PV System Efficiency under Various Conditions by Monitoring the MPPT

Abstract

To determine the efficiency of photovoltaic (PV) systems, the paper proposes a method based on the location of the Maximum Power Point (MPP) and on the principle of dividing the power-point curve into uniform segments. The algorithm detects exactly the highest MPP in the power curve, which was compared to other MPPT algorithms and standard Perturb and Observe (P&O) for partial shading conditions. Also, a comparison between two test cell alternatives was made. The results show that a better shape board algorithm is provided. Acquired results, also, present that the higher output power was obtained from the standard PV system compared to other MPPT algorithms and with the P&O Standard.
