Sun Position Simulator for Solar Cell Testing and Characterization

The paper describes a Sun position emulator. The design and implementation of the Sun position simulator is presented in the paper. A Sun position emulator is a very useful tool for research and education. A solar panel have a fixed position, but the Sun will have a daily trajectory from East to West. The elevation of the Sun in the middle of the day will vary from winter to summer. The optimal position, related to the Sun, of the photovoltaic panel can be determined with the proposed equipment. The position of the photovoltaic panel is very important in order to extract the maximum power from the photovoltaic panel.
