Abstract

L'invention concerne un dispositif de support et/ou de fixation de cellules solaires (2) au-dessus d'une surface d'installation (6) ou sur cette dernière, comprenant un support (3, 10) constitué d'une seule pièce, produit par formage d'un matériau plat, par exemple une tôle, formant au moins un appui (8) par rapport à la surface d'installation (6) et, entre ses deux extrémités, au moins deux logements (4) pour des cellules solaires (2), situés l'un derrière l'autre et séparés par un élément de liaison (5), les logements (4) en particulier étant au moins partiellement inclinés dans le sens longitudinal par rapport à la surface d'installation (6). L'objectif de l'invention est de créer des conditions avantageuses pour la manipulation de ce dispositif. À cet effet, les cellules solaires (2) sont placées en particulier sur le support (3, 10) et les extrémités (7, 9) de ce dernier, qui s'étend sensiblement sous les cellules solaires (2), forment les appuis (8, 11).
