a panel upgrade. We identify that on the first site visit, not halfway through the install.

FAQs - Commercial Solar Installation in Hornsby Bend
How do I know if my Hornsby Bend commercial building is on Austin Energy’s Value of Solar tariff or Oncor’s net metering rules?
Pull your most recent electric bill and look at the utility name at the top. If it says Austin Energy, you are on the Value of Solar tariff, which pays a fixed per-kWh production credit regardless of how much you self-consume. If it says Oncor with a retail electric provider, you are under Texas competitive market net metering rules, where export credits work differently. If you are not sure, call (877) 550-6892 with your bill in hand and we will tell you in two minutes. The payback math is not close between the two, so this is the first thing we check.
Do Travis County ETJ rules require any special wind-load documentation for a commercial solar array in Hornsby Bend?
Yes. Commercial arrays in Travis County ETJ, which covers many Hornsby Bend parcels, require engineered wind-load calculations stamped by a Texas-licensed professional engineer. The county’s wind speed design rating applies to both rooftop and ground-mount systems. We provide sealed engineering documents as part of every commercial quote. We never submit a permit package without them.
What’s a realistic degradation rate for panels on a flat commercial rooftop near the Hornsby Bend Biosolids plant, and how does soiling affect it?
Qcells and REC panels carry a 0.5% annual degradation rate, so year-25 output is around 87 to 88 percent of day-one nameplate. Soiling from cottonwood and willow seed drift near the Colorado River bottomland is separate from degradation, and it can suppress annual production an additional 5 to 10 percent on a flat roof if the array is never cleaned. We specify the cleaning interval in every Hornsby Bend commercial proposal.
Can I install a ground-mount solar array on agricultural land in Hornsby Bend without Austin city permits?
If your parcel falls under Travis County ETJ, you do not need a City of Austin permit, but you do need a Travis County permit and potentially a floodplain review if the site is in the Colorado River bottomland. If your address is inside the Austin city limits even though the ZIP is 78725, Austin permitting applies. This is exactly why we verify jurisdiction before we survey. It saves weeks.
How does the Value of Solar tariff affect my commercial battery storage decision in Hornsby Bend?
On Austin Energy’s Value of Solar tariff, your solar production earns a fixed per-kWh credit regardless of when you use it, so batteries have less arbitrage value. On Oncor’s net metering with a competitive provider, storing midday solar and exporting it in the evening can dramatically improve your return. We model the battery decision against your actual bill and tariff. If the storage does not pay, we tell you that before you spend $30,000 on it.
