[RE-wrenches] Hail

[George McClellan]

Good Morning;

Microcracks are a serious concern.  The damage has already occurred, but the results will not show up for a few years.  You should contact your module manufacturer and see what their recommendations are.  Based on the amount and size of hail, they recommend that the entire array be scrapped.

Adios,

George

Subject: [RE-wrenches] Hail

We had a pretty serious weather event and one of my clients had hail broken glass.  I advised him to request a replacement of the whole array or, if not, a module by module inspection for I-V curves and hot spots.  I am wondering if should reach out to other clients.  I don't want to be a storm chaser, but am concerned about micro-fractures.

Waddayallthink?
