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?

You read into it more than was stated. I said there were better choises for efficiency than Thin film amorphous panels which have the worst conversion efficiency rating in the PV industry, nothing more.
I rated the different types using the industry standard tier scale.
I was asked about what type of solar panels I have and answered that I have The Sony Hybrid. I made no personal claim, mearly stated they have the highest conversion efficiency rating in the industry, which can be varified.

The consept of thin film technology is an exelent one and may yet prove to be the furure of PV. As presented in its current form it is the the highest cost per watt for the lowest return in output of anything in the industry, irrespective of available light.
If one wants to get very technical and dig into some interesting information, I suggest studying the affects of ambient temperature on PV panels.
Don't go there, thin film tends to do well ;) at least the Unisolars do (triple junction thin film, with each layer absorbing a different light frequency).

I feel its only fair to go there to inform others that there are better choises than thin film technology. Not only in "bang for the buck", but also in terms of efficiency, longevity, and power produced.
Are you aware that there are two types of thin film construction?
One uses a conventional frame and glass, and is the best of the two.
The other is what pianotuna has,flexable type, with the plastic coating that UV will deteriorate and has been the main issue.
It does not matter what the ability is to absorb light if the light can not get through the cloudy plastic layer.
