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?

Hi Tech; Semantics again??
Is the definition of good in an RV application different than say a residential one?
Common sense tells one that efficiency of all PV drops off as light deminishes and varies by latitude and angle of installation, atmospheric conditions, no matter what the materials used in construction.
But common sense does not say the drop off is equal nor linear across two panels or panel types.
Agreed, and I would also include different manufacturers.
Yes an RV application is quite different. The RV moves from place to place and is subjected to a much larger and less predictable variation in light level and orientation than a residential install, where you can understand say partial shading and design for it very specifically.
:S
You can call definitions semantics, but I say you are hiding behind semantics to try to do an apples to oranges comparison, claiming that it is semantics to point out that an orange is not an apple. After all, they are both fruit. They must be the same, right?

Sinse there are four individual types of panels there is no choise but to compare apples to oranges, unless one considers all types to be equally conversion efficient, which they are not.
The option is to go with the most conversion efficient or something less. It has nothing to do with being lenier nor the amount of "drop off."
Using your logic implies that conversion efficiency can increase with deminishing light, which is contrary to physics.
Unless definitions follow logic and laws of physics they are wrong, are they not????
