    What is the Vmp/Imp ratings of the panels (assume Vmp~17.5 volts?).

    What is the voltage rating of the battery bank (12/24/48volts)?

    How far do you want to run the wires from the array to the battery shed/charge controller?

    Roughly, were will the system be installed (nearest major city)?

    Do you have a choice of charge controller (I.e., 60 amp PWM, 80 amp Outback MPPT, etc.)?
