AfterFast, Reliable Solar Battery Storage & Backup Across Lewisville
Solar battery storage in Lewisville typically costs between $9,500 and $16,500 installed, and most jobs take one to two days. That’s the straight answer. The longer answer involves your panel, your roof, and which retail electric provider you’re signed up with – three things that matter more in Lewisville than almost anywhere else in the metroplex. We’ve been working on homes here long enough to know the difference. Gus’s Solar serves Lewisville homeowners with honest pricing, no-pressure quotes, and a live person who answers the phone at (877) 550-6892.
If you live in the older neighborhoods around Mill Street or down toward Corporate Drive, you already know your house has quirks. So do we. That’s why we quote battery jobs in Lewisville differently than we would in a brand-new subdivision up in Prosper. More on that below.
Why Gus’s Solar Is Lewisville’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 with a simple rule: put your own name on the truck and answer your own phone. That’s still how we operate. When a Lewisville homeowner calls about a Solar Battery Storage & Backup job, Gus or one of his crew picks up – not a call center, not a voicemail tree. You get a straight answer about whether a battery makes sense for your house, and if it does, what it’ll actually cost.
We’ve pulled old Zinsco panels out of ranch homes near the old downtown, installed Tesla Powerwalls in Castle Hills, and retrofitted batteries onto existing solar arrays all over the 75067 and 75077 ZIP codes. The reviews from Lewisville customers mention the same things: we showed up when we said we would, the price didn’t change, and when something needed attention, one call brought Gus back out. That’s the 90-Day Done Right Promise in writing on every job.
Being local means we don’t have to Google how long it takes to get from our DFW-area office to your street. We know. We also know what Oncor’s inspectors look for in Lewisville, which residential streets have the tightest transformer clearances, and how to schedule an interconnection that doesn’t stall your battery for three weeks.
Our Solar Battery Storage & Backup Services in Lewisville
Tesla Powerwall Installation
A Tesla Powerwall 3 installation in Lewisville runs $11,000 to $15,500 before any applicable incentives. That’s the most common battery we install here, and for good reason – it handles the July heat load on a 2,500-square-foot home without breaking a sweat. In Lewisville’s 75057 ZIP especially, we often pair a Powerwall with a panel upgrade to 200 amps, which we’ll flag in the quote so there’s no $3,000 surprise mid-job.
Enphase IQ Battery Installation
The Enphase IQ Battery 5P is a strong fit for Lewisville homes that already have Enphase microinverters on the roof. It’s modular, so you can add storage incrementally as your budget allows. Installations in Lewisville typically land between $9,500 and $13,000 for the first unit. If your existing system is Enphase-based, this almost always wires in more cleanly than a mixed-brand setup.
Whole-Home Backup Power
Whole-home backup in Lewisville means sizing a battery bank to carry your air conditioner, refrigerator, and well pump (yes, plenty of homes on the outer edges of 75077 still run on wells) through an outage. Most Lewisville homes need two batteries for true whole-home coverage, which puts the project in the $22,000 to $32,000 range. But many customers start with one battery and selective-load backup – protecting the fridge, lights, and a window unit – then expand later. We’ll show you both options with real math off your actual electric bill.
Battery Retrofit for Existing Solar
Plenty of Lewisville homeowners put solar on the roof back when net metering was simpler, and now they’re watching their export credits shrink. A battery retrofit lets you store that daytime production instead of sending it to the grid for pennies. We’ve retrofitted batteries onto systems installed as far back as 2011, including relocating AC disconnects and upgrading the rapid-shutdown labels Oncor requires. Retrofit pricing in Lewisville runs $10,000 to $14,500 depending on your inverter and whether your combiner box needs rework.

Trusted Brands We Service in Lewisville
We install and service batteries from Tesla, Enphase, FranklinWH, and Panasonic, and we keep common parts – Enphase combiners, Tesla gateway boards, Franklin aGate components – stocked in our DFW-area shop so Lewisville customers aren’t waiting on a shipment from California. If your existing battery is a Panasonic EverVolt or a FranklinWH aPower, our crew works on it without subbing the job out. Gus’s own people install it, flash every roof penetration, and stand behind the work.
Common Solar Battery Storage & Backup Problems We See in Lewisville Homes
- Fire-hazard panels that predate the battery. In the older 75057 neighborhoods around historic downtown, we still find Federal Pacific Stab-Lok and Zinsco panels that have been quietly feeding homes since the Carter and Reagan administrations. Oncor’s interconnection rules legally require a panel replacement before any battery or solar can go live. If a quote doesn’t mention this, the installer hasn’t looked at your house.
- Battery installs on undersized or vintage bus bars. A backfeed breaker on a 1970s-era panel can arc or overheat during a grid-down test if the bus bar isn’t rated for it. This is common in Lewisville homes built before 1985. We check the panel’s sticker before we ever quote the job, so the number we give you is the number you’ll pay.
- Choosing the wrong retail electric provider. Lewisville sits in Oncor’s deregulated territory, which means you pick your REP. Sign up with a provider that has no solar-buyback plan, and your Powerwall’s stored energy gets credited at avoided-cost rates – a fraction of what a good buyback plan pays. We’ll tell you which providers in the Oncor footprint actually compensate battery discharge fairly.
- Unprotected outdoor equipment in the hail corridor. Lewisville sits in the North Texas hail corridor, and a Schneider or Enphase combiner box mounted on an exposed south wall takes a beating. A cracked enclosure after the first spring storm is a warranty claim and a service call you don’t need. We specify hail-rated enclosures and mount hardware accordingly from the start.
Pricing for Solar Battery Storage & Backup in Lewisville, TX
A single battery installation in Lewisville runs $9,500 to $16,500, depending on brand, capacity, and whether your electrical panel needs upgrading. The panel upgrade question is the big variable here – in the 75057 ZIP, about two-thirds of the homes we quote need a 200-amp service upgrade before interconnection, which adds $2,000 to $3,500. In the newer 75067 and 75077 subdivisions, that’s less common, but roof age (20-30 years on many 1990s-era tract homes) sometimes triggers a re-roof conversation. We give you a written quote that breaks out every line item, and we honor it. Bring us a bill, Gus will bring you the math. Call (877) 550-6892 for a free estimate – take two weeks to think about it. The price will be the same.

FAQs - Solar Battery Storage & Backup in Lewisville
Because a large share of Lewisville homes – especially in the 75057 ZIP built out in the 1970s and 80s – still have 100-amp electrical panels, many of them Federal Pacific Stab-Lok or Zinsco brands that are documented fire hazards. Oncor will not approve a battery interconnection on a panel like that, and neither will we. The panel replacement adds $2,000 to $3,500 to the job, but it’s not optional. Any quote that omits it either hasn’t looked at your panel or is planning to surprise you later. Call (877) 550-6892 if you want us to check yours – we’ll tell you straight what it’ll take.
The short answer is that several REPs operating in Oncor’s territory offer solar-buyback plans with retail-rate credits for exported battery energy, but the plan names and rates change frequently – so we check the current offerings every time we quote a job. What we won’t do is name a single provider as the best and send you off without verifying today’s terms. Part of our battery install includes sitting down with your actual usage history and comparing buyback plans line by line, so your stored energy earns retail credit instead of avoided-cost pennies.
Most wall-mount batteries like the Tesla Powerwall and FranklinWH aPower are rated for outdoor installation and built to handle most hail, but the combination of North Texas hail frequency and spring storm winds makes enclosure choice and mounting location matter. We specify hail-rated conduit covers, protective bollards where a vehicle could back into the unit, and mounting heights that keep the battery clear of pooling water and flying gravel. If your HOA allows, a shaded north-facing wall also reduces thermal derating, which matters in Lewisville’s 100-plus-degree July afternoons.
Yes, but the panel has to go. You don’t need to rewire the whole house – you need to replace the main service panel with a modern 200-amp unit, which is a one-day job for our crew. On a ranch-style home off Mill Street near historic downtown Lewisville, our crew found a Zinsco panel that had quietly fed the house for 40 years. We replaced it with a 200-amp service panel, then installed a Tesla Powerwall 3 and relocated existing solar circuits with a rapid shutdown compliant design – all in one trip so the homeowner could pass Oncor’s interconnection inspection without a second visit. That’s the normal sequence, and we quote it upfront so there’s no surprise.
The honest answer is your house is older. If you live in the 75057 ZIP in a 70s or 80s home, your quote almost certainly includes a $2,000 to $3,500 panel upgrade your neighbor in a 2010s Frisco build didn’t need. That upfront cost adds roughly two years to the payback math. It’s not a bad deal – it’s a necessary upgrade that also makes your home safer – but it changes the timeline. We’ll show you the year-25 output numbers, not the day-one brochure figure, so you can decide with real arithmetic. Call (877) 550-6892 if you want us to run the numbers on your specific address.
