Abstract
Seguidor solar caracterizado por tener una estructura circular dispuesta en retícula, con posibilidad de giro de 360º en ambos sentidos, a través de roderas e impulsado por trenes de avance (3) accionados por servomotores con reductor y ruedas guía (9) y apoyada en un eje central de giro (10). Los captadores solares elegidos, se disponen en filas (8) sobre las estructuras horizontales (2). Situados perpendicularmente en el eje horizontal, existen unos actuadores-empujadores lineales (4) que se deslizan bajo perfiles de tracción (5), permitiendo el abatimiento de los captadores solares entre 0º-90º. Con lo que se garantiza la perpendicularidad de la radiación solar y se maximiza la captación solar. Dispondrá además, de un sistema de seguridad basado en una estación meteorológica, que bloqueará las filas de captadores (8) tumbando los captadores en rachas de viento y posicionándolos verticalmente para acumulación de nieve.Solar tracker characterized by having a circular structure arranged in a reticle, with the possibility of 360º rotation in both directions, through rodents and driven by feed trains (3) driven by servomotors with reducer and guide wheels (9) and supported by a central axis of rotation (10). The chosen solar collectors are arranged in rows (8) on the horizontal structures (2). Located perpendicularly on the horizontal axis, there are linear actuators-pushers (4) that slide under traction profiles (5), allowing the solar collectors to fall between 0º-90º. This ensures the perpendicularity of solar radiation and maximizes solar uptake. It will also have a security system based on a meteorological station, which will block the rows of collectors (8) by knocking the collectors in wind gusts and positioning them vertically for snow accumulation.

La presente invención se refiere, tal como expresa el enunciado de la presente memoria descriptiva, a un seguidor solar del tipo que a través de sistemas que siguen la trayectoria del sol, se utiliza para mejorar la producción de los paneles fotovoltaicos captando la máxima radiación de energía solar durante el mayor tiempo posible aportando a dicha función una serie de características y prestaciones novedosas y mejoradas, respecto a lo ya conocido.The present invention relates, as expresses the statement of the present specification, to a solar tracker of the type that through systems that follow the trajectory of the sun, is used to improve the production of photovoltaic panels capturing the maximum solar energy radiation for as long as possible by contributing to this function a series of new and improved features and benefits, with respect to I already know it.
Más concretamente la invención consiste en un seguidor solar, cuya estructura es circular, capaz de albergar mayor número de captadores solares aprovechar la superficie destinada al máximo. Minimizando el mantenimiento de las instalaciones y consiguiendo el mayor rendimiento posible tanto productivo como económico y medioambiental; en el menor espacio posible.More specifically the invention consists of a solar tracker, whose structure is circular, capable of housing greater number of solar collectors take advantage of the surface destined to the maximum. Minimizing the maintenance of facilities and getting the highest possible performance both productive as economic and environmental; in the smallest space possible.
Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación e instalación de paneles y estructuras destinados al aprovechamiento de la energía solar.This invention has its application within the industry dedicated to the manufacture and installation of panels and structures intended for the use of solar energy.
Como es sabido, los seguidores solares se utilizan para mejorar la producción de los paneles fotovoltaicos, captando la máxima radiación de energía solar durante el mayor tiempo posible, a través de sistemas que siguen la trayectoria del sol.As is known, solar trackers will used to improve the production of photovoltaic panels, capturing maximum solar energy radiation during the greatest possible time, through systems that follow the trajectory of the Sun.
Muchas son las firmas que comercializan seguidores solares y muchos los modelos con seguimiento en uno como en dos ejes, dándose en todos ellos una serie de características comunes que pasamos a comentar:Many are the firms that market solar trackers and many models with tracking in one like in two axes, giving in all of them a series of characteristics commons that we comment on:
La agrupación de paneles en el menor espacio posible mediante la formación de estructuras rectangulares y de reducido tamaño.The grouping of panels in the smallest space possible by forming rectangular structures and small size
Esta solución dificulta su integración y agrupación sobre la superficie donde han de ubicarse ya que se necesita emplear un gran número de los mismos, necesitando ocupar más superficie por razones de integración, lo que aumenta los costes finales en infraestructuras y la posibilidad de instalar mayores potencias disminuye su rendimiento, además de desestimar y desaprovechar superficies.This solution makes integration difficult and grouping on the surface where they are to be located since you need to employ a large number of them, needing to occupy more surface for integration reasons, which increases final infrastructure costs and the possibility of installing higher powers decreases its performance, in addition to dismissing and waste surfaces.
Otro de los grandes problemas, es el derivado de su rigidez, ya que la mayoría se anclan a un poste y al no ser giratorias desaprovechan gran parte de la energía que puede generarse.Another major problem is the derivative of its rigidity, since most are anchored to a pole and not being rotating waste of much of the energy that can be generated
Por otra parte, cuando se trata de ejecutar las conocidas como "Huertas solares" mediante la agrupación de seguidores, De los dos ejes de seguimiento solar, orientación acimutal e inclinación, el primero es importante ya que proporciona una ganancia de producción del orden del 30%, mientras que el segundo eje, que controla la inclinación, proporciona una ganancia del orden del 8%.On the other hand, when it comes to running the known as "solar gardens" by grouping followers, two-axis solar tracking, guidance azimuth and inclination, the first is important as it provides a production gain of the order of 30%, while the second axis, which controls the inclination, provides a gain of the order of 8%.
Además, el eje de seguimiento acimutal, es fácilmente ejecutable ya que es una función exclusivamente horaria y por tanto uniforme a lo largo del año, el segundo eje, el de inclinación, varía según la elíptica del sol, su seguimiento con los seguidores convencionales es más complejo y de hecho la mayoría de los grandes seguidores instalados hasta la fecha se limitan al seguimiento de un eje.In addition, the azimuth tracking axis is easily executable since it is an exclusively time function and therefore uniform throughout the year, the second axis, that of inclination, varies according to the elliptical of the sun, its follow-up with conventional followers is more complex and in fact most of the large followers installed to date are limited to axis tracking.
El avance en este campo pasa por la concepción de seguidores mas grandes, robustos y fiables, pensados para una vida útil no inferior a 25 años, que sean menos sensibles al viento y proporciones a los captadores solares, cualquiera que sea su tipo, y en consecuencia a los inversores las mejores condiciones de durabilidad y rendimiento, reduciendo a su vez los costes específicos.The advance in this field goes through conception of larger, more robust and reliable followers, designed for a life span of not less than 25 years, which is less sensitive to wind and proportions to solar collectors, whatever their type, and consequently to investors the best conditions of durability and performance, while reducing costs specific.
Con la presente invención se ha ideado, por tanto, un seguidor solar que tiene por objeto solventar los inconvenientes anteriormente señalados, diseñado con las mejores condiciones de instalación de forma que proporciona a los componentes solares, la máxima efectividad y producción durante su vida útil.With the present invention it has been devised, by therefore, a solar tracker that aims to solve the drawbacks noted above, designed with the best installation conditions in a way that provides solar components, maximum effectiveness and production during useful life.
El sistema en cuestión es un seguidor solar circular de dos ejes, para pequeñas y grandes instalaciones entre 5kWp y 2MWp ó entre 50 m^{2} y 25.000 m^{2}, con diferentes diámetros para ser adaptados a las características de la superficie de que se dispone, y aprovecharla al máximo consiguiendo instalar mayor potencia.The system in question is a solar tracker circular two-axis, for small and large installations between 5kWp and 2MWp or between 50m2 and 25,000m2, with different diameters to be adapted to the surface characteristics available, and make the most of it by installing more power

Capaz de albergar sobre su estructura cualquier sistema de captación solar, y dotándolo de mecanismo de abatimiento. Los captadores se montan sobre una estructura en filas paralelas, con separación suficiente para evitar la incidencia de sombras y pivotados desde el su parte inferior para su inclinación según la época del año (verano o invierno, latitud, etc). Los dos modos de orientación se realizan con servomotores con reductores accionados con automatismo provisto de las coordenadas solares, turbinas hidráulicas u otro sistema opcional.Able to house any structure on its structure solar collection system, and providing it with a mechanism dejection. The sensors are mounted on a row structure parallel, with sufficient separation to avoid the incidence of shadows and pivoted from the bottom for inclination according to the time of the year (summer or winter, latitude, etc). Both Orientation modes are performed with servomotors with reducers automatically operated with solar coordinates, hydraulic turbines or other optional system.
Dicha estructura gira apoyada sobre un eje pivotante o central, hacia uno u otro lado, dependiendo de la orientación solar de cada momento, y guiada a través de bandas de rodadura e impulsada por postes o trenes de avance, mediante servomotores con reductor cuando sea terrestre, lo que en su estructura flotante, se sustituirá por turbinas hidráulicas o motores. A su vez los seguidores circulares de mayor tamaño, tendrán los suficientes apoyos laterales, con la altura que se establezca como más adecuada, para evitar su cabeceo y mejorar su fijación al terreno, además de impulsar su giro.Said structure rotates on an axis pivoting or central, to one side or the other, depending on the solar orientation of each moment, and guided through bands of rolling and driven by poles or feed trains, by servomotors with reducer when it is terrestrial, which in its floating structure, it will be replaced by hydraulic turbines or engines In turn the larger circular followers, they will have enough lateral supports, with the height that set as more appropriate, to avoid pitching and improve your fixing to the ground, in addition to driving its turn.
De esta forma el terreno o superficie donde se instale el seguidor circular es ampliamente aprovechable, ya que se adapta mejor sus irregularidades, pudiendo colocar mayor número de ellos y consiguiendo su completa nivelación, a la vez que su estética es mejor que los convencionales. En un terreno de, por ejemplo, una hectárea donde se podían instalar 100kWp de potencia en paneles fotovoltaicos para producción de energía, con seguidores de dos ejes convencionales, ahora con el seguidor circular se puede instalar 1MWp, realizando el seguimiento solar tanto en orientación como en inclinación, con lo que es posible producir 10 veces más de energía en el mismo espacio.In this way the land or surface where install the circular tracker is widely usable, since it adapts its irregularities better, being able to place more them and getting their full leveling, while their Aesthetic is better than conventional. In a field of, by example, one hectare where 100kWp of power could be installed in photovoltaic panels for energy production, with followers of two conventional axes, now with the circular tracker you can install 1MWp, performing solar tracking both in orientation as in inclination, with what is possible to produce 10 times more than Energy in the same space.
La altura a la que se puede elevar el seguidor solar circular se podrá elegir desde ser colocado sobre el suelo o plataforma flotante, o elevado a cualquier altura sustentándolo sobre otras estructuras portantes o flotantes.The height at which the follower can be raised circular solar can be chosen from being placed on the ground or floating platform, or elevated at any height supporting it on other bearing or floating structures.
Dispondrán además, de un sistema de seguridad basado en una estación meteorológica para casos de nieve o viento. El cual bloqueará en cualquier momento, las filas de captadores solares: tumbándolos para rachas de viento y posicionándolos verticalmente para nieve. Esto además, abaratara tanto el coste como el peso global de los seguidores.They will also have a security system based on a weather station for snow or wind. Which will block at any time, the rows of collectors solar: knocking them down for wind gusts and positioning them vertically for snow. This will also lower the cost so much as the global weight of the followers.
Estas peculiaridades hacen posible que, con este diseño, el seguidor solar pueda fabricarse en grandes dimensiones, permitiendo mejorar la estabilidad y robustez de la instalación, dotando a los captadores solares de un mejor rendimiento a la vez que se reducen los costes específicos y de ocupación del terreno.These peculiarities make it possible that, with this design, the solar tracker can be manufactured in large dimensions, allowing to improve the stability and robustness of the installation, providing solar collectors with better performance at the same time that the specific and occupancy costs of the ground.
Por otra parte, el diseño del seguidor solar de la invención cuida especialmente el comportamiento estructural del conjunto y su estabilidad frente a los vientos y acumulación de nieve ya que se trata de construir grandes estructuras capaces de albergar 5kWp y 2MWp de potencia ó entre 50 m^{2} y 25.000 m^{2} de superficie.Moreover, the solar tracker design of the invention takes special care of the structural behavior of the set and its stability against winds and accumulation of snow since it is about building large structures capable of house 5kWp and 2MWp of power or between 50m2 and 25,000 m2 of surface.
El nuevo seguidor solar representa, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, le dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The new solar tracker represents, by consequently, an innovative structure of features structural and constitutive unknown so far for such end, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that It is requested.
