“…The tracker senses the sunlight intensity via Light Dependent Resistors (LDRs) to be utilized for driving stepper motors to direct the Photovoltaic (PV) panels according to the sun position. Pineda and Arredondo [5] designed and carried out a two axis sun tracking system. The tracker senses the peak brightness light point in the sky by building a sensor based on a geodesic dome.…”

The present work presents design and implementation of an automated two-axis solar tracking system using local materials with minimum cost, light weight and reliable structure. The tracking system consists of two parts, mechanical units (fixed and moving parts) and control units (four LDR sensors and Arduino UNO microcontroller to control two DC servomotors). The tracking system was fitted and assembled together with a parabolic trough solar concentrator (PTSC) system to move it according to information come from the sensors so as to keep the PTSC always perpendicular to sun rays. The experimental tests have been done on the PTSC system to investigate its thermal performance in two cases, with tracking system (case 1) and without tracking system (case 2). The experimental results showed that the average solar radiation falling on the PTSC prototype in the two cases during the same time was 854 and 701 watt/m2, respectively, which means an increase in the solar radiation about 21.8 % when using tracking system. It was found that the average useful heat gain output of solar collector was equal to (376.2, 252.6 watt) for the two cases, respectively, so there was an increase of about 48.9 % when using the tracking system. Also, the average thermal efficiency of the PTSC was found to be (20.7, 26.5 %) for the two cases, respectively, which means an increase in the average efficiency by 28% with use of tracking system compared to the fixed case.

“…Scholars have conducted extensive research to it ,which the solar tracking strategy and the choice of system control unit, the literature [1,2] finish the solar position calculation and other control functions use micro controller. On the premise of guarantee accuracy reduces the cost of development, the literature [3] achieve roughly solar track with micro controller as the controller. At present lots of solar automatic tracking control system using visual trajectory tracking combine with photoelectric sensor tracking strategy, the literature [4,5] use photosensitive resistance sensor combined with solar trajectory tracking control strategy, the literature [6] use the silicon photocell sensor combined with solar trajectory tracking control strategy, the literature [7] use the panoramic image processing methods combined with solar trajectory tracking control strategy.…”

This paper presents a novel solar tracking trajectory calculation method, and addresses the problems of low efficiency, computing complex issues of solar tracking control system. Based on the Lagrange interpolation method, the solar trajectory is calculated by using the location information in certain times (day, month and year), and then the sun can be accurately tracked with the method of photoelectric tracking. Finally, simulations are preformed with MATLAB to verify the validity of the proposed method.
