Design and fabrication of a single-axis solar tracker using Delta PLC

In this paper, a closed-loop single-axis solar tracking system is designed and implemented using a simple and efficient method. The tracking method is performed on the basis of a PLC programmable controller operating based on receiving a controlled feedback. In this tracker, four LDR optical resistance sensors are used to detect the position of the sun, utilizing a stepper motor to move the tracking system from east to west. Solar trackers have a critical role in solar thermal collection and change their efficiency from zero to 100%.
