How much does a solar battery cost?

Installed home battery pricing typically runs around $1,000 per kWh of usable capacity, plus a base charge for the gateway, panel work and labor. A single ~13 kWh unit installed is often in the $12,000-$18,000 range before incentives; adding a battery alongside a new solar system costs less than adding one later.

What's in the price

• Battery hardware (scales with capacity).
• Backup gateway / automatic transfer switch.
• Electrical work — often a subpanel for backed-up circuits.
• Labor and permitting.

Incentives

Standalone or paired storage of 3 kWh+ was eligible for the 30% federal residential credit through 2025; 2026+ residential installs do not qualify. Some states and utilities run their own storage incentives — check incentives by state.
