A solar heat collector designed to obtain maximum heat from sunlight rays when operational and minimum heat from sunlight rays when non-operational. The solar heat collector contains two sheets of solid material spaced and confronting each other between which a heat transfer liquid flows through a baffle arrangement so as to increase the efficiency for obtaining higher temperatures of the heat transfer liquid.

A solar heating panel comprising means in the form of a first sheet of substantially flat solid material to convert visible radiation into heat, a second sheet of substantially-flat solid material which is at least partially transparent to visible radiation and which is substantially opaque to infrared radiation through which to transfer visible radiation energy to said first sheet, means holding said sheets in confronting spaced-relation, means giving access to the space between said sheets for filling said space with a heat transfer liquid, means to guide said heat transfer liquid in a substantially laminar flow mode between said sheets, such that when said space is filled with a liquid having an index of refraction approximating the index of refraction of said second sheet substantially all visible radiation that is incident upon said panel will be transmitted therethrough to said first sheet for conversion into heat, and said liquid flowing in said laminar flow mode will thermally insulate said sheets one from the other.
