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.
Solar battery installation costs vary dramatically based on system complexity, local labor rates, and equipment choices. Understanding these factors helps you budget accurately and identify fair pricing. Labor costs typically range from $1,500-4,000 depending on installation complexity.
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.
The average cost to install a solar battery in 2025 ranges from $9,000 to $19,000, with most homeowners spending about $13,000. The total price depends mainly on the type and capacity of the battery, as well as the complexity of your system.
Two cabinets can connect to a single inverter for up to 36 kWh total backup power. Whole-house solar battery backup costs $20,000 to $32,000 installed, not including solar panels. The average home uses 28 to 30 kWh per day, requiring batteries with at least that total capacity or more to power the entire home for one day.
