A modular photovoltaic element for building roofs comprising: - a lower hollow structural part (4) of plastic material, - an upper convex cover element (6) of material transparent to sunlight and fixed to said hollow part, - at least one photovoltaic cell (8) mounted on a support (20) and housed in a cavity defined by said hollow part (4) and said convex cover element (6), - cabling (36, 38) associated with said photovoltaic cell (8), - provided in said hollow part (4), a compartment (32) which is separate from the cavity housing said photovoltaic cell (8), and which houses means (34) for electrical connection to the adjacent modular element of the same row, partially superposed to cover said compartment (32), - connection cables (36, 38) joined to watertight connectors (34, 30) positioned on the surmounting portions of adjacent hollow pats (4) of one and the same row, said connectors being connected to said photovoltaic cell (8) and to said integrated circuit (40), - means (24, 26) for mechanically connecting said cover element (6) to said hollow part (4), - means (42, 44) for mechanically connecting said hollow part (4) to the hollow part of adjacent elements of the same row, - a member (2) for mechanically connecting said hollow part (4) to the underlying roof structure.

L'élément photovoltaïque modulaire selon l'invention, permettant de construire des toits, comprend : - une partie structurelle creuse inférieure (4) en plastique, - un élément de couvercle convexe supérieur (6) en matériau transparent à la lumière solaire et fixé à ladite partie creuse, - au moins une cellule photovoltaïque (8) montée sur un support (20) et logée dans une cavité définie par ladite partie creuse (4) et ledit élément de couvercle convexe (6), - un câblage (36, 38) associé à ladite cellule photovoltaïque (8), - disposé dans ladite partie creuse (4), un compartiment (32) qui est séparé de la cavité logeant ladite cellule photovoltaïque (8), et qui loge des moyens (34) pour une connexion électrique à l'élément modulaire adjacent de la même rangée, particulièrement superposé pour recouvrir ledit compartiment (32), - des câbles de raccordement (36, 38) joints aux raccords étanches (34, 30) positionnés sur les parties surélevées des parties creuses adjacentes (4) d'une seule et même rangée, lesdits raccords étant connectés à ladite cellule photovoltaïque (8) et audit circuit intégré (40), - des moyens (24, 26) permettant de connecter mécaniquement ledit élément de couvercle (6) à ladite partie creuse (4), - des moyens (42, 44) permettant de connecter mécaniquement ladite partie creuse (4) à la partie creuse d'éléments adjacents de la même rangée, - un élément (2) permettant de connecter mécaniquement ladite partie creuse (4) à la structure de toit sous-jacente.
