The greenhouse (1) has bays (2a-2c), where each bay includes solar panels (23) and a roof (21) having a plane surface (22) on which the solar panels are placed. The roof is configured such that luminosity at the level of a ground shade of the plane surface for illumination along a normal of the plane surface is homogenous. The ground shades of the surfaces of the roofs are joined for illumination of the greenhouse. The normal forms an angle (alpha) less than 10 degrees relative to an optimal orientation of the panels for geographical localization of the greenhouse.
