Buyer Guide

With a PWM controller, the power drawn from the panel is 5.2A * 13V = 67.6 watts. This amount of power will be drawn regardless of the temperature of the panel, provided that the panel voltage remains above the battery voltage. With an MPPT controller the power from the panel is 5.0A * 18V = 90 watts, i.e. 25% higher.
