The Tesla Powerwall is a lithium-ion energy storage solution designed to charge using solar power or energy from the grid. When paired with solar panels, the system directs solar energy to power your home's appliances. Any excess solar energy not immediately used is stored in the Powerwall battery for later use.
The Tesla Powerwall 3 costs about $15,400 before incentives and taxes are considered. At $1,140 per kWh of storage, the Powerwall is one of the most affordable home battery solutions available. The combination of its cost and popularity earned it the first place spot in our list of the Best Solar Batteries of 2025.
Limited stacking: You can install up to four Tesla Powerwall 3s together for a total capacity of 54 kWh. A Powerwall 2 system can have up to 10 batteries for a whopping 135 kWh of capacity. Most homeowners don't need a system of that size.
The Tesla Powerwall is backed by a 10-year warranty that guarantees that the battery will retain at least 70% of its capacity by the end of the warranty period. The unlimited cycle warranty is valid only if the battery is used for solar self-consumption, time-based control, and backup reserve.
