How long until solar pays for itself in Arizona?
In Arizona, solar panels pay for themselves in about 6 years. That is faster than the U.S. average payback of roughly 8 years. After the payback point, the electricity your panels produce is essentially free for the remaining 15+ years of their warranty.
The payback period is the net system cost divided by your annual electricity savings. A higher local electricity rate and more sun hours both shorten it.

What affects solar payback in Arizona?
- Electricity rate: Arizona's rate of $0.13/kWh sets how much each solar kWh saves you — higher rates mean faster payback.
- Sun hours: Arizona averages 6.5 peak sun hours per day, which determines how much energy your system produces.
- Net metering: Arizona offers net metering, so surplus solar earns bill credits and shortens payback.
- Incentives: The 30% federal tax credit reduces your net cost and speeds the return.
- Installation cost: At $2.65/watt, lower install prices in Arizona pay back sooner.
