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.

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.
