Solar Battery Cost: Is It Worth It? (2026) | ConsumerAffairs®
This guide breaks down solar battery costs in plain language. You''ll learn what drives the price and whether a battery makes sense for your home.
A report from the National Renewable Energy Laboratory (NREL) estimates that a solar battery including installation can cost almost $19,000* to install, including the price of the battery itself and labor. Installation and permitting fees vary by location and installer, but the NREL estimates the battery itself typically costs $16,007.
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.
While prices for solar batteries in 2025 range widely from around $7,000 to $15,000 installed, the long-term benefits can outweigh the initial expense. A battery allows you to store excess solar energy for nighttime use, reduce your reliance on the grid, and maintain power during outages.
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:
