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,
Misleading information, panels intended for charging a 12 volt battery are never 12 volts. Very optimistic numbers. Even worse if pwm is used. MPPT has conversion losses of between 2 and 4%, and losses increase as input voltage rises.harold1946 wrote:
Watts = amps x volts. cant have one without the other.
a 12 volt, 256 watt panel is capable of producing 21.3333 amps maximum.
12 volt, 460 watts will produce 38.3333 amps maximum.
How is it misleading? the formula is the same, just change the volts to Unisolars spec of 16.5 volts and calculate for 256 watts.
256/16.5 = 15.5151 amps maximum. at peak output. Or what ever voltage trips your trigger.
