AfterFast, Reliable Solar Battery Storage & Backup Across Georgetown
Solar battery storage in Georgetown, TX typically costs between $11,000 and $18,500 installed, depending on whether you’re adding a single Tesla Powerwall 3, pairing two Enphase IQ batteries, or retrofitting storage onto an existing array. Most Georgetown homeowners we work with get their system sized, permitted through Georgetown Utility Systems, and installed within three to four weeks. If your lights are flickering during spring storm season or your summer Oncor bill (or GUS bill, more accurately) has you rethinking your energy setup, call Gus at (877) 550-6892 and he’ll walk you through the math off your actual usage, not a brochure estimate.
We work throughout Georgetown, from Sun City’s quiet cul-de-sacs to the acreage properties off Ronald Reagan Boulevard and the newer master-planned communities along I-35. Gus’s Solar is the local, owner-operated outfit that shows up with a name on the truck and a real answer to the question: what happens when the grid goes down in August?
Why Gus’s Solar Is Georgetown’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started Gus’s Solar in 2011, put his name on the door, and has spent over 29 years in the trades serving local communities. When you call our office, a live person answers. Not a routing tree. Not a call center in another state. That matters when a spring hailstorm knocks out power in Teravista and you need to know whether your battery is doing what it’s supposed to do that night, not next Tuesday.
Georgetown homeowners tell us the same story repeatedly: a door-knocker quoted one number, the finance guy called with a bigger one, and the crew that showed up was subcontracted from two counties over. We don’t work that way. Gus quotes the year-25 output, not the day-one brochure number, and the price he writes down is the price you pay. No signature wanted tonight. Take two weeks. Think about it. The price will be the same.
Every battery install in Georgetown gets the 90-Day Done Right Promise in writing. If it isn’t right, Gus makes it right, and one call brings him back. His own background-checked, uniformed crew does the work. No subs. No mystery trucks in your driveway.

Our Solar Battery Storage & Backup Services in Georgetown
Tesla Powerwall Installation
A Tesla Powerwall 3 installed in Georgetown runs between $12,000 and $16,000 before federal tax credits, including the Gateway and permitting. We size Powerwalls against your actual GUS interval data, not square footage. In Sun City Georgetown, where single-story ranch homes run two AC zones from April through October, a single Powerwall 3 usually covers essential circuits and one AC unit overnight. For true whole-home coverage on a 2,400-square-foot Georgetown home, expect to pair two units. Gus’s crew is factory-trained on Tesla equipment and we handle the full GUS interconnection application for battery storage, which is a separate filing from a solar-only permit.
Enphase IQ Battery Installation
Enphase IQ Battery 5P units make sense for Georgetown homes with existing Enphase microinverter arrays, and they’re modular, so you can start with one and add a second or third later. Expect to pay between $5,500 and $9,000 per 5P unit installed, with the Gateway and commissioning included. The IQ Battery’s chemistry holds up well in the heat, which matters when your garage hits 105°F in August and the battery is mounted on the south wall.
Whole-Home Backup Power
Whole-home backup in Georgetown is a different animal than it was five years ago. The grid here is generally reliable, but the I-35 hail corridor means outage risk doesn’t come from rolling blackouts so much as storm damage to distribution lines. A properly sized whole-home system for a Wolf Ranch or Parkside on the River home starts around $18,000 and goes up from there, depending on how many tons of AC and whether you have a pool pump, well pump, or electric water heater. We’ll bring a load calculator, not a sales slide, and tell you honestly if your home needs two Powerwalls or if one plus a critical-loads panel does the job.
Battery Retrofit for Existing Solar
If Georgetown Utility Systems already cut your interconnection approval on a solar array and you’re now watching April and May true-up statements wipe out your credits, a battery retrofit is the answer. Adding an Enphase or FranklinWH battery to an existing array runs $9,000 to $14,000 in Georgetown, and it changes how your system behaves during peak-rate windows. We recently retrofitted an Enphase IQ Battery onto a 2019 south-facing array in Sun City Georgetown that the HOA required be hidden from the street. We sized the backup for the homeowner’s two AC zones and medical equipment, then walked the interconnection application through GUS’s single municipal desk in one trip. After the first summer, the true-up statement showed a 92% kWh offset. That’s the kind of result you get when the installer knows this utility’s rules.

Common Solar Battery Storage & Backup Problems We See in Georgetown Homes
- Undersized batteries for summer AC loads. A battery sized off the winter bill works fine in January and dies at 2 a.m. in July. Georgetown’s summer cooling loads run 40-60% above annual average, and we see this mismatch constantly in Wolf Ranch and Parkside on the River.
- HOA visibility rules in Sun City Georgetown. The CC&Rs in Sun City prohibit panels visible from the street, and many homes have north-facing front elevations. An installer who doesn’t run production models first can put the whole array on a compliant slope that yields 15-20% less annual output, leaving the battery undersized.
- Hail damage to inverters and enclosures. Georgetown sits in the hail corridor, and golf-ball-sized hail off Ronald Reagan Boulevard can crack inverter enclosures if the equipment isn’t rated for impact. Class 4-rated panels are standard for us, but the inverter and battery mounting hardware need the same scrutiny.
- Wrong true-up model on the ROI quote. If your battery payback was calculated on an ERCOT retail plan instead of Georgetown Utility Systems’ council-set net-metering tariff, the number is wrong. We pull your actual GUS usage data and build the math off what this utility actually pays and charges, which changes the timeline by years in some cases.
Pricing for Solar Battery Storage & Backup in Georgetown, TX
A single Enphase IQ Battery 5P installed on an existing Georgetown array runs $5,500 to $9,000. A single Tesla Powerwall 3 with Gateway runs $12,000 to $16,000. A whole-home system with two Powerwalls or two-to-three IQ Batteries on a 2,000-3,000 square foot home in Georgetown starts at $18,000 and can reach $28,000 depending on load profile and panel location. The federal Investment Tax Credit currently covers 30% of system cost, and Georgetown Utility Systems does not impose additional battery-specific fees. What changes your number: the age and size of your existing array, whether your electrical panel needs work, how far the battery sits from your main panel, and whether you want whole-home or critical-loads backup.

FAQs - Solar Battery Storage & Backup in Georgetown
GUS sets its own buyback rate by City Council vote, not by ERCOT market rules, so what you get paid for excess solar production is a local political decision that can change with an election. A battery changes the math because you stop selling cheap solar at noon and buying expensive power at 7 p.m. Instead, you store your own production and use it during peak hours. In Georgetown, that value gap is set by whatever tariff the Council currently approves, and it’s narrower than what Oncor customers see in Round Rock. We’ll run your battery ROI off the current GUS tariff, not a generic ERCOT model, so the payback number you see is real. Call (877) 550-6892 and we’ll build the math together.
Yes, and it’s done routinely. The panels must go on a roof plane not visible from the street, which in Sun City Georgetown often means the rear elevation or a courtyard-facing slope. What matters for the battery is that the array’s annual production still covers your storage needs. Our crew runs production models before any contract is signed, using the actual compass orientation and pitch of your compliant roof planes, so you know exactly how many kWh a year that hidden array will generate before you buy a battery. Call us and we’ll look at your specific lot before you sign anything.
You need a separate application. GUS treats battery storage as its own interconnection filing, even if your solar array is already approved and running. Gus’s team handles the full battery application through GUS’s single municipal desk, and we’ll tell you upfront what paperwork the utility wants, what the approval timeline looks like, and whether your existing solar approval needs any amendment. No surprises. Call (877) 550-6892 and we’ll walk your specific application through.
Hail is a real risk in Georgetown, and while batteries are usually mounted on a garage wall or exterior wall (not the roof), inverters and rooftop DC wiring are exposed. We specify Class 4 impact-rated panels as standard in Williamson County, not as an upsell, and we mount inverters and battery enclosures where they get structural protection rather than bolt them onto the first empty wall. Losing an inverter to golf-ball hail off a spring supercell is not covered by every manufacturer warranty, so we don’t gamble with it.
For a typical 2,200-2,800 square foot home in Wolf Ranch, Parkside on the River, or Teravista with two AC zones and standard electric appliances, you’re looking at two Tesla Powerwalls or three Enphase IQ Battery 5P units to cover the whole home overnight. One Powerwall or two IQ Batteries will run critical loads (fridge, lights, medical equipment, one AC unit) but won’t carry everything. We’ll pull your actual usage history and run the load calculation before we recommend a number. Free estimate, no pressure. Call (877) 550-6892.
