Personaly when it comes to emp. I am more worried about a nuke going off then the powergrid.
Yes, it will in addition to the diodes the solar cell itself is nothing more than a large PN Junction photodiodes themselves that put out a small amount of energy, that when teamed up with others in the panel make enough current to make usable power.
What causes the large voltage spikes are long conductor runs; longer conductor runs means more induced voltage from the EMP; the voltage causes damage either by exceeding the limits of the insulators (wires, capacitors) or the junctions (diodes, transistors, other semi-conductors).
It’s a nightmare to protect them and probably easier to just use 30% or 50% of your panels, keeping the rest in protected storage.
I recently purchased a complete solar system (Solar Essentials….. something) from an online retailer (www.customsurvivalsolutions.com). It’s great because when the power goes out it’ll power my fridge long enough to maintain it’s chill, keeping my food safe and frozen foods frozen. Additionally, I can use it to power a small microwave and recharge cell phones, laptops, ipads, etc., etc. I keep the generator plugged in so it always has a full charge, but only bring out the panels when the power goes out.
My current understanding – from a fair amount of research (all of which is suspect to some degree or another )
