Why Arizona is a rate-plan game
Some states hand out solar and battery rebates. Arizona mostly does not. Here the lever is your utility rate plan and the hours you use power. A mailed rebate check is rarely the point.
That sounds like a downside. It puts you in control. You pick the plan and the schedule, and the savings follow.
APS customers
APS offers time-of-use and EV-friendly rate plans that price power lower overnight. Charge the car and run the battery in those windows and the per-mile cost drops. Confirm the current plan options with APS before you switch.
SRP customers
SRP runs its own EV and time-of-use price plans, plus demand-based options that reward spreading big loads out. An EV charger on a smart schedule fits these plans well. Check the latest SRP plan details directly.
TEP customers
TEP, serving the Tucson area, offers time-of-use and EV rate plans on the same logic. Off-peak charging and battery use carry the savings. Verify current TEP options before enrolling.
Federal incentives in 2026
Federal credits for EV chargers and home batteries changed for 2026. Do not assume last year's credit still applies. Confirm current federal eligibility before you budget around it.
How to actually save
