How Much Do Solar Batteries Cost in 2025?
The average cost to install a solar battery in 2025 ranges from $9,000 to $19,000, with most homeowners spending about $13,000.
Most solar battery storage systems cost $10,000 on average, with most ranging between $6,000 and $12,000. Prices range from $400 for small units to over $20,000 for larger systems. Key cost factors include battery type, capacity, installation labor, and additional equipment.
Solar battery prices are $6,000 to $13,000+ for the unit alone, depending on the capacity, type, and brand. A home solar battery storage system connects to solar panels to store energy and provide backup power in an outage. *Based on a 30% federal tax credit if installed by December 31, 2032.

Solar battery storage capacity typically ranges from 3 kWh to 20 kWh, depending on the model and manufacturer. The higher the storage capacity, the more electricity the battery can hold for use during outages or after sunset. However, more storage comes with a higher price tag.
The downside is interest payments on the loan accrue over time to increase the overall cost of the system. For example, using the example from earlier, financing a 7.9 kW solar system and 12.5 kWh battery with a 20-year loan (with zero money down) would cost nearly $47,000 while paying cash would cost around $30,000.
