hi cottagecamper, adding similar panels to each string increases voltage but current (amps) stays the same for the panel to controller wires. Voltage drop is based on amps so the calculated voltage drop would be the same, the voltage would be 60+v. 10g is adequate.
Between the controller and battery there will be an amp increase, use the largest wire that will fit the controller.
