Basics on Tesla Powerwall Battery Storage

While the generation of solar power is the most well-known part of solar panel operation, it's far from the only one that's important during this process. The proper storage of the power that's generated here is also vital for long-term efficiency, and one of the single most useful battery backup products on the market today for this purpose is the Tesla Powerwall.

At Intermountain Wind & Solar, we're happy to offer a wide range of battery backup solutions for our solar power clients, including the Tesla Powerwall. What exactly is the Tesla Powerwall, and what makes it one of the most efficient and desirable battery backup systems available today? Here are some simple facts.

Basics on the Tesla Powerwall

The Tesla Powerwall, known as one of the most advanced battery backup products on the market, is a rechargeable lithium-ion home battery system manufactured by Tesla, Inc. It stores energy that can be used later in either an emergency situation or when your solar panel system isn't generating enough power at certain times of the day.

The Powerwall is made at Tesla's massive battery factory, known as the "Gigafactory," in Reno, Nevada. Tesla uses slightly different chemistry than other battery companies, optimizing the functionality of the backup and protecting it against load shifting and other risks.


One of several great functions of the Powerwall is the modern software that's also part of the setup. This software allows clients to actively view things like solar production, energy consumption, and overall system efficiency in real time. This makes it very easy to manage the battery backup system remotely and keep track of what's happening with your solar power setup.

For instance, if you need to tweak the power output of your system, you can adjust the settings in the software to customize the energy usage for different times of day. This makes it easy to maximize your solar panel system's efficiency and get the most out of your Powerwall.

Qualification for Federal Tax Credit

Naturally, many prospective clients are interested in whether the Tesla Powerwall qualifies for the major federal tax credit that was introduced as part of the Inflation Reduction Act. Good news there: It does! The Powerwall is eligible for a 30% tax credit that can help you save a significant amount of money on installation and other expenses related to your battery backup system.

There also may be state or local incentives available for the Tesla Powerwall, so be sure to check with your local energy provider and ask about what kinds of credits or incentives may be available.

Stackable Output

Another major benefit of the Tesla Powerwall is the fact that it allows stackable output - meaning if you use multiple batteries, power can "stack" between them and the production of energy will increase. This makes it easier for those looking to have a larger system with more powerful output, as it allows multiple Powerwalls to be connected together for maximum efficiency.

This is in comparison to many other batteries, which are not stackable in nature. This means that even if you install multiple of those other battery types, you'll still be capped at a single total power number. With the Powerwall, however, you can keep stacking and increasing the output as long as you need to.

Thermal Management System

Just like Tesla vehicles, the Powerwall contains a liquid heating and cooling system designed to circulate within the battery unit itself. This ensures that, regardless of how hot or cold it is outside, the Powerwall remains at a constant temperature and doesn't overheat - which is essential for efficient operation over time.

There are several benefits of this thermal management system:

  • Reducing degradation: By keeping the temperature of the Powerwall in check, it can help reduce long-term degradation and ensure that your battery backup system remains as powerful as possible for a longer period of time.
  • Reducing energy consumption: Since the battery isn't expending energy to cool itself, this also helps reduce overall energy consumption - another major plus.
  • More resilient for outdoor installs: If you're installing your Powerwall in an outdoor setting, this thermal system also helps make it more resilient against temperature changes and other elements.

All in all, the Tesla Powerwall is a great battery backup option for those looking to get the most out of their solar panel system. With its stackable output capability, modern software features, and thermal management system, it's the perfect choice for anyone looking to get the most out of their solar setup.

It also qualifies for a major federal tax credit, so be sure to ask about what incentives may be available in your area. With all this taken into consideration, the Tesla Powerwall is quickly becoming one of the top battery backup options available for solar power clients.
