Abstract

L'invention concerne un support de module photovoltaïque et un module photovoltaïque. Le module photovoltaïque (200) comprend un stratifié de cellules photovoltaïques (1) et un support (2) utilisé pour être fixé à une surface de montage. Le support est raccordé à l'arrière du stratifié de cellules photovoltaïques et comprend une première partie de connexion (22) et une deuxième partie de connexion (26). La première partie de connexion est proche de la face avant du stratifié de cellules photovoltaïques, et la deuxième partie de connexion est proche de la face arrière dudit stratifié. Quand de multiples modules photovoltaïques sont fixés à la surface de montage, la première partie de connexion d'un module et la deuxième partie de connexion d'un autre module adjacent sont reliées de manière à maintenir les positions relatives des modules photovoltaïques adjacents, et fixer les multiples modules photovoltaïques sur la surface de montage. Le support de module photovoltaïque et le module photovoltaïque ont des structures simples et sont pratiques à fixer et à entretenir.
