Abstract:

In this study, the working principle, components and connection types of the solar cell and the equivalent circuit model extraction were examined. The mathematical equations of the photovoltaic (PV) solar cell module general equivalent circuit model were adapted to the MATLAB software. An interface was created in the MATLAB GUI environment using the Newton-Raphson method to solve the current equation of the solar cell. The model used also includes changing environmental conditions such as solar radiation and temperature. With the interface created, the user; can quickly obtain Current-Voltage (I-V) and Power-Voltage (P-V) curves by changing parameters such as radiation, temperature, series resistance, ideality factor and number of cells connected in series-parallel. In this study, characteristic curves were obtained by using different parameters for the solar panel data of two other manufacturers. In addition, the user can quickly get values such as maximum current (Imp), maximum voltage (Vmp), maximum power (Pmp), input power (Pin), filling factor (FF) and efficiency (η) by entering the variable values of the photovoltaic cell through this interface. In this way, an interface that provides convenience to the user has been developed for those working in this field.
