摘要： The present teachings relate to a solar roof forming element for forming a solar roof of a building, comprising an extruded, elongate polymer roof plate, element coupling means, at least one solar panel covering the roof plate, panel coupling means for coupling the solar panel to the roof plate, comprising a first coupling part at a first side of the roof plate and a second coupling part at a first side of the solar panel, said coupling parts configured such that they mutually couple as a result of a movement of the solar panel relative to the roof plate, wherein in a coupled state a movement of the solar panel away from the roof plate in a direction perpendicular to the roof plate is blocked. The present teachings further relate to a combination of such solar roof forming elements, to a building, and to a method of forming a roof.
