In this work, we review and simulate a dual-axis solar tracking system that used to produce electricity. The dual-axis solar tracking system increases the output energy of the solar panel by making the Photovoltaic panels tracking the sunlight, and by adding a cleaning arm that making the panel's surface free from dirt and environmental waste, which affect productivity. Therefore, in this work, we simulated the presented system using MATLAB and SolidWorks software and studied the weather conditions of Najaf city in Iraq, including the intensity of sunlight, temperature, wind speed, and cloud density, which is the study area of our work.
After studying the weather of Najaf city and analyzing the mathematical models, we selected the suitable main parts of the system, which including the photovoltaic panel, battery, charger controller, inverter, motors vertical and horizontal rotation, microcontroller, the base and the pillar or the column, the rubber wiper and DC motor, for the cleaning operation, and the Frame.
From the obtained results of MATLAB Simulation and after testing the system in different dates at 2019 and 2020 based on the weather of Najaf city, we conclude that the movement of solar panels is remaining stable throughout the year because the density of clouds is moderate in this city, and that leads the sun's movement to be stable.
Therefore, the use of the Open Loop sun tracking system model is very appropriate for Najaf city and this leads the system to be less complex and less costly instead of using a Close Loop model.
