Influence of local shadow on output of photovoltaic array

Abstract

Abstract This paper first deduces the engineering mathematical model of photovoltaic cells, then builds the photovoltaic cell and photovoltaic array model in Matlab/Simulink, and then simulates and compares the output of photovoltaic array under the condition of series and parallel connection, the number of shadows and shadow distribution. Finally, the different effects of shadow in series and parallel and the influence of shadow distribution on the output of photovoltaic array are analyzed.
