Performance analysis of PV module connected in various configurations under uniform and non-uniform solar radiation conditions

Abstract

This paper focuses on investigating the I-V and P-V characteristics of a PV module connected in various configurations. Here the parameters of the PV module have been obtained from the datasheet. The performance analysis of PV module has been carried out under uniform and non-uniform conditions such as change in irradiation, change in temperature, accumulation of dust and change in wind forces using MATLAB-Simulink environment. From the obtained results, it has been observed that for a given number of PV modules, the array configurations affects the maximum available output power where more local maxima are found under partially shaded conditions. Moreover the comparative analysis of PV module has been performed under various configurations like series, parallel and series-parallel for the above disturbances condition. From the above analysis it is evident that even under non-uniform conditions, the parallel arrangement of PV modules is more prominent were maximum output power is obtained and the results are reported.
