Abstract
It is provided a solar energy module for converting solar radiation to thermal energy. The module includes a thermally insulating element transmissive to solar radiation and having low transmissivity to thermal infra-red radiation, an absorbing element, a sealed enclosure, and a variable portion in the envelope of the sealed enclosure. This portion is adapted for varying the volume available to gas enclosed in the enclosure in accordance with changing temperature of the enclosed gas. Also, it is provided a solar energy module which includes a thermally insulating element, an absorbing surface and liquid pipes for absorbing the solar radiation, and an air duct thermally coupled thereof. The heated liquid and the heated air are usable for a variety of thermal applications. A heat storage may be thermally coupled to the absorbing surface and to the liquid pipes. The air duct has several air valves, and is associated with a controller for regulating air flow through the air duct. The controller may regulate heat flow in accordance with an optimization program, receiving inputs from several sources, like a sensor monitoring a building, a sensor monitoring the solar energy module, and an…
