I agree with stir crazy, putting the panels the OP described (320 watts 24 volts) in series, will easily be within the capabilities of the 10 gauge wire. I would only suggest buying panels with a higher voltage output. Two 37.5 volt panels in series is 8.33 amps. The higher voltage panels begin to output a voltage (suitable for charging your battery bank) sooner in the morning and later before sunset. As long as the solar controller is rated to handle the voltage output of the panels you’ll be ok.
