Good question, though I doubt not being exposed to sun harms them much work

Most are rated for at least 80% of their initial output after ~20 years of use, so sitting in the box for a while won't really hurt them. Even then they aren't "dead" or completely useless, they just don't output as much as they did when new.

If you ever find yourself in a fair fight, your tactics suck.
