Solar power station model in Matlab Simulink program

The paper outlines various factors affecting the solar module efficiency. The authors consider the dependence of the solar module operation on insolation and temperature. The temperature increases the degradation of the solar modules during the operation time, determines technical characteristics and the efficiency of the modules, which decreases as the temperature increases. Using the Matlab Simulink program the authors have developed a model of an autonomous solar power plant. The model considers the relationship between the heating temperature of solar modules and their efficiency during operation. The model provides an option of selecting solar module makes, the number of modules and their connection circuits. Depending on a solar module make the corresponding current and voltage parameters are automatically set. When the model operates, the batteries connected to the solar modules are charged and the inverter converts DC into AC.
