Gus Petrakis has kept his name on every job since 2011. We know Hornsby Bend’s split utility territory, we know the ETJ permit process, and we won’t quote you a battery system based on math that doesn’t apply to your address.
Why Gus’s Solar Is Hornsby Bend’s Preferred Solar Battery Storage & Backup Company
Hornsby Bend sits in a strange spot on the map. Some homes in 78725 get their power through Austin Energy’s Value of Solar tariff. Others are on Oncor’s distribution network with a retail electric provider. That single difference changes what a battery is worth to you, and most installers don’t bother checking before they hand you a proposal. We do. It’s the first thing we verify on every battery job in Hornsby Bend.
Gus’s own crew does the install. No subs, no day-labor crews, no strangers on your property. We’re background-checked, uniformed, and we’ve been showing up on time in this area for over a decade. Our Solar Battery Storage & Backup work comes with the 90-Day Done Right Promise in writing: if it’s not right, Gus comes back and makes it right. One call brings him to your door.
We answer the phone. At 2 a.m. during a July thunderstorm when your battery’s throwing a fault code, you get a live person who can actually help. Not a ticket number. Not a call center three states away. That matters more than people realize until it’s 2 a.m. and the power’s out.
Our Solar Battery Storage & Backup Services in Hornsby Bend
Tesla Powerwall Installation
A single Tesla Powerwall 3 installed in Hornsby Bend typically runs $14,000 to $17,500 before incentives. Two Powerwalls for whole-home backup on one of the larger acreage lots near the river usually lands between $26,000 and $31,000. We handle the full install, including the gateway and any panel work your older home needs to pass Travis County ETJ inspection.
Enphase IQ Battery Installation
The Enphase IQ Battery 5P is a good fit for Hornsby Bend homes with existing Enphase microinverter systems. We configure these for storm backup and time-of-use savings, and we’ve installed enough of them here to know exactly how the humidity near the Colorado River affects their thermal behavior. Expect $10,500 to $14,800 for a single IQ Battery with commissioning, depending on your existing inverter setup.
Whole-Home Backup Power
If you’re on a well and lose power every time a good storm rolls through the bottomland, whole-home backup is what actually solves the problem. We size the battery bank to your actual load profile: well pump, septic, HVAC, refrigeration. For most Hornsby Bend homes that means two to three batteries and a smart load panel. Budget $24,000 to $38,000 depending on whether we need to replace your main panel.
Battery Retrofit for Existing Solar
Plenty of Hornsby Bend homeowners put in solar years ago, before batteries made financial sense here. Retrofitting a battery onto an existing array is our most common job in 78725. The catch: older systems often have outdated rapid shutdown modules that fail Travis County ETJ inspection. We check that before we quote, so you’re not surprised mid-permit. Typical retrofit cost: $12,000 to $16,500 with one battery, all panel work included.

Trusted Brands We Service in Hornsby Bend
We work with the equipment we’d put on our own homes: Tesla, Enphase, and FranklinWH are the three we recommend most often in Hornsby Bend, with SolarEdge as a strong option for specific retrofit situations. We keep common replacement components in our local truck stock, so a failed communication module or a clogged fan doesn’t leave you waiting two weeks on a parts shipment from California. If something breaks, we fix it fast.
Common Solar Battery Storage & Backup Problems We See in Hornsby Bend Homes
- Cottonwood seed clogging ventilation intakes. The river canopy sheds cottonwood and willow seed every spring, and that fine material finds its way into battery cooling vents. During summer storms, a clogged intake causes thermal throttling, where the battery deliberately reduces output to protect itself. We clean and screen the intakes as part of our Hornsby Bend installs.
- Incorrect tariff configuration draining battery savings. Homes on the Austin Energy side of the service boundary see true-up statement credits fall off when the battery isn’t calibrated for the Value of Solar tariff. A battery that’s programmed for net metering math does the wrong things on the VoS tariff. We set the software to match your actual utility, not a template.
- Panel and rapid shutdown failures blocking permits. Older rural homes in Hornsby Bend often have solar installed before current rapid shutdown codes. When you add a battery, the whole system gets re-inspected under today’s rules. If the old modules don’t comply, Travis County ETJ won’t sign off. We flag this on day one and fix it during the same job.
- Ground-mount arrays on large lots without battery integration. Open acreage makes east-west split ground mounts popular in Hornsby Bend, but many were built without any thought of storage. Adding a battery to a ground-mount system means running conduit, upgrading the inverter, and sometimes reconfiguring string wiring. It’s doable, and we’ve done it many times here, but it’s not a two-hour bolt-on job.

FAQs - Solar Battery Storage & Backup in Hornsby Bend
You can check your electric bill for the utility name, but even that sometimes misleads because delivery charges and generation charges can come from different entities. The reliable way is to let us check the exact meter number. We pull the interconnection record and confirm your tariff structure before we put a single number in front of you. This takes about twenty minutes and it’s free. Call (877) 550-6892 and we’ll sort it out.
Yes, if the system is sized correctly. A 240V well pump draws a hard startup surge, which means the battery’s inverter needs enough headroom to handle it. We calculate that spec against your pump’s exact rating before we recommend a battery. Most Hornsby Bend well pumps need at least a 5kW continuous inverter rating, which rules out some smaller battery options. We’ll tell you plainly which ones will work and which won’t.
Yes, and this catches people off guard. Many Hornsby Bend addresses fall under Travis County ETJ permitting, not City of Austin permits. The forms are different, the inspection schedule is different, and the rapid shutdown requirements get applied more strictly because the county inspector is reviewing older rural equipment against current code. We know the ETJ process and we pre-check your existing system so the permit doesn’t stall. Most Hornsby Bend battery permits clear in two to four weeks when the paperwork is right.
Yes, absolutely. East-west split arrays are common on the larger lots here, and they actually pair well with batteries because they produce power earlier and later in the day, stretching your usable window. The retrofit means running conduit from the ground-mount location to your battery placement point, which is usually near the main panel on the house. Budget for that trenching work in addition to the battery itself.
Because you’re likely on different sides of the Hornsby Bend utility boundary. One address in 78725 might be on Austin Energy’s Value of Solar tariff, where the battery’s main job is self-consumption during peak pricing windows. The next address over might be Oncor with a retail provider that pays export credits differently, making the battery’s value mostly about outage protection and demand charge avoidance. Same street, same ZIP code, completely different math. We’ll show you the year-25 numbers for your actual meter, not a brochure average. Call (877) 550-6892 for the real picture.
Battery Work That Fits Hornsby Bend’s Reality
Hornsby Bend is not a clean little suburb where every house is the same. You’ve got older rural homes on acreage, manufactured homes that were built before anyone thought about energy storage, and scattered new construction pushed east from Austin. The split between Austin Energy’s Value of Solar tariff and Oncor’s retail providers means the same battery can have completely different payback periods within the same 78725 ZIP code. That’s the first thing we check on every job here, and it’s the reason you shouldn’t take battery advice from someone who doesn’t know this specific patch of Travis County.
On a large acreage lot in Hornsby Bend’s ETJ, we retrofitted an Enphase IQ Battery onto an existing ground-mount array after an Oncor interconnection check revealed the homeowner was on a retail plan without net metering. Our crew configured time-of-use optimization, and the system now shaves peak charges while providing whole-home backup during Colorado River bottomland storms. That job only worked because we checked the utility boundary before the quote. If we’d assumed Austin Energy, the whole proposal would have been wrong.
Hornsby Bend’s position in the floodplain bottomland brings a specific set of problems for battery equipment. The humidity hangs around longer here than it does up on the dry ridges, and the cottonwoods and willows along the river bends drop seed material every spring. That fine drift finds its way into battery ventilation intakes and causes thermal throttling when the equipment needs to shed heat the most, which is exactly when summer storms hit. We screen and seal the intakes on every Hornsby Bend install. It’s a small thing that prevents a lot of middle-of-July service calls.
The biosolids plant and surrounding agricultural land mean many residential parcels here are large and unshaded. East-west split ground mounts are genuinely popular, and they work well with battery storage. But many of those addresses fall under Travis County ETJ permitting rather than City of Austin. Confirm jurisdiction before pulling a solar permit. We do that verification as step one. The inspection timeline and application forms are different enough that guessing wrong adds weeks to a project.
If you’re on the Austin Energy side of the boundary, your true-up statement credits drop when your battery isn’t calibrated for the Value of Solar tariff. That’s not a hardware problem. It’s a configuration problem. We set the software to match your actual tariff, so the battery charges and discharges at the right times for the VoS math. A battery that’s programmed for net metering does the wrong things on the VoS tariff, and you’ll see it on your true-up statement a year later. We fix that from day one.
