Faraday Cage

[Proud Prepper]

I have a couple more basic questions on the need for a faraday cage:
1. Will devices such as my shortwave radio (solid state) that is NOT plugged in still need to be in a faraday cage? Will an EMP actually cause damage to something not running at the time?
2. Will solar panels require some sort of protection against an EMP themselves? Seems if they do that is quite a concern and planning on keeping electricity should the worst happen is useless.

1. No, if it's disconnected from antenna and power.

2. No, as long as the panels are not connected to anything.
