Well, I hope you are wrong :) I imagine that most transformers etc are somewhat over-engineered. I mean, they get destroyed by things like lightening strikes, but are we talking about the same energy levels? I really have no idea.

You make a good point about rooftop solar+battery. Perhaps an event like this would make us more open to decentralised energy production.

Regarding how vulnerable solar panels are - in my limited understanding the problem comes from things that will induct electrical currents from EM, so basically anything with long wires (transmission lines and transformers etc.) So I would guess that semiconductors like solar panels would not be damaged directly. I'd also like to hear from any experts though.
