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.
