How to use
Arizona's major utilities (APS, SRP, TEP) have moved to reduced export compensation and demand charges; SRP in particular uses a different rate structure than APS. This page pre-fills a 6 kW system with Arizona's 6.5 peak-sun hours, $0.15/kWh rate and a net metering credit of 0.95. Adjust the system size, installed cost and federal ITC, then press Calculate.
The simple payback divides your net cost (after the 30% federal ITC) by your first-year savings. Because electricity prices usually rise, the 25-year total understates your real savings if you leave the 3% default in place.
FAQ
What is the solar payback period in Arizona?
It depends on system size, your 0.15/kWh rate and local incentives, but Arizona's 6.5 peak-sun hours make a 6 kW system produce roughly 12,100 kWh a year. Enter your details above for the exact break-even year.
