Tesla Powerwall

What Is The Tesla Powerwall?

The Tesla Powerwall is a rechargeable lithium-ion battery that is primarily intended for home storage and is often paired with residential solar panels. It is designed for EV charging, self-consumption, shifting power usage, and short-term backup power. Each Tesla Powerwall 2 offers 13.5kWh of usable energy storage capacity and can be stacked in a chain.

How does the Tesla Powerwall work?

The Powerwall solar battery intelligently stores energy during times when energy rates are lower and uses the stored energy when electricity prices are higher. The self-contained, waterproof unit is always on, operates quietly, and can be mounted on the floor or wall individually or as part of a stack of multiple batteries.

The Tesla Powerwall is usually paired with a home solar panel system. A house equipped with solar panels usually produces more electricity during the day than it consumes at the time of generation. This extra solar power can be stored in the Powerwall battery instead of being sent back to the electric grid. At night or when the solar panels are not producing enough electricity to meet the home’s demand, the homeowner can pull energy from the Tesla Powerwall instead of having to buy it from the utility.


What are the benefits of the Tesla battery?

The benefits of the Tesla Powerwall are that it is a high quality and attractive home battery with smart software and a user-friendly smartphone app at a relatively affordable price. The Tesla solar battery is one of the most popular options for home backup power and EV charging.

The Tesla Powerwall can automatically detect a power outage, disconnect from the grid, and then restore power to your home in less than a second, quickly enough that you may not even be aware that there was an outage. A single Powerwall has enough energy storage capacity to power an average home for an evening during a power outage.

If you have solar panels and a Tesla battery, your solar energy system will continue to power your home and recharge the battery during an outage. Without the solar battery, your solar energy system will not be functional until power is restored to the electric grid.

How much does the Tesla Powerwall cost?

On average, the Tesla solar battery costs around $16,000 installed after factoring in equipment (Powerwall, Gateway, and related hardware) and labor costs, and there may be additional installation and financing costs depending on your situation. The battery is only available installed by a certified dealer. The entire system including installation is eligible for the 26% federal tax credit and may also be eligible for local rebates.

What is the Powerwall warranty?

Tesla offers the Powerwall 2 with a 10-year warranty on parts and performance (70% energy retention) after the initial installation. Click here to learn more about the Tesla Powerwall warranty.
