Although I don't necessarily agree with some of the viewpoints, I do keep an eye on writings and opinions of other people preparing for SHTF. Quite a few are reactionary, racist, and paranoid, but might have some interesting ideas worth thinking further about.
Sometimes, though, you just have to wonder. One writer talked about the possibility of the electrical grid being taken down by a deliberate EMP blast. Not that this isn't a concern. But his point was that grid power was vulnerable to this sort of attack, ergo you should invest in (his book about) solar panels.
"His book about" being the operative term. Actually, his book about making your own panels from individual cells... Never mind that, all in all, it's only worth doing if you can get the individual cells much cheaper than a panel - and you know about the extras that aren't always obvious, that you can connect them in a way that is going to be effective in the long-term.
And - the reason that electronics fail in an EMP blast is that bits of wires act as antennae, and the voltage difference creates a current which can quickly burn out delicate components.
In short - if an EMP pulse hits you, it doesn't matter that you're not connected to the grid, your solar panels could fry, the charge controller will die, and you're in the same boat as everyone else. About the only way to protect things is to have them locked away in a metal cabinet, not in use, without any wires to the outside world - keep them in storage until after everything has happened. If you're relying on power to keep your refrigerator going, you'll have a problem.
It's this sort of information that really annoys me. The situation is one that makes me prefer non-electronic solutions to problems. Evaporation systems, that rely on only the evaporation of water, aren't as efficient or capable as a household fridge, but I'd rather have a few of them sitting away than relying on a complex system that you couldn't repair easily...
