Abstract

La présente invention concerne un dispositif de cellules solaires qui comporte un module de cellules solaires, un organe de fixation, et une couche de revêtement qui inclut une résine. L'organe de fixation est situé au-dessus d'une section à installer. La section à installer comprend une partie de fondation, un corps de base et une partie de fixation. Le corps de base comprend une portion convexe qui fait saillie à partir d'une première surface sur le côté partie de fondation dans une première direction vers une seconde surface sur le côté opposé par rapport à la première surface et est disposée dans une seconde direction qui est orthogonale à la première direction. La partie de fixation comprend une section saillante qui pénètre dans le corps de base et fait saillie à partir de la seconde surface dans la première direction. L'organe de fixation comprend une section verticale et une section de base qui comprend une poriont qui suit la portion convexe du corps de base. La section verticale comprend : une portion de raccordement qui se raccorde à la section de base; et une portion de support qui supporte le module de cellules solaires. La couche de revêtement recouvre, de façon à enfouir, la seconde surface du corps de base, la section de base, une portion de la section saillante sur le côté seconde surface, et la portion de raccordement de la section verticale, et la couche de revêtement est fixée à la seconde surface. La partie de support fait saillie à partir de la couche de revêtement dans la première direction.
