Repair of broken PV modules [RE-wrenches] How about Lightning Damage?

[Tom Lane]

Space shuttle damage !!   I was at a home when the space shuttle broke the
sound barrier twice coming in to Cape Canaveral. It will shake the whole
house when this happens.  Unfortunately the second vibration caught the
glass flexing up from the first boom and broke the sheet of glass.  We have
had customers calling us after sonic booms thinking the solar system somehow
blew up on the roof causing the sonic boom!
Happy Trails,
Gator Tom

PS I have pictures of a lightning strike going straight through 100 watt
siemens modules, blowing a hole in the middle the size of a fist.
