Improving the performance of solar panels by the used of dual axis solar tracking system with mirror reflection

Abstract

This work proposes the dual axis solar tracker with mirror reflection for optimum output of solar panel by using arduino unoR3 as the control unit. The objectives of this work are to track and optimize the maximum output power of the solar panel by designing and developing a dual axis solar tracker with mirror reflection. The system includes a 10 watt solar panel, an arduino unoR3 and a customized mechanical body to carry the solar panel. This system will track and detect the angle of the sun to locate the surface of solar panel at the position and the angle where it can get maximum amount of energy. The sensors will detect the position of the sun and servo motors act as free moving neck to make it easier to move freely depending on the angle detected. The Light Depending Resistor (LDR) will be used in tracking system. These LDR will detect the existence of sunlight and therefore the mechanical hardware will move horizontal and vertical axis depending on the value of LDR detected to follow the angular degree of sun in order to get maximum and best result of absorbing energy. The final result obtained from dual axis solar tracker showed that the output power has been maximized compared to stationary panel. Based on the experimental result, it show that the designed system successful improve the performance of the solar panel.

Performance Comparison between Fixed and Dual-Axis Sun-Tracking Photovoltaic Panels with an IoT Monitoring System in the Coastal Region of Ecuador

“…From these groups, the most common classification is according to their degree of freedom [12]. Single-axis solar tracking was the first technology used to follow the sun's daily motion.…”

“…Both motors are commanded by a TB6600 stepper motor driver controller [27], and this is in turn connected and controlled by the Arduino module. The loop is closed by four Light Dependent Resistors (LDR) used to evaluate the sun's position and accordingly move the solar positioning system, as suggested by the authors in [12] and [28].…”

“…The literature provides many studies regarding the use of solar tracking systems capable of following the trajectory of the sun throughout the day on a year-round basis [10,11]. The solar tracking system is one of the most suitable methods to increase solar panel efficiency by controlling the orientation angle (azimuth) and elevation angle (zenith) of the PV system [7,12]. The azimuth is the compass angle of the sun, which moves from east to west over daytime, and the zenith is the angle of the sun looking up from the horizon or ground level (it varies throughout the day, roughly 0° at sunrise, 90° at midday, and 180° at sunset) [13].…”

Design of solar cell using mirror, cooling, double axis, and solar tracking

“…With a reflector and without cooling, the efficiency increased by 32%, and efficiency increased by 52% with reflector and cooling. Further, Ismail et al [14], in his research entitled " Improving the performance of solar panels by the used of dual axis solar tracking system with mirror reflection," said that solar cells with mirror reflections produce high output power and provide better and more efficient performance. Considering the above, the author tries to design a solar cell device using a mirror, cooler, and a microcontroller-based dual-axis solar tracking device that seeks to increase the solar cell's energy output.…”
