Performance simulation method of half-cell PV module under shadow shading
The photovoltaic(PV)module slicing technology is an effective method to improve the module power,but the change of the structure brings some difficulties to the modeling of PV module output performance under complex situations.In this paper,a performance simulation method for half-cell photovoltaic module under shading conditions is proposed.To simulate the output performance of half-cell PV module under shading conditions,the method is based on the single cell and combined with the series and parallel structure of the equivalent circuit.Finally,four different shading experiments are used to verify the accuracy of the algorithm.The average deviation between the measured values and the calculated power of the PV model is 2.42%,which proves that the method has high accuracy.In addition,the output performance of half-cell and full-cell PV module under different shading conditions is compared.The results show that half-cut PV module have more obvious advantages than full-cell module under most shading conditions.
