Structural plastic materials are normally not resistant to elevated temperatures, and accordingly presently have only limited applications in solar energy collection devices despite their decided cost advantages. The present invention enables the widespread use of such plastic materials, in fact enables the essentially complete construction of solar collection devices thereof. An optically dense radiant heat absorbable fluid is passed through the device and utilized to collect solar energy from such devices. Should such fluid not be present within the device for any reason, e.g. upon pump failure, sunlight entering is positively directed outwardly thereof. Preferably the outward direction of sunlight from the fluid receiving chamber is accomplished by providing one of the surfaces forming such chamber with a highly reflective surface so that the sun's rays are outwardly deflected. In certain embodiments, as when the device is used as an architectural window, when such fluid is not present within the device, the solar energy is directed entirely through the device. In this manner, the chamber temperature may be held within tolerable levels for the particular plastics utilized. |

DETAILED DESCRIPTION What is claimed is: 1.
A solar energy collection device operable in both active and passive modes, comprising at least one face panel and a base panel each formed of generally non solar energy absorbent plastic materials structurally distortable above a predetermined temperature level positioned in opposed spaced relationship to each other and forming a fluid chamber therebetween, said base panel defining lower portions of said chamber, said cover being at least translucent to permit entry of solar energy into said chamber, means for sensing the amount of solar energy available from said device, pump means for passing an optically dense solar heat absorbent fluid under positive pressure through said chamber wherein said fluid will absorb heat from solar energy passing into said chamber, means for removing said fluid from said chamber either when it is not desired to absorb solar energy in said fluid in the active operational mode of said device or upon failure of said pump means, said base panel also being at least translucent such that sunlight will pass directly through said panels and said chamber at those times when said optically dense fluid is removed from said chamber so as to enable said device to operate in said passive mode while simultaneously thereby maintaining the temperature of said structurally distortable panels below said predetermined temperature, said base having an upstanding peripheral edge in liquid sealing contact with portions of said cover and further having a plurality of parallel and spaced inwardly directed grooves formed therein, said cover further integrally connected and accordingly sealingly engaged with base portions between said grooves so as to form separate generally straight, non-serpentine flow paths which are capable of receiving said heat absorbent fluid under pressure from said pump means, and manifold means at each end of said individual flow paths for simultaneously directing said fluid into and out of all of said flow paths
