It’s estimated that power outages affect Americans for roughly two hours annually, excluding major events. Luckily, there’s a solution that provides continuous energy during an outage —Tesla’s Powerwall. 

Tesla’s Powerwall stores solar energy through an integrated battery system. This is used for backup protection in the event of a power outage. Your system can detect local outages and recharges automatically, harnessing the sun’s energy so your appliances will run for days at a time. 

You might find yourself wondering about the Tesla Powerwall battery cost. This helpful guide explains what you need to know about installation expenses, incentives, rebates, energy savings, and more. 

Tesla Powerwall Battery Cost

Tesla Powerwall solar battery varies in price with your location determining what you’ll pay. On average, you can expect to pay between $9,000 and $18,000. Where you purchase the Powerwall also affects its price. 

You can purchase directly from Tesla’s website —you’d receive a discount for purchasing multiple Powerwalls at once. If you’re adding to an existing system, you may save even more. For example, three Powerwalls are roughly $25,000 whereas a single Powerwall is roughly $9,000. 

The price you pay won’t include delivery and installation. Once you purchase your Powerwall, you’ll need to locate a technician and pay for the labor to connect it. The average cost for labor is $3,000. 

The most expensive option would be to purchase a Tesla Powerwall from a certified Tesla installer. The average cost is $15,000 but can be as high as $18,000. 

Incentives and Rebates

Throughout the US, Tesla qualifies for battery storage incentives. The Federal Investment Tax Credit (ITC) applies to the total cost of the Solar Roof’s solar portion. It also applies to the cost of the Powerwall itself.

There are other tax credits throughout the U.S. For example, Vermont residents may receive a 30% tax credit. This 30% applies to what they paid for their Powerwall.  

Certain states may offer additional rebates and incentives. In California, residents benefit from an SGIP Incentive. This incentive may cover the bulk of installing your Powerwall.  

Installation Requirements

When you install your Powerwall, you’ll need access to the wall, ground, and surrounding space so workers can access key location points. 

Ensure you have an in-service Internet connection, either wired or wireless, so you can monitor your Powerwall system using your Tesla app. Although wired home networks are preferable, they’re not required. Powerwall can utilize your internet via an internal cellular connection. 

Since your Powerwall will most likely be installed with the complete Solar System, you’ll need to apply for permits before moving forward with any installation. The cost to apply for permits is nominal compared to the energy savings you can expect. 

How to Reduce Energy Bills

The Tesla Powerwall is comprised of smart batteries that are powered by the Tesla Solar System. These batteries may also be powered by a power grid. They’re contained in a package that’s monitored electronically with the Powerwall supplying your home’s electrical needs.

The Powerwall works to provide continuous energy supplies to your entire home. Should you experience a power outage, your Powerwall will supply your home with all the power it needs. 

This is how you can expect to reduce energy bills and save money

Utility Bills

To keep energy bills low, use your Powerwall to collect energy from power grids during times of the day when tariffs are low. You could also do this late at night, storing energy to use during prime hours of the day.

The result is reduced energy consumption. Although you can do this with a Tesla Powerwall alone (foregoing the complete Solar System), it’s best if you have your own means of generating energy to use at your discretion. 

Once you complete your Powerwall battery installation, you’ll remain connected to your electrical provider. You should notice a drop in rates, depending on your energy consumption and usage.

Solar power is an excellent way to decrease your electric bills and can become your primary energy source. The grid may become nothing more than a secondary means of storing energy on cloudy days or during inclement weather. 

Local rates, the time of day you use energy within your home, and your specific energy needs all dictate your utility costs. You can work to further reduce energy bills by utilizing the Time-Based Control that Tesla’s Powerwall provides. Simply select a time that works best with your energy needs. 

Tesla App

Tesla’s app works to further reduce energy bills. You can optimize how much energy you consume, impacting the amount you pay monthly.

Since Tesla’s Powerwall is designed to reduce the amount of power you require from the main grid, you can lower your energy bills. When you use a rate plan and the app in tandem, you’ll receive maximum savings. 

When using the app, you’ll benefit from the Time-Based Control features that control when your Powerwall charges and discharges. The app works to maximize energy generation while lowering energy consumption costs. This is commonly referred to as load shifting.
