Abstract

In this paper a control algorithm for battery charger from a solar panel is proposed. This approach takes advantage of the maximum solar radiation received on the solar panel in the early and late hours of the day, because the control algorithm provides the optimum programmed current to the battery in these hours. In order to study and quantify the benefits of maximum current of charge tracking, the control algorithm constantly samples the solar panel output current-voltage under sunny sky conditions. Experimental results of the control algorithm implemented for fixed horizontal solar panel are presented.
