Fast, Reliable Solar Battery Storage & Backup Across Little Elm
When a spring storm drops hail the size of golf balls over Lewisville Lake, the power can flicker for hours in Little Elm. A solar battery keeps your refrigerator running, your well pump spinning, and your lights on while the neighborhood waits for the utility truck. Most battery backup installs in Little Elm run between $11,000 and $16,500 before any federal tax credit, and the team at Gus’s Solar can usually have yours running within two to three weeks of signing. If you’re tired of resetting clocks and wondering what’s in the freezer, call (877) 550-6892 and talk to a real person.
Why Gus’s Solar Is Little Elm’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis put his own name on the building, and he’s the one who answers when you call with a question about your battery’s state of charge. Homeowners around Little Elm tell us the same thing: the national outfits that canvassed their streets quoted one number on the phone and a different one at the kitchen table. That doesn’t happen here. We quote the year-25 output, not the day-one brochure number, and we’ll hand you the math based on your actual utility bill, not a generic estimate.
Our crew has installed battery systems in neighborhoods all around Little Elm, from the streets off Eldorado Parkway east of 423 to the newer builds near Light Farms. We know the local electric co-op and Oncor service territory quirks, and we know which home builders used 200-amp panels that leave clean room for a backup breaker. When you call, you get a live person 24/7, and when we schedule a visit, Gus’s crew shows up uniformed and background-checked. The 90-Day Done Right Promise applies to every battery install we do in Little Elm: if we didn’t get it right, we make it right, in writing.
Our Solar Battery Storage & Backup Services in Little Elm
Tesla Powerwall Installation
The Tesla Powerwall is the most requested battery we install in Little Elm. Most homes we see here do well with one Powerwall 3 for essential circuits or two for whole-home coverage, depending on whether you’re backing up a single AC unit or two. We handle the full install, including the gateway, electrical panel work, and app setup, and we’ll show you how to read your own monitoring screen before we leave.

Enphase IQ Battery Installation
If your existing solar runs on Enphase microinverters, the IQ Battery 5P slides into that system cleanly without a separate string inverter. This is common in Little Elm because a lot of the solar installed here in the last decade already uses Enphase hardware. We can match your existing system and add modular capacity over time if your needs grow.

Whole-Home Backup Power
For the lakefront properties along Lewisville Lake and the larger two-story homes near Paloma Creek, whole-home backup usually means two or three batteries and a smart load panel. We’ll map your critical loads and tell you straight up whether you actually need that much capacity or whether one battery with a critical-loads subpanel does the job for less. Nobody at Gus’s Solar is going to sell you more battery than your breaker panel can use.

Battery Retrofit for Existing Solar
A lot of Little Elm homes got solar between 2015 and 2020 and skipped storage because battery prices were higher then. Retrofitting a battery to an existing system is our most common request in the 75068 ZIP code, and most modern systems can be retrofitted without replacing your inverter. We’ll check your existing wiring, your panel rating, and your current inverter brand, then give you a fixed-price quote that doesn’t change before install day. While we’re out there, we can also set you up with Solar Panel Cleaning in Little Elm to get your production numbers back where they belong.

Common Solar Battery Storage & Backup Problems We See in Little Elm Homes
- Hail-damaged exterior connections – Denton County has seen multiple golf-ball-to-baseball hail years in the 2010s and 2020s, and the wiring harnesses and disconnect boxes on side walls take direct hits. We check every exterior connection for micro-cracking before we commission a battery.
- Builders who labeled breakers wrong – In fast-built subdivisions around Little Elm, the original electrical panel labeling is often off. Our crew re-maps your panel before wiring battery circuits so your backup actually covers what the label says it covers.
- Wrong battery sizing from online calculators – Generic online tools don’t account for a two-AC house in August. A lot of the calls we field are from Little Elm homeowners whose 10 kWh battery never stood a chance in July.
- Existing solar systems with no monitoring login – Plenty of people bought a house in Little Elm and inherited a solar system whose previous owner held the monitoring account. We can recover system access and link your battery controls so one app shows everything.
Pricing for Solar Battery Storage & Backup in Little Elm, TX
Budget these ranges for a turnkey install in Little Elm: a single Tesla Powerwall 3 typically runs $12,000 to $14,000 installed, an Enphase IQ Battery 5P around $8,500 to $11,000, and a FranklinWH aGate plus two aPower units between $16,000 and $19,500. Whole-home backup on a two-story 3,500-square-foot home near the lake usually lands in the $22,000 to $28,000 range before incentives. What moves the number: how many circuits you actually need backed up, whether your panel needs a new subpanel, and how far the battery sits from your main service entrance. The federal Investment Tax Credit currently covers 30% of battery system costs when the battery charges from solar, and we’ll help you file the paperwork. Getting a second quote? Good. Bring it to us. Gus offers a free second opinion on any written estimate, and the quote we give you won’t change while you take two weeks to think it over.

Little Elm doesn’t see California-style rolling blackouts, but the hail and wind storm season from March through June reliably knocks out power to scattered neighborhoods around the lake for hours at a time, and the 2021 winter storm showed what a multi-day grid failure looks like in North Texas. If you run medical equipment, work from home, or keep a stocked freezer, a battery buys you hours or days of normalcy while your neighbors wait it out.
Install prices in Little Elm run almost identical to neighboring cities; you might see a couple hundred dollars difference based on permitting fees and the exact install distance from our dispatch point. Any outfit quoting you wildly different numbers for “Little Elm pricing” versus “Frisco pricing” is playing games. Our number is our number, and it’s the same whether your street sign says Little Elm or Lake Dallas.
Every battery we install in Little Elm carries the manufacturer’s warranty, typically 10 years for Tesla Powerwall and Enphase IQ batteries when installed by an authorized installer, plus our own 90-Day Done Right Promise in writing. If something isn’t right in the first 90 days, Gus comes back and makes it right. No ticket number, no subcontracted repair crew, just the same team that put it in. Call (877) 550-6892 for a free estimate and a straight answer about what a battery system will actually do for your house on the north shore of Lewisville Lake.
