Probably not quite enough good area due to mountains ect. in the entire state of Arizona.

Less than perfect locations in the snowy/ rainy North will average about half of that on an annual basis and near zero for many days at a time in the Winter. But if we could make the panels and racking last for 100 years at a time, and make the expendable electronic components in the inverter easy to swap out. And convert all heat, agriculture, mining, industry, transportation, to electric, it will be much better than nothing. And much easier to maintain by hand than 100 meter tall wind turbines which start to wear out every 15 years.

The lowest carbon electric regions all have mostly hydro or nuclear.
