A computer system monitors the temperature of the solar panels remotely

Researchers Control and Robotics group at the University of Huelva ( Spain ) have developed a computer system that allows electronic , remotely and in real time, measure the surface temperature of each panel PV system , regardless of size , to pinpoint its actual performance . That is, in addition to detect faults, is able to recognize its operating point and whether or not it is ideal. Currently this procedure is done through regular site inspections by specialized operators. Specifically, the system is able to monitor the temperature of each solar panel so telematics, so that this process is a reduction of economic costs associated with the monitoring and maintenance of all types of PV system. Not influence the number of panels that compose (tens, hundreds or thousands) and lens implantation (domestic, commercial or research) . In photovoltaic systems is useful to know both the surface temperature of the panels as the solar radiation that strikes them. The objective is to determine, according to experts, the exact point from which to extract maximum power from a given panel, ie, the optimum operating condition. “Since both parameters can change continually throughout the day due to weather conditions, it is difficult to detect when the electrical power that is generated is correct or if there is some kind of failure , for example , hot spots that alter their activity "explains project leader, José Manuel Andújar , professor at the University of Huelva.

In their study, published in the journal Sensors, experts have developed an electronic and computer system capable of high precision measuring the surface temperature of photovoltaic panels. "This instrument allows the temperature individually or panel- -Panel to complete installation, in addition to providing ' alarms ' able to send automatic messages sent to mobile phones or likewise emails when any alteration occurs" says Professor Andújar. Also, the system developed by specialists also provides that each user can access the installation for telematics, in real time and from any geographical area. "These features make the system more cost effective, and to measure and display the temperature of each panel from all parts of the world where there is Internet access," he qualifies. To reach these conclusions, the experts designed and patented in the first place, an electronic sensor that allowed the measurement and subsequent visualization of the temperature of each of the panels through the computer screen or other device. "We then developed by algorithmic techniques, a system of easy implementation, free and suitable for storing, processing and comparing many -from temperature- measures simultaneously," said Andujar. Finally, the device was installed and successfully tested in the School of Engineering of the University of Huelva, where researchers reanalyzed their viability when monitoring the temperature of the dozens of panels

that make up the PV system. "This last test helped us to check in a real situation both the new system and access to it from different countries or continents," he adds.

One of the main applications that emerge from the study is able to contribute to those plans or aimed at promoting the implementation of photovoltaic systems subsistence strategies. "This system allows you to install and maintain a lower cost of household photovoltaic systems previously , due to their size and investment , were not viable given the high cost of maintenance they require periodic inspections " argues researcher. The development of this system has allowed researchers to open other lines of work for the development of new utilities for preventive and predictive maintenance, ie, a process in which the operator would only have to move the facility to repair any damage. "This new system would lengthen in a lifetime of photovoltaic systems, a considerable improvement in its profitability and greater care of the environmental conditions of our environment from the use of renewable energy," said Andujar.These results are the fruit of excellence project Integrated system for optimizing , monitoring and fault analysis in panels and photovoltaic arrays , funded by the Ministry of Economy , Innovation, Science and Employment of the Government of Andalusia.

Comentario

Por medio del nuevo sistema que han creado los investigadores del grupo Control y Robótica de la Universidad de Huelva (España) permitirá controlar y medir la temperatura de cada uno de los paneles solares que sean instalados, esto ayudara revisar exhaustivamente la temperatura de estos mismo y así evitar sobrecalentamiento o daños que provoquen la desinstalación de esta celda fotovoltaica.

El sistema tiene como objetivo determinar, el punto exacto a partir del cual se puede extraer la máxima potencia de un determinado panel, es decir, su condición ideal de funcionamiento, será muy provechoso por que se observaran los cambios continuamente a lo largo del día debido a las condiciones climatológicas, y así saber que tanto generar o cuanto puede soportar la transformación de la energía solar a energía eléctrica o en su defecto a energía térmica.
