    [0002] Such tiles are known, for example from WO2011004092, which describes a rectangular tile which has interlocking overlapping edges on its short sides and on its long sides. In addition, an electrical connection of a tile to the adjacent tile, to connect them in series or in parallel, is performed by electrical connectors which fit together when the overlapping edges are positioned to fit themselves by interlocking. . Also known from W000 / 30184 a photovoltaic tile in which rubber is used to close the panel which is in two parts. Document US 2006/0266406 also discloses a photovoltaic tile whose body is made of elastomer. However, these documents do not address a problem that arises when the photovoltaic surface is subjected to a rise in temperature or temperature differences, during the use of the surface for the production of electricity. Some structures then see losses of electrical contact between adjacent tiles, due to deformations that occur under heat, caused in particular by the differential expansion undergone by the various materials of the tiles.

    [0003] The invention may furthermore have some of the following advantageous features: the mutual engagement of the first and second electrical connection means may be in a direction transverse to the mean plane of the panel, the interposing element may have a generally oblong shape in the middle plane of the panel, elongated parallel to an edge of the panel, - the interposer may be rubber or hytrel (registered trademark), or any other elastomeric material, synthetic or natural, the interposing element may comprise two passages for passing each of an electric contactor to establish the electrical connection between the panel and the adjacent panel; the interposition element may comprise at least one female cylinder cooperating with a cylinder; male made of rigid material of the second electrical connection means, formed in the body of the panel, 3033461 3 - the first and second electrical connection means may define a single electrical connection zone located on a portion of an elongated edge of the panel, the first and second electrical connection means may define an electrical connection zone on the short sides of the panels, being rectangular, the reciprocal engagement may be in a direction perpendicular to a bearing surface of the adjacent panel on the panel, said bearing surface being oblique with respect to the lower surface of the panel, and on the upper surface of the panel. panel, - a photovoltaic surface of the panel may be flat or corrugated. The panel may further comprise an integrated AC DC converter, or conversely, provide at its terminals a DC current. The body may comprise a shell in two parts containing means of thermal insulation and electrical energy management. List of Figures The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the following explanatory description made with reference to the accompanying drawings given solely by way of illustrative example. an embodiment of the invention and in which: - Figure 1 shows a general view of a tile according to one embodiment of the invention. FIG. 2 shows a detailed view of the manufacture of the tile of FIG. 1. FIG. 3 (FIG. 3A and FIG. 3B) shows the precise geometry of an element of the tile of FIG. FIG. 4 shows a sectional view of the placement of the element of FIG. 3. FIG. 5 shows, in the same section, two tiles connected to one another. DESCRIPTION OF AN EMBODIMENT With reference to FIG. 1, a photovoltaic tile 100 is shown. It has a generally rectangular shape, parallel to a laying plane on which it is configured to be laid. On an upper face of the tile 100, there is a photovoltaic surface 110. On the opposite (lower) surface of the photovoltaic tile 100 is a laying surface 115, defining the laying plane, for placing on a structure such as the frame of a roof. The photovoltaic tile has a first long-side lap edge 120 and a second long-edge lap edge 130, opposite the first edge 120. The tile has more than one small lap edge 140 and a second side overlap edge 150 opposed to the first edge 140. The first and second edges 120 and 130 allow tile assembly in a row of tiles extending parallel to the short side of the tile 100, by nesting nesting shapes present on the lower surface of the first edge 120, in nesting shapes present on the upper face of the second edge 130. The first and second edges 140 and 150 allow, for their part, the juxtaposition of identical photovoltaic tiles 100 in a direction of alignment parallel to the long side of the tile 100, by interleaving a form of nesting present on the lower face of the second bor d 150 in a form of nesting present on the upper face of the first edge 140. Thus, it is possible to set up a juxtaposition of similar photovoltaic tiles in two directions of development perpendicular to each other, constituting thus a photovoltaic surface consisting of elementary tiles.
    [0004] The first one-sided lap edge 140 includes on its upper surface a first electrical connector 160 not far from a corner of the tile 100 and the long-side lap edge 130. This is surrounded by a support surface 180 extending the full length of the small side for supporting an adjacent photovoltaic tile on the photovoltaic tile 100. The second side overlap edge 150 comprises an opposed bearing surface at the bearing surface 180. This opposite bearing surface has, at a height corresponding to the height of the first electrical connector 160, a second electrical connector 170 (not visible, but which can be seen in FIG. 5), intended to interact with the first electrical connector 160 during the installation of two photovoltaic tiles 100 juxtaposed in the alignment direction parallel to the long side.
    [0005] The first and second electrical connection means 160 and 170 define a single electrical connection area located on a portion of the first one-sided lap edge 140 and a corresponding portion of the second one-sided lap edge 150. The body of the the tile comprises a shell in two parts, optionally made of rigid organic composite materials, and containing, in some embodiments, means of thermal insulation, and possibly management and optimization of the electrical energy produced, such as a built-in AC DC converter or remote control and maintenance means 20 of the tile. FIG. 2 shows a view of the assembly of the first electrical connector 160. The support surface 180 is recognized, which is traversed by an oblong aperture 190 elongated parallel to the short side of the photovoltaic tile 100. The opening 190 allows the placement of an interposing and connecting member 200 of rubber, or other elastomeric material, or other elastic flexible material, for example a synthetic material, or a natural material. Hytrel is also used in a particular embodiment, for its properties both elastomeric and thermoplastic. A suitable Hytrel grade will be chosen according to the expected temperature variations, as well as mechanical stresses.
    [0006] In the view of Figure 2, there is shown the interposing element and connection 200 during its establishment, to the right of the opening 190 away from it, above the surface The interposing and connecting element 200 also has a generally oblong shape in a plane parallel to the bearing surface 180 and dimensions enabling it to be inserted into the opening 190 by embedding. More specifically, the circumference of the interposing and connecting element 200 carries a groove which, during the installation in the opening 190, receives a rib of the body of the photovoltaic tile 100, 10 for the joining of the interposition and connection element 200 to the body of the photovoltaic tile 100. In FIG. 3 (FIG. 3A and FIG. 3B), the geometry of the interposition and connection element 200 is represented in greater detail. it comprises on one side of the plane of the oblong shape an open mouth 210. On the other side of the plane of oblong shape, bottom bottom 220 is present, substantially solid. On the circumference of the oblong shape, parallel to the plane thereof, a groove 260 circumscribes the interposing and connecting element 200. In addition, two embedding cylinders 230 and 240, aligned parallel to the elongation direction of the oblong shape are present in the interior volume of the interposing and connecting element 200. They are fixed on the bottom bottom 220, have a generatrix perpendicular to the plane of the oblong shape, and have a open mouth on the side of the wide upper mouth 210. In contrast to their open mouth, these recess cylinders 230 and 240 have narrow passages for electrical contactors 235 and 245. The cylinders 230 and 240 are for example cylinders of revolution, and the passages 235 and 245 are constituted by circular openings in the center of a closed surface constituting a cross section of the cylinders 230 and 240.
    [0007] FIG. 4 shows, in sectional view, the positioning of the interposition and connection element 200 in the body of the photovoltaic tile 100. In this figure, the fixing rib 195 is shown. in the fixing groove 260 of the interposing and connecting element 200. The open mouths of the embedding cylinders 230 and 240 are arranged on the side of the photovoltaic surface 110, whereas the passages for the electrical contactors 235 and 245 are placed on the side of the laying surface 115.
    [0008] It can be seen in this figure that the bearing surface 180 is inclined with respect to the upper and lower surfaces of the tile, here the laying surface 115 and the photovoltaic surface 110. The bearing surface 130 approaches, as seen in FIG. cutting the figure, from the laying surface 115 to the approach of the second long-side lap edge 130, and away from the first long-edge lap edge 120. Figure 5 shows a detail view, in section, of a set of two tiles connected to one another using the first electrical connector 160 and second electrical connector 170. The view is presented in the same sectional plane as FIG. the second photovoltaic tile corresponds to the references used for the first photovoltaic tile, incremented by 1000. The second connector 1170 comprises two recessing cylinders 1172 and 1174 formed in the material of the horn ps of the photovoltaic tile 1100. These two recessing cylinders 1172 and 1174 20 fit into the recessing cylinders 230 and 240 of the interposing and connecting element 200. The opposite bearing surface 1185 of the second photovoltaic tile 1100 is in contact with the bearing surface 180 of the first photovoltaic tile 100.
    [0009] The electrical connection is by unrepresented electrical contactors, brought into contact by interlocking the recessing cylinders 230 and 240 on one side and 1172 and 1174 on the other side. Two separate electrical contacts are established, one by means of the recessing cylinders 230 and 1172, and the other using the recessing cylinders 240 and 1174. The cylinders 230 and 240 are female cylinders cooperating with the male cylinders 1172 and 1174 made of rigid material formed in the body of the panel.
    [0010] The passages 235 and 245 of the interposing and connecting element 200 each pass an electrical contactor to establish the electrical connection between the panel and the adjacent panel. More generally, the first and second electrical connection means 160 and 170 are reciprocally engaged with each other, and this engagement is made in a direction perpendicular to the bearing surface 180 and therefore transverse in the middle plane of the tile 100, or at its laying plane. The interposing and connecting element 200 is thus interposed between the body of the tile and the body of the adjacent tile, participates in the joining of the two tiles while absorbing, during the use of the tiles to produce the tiles. photovoltaic electricity, relative movements caused by differential thermal expansion of tile elements. The invention is not limited to the embodiment shown but extends to all variants within the scope of the claims. It is specified in particular that the photovoltaic surface 110 of the panel may be not flat but undulating, without this modifying the principles of mechanical and electrical connection on the edges of the tile.
