Tesla Powerwall 3 Installation in Dallas-Fort Worth

North Texas Solar is a Tesla Certified Installer serving homeowners across Dallas-Fort Worth. We design, install, and commission Tesla Powerwall 3 systems paired with solar — built for the realities of the Texas grid, the Texas climate, and the way Texans actually use power. Whether you’re adding battery backup to an existing solar array or starting from scratch with a whole-home solar-plus-storage system, we’ll put together a Powerwall 3 system sized for your home and your usage.

We’re locally owned, based in Fort Worth, and we’ve been installing residential solar and battery systems across DFW since 2015. Our crews handle the full installation in-house, and every job comes with our 25-year workmanship warranty.

Why DFW Homeowners Choose the Tesla Powerwall 3

Texas has its own reasons for wanting backup power, and the Powerwall 3 is built for them.

Grid reliability. Winter Storm Uri in February 2021 left millions of Texans without power for days. ERCOT issues haven’t gone away. Summer heat waves push the grid into emergency operations multiple times a year. A Powerwall 3 keeps your home running through outages without a generator, fuel, or noise.

Time-of-use rate protection. As more Texas utilities shift toward time-of-use pricing, a Powerwall 3 lets you store solar production during the day and pull from your battery during peak-rate hours instead of buying expensive grid power.

Heat performance. The Powerwall 3 is rated for outdoor installation in Texas summers, with thermal management designed to keep the battery operating efficiently in extreme heat. That matters when your unit is sitting against the side of a Dallas garage in August.

True energy independence. Paired with solar, a Powerwall 3 system can take your home largely off-grid during normal operation — you generate, store, and use your own power, with the grid as backup rather than primary supply.

 

Tesla app integration. You can see exactly what your home is doing in real time: solar production, battery state of charge, grid draw, and home usage. You can set backup reserve, switch modes, and get outage notifications, all from your phone.

Tesla Powerwall 3 Specifications

The Powerwall 3 is Tesla’s third-generation home battery, redesigned for higher continuous output and integrated solar inverter capability.

• Usable capacity: 13.5 kWh
• Continuous power output: 11.5 kW
• Integrated solar inverter: Yes — up to 20 kW of solar input across six MPPTs
• Operating temperature: -4°F to 122°F
• Installation: Floor or wall mounted, indoor or outdoor
• Warranty: 10 years
• Certifications: UL, IEEE, and Tesla’s own certification requirements
• Backup transition: Seamless — your home stays powered through grid outages without interruption

Most DFW homes we work with need between one and three Powerwall 3 units to support whole-home operation through extended outages. The exact number depends on your actual electric usage, your solar production, what loads you want to back up, and how long you want to run during an outage. We’ll review your utility bills and usage patterns before we recommend a configuration.

 

We’re a Tesla Certified Installer in DFW

Tesla’s Certified Installer program isn’t given to every solar company. It requires manufacturer-specific training, demonstrated installation quality on prior projects, ongoing performance review, and compliance with Tesla’s design and commissioning standards.

What that means for you:

• Proper system design. A Powerwall 3 sized and configured incorrectly will underperform or fail to meet your backup expectations. Tesla certification means we’ve been trained on how to design these systems correctly.
• Manufacturer warranty preservation. Tesla’s 10-year warranty stays intact when the system is installed by a certified installer to spec.
• Tesla app support. We commission your system to communicate properly with the Tesla app, so the monitoring features work out of the box.
• Direct manufacturer relationship. If anything ever comes up with your equipment, we have a direct line to Tesla support — you’re not stuck in a phone tree.

We’re also a Good Contractors List member and BBB accredited, with our $25,000 workmanship guarantee through the Good Contractors List program.

The Oncor Take A Load Off Texas Incentive

If you live in Oncor’s service area — which covers most of Dallas-Fort Worth — you may qualify for a battery storage incentive through the Take A Load Off Texas program. This incentive is designed to encourage residential battery storage that helps support grid stability during high-demand periods.

A few key points homeowners should understand:

• Solar is required. The incentive applies to battery systems paired with solar, not standalone battery installs.
• The incentive amount is calculated, not fixed. It depends on your solar system’s production capacity, panel orientation, expected output, and battery configuration. There isn’t a flat “X dollars per Powerwall” figure.
• It can be substantial. For a typical Powerwall 3 install paired with a properly sized solar array, the incentive is often one of the larger incentives available to Texas homeowners.
• Eligibility and program details change every year. Oncor updates the program structure and budget, so the incentive available today may differ from what was offered a year ago.
• This incentive has a fixed annual budget is first come first served. 

We handle the application as part of our standard process. During your consultation, we’ll estimate the expected incentive for your specific design and walk you through how it factors into your total project cost.

Our Tesla Powerwall 3 Installation Process

Here’s what to expect from your first call through the day your system goes live:

1. Initial consultation (~10 minutes). A phone call to understand your goals — backup power, lower bills, energy independence, or all three. We’ll ask about your utility, your roof, and roughly what you’re paying for electricity.

2. Custom system design. We pull your utility usage history, evaluate your roof for solar (if you don’t already have it), and model out what Powerwall 3 configuration meets your goals. You’ll get a detailed proposal showing system sizing, expected production, expected rebates, financing options, and final cost.

3. Site survey. Our team comes out to verify roof condition, electrical panel capacity, Powerwall placement options, and any structural or code considerations specific to your home.

4. Permitting, HOA, and utility coordination. We handle the city permitting, HOA approval if needed, and the Oncor interconnection application. This is the slowest part of any solar-plus-storage project, but you don’t have to manage it — we do.

5. Installation. Most Powerwall 3 installs take one to three days depending on whether we’re also installing solar. Our full-time, in-house crews handle the work — we don’t subcontract our primary installation labor.

6. Commissioning and Tesla app setup. We test every part of the system before we leave, set up your Tesla app account, walk you through what each mode does, and make sure your backup behavior is configured the way you want it.

7. Permission to Operate and ongoing support. After Oncor issues PTO, your system is officially live. We stay your point of contact for the life of the system — warranty service, app questions, expansion planning if you want to add capacity later.

Frequently Asked Questions

How much does a Tesla Powerwall 3 cost in Texas? 

Cost varies based on how many units you need, whether you’re adding to existing solar or installing a complete solar-plus-storage system, your home’s electrical configuration, and which rebates and tax incentives apply. We give every homeowner a free quote with customized, site-specific pricing so you can see exactly what’s included and what’s optional to accomplish your specific goals.

Will a Tesla Powerwall 3 power my whole house? 

The short answer is yes, but it depends on your home size, your typical electrical load, and how long you want to run during an outage. A typical DFW home may need one to three Powerwall 3 units for whole-home backup, including AC, refrigeration, and full appliance use. We size the system based on your actual usage data, not estimates.

How long does Tesla Powerwall 3 installation take? 

A Powerwall-only install (adding storage to existing solar) is usually one to two days of on-site work. A complete solar-plus-storage install runs two to three days. The full project from signed contract to system live — including permitting, HOA approval if needed, and Oncor interconnection — typically takes four to eight weeks, but varies significantly depending on the specific city requirements and processes.

Do I need solar panels to install a Tesla Powerwall 3? 

No, solar panels are not required to install a Powerwall 3. The Powerwall 3 can operate without solar, but two things to know: first, the Oncor Take A Load Off Texas rebate requires a solar component. Second, without solar you lose the cost-savings benefit of storing your own production. We recommend pairing Powerwall 3 with solar in nearly every case, but there are cases where a stand-alone battery installation can save you money if you have a compatible electric plan.

Is the Powerwall 3 better than the Powerwall 2? 

Tesla has phased out the Powerwall 2. The Powerwall 3 is the current model and offers higher continuous power output, an integrated solar inverter, and a more streamlined installation footprint than its predecessor. If you have an existing Powerwall 2, it still works — Tesla continues to support it — but new installs are Powerwall 3. If you need service on an existing Powerwall 2 system we can help, but we do not install new Powerwall 2 systems.

What’s the warranty on a Tesla Powerwall 3? 

Tesla provides a 10-year manufacturer warranty on the Powerwall 3 itself. North Texas Solar adds a 25-year workmanship warranty covering our installation. Through our Good Contractors List membership, your project is also covered by a third-party $25,000 workmanship guarantee.

Can I add a Tesla Powerwall 3 to my existing solar system? 

Yes, in most cases. We’ll review your current solar setup, inverter compatibility, electrical panel capacity, and roof conditions to determine the best integration approach. Sometimes existing string inverters need to be reconfigured; other times the Powerwall 3 can slot in cleanly with minimal changes.

How do I qualify for the Oncor battery Incentive? 

You need to be in Oncor’s service territory, install a battery paired with solar, and have the system designed and commissioned to program specifications. We handle the rebate application during the installation process and calculate the expected incentive amount during your consultation so you know what to expect before you sign anything. This incentive is for new installations only. Add-ons do not qualify.

Tesla Powerwall versus Enphase IQ Battery — which should I choose? 

Both are quality products and we install both. The right choice depends on your existing system, your power output needs, your roof setup, and your monitoring preferences. During your consultation we’ll walk through the tradeoffs based on your specific situation rather than recommending one over the other generically.
