Each rib has a first face arranged obliquely relative to the upper side of the lamella and adapted to be irradiated by the sun in an approximately vertical direction, and a second face which is arranged flush and at an acute angle of roughly 45° relative to the first flat element. The third face is approximately orthogonal to the second faces.
