Abstract: The invention relates to a system (10) for managing an agricultural open space (12), having: at least two guide rail arrangements (11) running parallel to one another; a processing device (24) supported on both guide rail arrangements (22) and being able to be moved along the guide rail arrangements (22); at least one solar panel arrangement (28) arranged above the guide rail arrangements (22) and the processing device (24).

Abstract: The invention relates to a support structure (4) for a stationary photovoltaic system (1), comprising a support part (30) which comprises securing points for a flat photovoltaic unit (2) and at least one drive device (31) for the driven adjustment of the support part (30) and at least one single-axis adjusting device (32) which can adjust a photovoltaic unit (2), secured to the support part (30), in azimuth (a) and elevation (h) about an adjustable axis (V1) between a setup position (35) and an end position (36). The projection of the surface normals (n) of the photovoltaic-unit (2) on the horizontal plane in the setup position (35) defines a setup axis (E) and the projection of the adjusting axis (V1) on the horizontal plane defines a projected adjusting axis (P1), the projected adjusting axis (P1) to the setup axis (E) forming an angle (EP1) in the region of more than 5 degrees and less than 80 degrees, preferably in the region of more than 10 degrees and less than 60 degrees.
