[RE-wrenches] Lightning Strike Fries Array

[Matt Sherald]

Hi Wayne,

Several years back I had all sixteen SolarWorld modules on a tracker get
zapped.  The two other trackers adjacent to this one had no damaged
modules.  The same strike blew out the phone box at the end of the road
(some distance away).

The SolarWorld jboxes were all sealed with no way to get to the diodes.
The homeowners insurance covered the loss and I replaced the modules with
something similar (SW had since stopped manufacturing 175s).  It would have
been nice to have had access to the diodes.
