A device for shading areas, in particular for shading areas or plazas where people can walk, in desert areas, comprising a roofing surface which extends on carrier elements at a spacing from the surface to be shaded, preferably with a roof skin or membrane stretched on supports, to provide for shading of larger spaces with a minimum amount of obstruction by the supports, while at the same time using the effect of sunlight which is absorbed in producing the shade. For that purpose the outward side (31) of the roofing surface (12, 21) is occupied with photovoltaic elements (30) or is provided with a photovoltaic layer. The latter preferably comprises amorphous silicon or cadmium derivatives.
