Simulation of photovoltaic concentration with Fresnel lens using Simulink MATLAB

Abstract

The development of experiments to convert solar energy into electrical energy in photovoltaic (PV) has been widely carried out. Simulation is one approach that is used to find out the initial data before conducting an experiment with the aim of minimizing errors, saving design efficiency, time and budget. Simulation is made by modeling mathematical equations to analyze the performance of PV modules. The equation model is made into a block diagram, then simulated by the input-output function in Simulink Matlab. PV used is a type of amorphous silicon (a-Si). The Sun spectrum is the AM1.5 G standard which is concentrated using Fresnel lenses at wavelengths of 400-700 nm. Photovoltaic parameters include intensity, temperature, construction and materials taken from module specification data. Calculation analysis of PV modules produces a maximum total power of 0.057 W with efficiency reaching 6.68 %.
