Arrangement of photovoltaic panels and system for optimizing angular positioning of photovoltaic panels in a greenhouse

A system for optimizing angular positioning of photovoltaic panels in a greenhouse, comprising:

• at least one arrangement having a plurality of photovoltaic panels and configured for installation in a greenhouse having a roof supported by a plurality of support beams, comprising:
• a plurality of frames, wherein each frame comprises at least one rod and at least one photovoltaic panel mounted on a respective one of the at least one rod;
• at least one motor, each respective motor mechanically connected to rotate one or more respective rods, for bringing each photovoltaic panel to a plurality of different fixed angular positions;
• and
• a plurality of fittings arranged at a perimeter of the arrangement, each fitting sized and shaped to attach to at least one of the plurality of support beams, such that the arrangement is supportable exclusively by the plurality of support beams, the plurality of fittings comprising telescopic rods adjustable to different lengths and connectors attached to the telescopic rods and configured each to be located at and fitted around each of the at least one of the plurality of support beams,
• a controller;
• and
• a plurality of sensors, each of the plurality of sensors configured to monitor at least one of air temperature, leaf temperature, root temperature, irradiance, humidity, and carbon dioxide concentration at locations within the greenhouse and generate sensor outputs, and to provide the sensor outputs to the controller;
• wherein the controller is programmed to select an optimal fixed angular position for each photovoltaic panel for promoting plant growth, based on a combination of environmental and plant conditions and the sensor outputs, and to instruct each respective motor to rotate each one or more respective rods to the selected fixed angular position,
• wherein the environmental and plant conditions comprise at least one member selected from the group consisting of:
• an opacity of the photovoltaic panels;
• a range of frequencies of light transmitted through the photovoltaic panels;
• a current date;
• a current time of day;
• a type of crop that is being grown;
• a date of planting of said crop;
• a geographic location of the greenhouse;
• a shape of the greenhouse;
• a material of a cover of the greenhouse;
• and a transmittance of the cover of the greenhouse.
