MOUNTING SYSTEM FOR ATTACHING AT LEAST ONE PHOTOVOLTAIC PANEL TO A ROOF

Description

Domaine technique

[0001] The present invention relates to the field of so-called sloping roofs made from interlocking terracotta tiles, but also from concrete, or even from composite material, and more particularly to the fixing of photovoltaic panels on such a roof. Etat de la technique

[0002] There are several known ways to equip a roof with photovoltaic panels.

[0003] For example, according to a first solution, photovoltaic panels can be installed on top of a roof with highly curved interlocking tiles. However, this solution has a detrimental effect on the overall aesthetics of the roof since the photovoltaic panels then protrude from the roof. In addition, fixing the photovoltaic panels can compromise the waterproofing of the roof, since it requires passing through the layer of tiles with fixing devices intended to be fixed to the roof frame. In addition, the photovoltaic panels, which protrude from the roof, present a significant wind resistance.

[0004] A second known solution consists of interrupting the layer of tiles on a surface corresponding substantially to that of the photovoltaic panels to be fixed on the roof, positioning the photovoltaic panels in the interrupted area of ​​the layer of tiles, fixing the photovoltaic panels to the frame, and then positioning accessory tiles around the perimeter of the photovoltaic panels. Such a solution is described in particular in document DE102011106212.

[0005] Document DE102011106212 describes more particularly a set of accessory tiles comprising in particular accessory tiles of a first type configured to extend along an upper edge of a photovoltaic panel and to cooperate each with a standard tile belonging to a row arranged immediately above the photovoltaic panel, accessory tiles of a second type configured to extend along a lower edge of the photovoltaic panel and to cooperate each with a standard tile belonging to a row arranged immediately below the photovoltaic panel, and accessory tiles of a third type configured to extend along a lateral edge of the photovoltaic panel and to cooperate each with an adjacent standard tile.

[0006] This solution significantly reduces the height at which the photovoltaic panels protrude from the roof, thus limiting their impact on the overall appearance of the roof. Furthermore, this solution limits the wind resistance caused by the photovoltaic panels.

[0007] However, such a solution has the major disadvantage of transferring part of the roof's waterproofing to the photovoltaic panels, which is likely to compromise the overall waterproofing of the roof.

[0008] Another example of a fastening system is known from US 2020 / 399902 A1. Résumé de l'invention

[0009] The invention aims to remedy all or part of the aforementioned drawbacks and in particular to propose a fixing system allowing the installation and integration of a photovoltaic panel on a roof while guaranteeing easy mounting on the roof which respects the overall aesthetics of the roof and the waterproofing of the roof.

[0010] To this end, the present invention relates to a fixing system configured to fix at least one photovoltaic panel on a roof comprising a plurality of rows of standard interlocking tiles, the standard interlocking tiles each comprising an external face facing the sky and an internal face facing a frame and being laid on rows of battens of the frame, the standard interlocking tiles each comprising at least one longitudinal curve whose cross-section is in the shape of an inverted U, the fixing system comprising: downstream accessory interlocking tiles of a first type, each downstream accessory interlocking tile comprising: a lower part which is provided with a foot edge and which is configured to bear on a head edge of a standard interlocking tile belonging to an immediately lower row, said lower part being provided with at least one lower curve whose cross-section is in the shape of an inverted U and which is configured to partially cover the longitudinal curve of the standard interlocking tile belonging to the immediately lower row, and an upper part which is provided with a head edge and which has a maximum height less than 70%, and for example less than 60%, of the maximum height of the lower curve of each of the downstream accessory interlocking tiles, flattened accessory interlocking tiles of a second type which are different from the downstream accessory interlocking tiles and the standard interlocking tiles,each flattened accessory interlocking tile having a maximum height less than 70%, and for example less than 60%, of the maximum height of the lower curve of each of the downstream accessory interlocking tiles, each flattened accessory interlocking tile comprising a foot edge configured to bear on a head edge of a downstream accessory interlocking tile belonging to an immediately lower row and a head edge configured to be covered both by a foot edge of a flattened accessory interlocking tile and by a foot edge of a standard interlocking tile belonging to an immediately higher row, a lower support rail and an upper support rail configured to bear respectively on upper faces of two battens belonging to two different rows, and to be fixed to the frame,a plurality of fixing members comprising a first set of fixing members configured to be fixed to the lower support rail and a second set of fixing members configured to be fixed to the upper support rail, each of the fixing members of the first set being configured to extend between a respective downstream accessory interlocking tile and a respective flattened accessory interlocking tile belonging to two successive rows and to project from the toe edge of the respective flattened accessory interlocking tile, and each of the fixing members of the second set being configured to extend between two respective flattened accessory interlocking tiles belonging to two successive rows and to project from the toe edge of the respective flattened accessory interlocking tile belonging to the upper row of said two successive rows,and a support device configured to be attached to the fixing members of the first and second sets and to be supported by the fixing members of the first and second sets, the support device being configured to extend above downstream and flattened accessory interlocking tiles and to support at least one photovoltaic panel.,

[0011] Such a configuration of the fixing system according to the present invention, and in particular of the downstream and flattened accessory interlocking tiles, makes it possible to ensure the waterproofing of the roof solely by means of tiles.

[0012] In addition, the particular structure of the flattened accessory interlocking tiles and the upper parts of the downstream accessory interlocking tiles allows a photovoltaic panel to be partially embedded in the roof, and therefore significantly limits the height by which such a photovoltaic panel protrudes from the roof.

[0013] In addition, the use of lower and upper guide rails, fixing members and a support device for fixing the photovoltaic panel to the frame ensures easy and quick fixing of a photovoltaic panel on a roof.

[0014] Finally, since the support device (on which the photovoltaic panel is fixed) is fixed and supported by the frame (via the lower and upper support rails and the fixing members), the roof, formed by the standard interlocking tiles and the downstream and flattened accessory interlocking tiles, does not support the photovoltaic panel and is therefore not likely to be weakened by the presence of the latter.

[0015] Consequently, the fixing system according to the present invention allows the installation and integration of a photovoltaic panel on a roof while guaranteeing easy mounting on the roof which respects the overall aesthetics of the roof and the waterproofing of the roof.

[0016] According to one embodiment of the invention, the support device is configured to allow the photovoltaic panel to be installed in portrait format and / or landscape format.
