A shading system includes a housing extending along a longitudinal housing direction; a plurality of shading blades extending along a longitudinal blade direction; a coupling system comprising: a first rail; and a second rail. Each of the shading blades is rotatably coupled to the first rail and to the second rail. A coupling element is rotatably coupled to the housing and rotatably coupled to the second rail. An actuator to translate the first rail along the longitudinal housing direction. The coupling element rotates the shading blades by limiting a translation of the second rail. A rain gutter extends along the longitudinal housing direction below the plurality of shading blades.
