[RE-wrenches] crystalline VS uni-solar and beyond

[Doug Wells]

How about the longevity?
This is the one area that has not been tested.
Crystalline cells have proven their longevity for the most part.   
Their weakness seems to be sealants and gaskets more than cell  
longevity.
How will the amorphous panels be producing in 20 years?
Is this why Sanyo has kept its warranty at 20 years for its cell  
design?(and I like their panels)
Thoughts?
