best low light performance
Hi, Amorphous panels are clearly the best for low light performance--but are relatively speaking huge. Does any one know if Poly or Mono are better in low light?

One of the main reasons for early failure with all PV made by Unisolar is that the protective coating for both their rigid and flexable panels is plastic. UV destroys plastics, and it has to pass through that before reaching the cells.
Actually I think it's the other way around. I believe the plastic lense on the front of Unisolar units is heavily UV stabilized, resulting in the lower efficiency rating per square meter, because some of the light energy is absorbed by the stabilizing additive in the polymer coating.
