How much does the Tesla Powerwall cost?

The cost of a Tesla Powerwall varies depending on a few factors, including where you live, how many you plan to install, and what model you choose. The current price of a single Tesla Powerwall 2 is $8,700 before the cost of installation and delivery, and before savings of up to 30 percent from the federal tax credit.

The cost of installation can vary depending on the complexity of the installation, but it typically costs between $1,000 and $5,000. The total cost of a Tesla Powerwall system can range from $10,000 to $20,000.

The federal solar tax credit is a 30% tax credit on the cost of solar energy systems, including batteries. This means that you can deduct 30% of the cost of your Tesla Powerwall from your federal income taxes. The tax credit is available for both homeowners and businesses.

In addition to the federal tax credit, there may be state or local incentives available for Tesla Powerwall installations. These incentives can vary, so it is important to check with your local utility company or solar installer.

Here are some of the factors that can affect the cost of a Tesla Powerwall system:

  • The size of your home and your energy usage
  • The number of Powerwalls you need
  • The complexity of the installation
  • The cost of labor in your area
  • State and local incentives

If you are considering installing a Tesla Powerwall, it is important to factor in all of these costs to get an accurate estimate of the total cost.

Here are some of the benefits of installing a Tesla Powerwall:

  • Reduce your reliance on the grid and save money on your electricity bills.
  • Power your home during an outage.
  • Extend the life of your solar panels.
  • Increase the value of your home.

If you are looking for a way to save money on your energy bills and make your home more sustainable, a Tesla Powerwall is a good option to consider.

How Does the Powerwall Work?

How Does the Powerwall Work?

The Tesla Powerwall has three operating modes to help homeowners customize the battery to their needs. It offers automatic backup power during blackouts and periods of high electricity rates. The Powerwall also requires several components, including a wifi-enabled gateway, to function. Below is an overview of the Powerwall’s operating modes and basic components.

Modes of Operation

The Powerwall includes three operating modes to manage and improve battery performance.

  • Self-powered mode: The Powerwall will collect excess energy generated during the day and store it for use at night. The battery continues to charge until the capacity is reached. Any excess energy beyond this threshold is sent back to the power grid. This mode offers the best cost savings by effectively using your excess solar power.
  • Backup reserve mode: This mode provides electricity to your home during power outages. The Powerwall automatically switches to this function when it detects no active power generation from your system. You can adjust the reserved percentage to allocate more or less stored power for future outages.
  • Time-based control: This option pairs well with utility companies that use time-of-use (TOU) pricing for electricity. Your TOU rate fluctuates based on the time of day and power demand. The Powerwall will charge during low TOU rate time periods and discharge energy when rates are high, providing automatic savings throughout the year.

Parts of the Powerwall

Here’s an overview of a Powerwall’s basic parts.

  • Powerwall battery: This rechargeable battery stores your system’s excess energy.
  • Tesla Gateway (Backup Gateway 2): This device regulates your solar system’s grid connection and monitors for outages, tracks energy use, and controls backup power functions. The Backup Gateway 2 is the latest version used by both Powerwall models and requires a Wi-Fi or ethernet connection.
  • Gateway meters: The Powerwall contains two internal meters to regulate power charging and distribution to and from your solar and grid systems.
  • Backup switch: This component works with the backup power features and detects power outages. It works with whole-home backup configurations and requires approval from your utility company.
  • Tesla solar shutdown device: This safety device installs on your roof and provides immediate inverter shutdowns as a safety precaution. The National Electric Code, issued by the National Fire Protection Association, requires this device.

Life Span and Warranty

Both Powerwall models come with an industry-standard 10-year warranty. Your Powerwall may last longer than 10 years, but its performance will reduce over time. Most solar panels last up to 25 years or longer, so you may need to replace your Powerwall to match your system’s life span.

The Powerwall warranty includes the following clauses:

  • Unlimited charge cycles: A charge cycle is the process of fully charging and draining your battery. This clause includes unlimited charge cycles for the full 10-year coverage length.
  • Four-year workmanship warranty: This warranty covers any replacements or repairs due to poor installation. It also covers the shipping for any necessary replacement parts.
  • 70% end-of-life capacity clause: The Powerwall has an end-of-cycle capacity of 70%, meaning it will provide at least 70% of its original 13.5 kWh capacity. This is higher than the average end-of-warranty capacity of around 60%.How Many Powerwalls Do I Need?

How Many Powerwalls Do I Need?

How long a Powerwall can supply your home with energy is weather-dependent.

With one Powerwall:

  • Cloudy/winter days: 1 day
  • Sunny/summer days: 2.5 days

With two Powerwalls:

  • Cloudy/winter days: 1.5 days
  • Sunny/summer days: 7+ days

The battery can provide electricity to most 120-volt appliances and electric outlets. High-powered systems, such as air-conditioners, require additional Powerwalls.

The Powerwall can function as a whole-home or partial backup system based on your needs. Below is an overview of each configuration:

  • Whole-house backup: This configuration provides whole-home power during an outage. If you have several high-power appliances, your battery life will reduce more quickly. This setup is best for homeowners living in areas with inclement weather that causes blackouts. This is also a good option for those who want backup power for their home and can afford multiple Powerwalls. Most homes will need three or more Powerwalls for adequate power backup.
  • Partial-home backup: With a partial backup option, your Powerwall only supplies power to essential appliances, such as your HVAC system and refrigerator, during an outage. Consider this configuration if you’re keeping your investment to a minimum and only focusing on essential appliances. This setup requires one or two Powerwalls.

How Much Space Does the Powerwall Need?

You’ll need adequate space for the full Powerwall system, including the battery and gateway box. The Powerwall needs a 4-by-5-foot space with 6 feet of clearance in the front. The gateway box requires a 2-by-3-foot space and a strong Wi-Fi signal or ethernet cable connection.
