Electrical energy generation model of photovoltaic systems

As the development level increases day by day it brings the rise in the energy requirement with it. To satisfy the need of this energy, instead of limited sources such as coal and gas, renewable energy sources have come into use. Being one of the renewable energy sources, solar energy is mostly prefered due to its extensive practice field, ability to gain without using much effort and money. Understanding solar energy systems have big importances in using these sytems with efficiency. In this thesis, a modulation for photovoltaic systems is done in MATLAB/Simulink environment. The simulations are performed by considering the irradiation and temperature effects. The modulation consists of; a maximum power point tracker, battery system, DC-DC boost converter, DC-DC buck converter and photovoltaic panel. The parameters of the panels in markets are used in the simulation and the obtained results are compared with the datasheet results. The comparison results have shown high efficiency. Real time measurements are taken from the installed setup and it is seen that the results are compatible with the simulation results.
