De acuerdo con otra de las características de la invención, se ha previsto que opcionalmente el dispositivo cuente con un elemento de sombreado consistente en una visera anular, a fin de realizar una captación difusa de la luz, en orden a determinar las componentes de la radiación por separado en una trayectoria determinada del sol.According to another of the characteristics of the invention, it is provided that the device optionally counts with a shading element consisting of an annular visor, to in order to make a diffuse collection of light, in order to determine the radiation components separately in a determined path of the sun.

A la vista de las figuras reseñadas, y en especial de las figuras 1 y 2, puede observarse como el sensor de radiación solar que se preconiza está constituido a partir de una estructura (1), que configura una superficie semiesférica, bien de naturaleza metálica o plástica, que en el ejemplo de realización práctica elegido está obtenida a base de tres anillos (2), (2') y (2'') de diámetros decrecientes y situados a diferentes alturas y un conjunto de semi-anillos (3), dispuestos verticalmente y equiangularmente distribuidos que configuran una estructura reticular, en cuyos nudos de unión (4) se establecen células calibradas de silicio (5), de manera que en el conjunto participen al menos 29 células.In view of the figures outlined, and in of figures 1 and 2, can be seen as the sensor of solar radiation that is recommended is constituted from a structure (1), which configures a hemispherical surface, either metallic or plastic nature, which in the embodiment chosen practice is obtained based on three rings (2), (2 ') and (2 '') of decreasing diameters and located at different heights and a set of semi-rings (3), arranged vertically and equiangularly distributed that configure a reticular structure, at whose junction nodes (4) are established calibrated silicon cells (5), so that in the whole At least 29 cells participate.
Tal y como se puede observar en la figura 3, a cada célula (5) está asociado un sensor de temperatura (6), de manera que las señales tomadas por ambos elementos son enviadas a un sistema de adquisición de datos (7) tal como un ordenador o elemento similar, para su estudio e interpretación, previa etapa de amplificación (8). Esta etapa de amplificación es imprescindible debido a que las células (5), de silicio, originan una señal de baja intensidad que es necesario amplificar.As can be seen in Figure 3, a each cell (5) is associated with a temperature sensor (6), of so that the signals taken by both elements are sent to a data acquisition system (7) such as a computer or similar element, for study and interpretation, previous stage of amplification (8). This stage of amplification is essential because the silicon cells (5) originate a signal of Low intensity that is necessary to amplify.
De ésta manera, y si bien en el ejemplo de realización práctica elegido no se cubren todos los ángulos que puede formar la radiación solar (R) con los sensores o células (5), mediante algoritmos matemáticos y las señales provenientes de las diferentes células (5) se podrá obtener todo el espectro de la radiación desde el cielo hasta cualquier punto del suelo, con orientación e inclinación determinada, de forma semiesférica, así como controlar las derivas (térmicas, del coseno, offset, etc.) y amplificar las señales.In this way, and although in the example of chosen practical realization not cover all the angles that can form solar radiation (R) with sensors or cells (5), through mathematical algorithms and the signals coming from the different cells (5) the entire spectrum of the radiation from the sky to any point on the ground, with orientation and inclination determined, hemispherically, as well how to control drifts (thermal, cosine, offset, etc.) and amplify the signals
La asociación de un sensor de temperatura a cada célula (5) obedece al hecho de corregir los errores de medida que se dan en las diferentes placas, debido a que éstas en ocasiones alcanzan una temperatura diferente a la existente durante su calibración en fábrica.The association of a temperature sensor with each cell (5) is due to correcting measurement errors that they occur on the different plates, because these sometimes they reach a different temperature than the one during their factory calibration
Para posibilitar medir las diferentes componentes de la radiación, discriminando la radiación global, difusa y directa, y tal y como se puede observar en la representación de la figura 4, se ha previsto la participación de un elemento de sombreado (9) consistente en un cuerpo a modo de semi-anillo, dotado de medios de posicionamiento estable regulable, de manera que el mismo puede ser situado de forma manual, por un operario encargado a tal efecto, o bien puede estar dotado de medios de accionamiento electro-mecánicos, no representados en las figuras, en orden a automatizar dicho proceso tras una señal de control generada por el sistema.To enable measuring the different radiation components, discriminating global radiation, diffuse and direct, and as can be seen in the representation of figure 4, the participation of a shading element (9) consisting of a body as a semi-ring, equipped with positioning means stable adjustable, so that it can be located manually, by an operator in charge of it, or you can be provided with drive means electro-mechanical, not shown in the figures, in order to automate said process after a control signal generated by the system.
Dicho elemento de sombreado únicamente deberá estar cubriendo las células (5) sometidas a una mayor radiación solar a lo largo de una trayectoria diaria.Said shading element should only be covering the cells (5) subjected to increased radiation solar along a daily path.
Por último cabe mencionar que, como es evidente, la citada estructura (1) incorporará medios (11) para su fijación estable al suelo o al elemento de que se trate.Finally, it should be mentioned that, as is evident, said structure (1) will incorporate means (11) for fixing stable to the ground or to the element in question.
Se consigue de esta manera un dispositivo sencillo, de reducidas dimensiones y fácilmente implantable en cualquier instalación de paneles solares, sean del tipo que sean.A device is thus achieved simple, small in size and easily implantable in any installation of solar panels, be the type that be.
