[RE-wrenches] Solar World shattered module

[Nick Soleil]

Hi David,

I've seen this a lot of times, and it was always caused by the diode
failing, which caused the diode to get very hot and would result in the
glass shattering.  This was often obvious because the area around the diode
would become black and the module j-box would sometimes begin to melt.

One time I was replacing one of these modules and burned my finger on the
glass near the diode.

“Don’t get me wrong: I love nuclear energy! It’s just that I prefer fusion
to fission. And it just so happens that there’s an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it’s wireless!”

- William McDonough
