The electronics is much more sensitive to high voltage/static, so they are burnt out by the EMP. They can be protected by an electrostatic shield (Faraday cage), but you need to make sure it is totally disconnected, and that no wire that can pick up the EMP will connect it to the components. eg. if you store your PC in a metal container, it would be protected during the EMP.

For solar cells, if exposed, will the generated voltage damage the cells is the question. To be safe, they should be protected also, otherwise, the second best is to disconnect the wires going to the panels temprarily; wrapping the panels in aluminum would also shield the panels from EMP.
