A shade house adapted to form an adjustable shadow on a surface, in particular a planted surface, the shade house comprising: - at least one frame extending in a longitudinal direction, - a first set of photovoltaic panels mounted on the frame substantially orthogonal to a same orientation axis, fixed relative to each other, and distributed successively along the longitudinal direction, - a second set of opaque panels, preferably photovoltaic, mounted on the frame substantially orthogonal to the steering shaft, fixed to each other, and distributed successively in the longitudinal direction, the second set being movable in translation longitudinally relative to the frame at least between an open configuration of the shade house, wherein the panels of the second set are at least partially, and preferably completely, superposed on the panels of the first set when viewed along the orientation axis, and a closed configuration of the shade house, wherein the panels of the second set protrude at least partially, and preferably completely, beyond the panels of the first set when viewed along the orientation axis, - optionally, a third set of opaque panels, preferably photovoltaic, mounted on the frame substantially orthogonal to the orientation axis, fixed to each other, and distributed successively in the longitudinal direction, the third set being movable in translation longitudinally relative to the frame at least between the open configuration, wherein the panels of the third set are at least partially, and preferably completely, superposed on the panels of the first set when viewed along the orientation axis, and the closed configuration, wherein the panels of the third set protrude at least partially, and preferably completely, from the panels of the first set and the panels of the second set when viewed along the orientation axis, and - an actuation system configured to actuate the second set, and optionally the third set, at least from the open configuration to the closed configuration, and vice versa, the actuation system comprising a plurality of pulleys (74, 76, 78, 80) mounted on the frame. - at least one frame extending in a longitudinal direction, - a first set of photovoltaic panels mounted on the frame substantially orthogonal to a same orientation axis, fixed relative to each other, and distributed successively along the longitudinal direction, - a second set of opaque panels, preferably photovoltaic, mounted on the frame substantially orthogonal to the steering shaft, fixed to each other, and distributed successively in the longitudinal direction, the second set being movable in translation longitudinally relative to the frame at least between an open configuration of the shade house, wherein the panels of the second set are at least partially, and preferably completely, superposed on the panels of the first set when viewed along the orientation axis, and a closed configuration of the shade house, wherein the panels of the second set protrude at least partially, and preferably completely, beyond the panels of the first set when viewed along the orientation axis, - optionally, a third set of opaque panels, preferably photovoltaic, mounted on the frame substantially orthogonal to the orientation axis, fixed to each other, and distributed successively in the longitudinal direction, the third set being movable in translation longitudinally relative to the frame at least between the open configuration, wherein the panels of the third set are at least partially, and preferably completely, superposed on the panels of the first set when viewed along the orientation axis, and the closed configuration, wherein the panels of the third set protrude at least partially, and preferably completely, from the panels of the first set and the panels of the second set when viewed along the orientation axis, and - an actuation system configured to actuate the second set, and optionally the third set, at least from the open configuration to the closed configuration, and vice versa, the actuation system comprising a plurality of pulleys (74, 76, 78, 80) mounted on the frame.
