Para generar de forma eficiente energía eléctrica utilizando paneles fotovoltaicos es indispensable que estos sean instalados de forma correcta. Para ello, se pueden implementar sistemas de control de posicionamiento (seguidor solar) mediante un algoritmo de búsqueda del punto máximo de energía, lo cual sirve para mejorar la eficiencia del sistema. Por tal motivo, en el presente trabajo se analiza el diseño y la construcción de un sistema fotovoltaico con seguimiento solar de dos ejes. El objetivo es determinar la eficiencia de este sistema frente a uno estático. El seguidor solar construido cuenta con celdas independientes que actúan como sensores y alimentan a los motores encargados de girar el panel fotovoltaico tanto en el eje vertical como en el horizontal. Para la adquisición de la energía generada por los dos sistemas de paneles solares se utilizó la tarjeta Arduino Nano 3.0 y diversos módulos. Los resultados de las pruebas realizadas se examinaron mediante el programa computacional SigmaPlot y la comparativa de grupos (ANOVA) de una vía. Asimismo, se realizó una prueba de rangos múltiples, que emplea el método de comparación múltiple de medias de Tukey.Luego se confrontaron los datos recabados durante un periodo de 29 días. Los resultados demostraron que en ese lapso la eficiencia promedio alcanzada por el sistema con seguimiento solar fue de 33 %, mientras que con el sistema fijo fue de 26.28 %. Además, se observó que, durante las primeras horas de cada día, el sistema fotovoltaico fijo logró generar más energía eléctrica que el sistema fotovoltaico con seguimiento solar.

The Right

The use of fossil energy as an electric fuel causes the earth to experience global-warming. As a tropical country, Indonesia has great potential to develop solar energy as a substitute for fossil energy. Increased efficiency in capturing sunlight will further optimize the work of the Solar Power Plant (PLTS). One way that can be done is by making a solar tracker so that the Solar Panel can follow the direction of the sun's motion. Optimization Design The solar tracker uses dual axis using Proportional Integral Differential (PID) control tuned with the Imperialis Competitive Algorithm (ICA), which is expected to be able to get the right angle between the yaw and Pitch with Azimuth and Elevation Angle. The PID-ICA controller design is done using matlab software. For vertical and horizontal rotary axes it is expected to obtain the best PID-ICA constant, which in turn will affect the performance and optimization of the photovoltaic system. The best optimization results using ICA-based PID with a settling time value of 0.0906 s on the horizontal axis and 0.094 s on the vertical axis

This project shows a photovoltaic hybrid system (PHS) that follows the sun using electronic and mechanic devices and reduces the solar panel’s temperature with water in order to increase the energy obtained. The system was designed and implemented with a 1-axis solar tracker system and a water cooling system. PHS allows solar radiation beams to fall almost perpendicularly and decreases the temperature of the solar panel. Finally, its performance is compared against a traditional fixed photovoltaic system (FPS) oriented at 15° facing south. Experiments were made during only seven days in a year between December 1st and December 19th of 2017 in Guadalajara de Buga, Valle del Cauca, Colombia. Tests consisted of using the same electric loads at 20%, 40% and so on until 100% of the total power capacity of the solar panels. Results points out that electrical efficiency of the PHS increased 5.03% compared to the FPS on the same environmental conditions. Finally, PHS shows daily additional average power between 37% and 40% when it is loaded with electric loads at 80% and 100%.

The Given

The structural integrity and deformation-induced misalignment of solar radiation for a tracking photovoltaic (PV) system under self-weight is investigated using a finite element analysis (FEA) approach. Gravity is applied to calculate the stress distribution and structural deformation. Misalignment of solar radiation induced by structural deformation is also calculated. Moreover, to avoid damages caused by resonance, natural frequencies of vibration for the given tracking PV system are also determined. Strain changes are measured experimentally at two selected locations in the given solar tracker during field operation for comparison with the simulation results. A reasonable agreement between the simulations and experimental measurements is found such that the constructed FEA model is validated to be effective in assessment of the structural integrity for PV systems under self-weight. No structural failure is predicted for all components in the given solar tracker under the given loading condition according to the von Mises failure criterion. An agreement in the trend of variation of misalignment and resultant displacement of PV modules is found. Considering the effect of self-weight only, the maximum misalignment of solar radiation is of 0.275o at elevation angle of 45o when rotating the solar tracker from 0o to 75o. It is expected that such a misalignment value will not cause a significant degradation of power generation for a PV system. The range of natural frequencies of the first six vibration modes for the given PV system is from 3.85 Hz to 11.4 Hz.

Solar tracking systems allow greater efficiency of a photovoltaic system by continuously adjusting its position in relation to the sun, thus increasing the generation of electrical energy. The integration of photovoltaic solar tracking systems in a photovoltaic plant allows the energy needs of users to be met more widely in a smaller area. This integration is facilitated by the existence of technologies such as access to the Internet via Wi-Fi, which allows the development of systems to be included in the domain of “Cloud” and Automation 4.0. In this study, an "open circuit" solar tracker, the first of its kind designed in Brazil on a plant scale, was designed and developed, which runs the tracking algorithm in the service programmed in a PLC, which has a Wi-Fi module integrated. This study opens the possibility of integrating power generation systems in the Cloud domain, which among other things, allows constant monitoring of the system's behavior with Solar tracking

The Difference

The work deals with the optimal design of a single-axis solar tracker, which is used to adjust the daily position of a photovoltaic system in order to capture as much as possible solar radiation. The two main components of the solar tracker (the mechanical device and the control system) have been coupled (integrated) in the concurrent engineering concept. For assuring high stability and robustness, the control system is a cascaded two-loop employing LPF (Low-Pass Filter) controllers. The controlled parameter in the main (external) loop is the daily angle of the photovoltaic platform, while in the secondary (internal) loop the linear velocity in the driving actuator is monitored. The mono-objective optimization problem is described in the following way: to minimize the difference between the imposed and current daily angle (thus preserving a high energetic efficiency of the tracking system), considering the controllers’ gains as independent design parameters.

The paper substantiates the need for the introduction of solar tracking systems for photovoltaic plants and presents a brief review of the scientific and technical literature on the development of solar trackers. Principal scheme of a heliostation with a dual-axis solar tracker of Orenburg State University has been designed. A comparative analysis of the generated electricity by a statically located solar module and a solar module with the dual-axis solar tracker is represented. Data for analysis have been obtained in Orenburg (Russia) using the developed automated system for remote diagnostics and monitoring of photovoltaic system parameters and a wireless weather station HP2000. The use of a dual-axis heliotracker for the solar plant in the conditions of the Southern Urals has allowed to increase the generation of electricity by 34.7% compared to a statically located PV panel.

Solar tracking systems enable increased efficiency of a photovoltaic system through a continuous adjustment of its position with respect to the sun, thus increasing the generation of electrical energy. The integration of photovoltaic solar tracking systems in buildings and houses enables the energy needs of users in a broader way to be covered. This integration is facilitated through the existence of technologies such as access to the Internet through Wi-Fi, which allows developing systems to be encompassed within the domain of the “Internet of Things” (IoT). In this study, a first-of-its-kind “open-loop” solar tracker was designed and developed, which executes the tracking algorithm in the Firebase web service and allows the exchange of data with said service through a NodeMCU development board, which has an integrated Wi-Fi module. After an experimental campaign in Aguascalientes, central Mexico, gains in terms of collected energy on average were measured at 29.9% in May compared to an optimally tilted fixed photovoltaic system. This study opens the possibility of integrating power generation systems into the IoT domain, which, among other things, allows for constant monitoring of the behavior of the system.
