    Connect them in series, this will increase the voltage to the controller but keep the current, and hence the power loss in the cable the same.

    The controller you have can take a maximum PV voltage of 150V. Each panel, assuming they are "12 Volt" (36 cell) panels will have an open circuit voltage of 22 to 23 Volts, two in series will be around 45 Volts, no problem for you controller.

    Use 6mm2 cable and be sure to connect the battery to the controller and make any configuration changes before connecting the panels.
