ABSTRACT:
A solar energy collector apparatus and method, the apparatus including an open-top shell-like structure. A Fresnel lens system and a mirror system inside the shell structure focus and direct solar energy toward a solar energy absorber apparatus also inside the shell structure. The shell structure is mounted upon a hollow axle in a framework for rotation about its longitudinal axis. The framework supports the longitudinal axis in a position generally parallel to the axis of rotation of the earth to provide an equatorial mounting for the solar energy collector. Rotation about the longitudinal axis adapts the solar collector for following the east-west movement of the sun. The optical apparatus in the shell structure is adapted for movement to follow the north-south seasonal changes in the sun's position. The solar energy absorber apparatus is nonrotatably supported inside the shell structure by the hollow axle and heat transfer conduits pass through the hollow axle to the solar energy absorber apparatus in nonrotable relationship therewith. A photovoltaic apparatus may be included within the shell structure for converting at least a portion of the incoming solar spectrum to electrical energy. This combination of features provides higher solar efficiencies and higher temperatures in the heat transfer fluid. The method includes tracking the sun with the solar energy collector apparatus thereby maximizing the amount of solar energy collected while eliminating coupling failures in the heat transfer conduits.
