Description

La présente invention se rapporte à une installation solaire pour toiture-terrasse, à une toiture solaire comportant une telle installation solaire ainsi qu'à un procédé de montage d'une telle installation solaire sur une toiture-terrasse. The present invention relates to a solar installation for roof terrace, to a solar roof comprising such a solar installation and to a method of mounting such a solar installation on a roof terrace.

L e montage d e panneaux solaires, notamment du type photovoltaïque, sur une toiture-terrasse peut conduire à la formation d'étendues d'eaux stagnantes, en particulier sous les panneaux solaires, ces eaux stagnantes ne pouvant s'évaporer naturellement avec le soleil et/ou le vent. Or, la macération de déchets et/ou de larves dans de telles étendues d'eaux stagnantes peut conduire à nuisances olfactives et/ou la prolifération d'insectes. Il est notamment connu de l'état de la technique d'utiliser des modules solaires souples, du type photovoltaïque, intégrés à des membranes d'étanchéité, ces membranes étant généralement réalisées en matière plastique. Ces modules solaires souples recouvrent ainsi de manière étanche la toiture-terrasse et évitent la formation d'eaux stagnantes. Cependant, lors d'intempéries, les eaux de pluie s'accumulent à la surface de tels modules solaires souples avant que les eaux de pluie ne puissent s'évaporer naturellement avec le soleil et/ou le vent. Une telle accumulation d'eaux de pluie peut être préjudiciable pour le fonctionnement de tels modules solaires souples. La présente invention vise à remédier à l'inconvénient précité et concerne une installation solaire pour toiture-terrasse, caractérisée en ce qu'elle comporte : - au moins une couche de recouvrement isolante destinée à recouvrir la toiture-terrasse, - une pluralité de conduits ouverts sensiblement parallèles entre eux disposée sur la couche de recouvrement, chaque conduit s'étendant suivant un axe longitudinal et comprenant deux parois latérales reliées entre elles par un fond, - une pluralité de panneaux solaires, de préférence du type photovoltaïque, chacun étant monté sur les deux parois latérales se faisant face de deux conduits adjacents, les panneaux solaires étant reliés longitudinalement entre eux de manière étanche. The installation of solar panels, especially of the photovoltaic type, on a roof terrace can lead to the formation of stagnant water areas, especially under the solar panels, these stagnant waters not being able to evaporate naturally with the sun and / or the wind. However, the maceration of waste and / or larvae in such stagnant water areas can lead to odor nuisance and / or the proliferation of insects. It is in particular known from the state of the art to use flexible solar modules, of the photovoltaic type, integrated in waterproofing membranes, these membranes being generally made of plastics material. These flexible solar modules thus cover the roof terrace and prevent the formation of stagnant water. However, during inclement weather, rainwater accumulates on the surface of such flexible solar modules before rainwater can naturally evaporate with the sun and / or the wind. Such accumulation of rainwater can be detrimental to the operation of such flexible solar modules. The present invention aims to remedy the aforementioned drawback and relates to a solar installation for roof terrace, characterized in that it comprises: - at least one insulating covering layer intended to cover the roof terrace, - a plurality of conduits substantially parallel to each other disposed on the covering layer, each duct extending along a longitudinal axis and comprising two side walls interconnected by a bottom, - a plurality of solar panels, preferably photovoltaic type, each mounted on the two side walls facing two adjacent ducts, the solar panels being longitudinally connected to each other in a sealed manner.

Ainsi, la présence de tels conduits ouverts permet d'évacuer les eaux de pluie et de s'affranchir par là-même d'accumulations d'eaux de pluie sur les panneaux solaires, notamment lors d'intempéries. Par ailleurs, de tels conduits peuvent être conformés pour délimiter 5 des zones de circulation pour des opérateurs afin de faciliter le montage et la maintenance des panneaux solaires par ces opérateurs. En outre, le fait que les panneaux solaires soient reliés longitudinalement entre eux de manière étanche, en conjugaison avec la présence de la couche de recouvrement isolante, permet d'éviter la formation 10 d'étendues d'eaux stagnantes, en particulier sous les panneaux solaires. Dans un mode de réalisation, les deux parois latérales de chaque conduit présentent chacune à leur extrémité libre un rebord longitudinal sur lequel est montée la pluralité de panneaux solaires. Ainsi, de tels rebords longitudinaux confèrent une surface d'appui 15 et une stabilité accrus des panneaux solaires sur les parois latérales. Avantageusement, les deux parois latérales se faisant face des conduits adjacents présentent des dimensions transversales conçues de sorte que la pluralité de panneaux solaires s'étend suivant une direction oblique. Ainsi, l'inclinaison des panneaux solaires obtenue permet 20 d'améliorer par gravité la circulation des eaux de pluie de la surface des panneaux solaires vers les conduits. Selon une forme d'exécution, chaque conduit comprend deux parois latérales s'étendant sensiblement suivant un axe vertical de manière à former une section transversale sensiblement en forme de U. 25 Selon une réalisation particulière, les panneaux solaires sont reliés longitudinalement entre eux par des traverses étanches. Avantageusement, la couche de recouvrement isolante est réalisée dans un matériau isolant thermique, de préférence du type polystyrène rigide. Ainsi, une telle couche de recouvrement permet de limiter les 30 déperditions énergétiques au niveau de la toiture-terrasse. La présente invention se rapporte également à une toiture solaire caractérisée en ce qu'elle comporte : - une toiture-terrasse, - une installation solaire conforme à l'invention, la couche de 35 recouvrement étant conformée pour recouvrir la toiture-terrasse, - des moyens de fixation, de préférence des sabots d'arrimage, conçus pour fixer le fond de chaque conduit à la toiture-terrasse. Dans un mode de réalisation, la toiture-terrasse s'étend suivant une direction oblique et chaque conduit s'étend suivant un axe longitudinal sensiblement perpendiculaire à la direction oblique de la toiture-terrasse. Un tel agencement des conduits permet d'optimiser la circulation des eaux de pluie de la surface des panneaux solaires vers les conduits. Avantageusement, les deux parois latérales se faisant face des conduits adjacents présentent des dimensions transversales conçues pour que les panneaux solaires s'étendent suivant une direction sensiblement parallèle à la direction oblique de la toiture-terrasse. Ainsi, un tel agencement des panneaux solaires, en conjugaison avec le caractère étanche de la toiture solaire, permet à la toiture solaire d'être éligible à la prime d'intégration au bâti, conformément à l'arrêté français du 12 janvier 2010 (NOR DEVE0930803A). La présente invention se rapporte enfin à un procédé de montage d'une installation solaire sur une toiture-terrasse, caractérisé en ce qu'il comporte les étapes successives consistant à : a) fournir une installation solaire conforme à l'invention, b) prévoir des moyens de fixation, de préférence des sabots d'arrimage, sur la toiture-terrasse, c) recouvrir la toiture-terrasse avec la couche de recouvrement isolante, d) disposer la pluralité de conduits ouverts sensiblement parallèles 25 entre eux sur la couche de recouvrement et fixer le fond de chaque conduit à la toiture-terrasse par l'intermédiaire des moyens de fixation, e) monter chaque panneau solaire sur les deux parois latérales se faisant face de deux conduits adjacents, f) relier longitudinalement les panneaux solaires entre eux de 30 manière étanche, de préférence par l'intermédiaire de traverses étanches. Ainsi, les conduits disposés lors de l'étape d) du procédé permettent de délimiter des zones de circulation pour des opérateurs afin de faciliter le montage des panneaux solaires lors de l'étape d) par ces opérateurs. 35 D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre d'un mode de réalisation d'une toiture solaire selon l'invention, donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective d'une toiture solaire selon l'invention, - la figure 2 est une vue en perspective de la toiture solaire illustrée à la figure 1, montrant une partie de l'intérieur de ladite toiture, - la figure 3 est une vue partielle en section transversale de la toiture illustrée à la figure 1. La toiture solaire illustrée aux figures 1 à 3 comporte une toiture- terrasse 1 sensiblement plane, et s'étendant sensiblement selon un axe horizontal. La toiture-terrasse 1 peut être réalisée en béton, en acier ou en bois par exemple. La toiture solaire comporte en outre une installation solaire comportant : - une couche de recouvrement 2 isolante recouvrant la toiture-terrasse 1 ; la couche de recouvrement 2 est posée sur une couche 3 comportant un pare-vapeur surmontant éventuellement un écran coupe-feu ; l'écran coupe-feu doit être notamment présent dans des établissements recevant du public, - des conduits 4 ouverts sensiblement parallèles entre eux disposés sur la couche de recouvrement 2, chaque conduit s'étendant suivant un axe longitudinal sensiblement horizontal, et comprenant deux parois latérales 40 reliées entre elles par un fond 41, - des panneaux photovoltaïques 5, chacun étant monté sur les deux parois latérales 40 se faisant face de deux conduits 4 adjacents, les panneaux photovoltaïques étant reliés longitudinalement entre eux par des traverses 50 assurant la continuité de l'étanchéité entre chaque panneau photovoltaïque. La couche de recouvrement 2 est réalisée dans un matériau isolant 30 thermique, de préférence du type polystyrène rigide. La toiture-terrasse 1 est équipée de sabots d'arrimage 6 formant des moyens de fixation conçus pour fixer le fond 41 de chaque conduit 4 à la toiture-terrasse 1. Chaque sabot d'arrimage 6 comporte : - un pied 60 fixé à la toiture-terrasse 1, et traversant la couche de 35 recouvrement 2, - une tête 61 sur laquelle est fixé le fond 41 d'un conduit 4. Thus, the presence of such open ducts makes it possible to evacuate the rainwater and to free itself from accumulations of rainwater on the solar panels, especially during inclement weather. Moreover, such ducts may be shaped to delimit traffic zones for operators in order to facilitate the assembly and maintenance of the solar panels by these operators. In addition, the fact that the solar panels are longitudinally connected to one another in a sealed manner, in conjunction with the presence of the insulating covering layer, makes it possible to avoid the formation of stagnant water areas, in particular under the panels. solar. In one embodiment, the two side walls of each duct each have at their free end a longitudinal flange on which is mounted the plurality of solar panels. Thus, such longitudinal flanges provide increased support surface and stability of the solar panels on the sidewalls. Advantageously, the two facing side walls of the adjacent ducts have transverse dimensions designed so that the plurality of solar panels extends in an oblique direction. Thus, the tilt of the solar panels obtained makes it possible to improve by gravity the flow of rainwater from the surface of the solar panels to the ducts. According to one embodiment, each duct comprises two lateral walls extending substantially along a vertical axis so as to form a substantially U-shaped cross section. According to a particular embodiment, the solar panels are connected longitudinally to one another by means of watertight ties. Advantageously, the insulating covering layer is made of a thermal insulating material, preferably of the rigid polystyrene type. Thus, such a covering layer makes it possible to limit the energy losses at the level of the roof terrace. The present invention also relates to a solar roof characterized in that it comprises: - a roof terrace, - a solar installation according to the invention, the covering layer being shaped to cover the roof terrace, - fixing means, preferably securing shoes, designed to fix the bottom of each duct to the roof terrace. In one embodiment, the flat roof extends in an oblique direction and each duct extends along a longitudinal axis substantially perpendicular to the oblique direction of the flat roof. Such an arrangement of the ducts makes it possible to optimize the circulation of rainwater from the surface of the solar panels to the ducts. Advantageously, the two side walls facing adjacent ducts have transverse dimensions designed for the solar panels extend in a direction substantially parallel to the oblique direction of the roof terrace. Thus, such an arrangement of the solar panels, in conjunction with the waterproof nature of the solar roof, allows the solar roof to be eligible for the building integration bonus, in accordance with the French Order of January 12, 2010 (NOR DEVE0930803A). The present invention finally relates to a method of mounting a solar installation on a roof terrace, characterized in that it comprises the successive steps of: a) providing a solar installation according to the invention, b) provide fixing means, preferably lashing shoes, on the flat roof, c) covering the flat roof with the insulating covering layer, d) arranging the plurality of open ducts substantially parallel to each other on the roofing layer; covering and fixing the bottom of each duct to the roof terrace through the fastening means, e) mount each solar panel on the two side walls facing two adjacent ducts, f) longitudinally connect the solar panels between them in a sealed manner, preferably via watertight crossbeams. Thus, the ducts arranged during step d) of the method allow the delimitation of circulation zones for operators in order to facilitate the mounting of the solar panels during step d) by these operators. Other features and advantages will appear in the following description of an embodiment of a solar roof according to the invention, given by way of non-limiting example, with reference to the accompanying drawings in which: FIG. 1 is a perspective view of a solar roof according to the invention, - Figure 2 is a perspective view of the solar roof shown in Figure 1, showing a portion of the interior of said roof, - Figure 3 is a partial cross-sectional view of the roof shown in Figure 1. The solar roof illustrated in Figures 1 to 3 comprises a roof terrace 1 substantially flat, and extending substantially along a horizontal axis. The roof terrace 1 can be made of concrete, steel or wood, for example. The solar roof further comprises a solar installation comprising: an insulating covering layer covering the roof terrace 1; the covering layer 2 is placed on a layer 3 comprising a vapor barrier possibly surmounting a fire screen; the fire shield must in particular be present in establishments receiving the public, - open conduits 4 substantially parallel to each other arranged on the covering layer 2, each duct extending along a substantially horizontal longitudinal axis, and comprising two walls; lateral 40 interconnected by a bottom 41, - photovoltaic panels 5, each being mounted on the two side walls 40 facing two adjacent ducts 4, the photovoltaic panels being connected longitudinally between them by cross members 50 ensuring the continuity of the watertightness between each photovoltaic panel. The covering layer 2 is made of a thermal insulating material, preferably of the rigid polystyrene type. The roof terrace 1 is equipped with lashing shoes 6 forming fastening means designed to fix the bottom 41 of each duct 4 to the roof terrace 1. Each lashing shoe 6 comprises: - a foot 60 fixed to the roof-terrace 1, and through the covering layer 2, a head 61 on which is fixed the bottom 41 of a duct 4.

Les conduits 4 sont réalisés sous la forme de chéneaux. Chaque conduit 4 comprend deux parois latérales 40 s'étendant sensiblement suivant un axe vertical de manière à former une section transversale sensiblement en forme de U. Les deux parois latérales 40 de chaque conduit 4 présentent chacune à leur extrémité libre un rebord longitudinal 400 sur lequel sont montés les panneaux photovoltaïques 5. De plus, les deux parois latérales 40 se faisant face des conduits 4 adjacents présentent des hauteurs différentes de sorte que les panneaux photovoltaïques 5 présentent un faible angle d'inclinaison relativement à l'horizontale de l'ordre de 5°. L'angle d'inclinaison des panneaux photovoltaïques 5 est choisi de manière à améliorer par gravité la circulation des eaux de pluie de la surface des panneaux photovoltaïques 5 vers les conduits 4, tout en veillant à ce que les panneaux photovoltaïques 5 s'étendent sensiblement parallèlement à la toiture-terrasse 1. The ducts 4 are made in the form of gutters. Each duct 4 comprises two lateral walls 40 extending substantially along a vertical axis so as to form a substantially U-shaped cross section. The two lateral walls 40 of each duct 4 each have at their free end a longitudinal flange 400 on which 5. In addition, the two side walls 40 facing adjacent ducts 4 have different heights, so that the photovoltaic panels 5 have a low angle of inclination relative to the horizontal of the order of magnitude. 5 °. The angle of inclination of the photovoltaic panels 5 is chosen so as to improve by gravity the flow of rainwater from the surface of the photovoltaic panels 5 to the ducts 4, while ensuring that the photovoltaic panels 5 extend substantially parallel to the roof terrace 1.

Le montage d'une telle installation solaire sur la toiture-terrasse 1 comporte les étapes successives consistant à : - équiper la toiture-terrasse 1 de sabots d'arrimage 6, - déposer éventuellement une couche 3 comportant un pare-vapeur surmontant un écran coupe-feu sur la toiture-terrasse 1, - recouvrir la toiture-terrasse 1 avec la couche de recouvrement 2, - disposer les conduits 4 sensiblement parallèles entre eux sur la couche de recouvrement 2 et fixer le fond 41 de chaque conduit 4 à la toiture-terrasse 1 par l'intermédiaire des sabots d'arrimage 6, - monter chaque panneau photovoltaïque 5 sur les deux parois 25 latérales 40 se faisant face de deux conduits 4 adjacents, - relier longitudinalement les panneaux photovoltaïques 5 entre eux par l'intermédiaire de traverses 50 étanches. Bien entendu, le mode de réalisation de l'invention décrit ci-dessus ne présente aucun caractère limitatif. Des détails et améliorations peuvent y 30 être apportés dans d'autres variantes d'exécution sans pour autant sortir du cadre de l'invention.
