Hi gang. I have a little more info on the comparison system that was being
discussed last week, just for the record.
I heard from the system installer (Roger) yesterday who filled me in. I really
do not know any more than the following:
1. Systems: eight 130 W Siemens and sixteen 64 W Uni-Solar
chances.

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 kep

Geoff,
When you mentioned "plenty of partial shading", that settled the issue
for me. Every cell in Uni-Solar modules have a bypass diode allowing
them to handle shading better than any other module I know of. For
potentially shaded areas or high ambient temperatures, it is our

From my own Unisolar installations, and many comments from installers
