“…In reference [45], whose aim is to design a low cost two-axis solar tracker for obtaining a high precision positioning of the panel, the control-board is able to support different control strategy, PID and FLC; using the error signal, the tracking capacities of the proposed approaches are tested on an experimental prototype. In reference [12], the implementation of a fuzzy logic neural controller (FNLC) in photovoltaic systems has been studied; this controller, which is an evolution of the fuzzy control concept, allows the system to learn control rules. A controller which incorporates the advantages of two alternate design techniques (a deadbeat regulator for quick, rough control, and an LOG/LTR (Linear Quadratic Gaussian with Loop Transfer Recovery) regulator, for soft, final tracking) is presented in [35]; the first one performs approaching the target in a minimum of time; the second one allows a soft approach to the target.…”

This paper deals with a review on the solar trackers used for increasing the energetic efficiency of the photovoltaic (PV) strings. To begin with, the context from which the utility of the tracking mechanisms emerges is presented. The study continues with the systematization of the PV systems according to the structure that is oriented (i.e. the configuration in which the PV panels are disposed / arranged), presenting also the main advantages and disadvantages of the existing structures. Thus, it is retained as a solution for deepening the research that of the simultaneous orientation of the PV panels arranged in a string-like configuration. Afterwards, the study is focused on the main components that are taken into account in the design process of the tracking systems for PV strings, such as the tracking mode, the evaluation of the solar energy potential (involving the modelling of the solar radiation), the emplacement/disposing scheme of the panels in different array configurations, the mechanical and control devices of the solar trackers.

Solar energy is the raw material and main source for several applications of renewable energy systems; thus, knowledge about the intensity of solar irradiation is essential for efficiency of these systems. Electric energy sources capable of meeting the growing demands of society with minimal impacts to the environment and high efficiency have been object of research in the last decade. In this context, the conversion of sunlight into electricity through photovoltaic cells has become one of the most encouraged and used resources in the world. However, the most unpredictable factor, which hampers capturing solar irradiation, preventing a proper conversion of sunlight into electricity, is the presence of clouds in the sky. Many methods of tracking and prediction of irradiation were proposed to increase efficiency in the production of energy by photovoltaic cells. This article presents an updated review on the mechanisms used for tracking and irradiation prediction, and their respective methods. It begins with a brief review on photovoltaic systems and classification of its mechanisms. Then, it presents a detailed overview on the evolution of mechanisms and their corresponding methods for tracking and irradiation prediction. Finally, the authors conclude with an analysis of performance efficiency of the mechanisms and their corresponding methods presented, describing the pros and cons of the most significant proposals for tracking and irradiation prediction.

“…In the literature, we find many works focused on the knowledge of several astronomical and atmospheric quantities, whereas the use of these in algorithms makes the parameters difficult to implement when it comes to simple solar tracking systems [4]. A solar tracker can increase the efficiency of such equipment at any fixed position at the cost of additional system complexity [5][6][7]. There are many types of solar trackers of varying cost, sophistication, and performance [8,9].…”

Improvements and applications of Inertial Measurement Unit (IMU) sensors have increased in several areas. They are generally used in equipment that measures orientation, gravitational force, and speed. Therefore, in this paper, we worked on improving the performance of IMU in an application on solar trackers of the Kalman filter. This work illustrates the design of an autonomous device with astronomical control of a photovoltaic (PV) panel, allowing the optimization of the orientation/energy gain ratio. The device is based on two concepts at the same time, the modeling of the solar trajectory adopted by an algorithm which calculates continuously the solar angles (elevation and azimuth) and the approval of these by the IMU in order to sweep away any climatic fluctuations and thus allow an almost perfect adjustment relative to the perpendicular axis of the rays. The tracking system is based on two joints controlled by an Arduino control board. Experiments have shown a better performance of the two-axis device: the net energy gains can be around 34% with an additional 1.1% when the Kalman filter is applied.
