  • Patent number: 4446852
    Abstract: The present invention relates to a solar energy collector comprising a plurality of elongated heat-absorbing troughs. The elongated heat-absorbing troughs are supported in a generally parallel side-by-side terraced array, in position to retain liquid and with an end of each trough elevated relative to the other end to permit a liquid flow by gravity toward the respective lower ends thereof. The terraced array of troughs is oriented toward to the sun to permit the impingement of solar radiation upon the troughs. Heat-absorbing liquid is introduced into the troughs at the upper ends thereof to produce a flow of the heat-absorbing liquid toward the respective lower ends, with the heat-absorbing liquid becoming heated by the exposure to solar radiation. The heat-absorbing liquid is then collected from the troughs at the lower ends thereof.
