Abstract: An arrangement of photovoltaic panels is configured for installation in a greenhouse having support beams. The arrangement includes frames. Each frame comprises at least one photovoltaic panel mounted on a rod. At least one motor is mechanically connected to rotate one or more rods, for bringing each photovoltaic panel to different fixed angular positions. Fittings are arranged at a perimeter of the arrangement. Each fitting is sized and shaped to attach to at least one of the support beams, such that the arrangement is supportable exclusively by the support beams. A system includes at least one such arrangement, a controller, and a plurality of sensors. The controller is programmed to select an optimal fixed angular position for each photovoltaic panel for promoting plant growth, based on environmental and plant conditions and the sensor outputs, and to instruct each motor to rotate each rod to the selected angular position.
