PURPOSE: A structure for installing a secondary lens in a solar condensing apparatus is provided to minimize heat generated from a solar cell by firstly discharging heat due to the condensing of a Fresnel lens using a secondary lens unit. CONSTITUTION: A secondary lens unit includes a cylindrical pipe(5a), a spherical lens(7a), a screw(9), an annular bracket(11a), and a protrusion part(13a). The spherical lens is installed in the cylindrical pipe. The screw combines the cylindrical pipe with the spherical lens. The annular bracket is spread in an outer circumference direction of the cylindrical pipe. The protrusion separates the spherical lens from the solar cell with a predetermined height. |
