AfterFast, Reliable Solar Battery Storage & Backup Across Flower Mound
If you live in Flower Mound and you’re tired of watching your solar panels sit idle when the grid goes down, battery storage changes that. A properly sized battery captures the power your system makes during the day and keeps your lights, fridge, and outlets running through outages and the Oncor peak-rate window. Gus’s Solar installs and servs Solar Battery Storage & Backup systems throughout Flower Mound, from Wellington to The Preserve, with a live person answering the phone 24/7 at (877) 550-6892.
And here’s the thing most Flower Mound homeowners don’t hear from the door-to-door crowd: your mature post oaks are protected. You can’t trim your way to more panel output. Battery storage becomes the real solution, which we’ll get into below.
Why Gus’s Solar Is Flower Mound’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 and never handed the work to a sub. The crew that shows up at your Flower Mound home is Gus’s crew, background-checked and uniformed, and Gus himself answers his phone. That’s rare in solar, and people in master-planned neighborhoods like Chinn Chapel and Wellington notice the difference.
We’ve worked on homes across Flower Mound for years, and we know the housing stock: big brick-front executive homes from the 1990s through 2010s, 3,000 to 5,500 square feet, with those multi-plane rooflines that look great from the street but split usable solar space into awkward pockets. We design battery systems around that reality, not around a software rendering.
The 90-Day Done Right Promise applies to every battery job we do in Flower Mound. If it’s not right, one call brings Gus back. That’s in writing. And our L.O.C.A.L. code of operation means Local roots, On time, Community first, Accountable, and Loyal. We quote a price off your actual utility bill, not a brochure. Take two weeks to think about it. The price will be the same.
Our Solar Battery Storage & Backup Services in Flower Mound
Battery Retrofit for Existing Solar
Most of the calls we get in Flower Mound are from homeowners who bought solar years ago and now realize their panels don’t help when the power goes out. Your system likely has a grid-tied inverter that shuts down automatically during an outage for safety. We retrofit batteries onto existing systems all the time, even older inverters from the mid-2000s that original installers walked away from. If your original installer is gone, that’s fine. We can still add storage.
Time-of-Use & NEM 3.0 Optimization
Oncor’s 4 to 7 p.m. peak window is where Flower Mound solar owners bleed money. Your panels make power at noon when rates are low, but you come home and use power at 6 p.m. when rates spike. A battery configured correctly charges during cheap midday solar or overnight grid rates, then discharges during peak, so you’re not buying back expensive kilowatt-hours. This matters more today than it did five years ago, and most systems in Flower Mound are not configured for it.
Whole-Home Backup Power
Flower Mound sits in the North Texas hail corridor, and spring supercells coming off Lake Grapevine knock out grid power for hours at a time. If your battery is sized only for rate arbitrage, it won’t carry your AC through an outage. We size whole-home backup around what you actually need to run: AC compressor, fridge, medical equipment, home office. We test the full transfer under load before we leave your driveway.
Tesla Powerwall Installation
The Powerwall 3 is the most common battery we install in Flower Mound, and for good reason: it pairs well with older and newer solar systems, and the built-in inverter simplifies retrofit jobs on multi-plane rooflines. We’re a certified installer, and we don’t outsource the wiring or the programming.
Enphase IQ Battery Installation
If your Flower Mound home already runs Enphase microinverters, the Enphase IQ Battery is usually the cleanest path. The system communicates natively, which means fewer compatibility workarounds and a cleaner monitoring dashboard. For homes in The Preserve or along Bridlewood with complex array splits, the per-panel visibility Enphase gives you is genuinely useful.

Trusted Brands We Service in Flower Mound
We work with the equipment brands that hold up in North Texas heat and hail: Tesla, Enphase, SolarEdge, and FranklinWH. We keep common components stocked for Flower Mound customers, which means faster turnaround when a battery inverter or communication module fails. If your system uses one of these brands and you’re getting error codes or reduced capacity, call us. We don’t tell you to call the manufacturer and wait on hold.
Common Solar Battery Storage & Backup Problems We See in Flower Mound Homes
- Satellite-shaded design that missed the real canopy. Google’s imaging last passed over parts of Wellington and Chinn Chapel years ago. Satellite tools show a clear south roof; in reality, a 25-year-old post oak has closed over the array. Production estimates run 20 to 30 percent high, and the battery never charges from solar the way the proposal promised. We do a physical site visit before quoting, always.
- Batteries that never pull grid power when they should. On shade-limited Flower Mound lots, a battery often needs to charge from the grid during cheap overnight hours to discharge during Oncor peak. Poorly configured systems just sit there, nearly empty by 4 p.m., and the homeowner sees no bill savings.
- Backup sized for arbitrage, not for outages. Hail season in Flower Mound regularly knocks out power for hours. If your battery was sized to shift TOU load only, it won’t run your AC through the kind of outage that scares people the most. We see this gap in homes across 75022 and 75028.
- Builder-grade solar with no storage and no support. A lot of 2010s Flower Mound executive homes were built with a small solar array and zero battery, installed by whomever the builder contracted. Those companies are long gone. We take over these orphaned systems and add storage that actually works with the existing inverter.
Pricing for Solar Battery Storage & Backup in Flower Mound, TX
For a Flower Mound home, a single Tesla Powerwall 3 retrofit typically runs $13,500 to $16,800 installed, depending on your inverter compatibility and whether we need a backup gateway replacement. An Enphase IQ Battery 5P addition usually lands between $8,900 and $11,500. Whole-home backup with two Powerwall 3 units and a smart load panel generally runs $26,000 to $31,000 in Flower Mound, and the larger homes off Morriss Road or in Tour 18 sometimes need a three-battery configuration, which pushes the range to $38,000 to $44,000.
What changes the price in Flower Mound specifically? Your existing inverter age, whether your main panel is 200 amp or needs an upgrade, and how much shade means we need to oversize the battery relative to the array.

FAQs - Solar Battery Storage & Backup in Flower Mound
Yes, and battery storage is actually the strongest move when shading limits your panel output. Flower Mound’s Urban Forest Management Plan protects mature post oaks and bur oaks so strictly that you can’t legally trim or remove canopy trees to improve solar exposure. That means your array’s production is fixed at whatever the trees allow. A battery charges from whatever solar you do produce, and when that’s not enough, a correctly configured system draws from the grid during cheap overnight hours and discharges during Oncor’s 4 to 7 p.m. peak. You still cut your bill meaningfully. Call (877) 550-6892 for an exact quote on your home’s shade profile.
Flower Mound is served by Oncor, not a municipal utility, so your buyback rate for excess solar is far below what you pay when you pull from the grid at night. That’s a fact, not fine print. Net metering in its traditional 1-to-1 form is essentially gone here, which means every kilowatt-hour you store and use yourself is worth more than every kilowatt-hour you export. A battery shifts your solar generation into the hours when grid power costs you real money, and that’s where the payback comes from. In Flower Mound, a well-sized single Powerwall 3 typically pays for itself in 7 to 9 years on TOU bill savings alone.
In most cases, yes. The mid-2000s inverters we see across Flower Mound’s 75022 and 75027 subdivisions are generally AC-coupled, which means a modern battery system can sit alongside them without replacing the inverter. There are edge cases: some older Fronius and SMA inverters need a frequency-watt adjustment firmware update, and a few legacy string inverters are simply too old to communicate with a Powerwall 3’s gateway. We test compatibility during a site visit before we quote you a number. No surprises, no re-quote after the fact.
Yes, if it’s sized for it. A single Powerwall 3 or IQ Battery 5P will run a modern variable-speed AC unit for a few hours. A 4-ton single-stage compressor on a hot May afternoon when the grid goes down is a bigger ask; that typically needs at least two Powerwalls to start and run reliably. We size backup systems using your actual equipment nameplate data, not a generic square-footage table. During hail-outage season, when power is out for many hours, the last thing you want to discover is that your battery can’t start your compressor. We test that before we leave.
Yes. This is one of the most common jobs we do in Flower Mound. Builders and door-to-door national outfits installed solar across neighborhoods like Wellington, The Preserve, and Chinn Chapel during the 2010s, and a large share of those companies no longer exist. If your original installer is gone, that doesn’t strand your equipment. We take over the system, inspect the wiring and inverter, and add battery storage that works with what’s already on your roof. Often the existing array is perfectly fine; it just needs a new inverter gateway and a battery. Call (877) 550-6892 and ask for a system takeover assessment.
