Does this suggest that it is better to buy monocrystalline cell modules instead of poly; and that those modules that flash test with the highest output for a given production run have the best printed connections and therefore the higher probability of long term life and performance?

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 -- Christopher Warfel, President ENTECH Engineering, Inc.
