Innovative and precise MPP estimation using P-V curve geometry for photovoltaics

The paper proposes an innovative and intelligent MPP finding method based on P-V geometry of a solar cell or a module using quadratic regression analysis. The method can determine the MPP precisely even though the measured data contains high noise. It is employed for different PV cells and modules and the MPP parameters obtained are in well agreement with those of reported in datasheet. The MPP tracking execution time of method is very small and it outperforms widely used P&O.
