Description

La présente invention concerne le domaine des panneaux photovoltaïques. Plus particulièrement, la présente invention concerne un panneau photovoltaïque comprenant une surface photosensible et un panneau opaque remarquable en ce que ledit panneau opaque est monté coulissant parallèlement à ladite surface photosensible depuis une position initiale vers une position déployée pour laquelle ledit panneau opaque recouvre l'ensemble de ladite surface photosensible. The present invention relates to the field of photovoltaic panels. More particularly, the present invention relates to a photovoltaic panel comprising a photosensitive surface and an opaque panel which is remarkable in that said opaque panel is slidably mounted parallel to said photosensitive surface from an initial position towards a deployed position for which said opaque panel covers the assembly. of said photosensitive surface.

Domaine technique La diminution des ressources en énergie fossile non renouvelable et les problèmes liés au rejet des gaz à effet de serre dans l'atmosphère ont entraîné une augmentation des installations de productions électriques basées sur des ressources renouvelables. Parmi celles-ci, les panneaux solaires photovoltaïques offrent une solution de plus en plus utilisée que ce soit par des particuliers où sur des sites uniquement destinés à la production d'énergie. Chez les particuliers, les panneaux photovoltaïques sont couramment associés à la structure du bâtiment, notamment au toit. L'énergie produite est utilisée principalement sur place et éventuellement redistribuée vers le réseau de distribution. Cette disposition particulière pose de nouveaux problèmes de sécurité. En effet, s'ils représentent un intérêt évident en termes de développement durable, ils causent aussi un risque nouveau pour les personnes amenées à intervenir sur les bâtiments lors d'éventuels incendies. Ces panneaux produisent du courant électrique, tant qu'il y a de la lumière. En cas d'incendie dans un bâtiment équipé, les sapeurs-pompiers doivent prendre garde de ne pas projeter de l'eau vers les EDITE1-FR-1 TEXTE DEPOSE SO/SL 2961023 - 2 - parties sous tension. Cette précaution est malheureusement difficilement applicable lorsque de grandes surfaces sont recouvertes par des panneaux photovoltaïques. Technical Area The decline in non-renewable fossil energy resources and the problems associated with the release of greenhouse gases into the atmosphere have led to an increase in renewable generation-based electricity generation facilities. Among these, photovoltaic solar panels offer a solution increasingly used by individuals or on sites solely for energy production. In individuals, photovoltaic panels are commonly associated with the structure of the building, including the roof. The energy produced is used mainly on site and eventually redistributed to the distribution network. This particular provision raises new security issues. Indeed, while they represent an obvious interest in terms of sustainable development, they also cause a new risk for people who have to intervene on buildings during fires. These panels produce electricity as long as there is light. In the event of a fire in an equipped building, the fire brigade must be careful not to throw water at the live parts. This precaution is unfortunately difficult to apply when large areas are covered by photovoltaic panels.

5 Exposé de l'invention La présente invention propose un nouveau type de panneau photovoltaïque ne présentant pas les inconvénients précédemment décrits. La présente invention concerne un panneau 10 photovoltaïque comprenant une surface photosensible et un panneau opaque remarquable en ce que ledit panneau opaque est monté coulissant parallèlement à ladite surface photosensible depuis une position initiale vers une position déployée pour laquelle ledit panneau opaque 15 recouvre l'ensemble de ladite surface photosensible. Ainsi, lorsque ledit panneau opaque est en position déployée, ladite surface photosensible ne reçoit plus de rayonnement lumineux et le panneau ne produit plus d'énergie et ne présente donc plus aucun risque pour les personnes 20 cherchant à intervenir sur le bâtiment comportant lesdits panneaux. Dans le cadre de la présente invention, le terme « surface photosensible » correspond à la surface comprenant les cellules photovoltaïques éventuellement 25 recouvertes par une surface translucide. Dans le cadre de la présente invention, le terme « panneau opaque » fait référence à un panneau souple ou rigide opaque. Ledit panneau opaque pourra être notamment choisi dans le groupe comprenant les stores en matières 30 plastiques ou en tissus, les volets roulants, les panneaux en bois, en métal ou en matière plastique. Selon un mode de réalisation préféré de l'invention ledit panneau opaque est constitué en tout ou partie par un ou plusieurs matériaux appartenant à la catégorie MO ou Ml de la norme EDITE1-FR-1 TEXTE DEPOSE SO/SL - 3 NF P.92.507. Selon un mode de réalisation tout à fait préféré de l'invention ledit panneau opaque est constitué en totalité par un ou plusieurs matériaux appartenant à la catégorie MO ou M1 de la norme NF P.92.507. SUMMARY OF THE INVENTION The present invention proposes a new type of photovoltaic panel which does not have the disadvantages described above. The present invention relates to a photovoltaic panel 10 comprising a photosensitive surface and an opaque panel characterized in that said opaque panel is slidably mounted parallel to said photosensitive surface from an initial position to an extended position for which said opaque panel 15 covers the entire surface. said photosensitive surface. Thus, when said opaque panel is in the deployed position, said photosensitive surface no longer receives light radiation and the panel no longer produces energy and no longer poses any risk for persons seeking to intervene on the building comprising said panels. In the context of the present invention, the term "photosensitive surface" corresponds to the surface comprising photovoltaic cells optionally covered by a translucent surface. In the context of the present invention, the term "opaque panel" refers to an opaque flexible or rigid panel. Said opaque panel may in particular be chosen from the group comprising blinds made of plastics or fabrics, roller shutters, panels made of wood, metal or plastic. According to a preferred embodiment of the invention said opaque panel is constituted in whole or in part by one or more materials belonging to the category MO or Ml of the standard EDITE1-FR-1 TEXTE REMOVAL SO / SL - 3 NF P.92.507 . According to a most preferred embodiment of the invention, said opaque panel is constituted in its entirety by one or more materials belonging to category MO or M1 of standard NF P.92.507.

Le déplacement dudit panneau opaque vis de ladite surface photosensible peut être indifféremment motorisé, entrainé par la force humaine ou induit par la gravité. Selon un mode de réalisation préféré de l'invention ledit panneau opaque est un volet roulant. The displacement of said opaque panel vis-a-vis said photosensitive surface can be indifferently motorized, driven by human force or induced by gravity. According to a preferred embodiment of the invention said opaque panel is a shutter.

Ladite surface photosensible et ledit panneau opaque peuvent être solidaires ou indépendants. Avantageusement ledit panneau opaque peut être dissocié de ladite surface photovoltaïque. Ainsi, les deux éléments peuvent être entretenus et remplacés séparément. Said photosensitive surface and said opaque panel may be integral or independent. Advantageously, said opaque panel can be dissociated from said photovoltaic surface. Thus, both elements can be maintained and replaced separately.

Description sommaire des dessins La figure 1 présente une vue de coupe d'un mode de réalisation d'un panneau selon l'invention. Brief Description of the Drawings Figure 1 shows a sectional view of an embodiment of a panel according to the invention.

La figure 2 présente une vue de dessus d'un mode de réalisation d'un panneau selon l'invention. Figure 2 shows a top view of an embodiment of a panel according to the invention.

Description des modes de réalisation En référence à la figure 1, le panneau photovoltaïque 1 comprend une surface photosensible 2 qui peut être choisie parmi tous les types de panneaux solaires existant sur le marché. Ce panneau photovoltaïque 1 comprend avantageusement deux rails 4 placés de part et d'autre de ladite surface 2 apte à recevoir les bords longitudinaux du panneau opaque 3 qui va ainsi pouvoir coulisser parallèlement à la surface photosensible 2. La figure 1 et la figure 2 représentent un panneau 1 selon l'invention dans laquelle le panneau opaque 3 est dans une position intermédiaire entre la position initiale, [DITE1-FR-1 TEXTE DEPOSE_SO/SL 2961023 - 4 - où tout le panneau opaque 3 est dans le boîtier 5, et la position déployée où toute la surface 2 est recouverte par le panneau opaque 3. Avantageusement, le panneau photovoltaïque 1 5 comprendra en outre un boîtier 5 apte à recevoir ledit panneau opaque 3 lorsque celui-ci est en position initiale. DESCRIPTION OF THE EMBODIMENTS With reference to FIG. 1, the photovoltaic panel 1 comprises a photosensitive surface 2 that can be chosen from all types of solar panels existing on the market. This photovoltaic panel 1 advantageously comprises two rails 4 placed on either side of said surface 2 adapted to receive the longitudinal edges of the opaque panel 3 which will thus be able to slide parallel to the photosensitive surface 2. FIG. 1 and FIG. a panel 1 according to the invention in which the opaque panel 3 is in an intermediate position between the initial position, [DITE1-FR-1 TEXTE DEPOSE_SO / SL 2961023 - 4 - where all the opaque panel 3 is in the housing 5, and the deployed position where the entire surface 2 is covered by the opaque panel 3. Advantageously, the photovoltaic panel 1 5 will further include a housing 5 adapted to receive said opaque panel 3 when it is in the initial position.

Lorsque ledit panneau opaque 3 est un volet roulant, le panneau photovoltaïque 1 peut avantageusement comprendre 10 un arbre autour duquel ledit panneau opaque 3 peut être enroulé. Selon un autre mode de réalisation préféré le panneau photovoltaïque selon l'invention comprendra en outre un moyen apte à mettre en mouvement le panneau opaque 3 pour 15 le faire passer de la position initiale à la position déployée et vice versa. Selon un mode de réalisation encore plus préféré le panneau photovoltaïque selon l'invention, comprendra en outre un moteur 6 apte à mettre en mouvement le panneau opaque 3 pour le faire passer de la position 20 initiale à la position déployée et vice versa. Selon un mode de réalisation tout à fait préféré ledit moteur 6 relié audit arbre autour duquel ledit panneau opaque 3 peut être enroulé. Selon un autre mode de réalisation encore plus préféré ledit moyen apte à mettre en mouvement le 25 panneau opaque 3 pour le faire passer de la position initiale à la position déployée et vice versa est une manivelle reliée audit arbre autour duquel ledit panneau opaque 3 peut être enroulé. When said opaque panel 3 is a shutter, the photovoltaic panel 1 may advantageously comprise a shaft around which said opaque panel 3 can be wound. According to another preferred embodiment, the photovoltaic panel according to the invention will also comprise means capable of moving the opaque panel 3 to move it from the initial position to the deployed position and vice versa. According to an even more preferred embodiment the photovoltaic panel according to the invention, will further include a motor 6 adapted to move the opaque panel 3 to move it from the initial position 20 to the deployed position and vice versa. According to a most preferred embodiment, said motor 6 connected to said shaft around which said opaque panel 3 can be wound. According to another even more preferred embodiment, said means capable of moving the opaque panel 3 to move it from the initial position to the deployed position and vice versa is a crank connected to said shaft around which said opaque panel 3 may be wound.

30 Ledit moteur 6 sera avantageusement alimenté par une batterie, permettant ainsi le déplacement du panneau opaque 3 en l'absence d'alimentation électrique provenant du réseau public de distribution. Par ailleurs, le déplacement de la position initiale EDITE1-FR-1 TEXTE DEPOSE SO/SL - 5 vers la position déployée est avantageusement déclenché par un moyen de détection d'un incendie tel qu'un détecteur de fumée ou un thermomètre. Ainsi une élévation de température et/ou l'apparition de fumée entraine automatiquement la mise sous tension du moteur 6 et le déplacement du panneau opaque 3 qui va couvrir l'ensemble de la surface photosensible 2. L'occultation de la surface photosensible 2 conduit à l'arrêt de la production électrique par le panneau photovoltaïque 1. Il devient donc possible d'intervenir en toute sécurité sur l'habitation supportant le panneau photovoltaïque selon l'invention. Par ailleurs, le déplacement du panneau opaque 3 peut avantageusement être déclenché en dehors des conditions d'incendie afin de vérifier le bon fonctionnement du système. EDITE1-FR-1 TEXTE DEPOSESO/SL Said motor 6 will advantageously be powered by a battery, thereby allowing the opaque panel 3 to move in the absence of an electrical supply coming from the public distribution network. Furthermore, the displacement of the initial position EDITE1-FR-1 TEXTE REMOVAL SO / SL - 5 to the deployed position is advantageously triggered by a fire detection means such as a smoke detector or a thermometer. Thus, a rise in temperature and / or the appearance of smoke automatically causes the motor 6 to be energized and the opaque panel 3 to move, which will cover the entire photosensitive surface 2. The occultation of the photosensitive surface 2 leads to when the electricity production is stopped by the photovoltaic panel 1. It thus becomes possible to intervene in complete safety on the dwelling supporting the photovoltaic panel according to the invention. Furthermore, the displacement of the opaque panel 3 may advantageously be triggered outside the fire conditions to verify the proper operation of the system. EDITE1-FR-1 TEXT DEPOSESO / SL
