[RE-wrenches] Extensive Lightning Damage to Modules

[jay peltz]

My 2 cents here is that this is flash irradiance damage.

As there appear to be no "burn" marks on the module frames right?

At the time, we thought it might be a disgruntled employee because no one had ever heard of such damage. I think we used box lugs and star washers on each module back then). the second just a few weeks ago. this time it seemed totally random affecting about 30% in different strings. Seems back in the broadcast industry we viewed lightening strikes as "Acts of God", and focused more on repair than the "whys". We install as per manufacturer's spec and NEC, and cross our fingers.. But when the Good Lord comes knocking, all bets are off. I remember pulling onto a job site once and found 80 lb chunks of chimney/ fireplace some 150ft down the driveway. Yes, the house did have lightening rods. Good Luck. db
