[RE-wrenches] Microfractures in PV Modules

[Christopher Warfel]

Recently a inspector raised the issue of microfractures in pv modules, 
and that the existence of such fractures would require replacement of 
the modules and a failing of the system inspection. I found information 
from NREL confirming the existence of microfractures in poly 
crystalline.  However, I have not seen any information on how to detect 
them (ie, what they look like).  Does anyone have a reference that shows 
this, and is this a valid concern for the industry?  Thank you, Chris
