Are Solar Panels in Your Plans?

When in comes to all things solar, I am a novice.  I have a very basic set-up from Harbor Freight that is used for light duty power in my garage but other than that, I have a long way to go.  So when I was asked the question, “Will solar panels survive an EMP?” I was stumped.

First of all, no one really knows what will or will not survive a massive EMP such as the type in the hugely popular book, One Second After.  Second, and more to the point, I am not well versed on the technical side of electronics even though I am a techy nerdy type when in comes to computers.

Faced with a good question and no answer, I turned to my long time friend, George Ure, who I have known since 1971.  George writes a popular news and economics column at is also the author of Peoplenomics.  He is an absolute whiz at this stuff so I turned the question over to him.

The answer to EMP protection is fairly complex, as you might imagine.

EMP is a pulse of energy created by an atomic or chemical blast under highly specialized conditions.  The easiest way to create it is to set off a fairly high yield atomic blast above the Earth’s atmosphere.  Gamma radiation, upon striking the upper atmosphere, sets off the pulse which is about one-third the length (or smaller) than the duration of a lightning strike.

In the analysis of EMP damage, one needs to look not only at the device itself (the solar panel) but you also need to take into account the peripheral equipment and wiring.  A solar panel itself may be inherently resistant to EMP to some extent.  But, if damage occurs, it is likely due to the wires between the solar panel and (most often) the…
