1. A flat photovoltaic tile intended to form a covering for a pitched roof by juxtaposing a set of tiles in partial edge-to-edge overlap, the tile including a shell and at least one flat photovoltaic power generation element, the shell being rigid and made of plastic material, the photovoltaic element being fastened in a housing formed in the shell thickness, the tile having two opposite faces and four edges:
a front face and a rear face, the front face being intended to receive a solar radiation,
an upstream edge and a downstream edge, opposite and parallel to each other, the upstream edge being intended to be installed higher than the downstream edge in the pitched roof covering, an upstream part located along the upstream edge of the tile being intended to be overlapped by a downstream part located along the downstream edge of at least another tile of the covering,
a right lateral edge and a left lateral edge, opposite and parallel to each other, two lateral parts along the two right and left lateral edges being intended to respectively overlap and be overlapped by lateral parts of the left and right lateral edges, respectively, of two other adjacent tiles of a same row of tiles of the covering,
the overlapping lateral parts of the tiles as well as the overlapping upstream part and downstream part of the tiles being configured in such a way as to ensure watertightness to at least the liquid water flowing on the roof,
the photovoltaic element forming a power generation area, the tile being configured in such a way that the power generation area extends over the tile outside of the tile parts that are intended to be overlapped, the tile further including an electrical connection means for exporting the power generated by the photovoltaic element,
the rear face including, towards the upstream edge, at least one tenon protruding rearward from the flat general extent of the rear face, said at least one tenon being intended to hold the tile on a holding device, and
on the one hand, in the power generation area, the tile includes, in thickness, from the rear face towards the front face:
a shell part,
a rear panel,
a lower Ethylene Vinyl Acetate film,
at least one silicon-based photovoltaic conversion plate,
an upper Ethylene Vinyl Acetate film, and
a transparent layer consisted of tempered glass, and
on the other hand, outside of the power generation area, the tile includes, in thickness, the plastic material of the shell,
the silicon-based plate of the photovoltaic element being hermetically encapsulated in the Ethylene Vinyl Acetate film, the electrical connection means passing through the film,
the tile upstream part, intended to be overlapped, further including, on the front face, at least one hole, and the tile downstream part further including, on the rear face, at least one tab protruding rearward, said at least one hole and at least one tab being of complementary shapes in such a way that, when the tile upstream part is overlapped by the downstream part of another tile, the tab of the other tile is engaged into the tile hole, and
wherein one of the left lateral edge and the right lateral edge of the tile includes, at a downstream part of the tile, a cut-out configured to allow the installation of a tile holding stud or hook to be fixed to a roof frame or to battens.
