What the planet gets
Net metering credits exported power against what you draw from the grid. Rates vary by state, California's NEM 3.0 pays much less for exports than 1:1 states.

How Arizona compares to the US average
Three numbers decide most of your payback. Here's where Arizona sits against the national picture.
Electricity rate
15¢/kWh
US average: 17¢/kWh
Cheaper power means each solar kWh saves less
Solar generation
~5 kWh/kW/day
US average: ~4.5 kWh/kW/day
More sun per panel than the US average
Typical payback
15.2 years
US average: 10.6 years
Slower than the US average on a $150 bill
Solar cost & savings by system size in Arizona
Computed with Arizona's rate (15¢/kWh), sun (~5 kWh/kW/day), and its reduced export credit, at the 2026 national benchmark of ~$2.75/W with no federal credit.
| System size | Installed cost | Generation/mo | Annual savings | Payback |
|---|---|---|---|---|
| 4kW | ~$11,000 | ~600 kWh | ~$724 | ~15.2 yrs |
| 6kW | ~$16,500 | ~900 kWh | ~$1,085 | ~15.2 yrs |
| 8kW | ~$22,000 | ~1,200 kWh | ~$1,447 | ~15.2 yrs |
| 10kW | ~$27,500 | ~1,500 kWh | ~$1,809 | ~15.2 yrs |
Savings assume a home large enough to use this output. Figures last reviewed July 2026,size a system from your actual bill instead.
How exports are paid in Arizona
Arizona ended retail net metering in 2017; exports earn a utility 'export rate' (~7-10¢) that ratchets down over time.
Because Arizona pays less than the full retail rate for exported power, the numbers reward using more of your own solar, running big loads in daylight, or adding a battery to store the surplus instead of exporting it cheaply.
Policies change often, always confirm current rules with your utility or at DSIREbefore deciding.

Arizona solar FAQs
Is solar worth it in Arizona in 2026?
For a typical $150/month bill, we estimate a Arizona system pays for itself in about 15.2 years, with no federal tax credit assumed (the residential credit expired at the end of 2025). At 15¢/kWh with net billing (reduced export rate), the case is workable but depends on your roof, usage pattern, and quotes.
How much does a solar system cost in Arizona?
At 2026 benchmark prices (~$2.75/W), a 6kW system runs about $16,500 installed, generating roughly 900 kWh a month in Arizona's sun. Local quotes vary 20-40% between installers, so always collect several.
What is the net metering policy in Arizona?
Arizona ended retail net metering in 2017; exports earn a utility 'export rate' (~7-10¢) that ratchets down over time.
Does Arizona have a state solar incentive?
$1,000 state tax credit; exceptional sun makes self-consumption very productive. Since the federal residential credit ended in 2025, state and utility incentives are the main upfront help available.
How many solar panels do I need in Arizona?
A 6.5 kW system suits a typical $150/month bill in Arizona, that's roughly 16 modern 425W panels needing about 423 sq ft of unshaded roof. Enter your own bill in the calculator above for a precise size.
