Voc is zero power (no amps), that's why 12v panel is Voc of ~21.
I understand that but don't know what kind of drop to expect to see with load on it and cuz i don't have a controller or any sort of load to hook up its the only measureable number i can get and sc amps from panels....I have individual cells as well and so i could measure individual output if numbers are wanted....i planned on making my own tailored to a 12 volt system but way better with already assembled panels just got to get that voltage down by either wiring or a fancy controller...
