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?
Forum Discussion
I did this for amorphous vs poly. This data is for a 1 m^2 panel at low irradiance.
Power output at 200W/m^2
Unisolar: P = 200W * 8% = 16W
Siemens: P = 200W * 12% = 24W
Kyrocera: P = 200W * 11.2% = 22.4W
BTW, Don's US64 has 1 m^2 area. And that's the same size as a 135W Kyrocera.
Comparing those two panels, we get:
*************** US64 *** 135W Kyrocera
Max Power ** 64W *** 135W
Low Light **** 16W *** 22W

All we need now is the size of the panels to be stated in m^2.
We know that Amorphous panels are huge. What we need to know is what happens if we use the same m^2 size for Amorphous, Mono or Poly.
Which gives more Watts per roof real estate at low irradiance? :)
