Electricity production from solar panels is improved by maximizing their capture of solar radiation by tracking sunlight so that it falls perpendicular to the panels. Pneumatic actuators are useful te...chnology for pointing panels toward the sun. They are an alternative to hydraulic actuators, which are maintenance-intensive, leakable, and require many associated components. Electric actuators are large, not suitable for all conditions, and have a high initial cost. Two pneumatic actuators were employed in this paper to drive a two-axis sun tracker. The proposed tracking method provides wide freedom of movement, greatly simplifies the tracking mechanism, possesses many advantages that come with pneumatics, like reducing consumption, costs, environmental risks and the need for ongoing maintenance. This paper aims to provide a comprehensive design of pneumatic actuators to drive a two-axis solar tracker that operates as efficiently as possible, taking into account the maximum load in the worst possible weather conditions in Iraq. This entails determining the piston cylinder length and inner diameter based on certain input parameters such as stroke, fully extended and retracted lengths, and force of the cylinder, impact angles, and wind speed. To examine the actuators' performance, a MATLAB simulation was run on March 1, 2024, in Baghdad-Iraq, on a typical sunny day. The findings showed that when loaded under the greatest wind speed that can occur, roughly 5.5 m/s based on Iraqi climatic statistics, the proposed tracker operates precisely, steadily, and smoothly. Ultimately, the design procedure used 150 mm length pneumatic cylinders to drive the solar panel. Furthermore, at a static inlet pressure of 2 bar for actuators, it was discovered that actuator 1's cylinder diameter measured 22 mm, whereas actuator 2's measured 28.15 mm. Aligning the pneumatic actuators on two axes improved the efficiency of the solar panel by 66.4% when compared to a fixed panel.続きを見る
