Solar panels in Arizona: savings by city
Arizona’s average residential electricity price for January to August 2026 was 15.36¢ per kWh, 2.83¢ below the US average of 18.19¢ (EIA).
Panels in the 15 cities we cover here produce an average of 1,802 kWh per kW a year, 19% more than the average of the 400 US cities in our data (1,517 kWh).
At this price, a system that covers an average US home’s use (10,788 kWh a year) saves about $1,657 in its first year anywhere in Arizona. Sunnier cities need a smaller system to do it, so it costs less at any price per watt.
