Modelling of Silicon Solar Panel by MATLAB/Simulink and Evaluating the Importance of Its Parameters in a Space Application

This paper starts by describing a silicon solar panel model based on a comprehensive solar cell equivalent circuit. Then, as a case study, four similar modelled panels are considered in lateral sides of a satellite as its power source. Considering the panel model with different combinations of its equivalent circuit essential elements, the model operation is evaluated in a orbit attitude with some eclipse times. The variations in output characteristics of the panels due to changes in received solar irradiance and panels´ temperature are calculated for each equivalent configuration. The values of maximum generated power and total generated energy during a satellite typical period are compared for different spin rates. Finally, the best topology for panel equivalent circuit is stated based on the compared results.
