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...
I don't think your panel will output much more than a battery's voltage connected directly. That'd be 30v drop or so!
You become the controller and loose lots of power or buy a MPPT.
