DESCRIPCIÓN DESCRIPTION
Título : SOPORTE PARA LAMINADOS FOTOVOLTAICOS Sector de Ia técnica : Edificación y sistemas fotovoltaicos Objeto de Ia invenciónTitle: SUPPORT FOR PHOTOVOLTAIC LAMINATES Sector of the technique: Building and photovoltaic systems Object of the invention
La invención se refiere a un soporte que permite instalar laminados fotovoltaicos en los edificios. Antecedentes de Ia invenciónThe invention relates to a support that allows to install photovoltaic laminates in buildings. Background of the invention
El aprovechamiento del efecto fotovoltaico para generar energía eléctrica se ha hecho habitualmente en campo abierto, donde se puede disponer de grandes superficies expuestas a Ia radiación solar.The use of the photovoltaic effect to generate electrical energy has usually been done in the open field, where large surfaces exposed to solar radiation can be disposed.
Sin embargo, dicho aprovechamiento se ha ido extendiendo a los edificios debido a que también éstos cuentan con grandes superficies expuestas a Ia radiación solar, a que Ia energía eléctrica se genera cerca del lugar de consumo, y a que no se ocupa suelo nuevo adicional exclusivamente para ese uso.However, this use has been extended to buildings because they also have large surfaces exposed to solar radiation, to which the electric power is generated near the place of consumption, since no additional new floor is used exclusively for that use.
Los antecedentes del soporte para laminados fotovoltaicos objeto de Ia presente solicitud de Modelo de Utilidad se encuentran en esta implantación del aprovechamiento fotovoltaico en los edificios, consistente en Ia colocación de elementos fotovoltaicos en sus fachadas o cubiertas expuestas al sol.The background of the support for photovoltaic laminates object of the present utility model application is found in this implementation of photovoltaic use in buildings, consisting of the placement of photovoltaic elements on their facades or roofs exposed to the sun.
Esa colocación tiene dos posibles variantes en el estado de Ia técnica:This placement has two possible variants in the state of the art:
- disposición de los elementos fotovoltaicos fijados comúnmente a una estructura auxiliar que a su vez está fijada al edificio, es decir, se trata de una superposición de los elementos fotovoltaicos al edificio.- provision of the photovoltaic elements commonly fixed to an auxiliary structure which in turn is fixed to the building, that is, it is a superposition of the photovoltaic elements to the building.
- disposición de los elementos fotovoltaicos sustituyendo elementos constructivos de Ia fachada o Ia cubierta del edificio, denominándose esta disposición integración fotovoltaica.- disposition of the photovoltaic elements replacing constructive elements of the facade or the roof of the building, this arrangement being called photovoltaic integration.
Ambos caminos condicionan Ia modalidad técnica que presentan los elementos fotovoltaicos que en ellos se utilizan.Both roads determine the technical modality of the photovoltaic elements that are used in them.
En el caso de superposición se utilizan los llamados módulos fotovoltaicos, en los que los elementos fotovoltaicos activos o células fotovoltaicas se encuentran asociados eléctrica y físicamente conformando un laminado fotovoltaico que es un elemento multicapa compuesto además por vidrio y otras láminas de materiales sintéticos, estando a su vez este laminado fotovoltaico montado en un marco o bastidor metálico que Ie confiere rigidez mecánica para su uso. Es decir, en el caso de superposición se utilizan módulos fotovoltaicos, que están compuestos por el laminado fotovoltaico montado en un bastidor, realizándose Ia fijación a Ia estructura auxiliar mediante dicho bastidor, que es el que aporta las prestaciones mecánicas. Se contemplan soluciones de este tipo, por ejemplo, en el documento W9706264US CONJUNTO FOTOVOLTAICO PARA RECUBRIMIENTO DE TEJADOS, AUTOLASTRADO Y LIGERO, en el documento E99305599 SISTEMA DE ENTRAMADO DE MÓDULOS FOTOVOLTAICOS CON CANALIZACIONES ELÉCTRICAS INTEGRALES y en el documento U200801305 SOPORTE PARA PLACAS FOTOVOLTAICAS, que expone una solución en Ia que ya no se utiliza estructura auxiliar. En este caso de superposición pues, el soporte de los elementos activos fotovoltaicos sería el laminado fotovoltaico y, en última instancia, el bastidor metálico.In the case of superposition, so-called photovoltaic modules are used, in which the active photovoltaic elements or photovoltaic cells are associated electrically and physically forming a photovoltaic laminate which is a multilayer element also composed of glass and other sheets of synthetic materials, being a in turn this photovoltaic laminate mounted on a metal frame or frame that gives it mechanical rigidity for its use. That is, in the case of superposition, photovoltaic modules are used, which are composed of the photovoltaic laminate mounted on a frame, the fixing to the auxiliary structure being carried out by means of said frame, which is the one that provides the mechanical benefits. He contemplate solutions of this type, for example, in document W9706264US PHOTOVOLTAIC ASSEMBLY FOR ROOF COATING, AUTOLASTRADO AND LIGHT, in document E99305599 SYSTEM OF ENTRAMADO OF PHOTOVOLTAIC MODULES WITH INTEGRAL ELECTRIC CHANNELS and in the document U200801305 SUPPORT FOR PHOTOVOLTAIC PLATES, which exposes a solution in which auxiliary structure is no longer used. In this case of superposition, then, the support of the photovoltaic active elements would be the photovoltaic laminate and, ultimately, the metal frame.
En el caso de Ia integración fotovoltaica, los elementos fotovoltaicos activos se disponen en el propio elemento constructivo con el objetivo de que formen parte del edificio como elemento constructivo y ahorrar de esta manera tanto los bastidores como Ia estructura auxiliar. En el estado de Ia técnica actual existen ya numerosos elementos constructivos constituyentes de las fachadas o cubiertas de los edificios con esta singularidad. Citaremos entre ellos el documento P9901929 REVESTIMIENTO GENERADOR DE ENERGÍA FOTOVOLTAICA, el documento U200700053 PANEL FOTOVOLTAICO PARA CUBIERTAS Y SIMILARES, el documento W06000247ES TEJA SOLAR FOTOVOLTAICA, el documento E05075682 CONJUNTO DE TEJA SOLAR, el documento U200801801 TEJA SOLAR, el documento W04013409EP PANEL DE VIDRIO AISLANTE FOTOVOLTAICO, el documento W0210620EP ACRISTALAMIENTO AISLANTE FOTOVOLTAICO, y el documento E05105204 MODULO SOLAR COMO UN VIDRIO LAMINADO DE SEGURIDAD, que se refieren a diversos elementos constructivos que contienen elementos fotovoltaicos, tales como piezas de revestimiento cerámico sobre las que se han laminado células fotovoltaicas, piezas de cubiertas sobre las que se han laminado elementos fotovoltaicos, tejas o piezas de tejado que llevan insertadas células fotovoltaicas, y acristalamientos de edificios que incorporan células fotovoltaicas laminadas en sus vidrios. En este caso de integración pues, el soporte de los elementos activos fotovoltaicos es directamente el propio elemento constructivo, sin que medie entre ellos el laminado fotovoltaico tal como se ha definido.In the case of the photovoltaic integration, the active photovoltaic elements are arranged in the constructive element itself with the aim that they form part of the building as a constructive element and thus save both the frames and the auxiliary structure. In the current state of the art there are already numerous constructive elements constituting the facades or roofs of buildings with this singularity. We will cite among them the document P9901929 COATING PHOTOVOLTAIC ENERGY GENERATOR, the document U200700053 PHOTOVOLTAIC PANEL FOR COVERINGS AND SIMILARS, the document W06000247ES TEOT SOLAR PHOTOVOLTAIC, the document E05075682 SET OF THE SOLAR ROOF, the document U200801801 TEJA SOLAR, the document W04013409EP INSULATING GLASS PANEL PHOTOVOLTAIC, document W0210620EP PHOTOVOLTAIC INSULATING GLAZING, and document E05105204 SOLAR MODULE AS A LAMINATED SAFETY GLASS, which refer to various construction elements that contain photovoltaic elements, such as pieces of ceramic coating on which photovoltaic cells have been laminated, pieces of roofs on which photovoltaic elements have been laminated, tiles or pieces of roof that have inserted photovoltaic cells, and glazing of buildings that incorporate photovoltaic cells laminated in their glasses. In this case of integration, then, the support of the photovoltaic active elements is directly the constructive element itself, without there being between them the photovoltaic laminate as it has been defined.
Tanto un caso como otro constituyen los antecedentes del soporte para laminados fotovoltaicos objeto de este Modelo de Utilidad que aporta ventajas sobre los soportes anteriores citados, tal como se expondrá y argumentará en Ia descripción de Ia invención. Descripción de Ia invención El problema técnico que resuelve Ia invención es posibilitar el aprovechamiento fotovoltaico en los edificios mediante Ia disposición en sus fachadas o cubiertas de elementos fotovoltaicos solucionándolo de modo nuevo y distinto en relación al estado de Ia técnica actual, aportando las ventajas que se citarán.Both a case and another constitute the background of the support for photovoltaic laminates object of this Utility Model that provides advantages over the aforementioned previous supports, as will be explained and argued in the description of the invention. Description of the invention The technical problem solved by the invention is to enable photovoltaic use in buildings by providing their facades or roofs with photovoltaic elements, solving them in a new and different way in relation to the current state of the art, providing the advantages that will be cited.
El soporte para laminados fotovoltaicos objeto del presente Modelo de Utilidad está formado por Ia propia pieza de revestimiento de fachada o cubierta del edificio pero dotada de resaltes adicionales, situados en su cara exterior, específicos para el encastre y montaje en ellos del laminado fotovoltaico. Dichos resaltes tienen forma de U, L, T o similares y se disponen, en una realización preferente de Ia invención, paralelas a los bordes largos de Ia pieza y cercanos a ellos. En los dibujos que forman parte de este Modelo de Utilidad y que se describirán más adelante se ilustra dicha configuración.The support for photovoltaic laminates object of the present Utility Model is formed by the own piece of facade cladding or roof of the building but equipped with additional projections, located on its outer face, specific for the fitting and mounting in them of the photovoltaic laminate. Said projections have the shape of U, L, T or similar and are arranged, in a preferred embodiment of the invention, parallel to the long edges of the piece and close to them. In the drawings that are part of this Utility Model and that will be described later, said configuration is illustrated.
Dicho soporte, por tanto, es diferente de los existentes actualmente en el estado de Ia técnica y mencionados en el anterior apartado de antecedentes.Said support, therefore, is different from those currently existing in the state of the art and mentioned in the previous section of the background.
En efecto, en relación al primer caso, o de superposición, se siguen utilizando los laminados fotovoltaicos, pero su soporte no serán los bastidores ni Ia estructura auxiliar, sino un elemento constructivo ya presente en el edificio, en particular, sus piezas de revestimiento dotadas de resaltes ad hoc.In fact, in relation to the first case, or superposition, the photovoltaic laminates are still used, but their support will not be the frames or the auxiliary structure, but a constructive element already present in the building, in particular, its coated parts of ad hoc highlights.
En relación al segundo caso o de integración Ia diferencia también es notable pues ahora el soporte de los elementos activos fotovoltaicos no es el elemento constructivo directamente, sino el laminado fotovoltaico, siendo este hecho muy importante y rasgo diferenciador definitorio.In relation to the second case or integration, the difference is also notable because now the support of the photovoltaic active elements is not the constructive element directly, but the photovoltaic laminate, this fact being very important and distinguishing feature defining.
Las ventajas y aspectos diferenciales respecto al estado de Ia técnica actual son evidentes pues este soporte resuelve Ia mayor parte de los problemas e inconvenientes de los soportes citados y aporta nuevas ventajas.The advantages and differential aspects with respect to the current state of the art are evident since this support solves most of the problems and disadvantages of the cited supports and brings new advantages.
Para el caso de superposición resuelve el problema técnico de Ia estructura soporte auxiliar al no ser necesaria y aporta Ia ventaja del ahorro tanto de dicha estructura como de los bastidores de los módulos fotovoltaicos.In the case of superposition, it solves the technical problem of the auxiliary support structure since it is not necessary and provides the advantage of saving both said structure and the frames of the photovoltaic modules.
Para el caso de integración, los problemas de esa modalidad de soporte provienen del hecho de que, al ser simultáneamente elemento constructivo y soporte de los elementos activos fotovoltaicos, debe cumplir todos los requerimientos técnicos propios de ambos. Así, como elemento constructivo debe aportar impermeabilidad, aislamiento térmico, aislamiento acústico, etc, según los casos, debiendo, por otra parte y a Ia vez, atender a las demandas técnicas de los elementos activos fotovoltaicos. Señalaremos entre éstas dos muy importantes: Ia existencia ineludible de cableado y Ia aconsejable ventilación de las células fotovoltaicas en aras de un adecuado rendimiento eléctrico. Por ello, se genera un conflicto y diversos inconvenientes y atributos negativos, siendo los más relevantes Ia complejidad de ejecución, Ia complejidad de mantenimiento y reposición, y el poco rendimiento eléctrico, existiendo todos ellos en las soluciones actuales citadas.In the case of integration, the problems of this type of support come from the fact that, being simultaneously constructive element and support of the active photovoltaic elements, it must meet all the technical requirements of both. Thus, as a constructive element it must provide impermeability, thermal insulation, acoustic insulation, etc., depending on the case, and must, on the other hand, and at the same time, meet the technical demands of the active photovoltaic elements. We will point out two very important ones: the unavoidable existence of wiring and the advisable ventilation of the photovoltaic cells for the sake of adequate electrical performance. Therefore, a conflict and various negative attributes and attributes are generated, the most relevant being the complexity of execution, the complexity of maintenance and replacement, and the low electrical performance, all existing in the current solutions cited.
El soporte para laminados fotovoltaicos que se especifica tiene en cuenta que los elementos fotovoltaicos son elementos activos con leyes propias y da respuesta a los inconvenientes citados al constituirse en un soporte exclusivamente mecánico, en el que se inserta de manera diferenciada el elemento fotovoltaico en forma de laminado fotovoltaico. Ello comporta las siguientes grandes ventajas diferenciales respecto al estado de Ia técnica: ventilación de los elementos fotovoltaicos y por tanto mayor rendimiento eléctrico; simplicidad, versatilidad e independencia del cableado y su trazado; facilidad de mantenimiento y de cambio y reposición de los elementos fotovoltaicos sin comprometer ninguna prestación técnica del revestimiento del edificio; posibilidad de implantación de los elementos fotovoltaicos simultáneamente a Ia ejecución del edificio o en etapas posteriores; posibilidad de uso en rehabilitación de edificios. Y todo ello sin necesidad de estructura auxiliar ni de bastidores para los laminados.The support for photovoltaic laminates that is specified takes into account that the photovoltaic elements are active elements with their own laws and responds to the aforementioned drawbacks by constituting an exclusively mechanical support, in which the photovoltaic element is inserted in a differentiated manner in the form of photovoltaic laminate. This entails the following major differential advantages with respect to the state of the art: ventilation of the photovoltaic elements and therefore greater electrical efficiency; simplicity, versatility and independence of the wiring and its layout; ease of maintenance and change and replacement of the photovoltaic elements without compromising any technical performance of the building envelope; possibility of implementation of the photovoltaic elements simultaneously to the execution of the building or in later stages; possibility of use in building rehabilitation. And all this without the need for an auxiliary structure or frames for the laminates.
Señalar finalmente que el soporte para laminados fotovoltaicos tiene un modo particular de realización de Ia invención consistente en que son las grapas de fijación del revestimiento del edificio las que se dotan de recrecidos, ampliaciones o complementos adicionales específicos para el montaje de los laminados fotovoltaicos.Finally point out that the support for photovoltaic laminates has a particular mode of realization of the invention consisting of the fixing clamps of the building lining which are provided with screeds, extensions or additional specific accessories for the assembly of the photovoltaic laminates.
Asimismo otro modo particular de realización de Ia invención, para el caso de las zonas acristaladas, consistente en que las tapetas de fijación de los acristalamientos del edificio están dotadas de recrecidos, ampliaciones o complementos adicionales específicos para el montaje de los laminados fotovoltaicos.Also another particular embodiment of the invention, in the case of glazed areas, consisting in that the fixing caps of the building glazings are equipped with screeds, extensions or additional specific accessories for the assembly of the photovoltaic laminates.
Para estos modos de realización de Ia invención siguen siendo válidas todas las ventajas citadas.For all these embodiments of the invention, all the advantages mentioned are still valid.
Añadir además, como característica específica que aporta Ia invención, el hecho de que permite dotar a los edificios de un sistema activo de generación de energía manteniendo en su fachada o cubierta sus soluciones técnicas y estéticas iniciales al utilizarse los mismos materiales y los mismos sistemas constructivos, facilitando que su uso se pueda realizar parcialmente, en determinadas zonas de fachadas o cubiertas, las que están soleadas, sin introducción de nuevas técnicas y sin menoscabo de los aspectos estéticos y compositivos del edificio. Descripción de los dibujos Al objeto de complementar Ia descripción que se está realizando y de facilitar Ia comprensión de Ia invención y de las reivindicaciones, se acompaña a Ia presente memoria descriptiva un conjunto de dibujos en los que, con carácter ilustrativo y no limitativo, se representan un modo particular de realización de Ia invención.Also add, as a specific feature provided by the invention, the fact that it provides the buildings with an active energy generation system by maintaining their initial technical and aesthetic solutions in their façade or roof when the same materials and construction systems are used. , facilitating that its use can be carried out partially, in certain areas of facades or roofs, which are sunny, without introduction of new techniques and without detriment to the aesthetic and compositional aspects of the building. Description of the drawings In order to complement the description that is being made and to facilitate the understanding of the invention and the claims, the present descriptive report is accompanied by a set of drawings in which, in an illustrative and non-limiting manner, a particular embodiment of the invention is represented.
Figura 1 : muestra el soporte para laminados fotovoltaicos en el modo particular de realización de Ia invención en el que el revestimiento del edificio en su cubierta está resuelto con las piezas denominadas paneles sandwich por estar constituidas por un alma de material aislante situada entre dos láminas metálicas perfiladas. Se grafía su sección (1) en Ia que se señalan sus resaltes adicionales(ia) configurados con el perfilado de Ia lámina superior, específicos para el encastre y montaje de los laminados fotovoltaicos.

Estos resaltes adicionales se disponen a una distancia entre ellos apropiada a las dimensiones del laminado fotovoltaico que se vaya a instalar. En una variante de realización de Ia invención, los resaltes adicionales podrían ser sustituidos por Ia modificación de las propias nervaduras laterales de Ia pieza de modo que pudiese realizarse sobre ellas el asiento y montaje de los laminados, requiriendo ello un acuerdo dimensional entre Ia anchura del panel sandwich, así constituido como soporte para laminados fotovoltaicos, y el laminado fotovoltaico que se fuese a instalar sobre él.As seen in figures 1 and 2, in one embodiment of the invention, the support for photovoltaic laminates (1) is constituted by one of the building cladding pieces, in this case of the cover solved with sandwich panels, equipped of additional projections on its outer face (1a) specific for the assembly of photovoltaic laminates. The sandwich panels (2) are constituted by a core of insulating material located between two profiled metal sheets. Its upper metallic foil, to configure the support of the photovoltaic laminates, is profiled so that additional projections are introduced, parallel to their longitudinal edges, substantially similar to the ribs of the standard panel itself, also filled by the insulating material, that in their outermost zone they present an L-shaped seat recess in which the photovoltaic laminate is embedded and mounted. These additional projections are arranged at a distance between them appropriate to the dimensions of the photovoltaic laminate to be installed. In a variant embodiment of the invention, the additional projections could be replaced by the modification of the lateral ribs of the piece itself so that the seat and assembly of the laminates could be made on them, this requires a dimensional agreement between the width of the sandwich panel, thus constituted as support for photovoltaic laminates, and the photovoltaic laminate that was to be installed on it.
Como se observa en las figuras, entre el soporte para laminados fotovoltaicos y el laminado fotovoltaico existe una cámara de aire abierta que proporciona Ia ventilación trasera de los módulos, conveniente para un óptimo rendimiento eléctrico, y permite el adecuado, independiente y registrable trazado del cableado, tal como se ha comentado en Ia descripción.As seen in the figures, between the support for photovoltaic laminates and the photovoltaic laminate there is an open air chamber that provides the rear ventilation of the modules, convenient for an optimal electrical performance, and allows the adequate, independent and recordable routing of the wiring , as mentioned in the description.
Una vez descrita suficientemente Ia naturaleza de Ia invención se hace constar, a los efectos oportunos, que los materiales, forma, tamaño y disposición de las partes del soporte para laminados fotovoltaicos podrán ser distintos siempre que ello no suponga una alteración de las características esenciales de Ia invención que se reivindican en su apartado correspondiente. Posibilidades de aplicación industrialOnce sufficiently described the nature of the invention it is stated, for the appropriate purposes, that the materials, shape, size and arrangement of the parts of the support for photovoltaic laminates may be different provided that this does not entail an alteration of the essential characteristics of the photovoltaic laminate.
