This paper presents the design and implementation of a closed-loop solar tracker system. The demand for clean energy sources has increased along with the rising demand for electrical energy and the increasing amount of environment pollution triggered by fuel consumption. Among these sources, solar energy is considered the most feasible given its wide availability and easy operation in different environments. The main purpose of this study is to maximize the generated photovoltaic power and reduce CO<sub>2</sub> emissions by designing an efficient and low-cost solar tracking system. An aligned closed-loop solar tracker is designed and constructed to achieve the best accuracy. The proposed system shows more freedom in its movement to overcome the problems associated with the tilt of the frame-holder. A PIC microcontroller based on the Flowcode programming language is used, the position feedback is detected by using a photo-sensor, and the H-Bridge driver is used to control two DC motors. According to the experimental results, the proposed system shows significant improvements in efficiency compared with stationary solar tracking systems.

Abstract The present work aimed to select the optimum solar tracking mode for parabolic trough concentrating collectors using numerical simulation. The current work involved: (1) the calculation of daily solar radiation on the Earth’s surface, (2) the comparison of annual direct solar radiation received under different tracking modes and (3) the determination of optimum tilt angle for the north-south tilt tracking mode. It was found that the order of solar radiation received in Shanghai under the available tracking modes was: dual-axis tracking &gt; north-south Earth’s axis tracking &gt; north-south tilt tracking (β = 15°) &gt; north-south tilt tracking (β = 45) &gt; north-south horizontal tracking &gt; east-west horizontal tracking. Single-axis solar tracking modes feature simple structures and low cost. This study also found that the solar radiation received under the north-south tilt tracking mode was higher than that of the north-south Earth’s axis tracking mode in 7 out of 12 months. Therefore, the north-south tilt tracking mode was studied separately to determine the corresponding optimum tilt angles in Haikou, Lhasa, Shanghai, Beijing and Hohhot, respectively, which were shown as follows: 18.81°, 27.29°, 28.67°, 36.21° and 37.97°.

AbstractThis paper describes the design of an advanced solar tracking system development that can be deployed for a range of applications. The work focused on the design and implementation of an advanced solar tracking system that follow the trajectory of the sun’s path to maximise the power capacity generated by the solar panel. The design concept focussed on reliability, cost effectiveness, and scalability. System performance is of course a key issue and is at the heart of influencing the hardware, software and mechanical design. The result ensured a better system performance achieved. Stability issues were also addressed, in relation to optimisation and reliability. The paper details the physical tracker device developed as a prototype, as well as the proposed advanced control system for optimising the tracking.

This investigation describes the design and implementation of a parabolic trough solar collector (PCC) with solar tracking to obtain hot water. The solar radiation available at the installation site is analyzed, followed by the design and construction of the mechanical system, making a series of calculations for the dimensioning of the reflective base, and a stress and deflection analysis of the structure is performed to verify the feasibility of the design in the ANSYS software. An analysis of the solar tracking system is performed, which is dimensioned from the PCC structure to determine the type of solar tracker to implement; The charging system, consisting of a solar panel and a battery, is dimensioned for the power supply of the tracking system; as a last point, for the heating system is determined the amount of water that is able to heat the system from the energy analysis at the installation site, the heating system is based on placing a Heat Pipe, in the focus of the parabola to receive the solar rays reflected by the collector and heat exchange to the water from a thermowell where the heat pipe condenser enters, finally tests are carried out in the PCC implemented obtaining a global efficiency of 16.37%.

This paper presents the design and development of a laboratory-scale single axis solar tracking system. The chronological method was implemented into the system because it has high accuracy and can save more energy as compared to other types of solar tracking system. The laboratory-scale single axis solar tracking system can be used to identify the suitable and safe workspace for the installation of the actual solar tracking system plant. Besides, the validity of the laboratory-scale single axis solar tracking system was examined experimentally. The angle of rotation, per hour is preferable to be implemented into the designed laboratory-scale single axis sun tracking system due to the high performance ratio which is 0.83 and can save the energy up  to 25% during sunny days.

Solar energy is a renewable and inexhaustible source, besidescausing damage to nature, being clean and sustainable.Transform the electromagnetic radiation emitted by the Sunelectrical energy are used solar panels. In order to improveefficiency and performance of this capture, a low-cost wasbuilt, a single-axis solar tracking system for photovoltaicpanels. The solution uses the automation Arduino UNO R3,open hardware, two photosensitive sensors LDR GL-5528, inaddition to a servo motor capable of moving the surface of aphotovoltaic plate according to the detection of the highestincidence of light. The circuit and its components wereprogrammed using the Arduino IDE software, version 1.8.11.As a result, it was possible to follow the movement of thesun, differing from a static panel, thus ensuring greater sunshineon the solar plate, as a result of this traceablecontrol prototype.
