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?

Pianotuna made the statement that "amorphous panels are clearly the best for low light performance." I am still waiting for anything that supports that statement.
Anyone knowledgable of PV knows thin film cells produce less power per square foot at a much higher initial cost than conventional panels. Their industry tier rating is #5, making them the least efficient PV produced.
You are only looking at the footprint comparison, not what it can do for you in low light. I have nearly 200w more than Tuna does yet he gets more amps in low light than I do. Get a week of cloudy weather and I'd rather have his because they would keep us off the generator and ours will only delay it's running.
Now do you understand?
:)All PV panels are tier rated for efficiency (the ability to produce a given amount of power from a given amount of light). The highest rating being tier #1. Unisolars'thin film is rated tier #5, the lowest on the scale.
Now do you understand ?
When did you test what he claims?
His panels are made by Unisolar. They are ("thin film", amorphous technology).
It would make no sense to replace what is claimed (by him) to be superior with something inferrior. If they are truly better, would they not also be superior under all conditions, not just low light?
If what is being claimed is fact, where is the supporting documentation?
