The low efficiency of solar panels, ranging from 20-24%, remains a major problem in their utilization. Numerous efforts have been made to address this issue. One approach is the use of solar trackers on solar panels to maximize sunlight exposure, thereby increasing their power output (Pout) and efficiency. Conversely, the use of concentrators is also an alternative solution to increase the light intensity reaching the solar panels, thereby increasing their Pout. Research shows that using a concentrator on a laboratory scale can increase Pout by 24.31 mW/cm2 compared to a solar panel without a concentrator, which only achieves 4.25 mW/cm2. In this study, a prototype dual-axis tracker for a concentrator on a vertical solar panel in a Concentrated Photovoltaic (CPV) system was successfully developed. The dual-axis tracker system was mounted on the concentrator to support the concentrator's movement in reflecting sunlight onto the solar panel in a vertical position. The threshold method was used to drive the DC motor on the horizontal axis. The scanning method was used to determine the optimal light point for controlling the servo on the vertical axis. This system is also equipped with IoT (Internet of Things) for real-time monitoring. Results show that the dual-axis tracker system performs well and can increase Pout by around 26.3% (46.20 Wh) compared to a vertical CPV without a tracker (43.39 Wh). This system can also be monitored in real time using the IoT feature.
