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?

Performance per square foot, yes.
Performance per watt, no. On that graph all those different panels would have different wattages due to their differing efficiency per square meter. We normally compare a 100 watt poly to say a 100 watt mono. To do that with the information on this graph, you have to shift the curves to the standard test conditions that define what a 100 watt panel is. To do that, you have to shift all the curves vertically so they cross 1000 (standard testing illumination to define panel wattage) at the same point.
If you do this then follow the Unisolar line left, it rises when the others are all basically flat. It falls, but later than many, and starting from a higher point than all the rest.
