just went outside and threw meter on panels
60 cell made 37 volts and 6.8 amps
72 cell mix and match made 45 volts and 9.5 amps
all voc an isc but pretty decent on cold but pretty sunny day
that's 251 watts for 60 cell
and a whopping 427 watts for 72.....if that's right that's nuts
That's zero watts Isc and zero watts Voc. See graph! ;)
Hooked to a battery @ 13v, 9.5A x 13v = 123 watts.
okay so directly hooked to battery amerage remains same while voltage drops...now i get it....and i assume an mppt controller will give me allot more then that as it reduces voltage and increases amps??
