ABSTRACT

This chapter presents the design, development, testing, and implementation of a dual-axes tracker. The study also presents the technique of increasing the efficiency of the solar panel by changing the orientation with respect to the sun’s position using dual-axes tracker. Light-dependent resistors are mounted on the solar panel to track the movement of the panel. The movement of the panel is also controlled by two 12 V DC motors for each of the axis. Arduino microcontroller is used as the interfacing medium to control the motors. In order to determine the direction of rotation of motors, relay circuits are also used as motor drivers. The Wi-Fi module is used to monitor the entire process through the TOT. The results are evaluated throughout the day and are evaluated with and without the tracker. The performance of the developed system was experimented and compared with the static solar tracking system. This work further demonstrates that the dual-axis solar tracking system has a higher power generation compared to static panels. The experiments show that employing dual-axis tracking system 138under sunny conditions has resulted in an increase of the voltage generated by around 10% in the morning and evening but with no significant change during the afternoon. The proposed design is achieved with low power consumption, high accuracy, and low cost.
