Abstract

The present invention relates to a device and method for utilization of solar radiant energy employing transparent passageway and heat transfer fluid with definite coefficient of absorptivity and a hydraulic system using thereabove. The device of this invention is a flat panel comprises a base member, extruded from transparent rigid material, two collectors imperviously attached to the both opposite transverse ends of the base member and four lids arranged to close imperviously the openings of the collectors. The method of utilizing solar energy used in this invention is held by absorbing solar radiant energy directly in heat transfer fluid which coefficient of absorptivity is exactly definite. Such kind of heat transfer fluid can be a solution, colloidal solution or suspension of carbonblack and non frozen fluid as ethylene-glycol, or water based fluid.
