Abstract

L'invention concerne un élément de liaison pour des modules de cellules solaires, réalisé sous la forme d'un élément profilé avec une première branche de profilé, une deuxième branche de profilé parallèle à la première branche de profilé et espacée de celle-ci de la largeur de la première branche de profilé, une base de profilé qui relie la première et la deuxième branche de profilé à l'une de leurs extrémités, laquelle base de profilé présente un premier prolongement qui s'étend sur le côté de la deuxième branche de profilé qui est à l'opposé de la première branche de profilé, et un deuxième prolongement formé sur la deuxième extrémité de la deuxième branche de profilé, lequel s'étend dans la même direction que le premier prolongement à une distance de celui-ci qui correspond à l'épaisseur d'un support de module. Selon l'invention, il existe à chaque fois sur la surface libre de la base de profilé et du deuxième prolongement un creux avec une contre-dépouille pour venir en prise par engagement géométrique avec une pièce profilée extérieure.
