What this means in Arizona
This appliance runs on much the same schedule regardless of climate, so the figure above is a reasonable year-round estimate for Arizona. What changes it is your own usage pattern rather than the weather.
Why Arizona pays what it does
Arizona is a regulated market, so your utility is the only supplier and the rate is set through the state commission rather than by competition. Pricing tends to be steadier than in deregulated states, and there is no switching decision available. The levers are all on your side of the meter.
At 15.23 cents, Arizona ranks 20 of 51 from cheapest to most expensive. The West regional average is 19.65 cents. Roughly half of any residential bill is transmission and distribution rather than generation, which is why rates keep climbing even when fuel prices fall.

Lowering the number in Arizona
- Use the moisture sensor cycle, not timed dry. Timed drying keeps heating after the clothes are dry.
- Clean the lint filter every load and the vent duct yearly. Restricted airflow lengthens every cycle and causes fires.
- Spin twice for towels and jeans. Water removed in the washer is water the dryer does not evaporate.
- Run consecutive loads. A drum already hot does not need reheating.
- Line dry what you easily can. Sheets and towels dry outdoors for nothing.
Offsetting it with solar in Arizona
This load uses about 3.00 kWh a day. Covering that would take roughly 3 standard 400 W panels at typical sun hours, an array of about 1.20 kW. Because it offsets electricity worth 15.23 cents rather than the national 18.44 cents, the same array is worth less here than the national payback figures suggest.
A dryer is a short, enormous load. Running one on solar means either a very large array or accepting that it only runs on bright afternoons. Full sizing, including battery and inverter requirements, is on the solar sizing page for this appliance.
