Abstract
A thermal collector of solar energy that is adapted for installation in the roof structure of a building includes a cover plate to transmit sunlight, a backing, and an energy-absorbing material carried by the backing, to absorb energy of the transmitted sunlight and to transfer heat of such absorbed energy to the backing. A heat transfer medium delivers heat from the backing to a heat using apparatus such as a building heating or air conditioning system or a heat pump. The backing is designed to limit the weight of the collector and to improve its rate of thermal response upon reappearance of the sunlight. For purposes of limiting heat losses from the backing to the cover plate, the collector is evacuated and components that connect the backing with the cover plate are designed for low heat flow. Thus heat is delivered to the heat using apparatus at an elevated temperature of the heat transfer medium for improved efficiency of such apparatus.
