Re EMP/Solar panels:
Interesting discussion. I’ve wondered about this myself.
That said, I think this whole EMP thing is way over rated. The idea that one high altitude burst would fry every electronic device and all electrical power in the US is just Bunk.
I have been flamed here by “experts” over this. But I still say Bunk.
Close family was in the weapons business at a high level for 40 years. I “trust” that assessment, which was given to me.
