<p>A solar heat collecting apparatus (200) includes a first, inner glass dome (205), and a second, larger outer glass dome (210) disposed outwardly from the inner dome. Both of the inner and outer domes have respective inner and outer surfaces and an open end, and an infrared reflective coating (220) is adhered to the inner surface of the outer dome. A solder glass seal (225) joins the open ends of the inner and outer domes together, thereby forming a void (215) between said inner and outer domes. Means (305) are provided for rechargeably forming a vacuum in the void, and an absorber plate (235) is disposed beneath and covered by the inner and outer domes. Solar radiation entering the solar heat collecting apparatus according to the present invention is absorbed by the absorber plate, and transferred to a remote storage system by conventional heat transfer means, such as an array of conduits (250) placed in thermal contact with the absorber plate and containing a suitable fluid.</p> |
