A typical home battery storage system costs $9,000 to $18,000 installed before incentives. In Texas, the average is about $17,472 for a 13 kWh system. Battery pack prices have dropped 93% over the past decade, with further declines projected through 2026. The federal 30% tax credit is no longer available for homeowner-purchased systems in 2026, but Texas incentives like the Oncor rebate (up to $9,000) can significantly reduce costs.
