Description

Panneau photovoltaïque Solar panel
L'invention concerne un panneau photovoltaïque, ainsi qu'une paroi de bâtiment fabriquée par assemblage de panneaux photovoltaïques plus particulièrement destinée à la fabrication de couvertures de bâtiments, sans toutefois y être limitée. Les systèmes photovoltaïques connus présentent généralement la forme de cadres supportant des cellules photovoltaïques, cadres qui sont rapportés sur la couverture des bâtiments, d'une façon indépendante de cette couverture.The invention relates to a photovoltaic panel, as well as a building wall manufactured by assembling photovoltaic panels more particularly intended for the manufacture of building covers, but without being limited thereto. The known photovoltaic systems generally have the form of frames supporting photovoltaic cells, frames that are reported on the roof of buildings, independently of this coverage.
Ces systèmes posent de nombreux problèmes, car la pose des cadres est rendue délicate par la fragilité des cellules. En outre, la pose de la couverture, puis des cellules, est réalisée en deux phases par deux corps de métier différents, ce qui diminue la productivité globale et engendre des problèmes de coordination sur les chantiers.These systems pose many problems because the setting of the frames is made delicate by the fragility of the cells. In addition, the laying of the cover, then the cells, is carried out in two phases by two different trades, which decreases the overall productivity and generates coordination problems on the sites.
Le raccordement des systèmes photovoltaïques au réseau électrique pose également problème, car les boîtiers et câbles de collecte de l'électricité générée doivent être protégés de l'humidité et acheminés au travers de la couverture existante, sans pour autant dégrader l'étanchéité de cette couverture.The connection of photovoltaic systems to the electricity grid is also problematic, as the boxes and cables for collecting the electricity generated must be protected from moisture and routed through the existing roof, without degrading the watertightness of this cover. .
Par ailleurs, la puissance fournie par ces systèmes commence à se dégrader lorsque leur température dépasse 9O0C pour chuter très fortement dès que l'on dépasse 1000C.Moreover, the power supplied by these systems begins to deteriorate when their temperature exceeds 9O 0 C to drop very strongly as soon as one exceeds 100 0 C.
Enfin, ces cadres munis de cellules étant rapportés et non intégrés à la couverture, peuvent dénaturer l'aspect du bâtiment ce qui peut être un frein majeur à l'obtention d'une autorisation administrative pour leur pose, dans certains secteurs.Finally, these frames with cells being reported and not integrated in the cover, can distort the appearance of the building which can be a major obstacle to obtaining an administrative license for their installation in certain sectors.
L'invention a donc pour but de mettre à disposition un système photovoltaïque ne présentant pas les inconvénients des systèmes de l'art antérieur et permettant en particulier de faciliter la pose sur le chantier, tant du point de vue mécanique qu'électrique, mais aussi préserver la puissance générée par les cellules.The purpose of the invention is therefore to provide a photovoltaic system that does not have the drawbacks of the systems of the prior art and which makes it possible in particular to facilitate the laying on the site of both the mechanical point of view than electrical, but also preserve the power generated by the cells.
A cet effet, un premier objet de l'invention est constitué par un panneau photovoltaïque comprenant un support métallique comportant au moins une surface plane percée d'une ouverture, au moins une cellule photovoltaïque fixée sur la surface plane du support au-dessus de l'ouverture, le panneau comprenant également au moins un connecteur électrique fixé sous la cellule au travers de l'ouverture et relié électriquement à celle-ci.For this purpose, a first object of the invention is constituted by a photovoltaic panel comprising a metal support having at least one plane surface pierced with an opening, at least one photovoltaic cell fixed on the flat surface of the support above the opening, the panel also comprising at least one electrical connector fixed under the cell through the opening and electrically connected thereto.

Si on considère tout d'abord les figures 1 et 2, on peut y voir un premier mode de réalisation d'un panneau photovoltaïque 1 selon l'invention. Ce panneau, de forme générale plane comprend un support métallique 2 et deux séries de cellules photovoltaïques fixées sur le support 2.If we first consider Figures 1 and 2, we can see a first embodiment of a photovoltaic panel 1 according to the invention. This generally flat panel comprises a metal support 2 and two series of photovoltaic cells fixed on the support 2.
Ce support métallique 2 qui est ici un profilé en acier galvanisé et prélaqué comprend deux ailes latérales 2a et 2e de forme similaire, en oméga. Il comprend également trois nervures de rigidification 2b, 2c et 2d, espacées régulièrement sur le support 2. Ces nervures présentent elles-aussi une forme en oméga similaire à celle des ailes latérales 2a et 2e. Les ailes latérales 2a et 2e ainsi que les nervures 2b, 2c et 2d ont des hauteurs identiques.This metal support 2 which is here a galvanized and prepainted steel profile comprises two side wings 2a and 2e of similar shape, in omega. It also comprises three stiffening ribs 2b, 2c and 2d, regularly spaced on the support 2. These ribs also have an omega shape similar to that of the lateral wings 2a and 2e. The lateral wings 2a and 2e as well as the ribs 2b, 2c and 2d have identical heights.
La forme de ces ailes latérales permet, lors de la pose, d'emboîter chaque panneau l'un sur l'autre par recouvrement des ailes, réalisant ainsi une excellente étanchéité. La zone de recouvrement des ailes est également l'emplacement privilégié pour la solidarisation des panneaux par des moyens de fixation adaptés.The shape of these side wings allows, during installation, to fit each panel one over the other by covering the wings, thus achieving an excellent seal. The wing covering area is also the preferred location for the fastening of the panels by suitable fastening means.
Le panneau photovoltaïque 1 comprend également, en particulier, une première série de quatre éléments photovoltaïques 3, 4, 5 et 6 qui ont une forme rectangulaire et sont insérées dans l'espace existant entre les nervures de rigidification 2b, 2c et 2d du support 2.The photovoltaic panel 1 also comprises, in particular, a first series of four photovoltaic elements 3, 4, 5 and 6 which have a rectangular shape and are inserted in the space existing between the stiffening ribs 2b, 2c and 2d of the support 2 .
Ces éléments photovoltaïques 3, 4, 5 et 6 sont composés d'un assemblage de cellules photovoltaïques au silicium, par exemple, qui sont prises en sandwich entre une feuille de verre en face supérieure et une feuille de polymère de type TEDLAR® en face inférieure formant ainsi une structure laminée. De tels laminés photovoltaïques peuvent comprendre différentes autres couches de matériaux polymères ou autres et sont connus en eux- mêmes. II est bien entendu que les cellules photovoltaïques utilisables pour le panneau selon l'invention peuvent être de toute nature, telle que par exemple, des cellules dont le semi-conducteur est le silicium, sous forme mono ou polycristalline. Comme on peut le voir en figure 2 et 3, le panneau 1 comprend également, sur sa face inférieure, des connecteurs électriques 7, 8, 9 et 10 raccordés respectivement aux éléments photovoltaïques 3, 4, 5 et 6 au travers d'ouvertures rectangulaires 11 qui ont été préalablement pratiquées dans le support métallique 2. Ces connecteurs 7, 8, 9 et 10 sont des éléments connus en eux-mêmes qui sont généralement pré-assemblés par collage et connectés électriquement avec les éléments photovoltaïques correspondants lors de la fabrication de ces éléments. ;These photovoltaic elements 3, 4, 5 and 6 are composed of an assembly of silicon photovoltaic cells, for example, which are sandwiched between a glass sheet on the upper face and a sheet of TEDLAR® type polymer on the lower face. thus forming a laminated structure. Such photovoltaic laminates may comprise various other layers of polymeric or other materials and are known per se. It is understood that the photovoltaic cells that can be used for the panel according to the invention can be of any kind, such as, for example, cells whose semiconductor is silicon, in mono or polycrystalline form. As can be seen in FIGS. 2 and 3, the panel 1 also comprises, on its underside, electrical connectors 7, 8, 9 and 10 respectively connected to the photovoltaic elements 3, 4, 5 and 6 through rectangular openings. 11 These connectors 7, 8, 9 and 10 are elements known in themselves which are generally pre-assembled by gluing and electrically connected with the corresponding photovoltaic elements during the manufacture of FIG. these elements. ;
Comme on peut le voir en figure 4, les connecteurs 10 sont munis de deux bornes de raccordement 10a, 10b. Ces bornes permettent de relier les éléments photovoltaïques entre eux, en série comme en parallèle par l'intermédiaire de câbles de raccordement 13. Elles peuvent également permettre de raccorder l'ensemble du panneau 1 aux autres panneaux de la paroi par l'intermédiaire de câbles de raccordement 12 et 14. Ces connecteurs peuvent également comprendre des systèmes de diodes connus en eux-mêmes, qui permettent de mettre hors-circuit un élément, lorsque celui-ci de produit pas de courant, soit en raison d'une défaillance de l'élément, soit pour des raisons naturelles (nuage, neige sur le panneau, etc.). De tels connecteurs sont connus et en vente dans le commerce.As can be seen in FIG. 4, the connectors 10 are provided with two connection terminals 10a, 10b. These terminals make it possible to connect the photovoltaic elements together, in series as well as in parallel by means of connection cables 13. They can also make it possible to connect the whole of the panel 1 to the other panels of the wall by means of cables These connectors may also include diode systems known per se, which make it possible to switch off an element when it produces no current, or because of a failure of the circuit. element, either for natural reasons (cloud, snow on the panel, etc.). Such connectors are known and commercially available.
On voit également que la première série d'éléments photovoltaïques 7, 8, 9 et 10 est placée tête-bêche par rapport à la deuxième série de d'éléments photovoltaïques portés par le support métallique 1 , ce qui permet de faciliter les raccordements de chacune des séries, sans juxtaposition de câbles. Les panneaux photovoltaïques selon l'invention peuvent donc être fabriqués, par exemple, à partir d'un support métallique que l'on perce d'ouvertures. Puis on enduit le support de colle à froid, par exemple, et l'on pose les éléments photovoltaïques munis de leurs connecteurs au-dessus de ces ouvertures, de telle sorte que les connecteurs passent au travers de celles-ci. On presse ensuite le tout pour solidariser l'ensemble. On pourra ajouter à la colle à froid des produits accélérateurs de prise classiques qui permettront de réduire le temps de fabrication. Un tel procédé est avantageux car il permet d'obtenir un panneau présentant , une bonne stabilité dimensionnelle, avec une fabrication industrielle en atelier. En outre, les surfaces des éléments photovoltaïques et du support métallique étant ainsi en contact étroit, la chaleur des éléments photovoltaïques est transmise efficacement au support qui peut la répartir sur toute sa surface, en raison de sa bonne conductivité. On peut ainsi éviter toute surchauffe locale et donc améliorer la puissance fournie par le système. On préférera en outre utiliser un procédé de collage à l'aide d'une colle permettant le transfert de chaleur des cellules vers le support métallique.It can also be seen that the first series of photovoltaic elements 7, 8, 9 and 10 is placed upside down relative to the second series of photovoltaic elements carried by the metal support 1, which facilitates the connections of each series, without juxtaposition of cables. The photovoltaic panels according to the invention can therefore be manufactured, for example, from a metal support which is pierced with openings. Then the adhesive is coated cold, for example, and we put the photovoltaic elements with their connectors above these openings, so that the connectors pass through them. We then press everything to secure the assembly. The cold glue may be supplemented with conventional setting accelerators that will reduce manufacturing time. Such a method is advantageous because it makes it possible to obtain a panel having good dimensional stability, with industrial manufacturing in the workshop. In addition, the surfaces of the photovoltaic elements and the metal support being thus in close contact, the heat of the photovoltaic elements is efficiently transmitted to the support which can distribute it over its entire surface, because of its good conductivity. It can thus avoid any local overheating and thus improve the power provided by the system. It will further be preferred to use a gluing process using an adhesive for transferring heat from the cells to the metal support.
Il est bien entendu possible de solidariser les éléments photovoltaïques sur le support métallique par tout moyen adapté, comme par exemple une colle à chaud ou une fixation mécanique.It is of course possible to secure the photovoltaic elements on the metal support by any suitable means, such as hot glue or mechanical fastening.
Si on considère à présent la figure 5, on peut y voir une couverture de bâtiment en cours de pose à l'aide de panneaux photovoltaïques selon l'invention. En particulier, le bâtiment comprend une série de pannes P horizontales constituant la structure primaire de la couverture. Sur ces pannes P est posée une série de panneaux sandwichs métalliques 15 à parement nervure qui forment une première surface de couverture sur laquelle peuvent être fixés des pièces métalliques horizontales 16, 17 et 18, régulièrement espacées. C'est sur ces pièces qu'est alors fixé le panneau photovoltaïque 20 selon l'invention. Ce panneau comporte des éléments photovoltaïques sur une partie seulement de sa surface, car il s'agit d'un panneau d'extrémité.If we now consider Figure 5, we can see a building cover being laid using photovoltaic panels according to the invention. In particular, the building comprises a series of horizontal P purlins constituting the primary structure of the cover. On these purlins P is placed a series of metal sandwich panels 15 with a rib facing which form a first surface on which can be fixed horizontal metal parts 16, 17 and 18, regularly spaced. It is on these parts that the photovoltaic panel 20 according to the invention is then fixed. This panel has photovoltaic elements on only part of its surface, because it is an end panel.
Si on considère la figure 6, on peut y voir en particulier la pièce 16 qui est un profilé écarteur permettant tout d'abord la pose et la fixation du panneau 20 par des moyens classiques. On voit qu'il est également percé d'ouvertures rectangulaires sur ces deux faces latérales. Ces ouvertures permettent de faire passer les câbles de connexion sortant des panneaux et de les guider ainsi jusqu'au bas de la paroi fabriqué où ils sont rassemblés et connectés au réseau électrique. Le profilé écarteur peut ainsi prendre la forme générale d'un U comme c'est le cas pour la pièce 16, mais il peut également prendre la forme générale d'un Z comme on le voir pour l'écarteur 19 qui comprend lui-aussi des ouvertures de passage des câbles. Mais, la fonction essentielle des profilés écarteurs 16 ou 19 est qu'ils permettent aussi de réaliser un espace de ventilation en sous face des panneaux photovoltaïques, ce qui permet de réguler davantage leur température et donc d'éviter toute surchauffe locale. Cette ventilation peut également permettre d'éviter toute condensation d'humidité en sous face des panneaux selon l'invention.If we consider Figure 6, we can see in particular the part 16 which is a spacer profile allowing first of all the installation and fixing of the panel 20 by conventional means. It can be seen that it is also pierced with rectangular openings on these two lateral faces. These openings allow the connecting cables coming out of the panels to pass and thus guide them to the bottom of the manufactured wall where they are assembled and connected to the electrical network. The spacer profile can thus take the general shape of a U as is the case for the part 16, but it can also take the general shape of a Z as can be seen for the spacer 19 which also includes cable openings. However, the essential function of the spacer profiles 16 or 19 is that they also make it possible to create a ventilation space in the underside of the photovoltaic panels, which makes it possible to further regulate their temperature and thus to avoid any local overheating. This ventilation can also make it possible to avoid condensation of moisture on the underside of the panels according to the invention.
Pour garantir l'absence de condensation, on pourra poser un revêtement absorbant et drainant en sous face des panneaux selon l'invention.To guarantee the absence of condensation, it will be possible to lay an absorbent and draining coating on the underside of the panels according to the invention.
Si on considère la figure 7, on peut voir une couverture de bâtiment en cours de pose avec une représentation des flux d'airs sous forme de flèches. On voit que l'air froid entrant en bas de toiture peut circuler le long des panneaux et ressortir chaud, par exemple, au niveau de la faitière.If we consider Figure 7, we can see a building cover being laid with a representation of the airflow in the form of arrows. It can be seen that the cold air entering the roof can circulate along the panels and come out hot, for example, at the level of the ridge.
Pour optimiser cette ventilation, on pourra en outre utiliser des éléments de finition ventilés tels que la chatière de ventilation 23 représentée en figure 8 et posée sur un profilé métallique 22. Ce profilé 22 présente une forme compatible avec les supports métalliques des panneaux selon l'invention, pour pouvoir être intégré facilement à la paroi en cours de construction. Ce type de chatière 23 sera plus particulièrement utilisé pour des parois d'une superficie importante, nécessitant une ventilation intermédiaire, ou pour des couvertures de bâtiments ne comportant qu'un pan de toiture, sans faitière.To optimize this ventilation, it will further be possible to use ventilated finishing elements such as the ventilation flap 23 shown in FIG. 8 and placed on a metal profile 22. This profile 22 has a shape that is compatible with the metal supports of the panels according to FIG. invention, to be easily integrated into the wall being built. This type of flap 23 will be more particularly used for walls of a large area, requiring intermediate ventilation, or for roofs of buildings with only one side of roof, without factaire.
Pour la réalisation d'une couverture de bâtiment traditionnel à deux pans, on pourra ainsi utiliser une faitière métallique ventilée 24 telle que celle présentée en figure 9. Cette faitière comprend notamment des ouvertures latérales 25 sous forme de vantelles, par exemple. Pour éviter d'endommager les panneaux et de les faire fonctionner avant la pose, on disposera de préférence un film noir opaque sur les cellules, que l'ouvrier pourra retirer après la pose, rendant ainsi le système immédiatement et facilement opérationnel. Si on considère à présent les figures 10 et 11 , on peut y voir un deuxième mode de réalisation d'un panneau 31 selon l'invention. Ce panneau 31 se compose tout d'abord d'un profilé métallique 32 comportant trois nervures de rigidification 32b, 32c et 32d en forme d'oméga. La nervure centrale 32c présente une hauteur supérieure à celle des deux autres nervures 32b et 32d. Cette hauteur plus importante permet de conférer une bonne rigidité au panneau 31 , tandis que les hauteurs réduites des nervures 32b et 32d permettent de réduire l'ombre portée de ces éléments sur les cellules photovoltaïques. Des essais de performance électrique ont établis que le gain en terme de puissance électrique ainsi obtenue pouvait se monter à 5%, ce qui est considérable.For the realization of a traditional building roof with two sides, it will thus be possible to use a metal ventilated well 24 such as that shown in FIG. 9. This factaire comprises in particular side openings 25 in the form of leaves, for example. To avoid damaging the panels and making them work before installation, an opaque black film will preferably be placed on the cells, which the worker will be able to remove after installation, thus making the system immediately and easily operational. If we now consider Figures 10 and 11, we can see a second embodiment of a panel 31 according to the invention. This panel 31 is firstly composed of a metal section 32 having three stiffening ribs 32b, 32c and 32d shaped omega. The central rib 32c has a height greater than that of the other two ribs 32b and 32d. This greater height makes it possible to confer a good rigidity on the panel 31, while the reduced heights of the ribs 32b and 32d make it possible to reduce the shadow of these elements on the photovoltaic cells. Electrical performance tests have established that the gain in terms of electrical power thus obtained could amount to 5%, which is considerable.
Le profilé métallique 32 comprend également deux ailes latérales 32a et 32e de forme et de taille similaire à celle de la nervure centrale 32c. La forme de ces ailes permet d'emboîter chaque panneau* l'un sur l'autre par recouvrement des ailes, réalisant ainsi une excellente étanchéité. La zone de recouvrement des ailes est également l'emplacement privilégié pour la solidarisation des panneaux par des moyens de fixation adaptés.The metal section 32 also comprises two lateral wings 32a and 32e of shape and size similar to that of the central rib 32c. The shape of these wings allows to fit each panel * one over the other covering the wings, thus achieving an excellent seal. The wing covering area is also the preferred location for the fastening of the panels by suitable fastening means.
Le panneau 31 est également composé de deux séries de quatre éléments photovoltaïques référencés 33, 34, 35 et 36 pour la première série et 37, 38, 39 et 40 pour la deuxième série.The panel 31 is also composed of two series of four photovoltaic elements referenced 33, 34, 35 and 36 for the first series and 37, 38, 39 and 40 for the second series.
Ces différents éléments photovoltaïques sont analogues à ceux décrits pour le premier mode de réalisation et sont fixés entre les différentes nervures de rigidification du profilé 32.These different photovoltaic elements are similar to those described for the first embodiment and are fixed between the various stiffening ribs of the section 32.
Le support métallique pourra en particulier prendre la forme des profilés des figures 2 et 11, mais ne se limite pas à ses formes de réalisation optimisées. Il est en particulier possible d'utiliser tout profilé ou tout système de profilé permettant d'obtenir une rigidité suffisante de l'ensemble pour permettre sa manutention et sa mise en place par un ouvrier du bâtiment.The metal support may in particular take the form of the profiles of Figures 2 and 11, but is not limited to its optimized embodiments. It is in particular possible to use any profile or profile system to obtain sufficient rigidity of the assembly to allow its handling and its implementation by a construction worker.
La surface de fixation des cellules sera plane, mais cette surface pourra en particulier être plate ou inclinée, ou bien être une combinaison de ces deux formes, en fonction notamment de la pente de la toiture à équiper. Un des avantages importants du système est qu'il permet de faire appel à des couvreurs de profilés métalliques formés aux règles professionnelles classiques pour la pose de la couverture, car, la connectique étant déjà présente, il suffit de poser le support métallique muni des cellules selon les règles de l'art du bâtiment et de brancher les sorties des panneaux photovoltaïques au circuit électrique du bâtiment ou de l'installation pour que l'ensemble fonctionne.The fixing surface of the cells will be flat, but this surface may in particular be flat or inclined, or be a combination of these two forms, depending in particular on the slope of the roof to be equipped. One of the important advantages of the system is that it makes it possible to call upon roofers of metal profiles formed to the traditional professional rules for the laying of the cover, because, since the connectors are already present, it suffices to place the metallic support provided with the cells. according to the rules of the building industry and connect the outputs of the photovoltaic panels to the electrical circuit of the building or installation for the whole system to work.
En outre, malgré la fragilité des cellules photovoltaïques, lorsqu'elles sont solidarisées sur le support métallique, il est possible pour les ouvriers de marcher dessus sans les endommager grâce à la rigidité importante du profilé.In addition, despite the fragility of photovoltaic cells, when they are secured to the metal support, it is possible for workers to walk on without damaging them due to the significant rigidity of the profile.
Ceci permet donc de circuler sur la couverture lors dé sa fabrication et rend plus facile sa fixation et la réalisation des raccordements électriques.This allows to circulate on the cover during its manufacture and makes it easier to secure and the realization of electrical connections.
Les panneaux selon l'invention peuvent être utilisés en tant que couverture supplémentaire (sur-couverture) venant couvrir une couverture de toit existante, que celle-ci assure une étanchéité correcte ou non. Ils sont cependant avantageusement utilisés comme seule couverture étanche du bâtiment concerné.The panels according to the invention can be used as additional cover (on-cover) coming to cover an existing roof covering, whether it provides a correct seal or not. They are, however, advantageously used as the only waterproof cover of the building concerned.
Ils pourront être employés en rénovation comme' en construction neuve et s'applique notamment à la réalisation de couvertures de bâtiments industriels, de bâtiments professionnels, de bâtiments résidentiels collectifs ou individuels. Ils peuvent également être utilisés pour couvrir une zone à protéger des intempéries, tel qu'un parking ou une zone de stockage agricole, par exemple. They can be employed in renovation as ' under new construction and applies in particular to the realization of blankets of industrial buildings, professional buildings, residential buildings collective or individual. They can also be used to cover an area to be protected from bad weather, such as a parking lot or an agricultural storage area, for example.
