An Analytical Solution for Tracking Photovoltaic Module MPP

In this paper, a new method for estimating the maximum power point (MPP) of a solar array based on its characteristic equation is introduced. The proposed method is simple fast and returns the MPP accurately. Moreover, the sensitivity of the introduced scheme to the model parameters is analyzed. Finally, the practicability of the proposed method is demonstrated by both simulation and experimental results on REC-AE220 solar modules.
