How Much Do Solar Batteries Cost?
Adding an energy storage battery to a residential solar panel system typically costs $7,000 to $18,000. Some smaller batteries cost just a few hundred dollars, while premium
If you're looking to buy battery storage for your solar panels, you can probably expect to pay between $7,000 and $18,000. Just know that the overall price range for a solar battery is even wider, with prices anywhere from a few hundred dollars to $30,000+, depending on what you buy, who you buy it from and how you plan to use it.
In 2025, a typical solar battery installation costs $9,000–$18,000 before incentives and $6,000–$12,000 after credits. By 2026, continued cost declines are expected to make home energy storage even more accessible, with prices averaging 8–12% lower than current levels.
Experts expect solar battery prices to continue declining through 2026. Based on data from BloombergNEF and Wood Mackenzie, lithium battery pack costs are projected to drop 8–12% year over year, reaching approximately $550–$850 per usable kWh installed by late 2026. Factors influencing 2026 pricing trends include:
Most solar batteries last between 10 and 15 years, depending on the type of battery, how often it's used and how well it's maintained. Lithium-ion batteries, the most common type for home solar systems, typically have longer lifespans and higher efficiency compared to lead-acid options.
