Abstract

La présente invention concerne une structure de fixation d'un module de cellule solaire, des éléments de fixation (6) étant supportés à demeure sur la surface supérieure des premier et second éléments de support (4, 5), et du fait que les extrémités latérales (7a, 7b) d'une cellule solaire (7) sont verrouillées par ces éléments de sécurité (6), le travail de fixation étant réalisé depuis le flanc du module de cellule solaire (7). Etant donné que le travail de fixation est réalisé depuis le flanc du module de cellule solaire (7) même lorsque le module de cellule solaire (7) sur le côté supérieur ou le côté inférieur est fixé sur la pente (3) de la toiture, le travail est facilité et la sécurité de celui-ci peut être assurée. En outre, du fait que la surface d'extrémité avant du module de cellule solaire (7) vient buter sur la plaque de maintien (4g) contre la partie avant (4f) du premier élément de support (4), le module de cellule solaire (7) ne glisse pas et la sécurité du travail est en outre assurée.
