Arizona is pretty naturally dry.
However the garbage can lid etc. would not work for a solar array. Is there no way to protect an array out in the sun and operating from EMP?

The blocking diode is generally robust, but I would put a UL1449 rated surge protection device (with associated ground) as close to the array as possible. the inverter/charge controller should be in an EMP-hardened container (you’ll need to access it more often - so don’t put it in a garbage can.
All electrical inputs and outputs should have an RF filter installed, including the DC input from the solar array - and the leads from the battery bank. It’s more complicated when you have an interactive grid-tied system.
