What the adoption figure means
One of the most established rooftop markets in the country: a deep installer bench, and permitting offices that process these applications routinely.
Residential electricity in Arizona averaged 14.91¢ per kilowatt-hour in 2024, 26th of 51 and below the national average of 16.48¢. Prices are close to the national middle, so the export rate your particular utility offers usually decides the outcome rather than the retail rate. Prices and adoption across all 51.
System size and consumption
The average Arizona system was 7.18 kW in 2024, ranking 32nd of 51. Households consumed an average of 12,899 kilowatt-hours a year (8th of 51) — the figure a system here is sized against.
Size your own system from your own kilowatt-hours, not from this average — how to do that.
Who owns the systems
34.1% of Arizona systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 10th of 51.
Third-party ownership is the dominant model, so expect a lease or PPA to be the first thing you are offered. Who claims the federal credit · ownership across all 51.
Battery attachment
3.26% of Arizona solar systems were paired with a battery in 2024, 13th of 51 — 10,345 paired systems.
Attachment is well above average, so storage is a normal part of a quote here rather than an upsell. Attachment across all 51 · does a battery belong in your project.
Where the market is going
Arizona added 21,892 systems in 2024 and has grown at 15.0% a year over five years, 41st of 51. Where growth has turned.
Solar companies and licensing in Arizona
We checked 65 Arizona solar companies against the state licence register. 0.0% did not hold a current licence at the time of checking .
The licence classes that apply to solar work here are CR-11, R-11, CR-5. A company quoting you should hold one of these, and you can confirm it with the issuing authority yourself.
How to verify a licence before you sign.
Method
Figures are computed by HyreSolar from the Form EIA-861 2024 annual files — net-metered residential systems only, penetration counted against residential accounts, sizes as means. EIA publishes the inputs, not these ratios. Full methodology and the underlying CSV.
None of these figures is an estimate for your property. What to work through before you talk to anyone.
Common questions
How many homes in Arizona have solar?
317,033 residential net-metered systems were recorded in Arizona in 2024, against 3,134,733 residential electricity accounts — 10.11% of households, 4th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Arizona?
The average net-metered residential system in Arizona was 7.18 kW in 2024, against a national average of 6.74 kW. Your own system should be sized from twelve months of your kilowatt-hours and your usable roof, not from a state average.
Do people in Arizona add batteries to solar?
3.26% of Arizona systems were paired with storage in 2024, 13th of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Arizona a good state for solar?
On the measures we can compute: residential electricity averages 14.91¢/kWh (26th of 51), households use 12,899 kWh a year (8th of 51), and 10.11% have installed a system (4th of 51). Retail price and export rules move the answer far more than sunshine does, and both are set by your specific utility rather than by the state.
