Is a home battery worth it in Arizona?
In 2026 Arizona battery value comes mainly from time-of-use arbitrage under net billing (no more retail net metering), plus optional utility VPP payments. There is no big state rebate, so the case rests on your TOU plan and export rate. Confirm both with your utility.
Arizona at a glance
- Average residential rate
- 15 cents per kWh
- Net metering
- No retail-rate net metering. Arizona uses net billing / export rates; APS and TEP compensate exports at avoided-cost-style rates, and SRP retired its net-metering plans (moved to net billing, per public reporting). Confirm your utility's current export rate.
- State battery incentive
- No statewide battery rebate. APS offers a residential battery/storage program compensating roughly $110 per average kW per season (per third-party reporting); confirm with APS directly. A state solar tax credit and sales-tax exemption exist but are not battery-specific.

What drives battery value here
Extreme summer heat drives peak demand; outages are less frequent than storm-prone states but heat events and monsoon storms occur. Backup matters most during summer heat and monsoon-season outages. The stronger economic driver is TOU arbitrage: shifting solar into expensive on-peak evening hours under net billing.
The federal picture in 2026
The federal residential purchase credit (Section 25D) expired on December 31, 2025, so a 2026 cash buyer gets nothing federal. The only surviving federal pathway is Section 48E, which a company claims on a lease or PPA. State and utility programs, where they exist, now do the heavy lifting.
