Sturdy, UV-resistant retaining profiles can be screwed onto all solar modules with an all-round aluminum frame. They ensure optimum ventilation, a secure hold and are attached to vehicle roofs with the adhesive set without drilling. Either universally as corner profiles for one module or with a connecting profile for several modules next to or behind each other. The spoiler profiles are also visually appealing. They are attached to the module at the front and rear and thus adapt aerodynamically to the vehicle roof. The spoiler sets always include two longitudinal profiles.
