What Is a Tesla Powerwall?
The Tesla Powerwall is a rechargeable home battery that stores electricity for use during power outages or when energy rates are higher. It can charge from solar panels, the electric grid, or a generator, allowing you to manage energy use more efficiently and reduce dependency on the grid.
Powerwall 2 vs Powerwall 3
The Powerwall 2 has been available since 2016, offering a 13.5 kWh capacity with a 5 kW continuous output. The newer Powerwall 3 retains the same storage capacity but doubles the output to 11.5 kW, making it suitable for homes with higher energy demands.
Tesla Powerwall Pricing in 2025
| Model | Battery Cost | Installation | Total Cost |
|---|---|---|---|
| Powerwall 2 | $9,300 | $2,200 | $11,500 |
| Powerwall 3 | $9,300 | $6,000 | $15,300 |
How Much Is a Tesla Powerwall Installed?
Installation adds a significant cost, especially for the Powerwall 3, which may require electrical panel upgrades. A Powerwall 2 installed averages $11,500, while the Powerwall 3 can reach $15,300. If you install multiple units, additional Powerwalls cost less—around $9,267 each when installed together.
How Much Is a Tesla Powerwall with Solar Panels?
A full Tesla solar + Powerwall system can cost between $25,000 and $40,000 before incentives. Although the upfront cost is higher, combining solar with a Powerwall provides better backup protection and can dramatically reduce your utility bills long-term.
Federal Tax Credit (ITC)
Thanks to the 30% federal solar tax credit, homeowners can deduct nearly a third of their total Powerwall system costs—including installation and solar panels—from their federal taxes. This incentive is available through at least 2032 under the Inflation Reduction Act.
How Much Energy Does a Tesla Powerwall Store?
- Powerwall 2: 13.5 kWh with 5 kW continuous power
- Powerwall 3: 13.5 kWh with 11.5 kW continuous power
This is typically enough to power a home’s essentials for several hours or to shift your usage to off-peak times.
Availability and Ordering
Tesla Powerwalls can be ordered directly through Tesla’s website or from certified solar installers. Demand for the Powerwall 3 remains high, so expect longer lead times for installation in some areas.
