The effect of input current ripple on the photovoltaic panel efficiency

This paper presents the effect of the input current ripple on the photovoltaic source efficiency. The input and output current can be either continuous or discrete, with or without ripple, giving either continuous or discrete energy flow hence affecting the input source efficiency or the output load application. This paper considers the influences of the converter input current ripple on the photovoltaic module and the loss of power extracted, in conjunction with converter efficiency, thus losses in the overall system efficiency. With input current (or voltage) ripple, there is no maximum power point; instead, there is maximum power track or locus curve. When the input current ripple reduces to zero, the maximum power curve becomes a point, specifically the DC maximum power point.
