I can tell you that we have done "out of the box" and "installed for 6
months" and "installed for 3 years" testing on a number of single crystal
modules....In general, most met the spec sheet fine print stating "plus or
minus 10%"....Sorry to say, none of them were "plus".  Most results were
more like 7 -8% below nameplate.  No significant degradation over the time
periods tested.

Our comparable testing of amorphous has shown sharp wattage degradation in
the first 6 months then stabilized to about 15% max below the "out of box"
initial IV curves.  Post stabilization results have been level.  The
advantage to the amorphous has been that the "out of the box" results have
been high enough above the nameplate ratings to compensate for this.

We will have some Real World comparative data in the not too distant future.
By this fall, I hope.  Will be happy to share when it's done.
