Control of Single-Axis and Dual-Axis Solar Tracking System

This paper concerns with improving the overall output and stability of the solar system by Single-Axis Solar Tracking (SAST) and Dual-Axis Solar Tracking (DAST) by using MATLAB/SIMULINK package with the Arduino as the main control unit in the paper. This combination makes the system more powerful, helps in saving the panel and improve the output or productivity of solar power. The process of tracking makes the panel produce its maximum power all over the day because it makes the panel follow the sun where ever it goes. Voltage and power extracted from the panel will be greater than the stationary position generation depending on the type of tracking system. After finishing the work, it was discovered that: the dual-axis solar tracking system had improved the output of the stationary position by 3.3% and the single-axis solar tracking system had improved the output of the stationary position by 2.6%. The output percentage is low because we used an experimental cell which is not accurate, that is because our paper is not actually an improvement to the cell, but a system that controlling the cell. For the system, it proved its efficiency in producing more power than normal systems. And once using an accurate and capable cell, the output will be further improved, because using MATLAB, which made our system accurate in calculations, and able to analyze information in a better way.
