The test device of the condensing unit module is provided. Is fixed in the vertical direction is built height adjustment rod; The fastening member is moved and fastened in the longitudinal direction of the leveling bar to adjust the focal length of the condensing unit modules in mm; Lens provided is formed extending in the one side from the retaining member; Are formed extending in the one side from the lower end is provided on the bottom surface beneath the lens and wherein the unit of condensing module fixing member units converging module fixing member fixedly coupled to the unit light-converging module of the leveling bar, the combined fixed the unit before a position of a focusing module, then, is configured to move to the left or to adjust Wu horizontal direction to adjust the focusing of sunlight focused by the lens. According to this structure, there is an effect that it is possible to find and test the distance and position with optimal power generation efficiency through the precise positioning between the adjusting the focal length between the lens and the light collecting unit of the module and the condenser module and a lens unit. In addition, simple and by a convenient mechanical construction has the effect that enables the test in the room as well as outdoors, by installing jikdal pyranometer calculating the IV curve of the solar irradiation and the cell, and to find a setup condition to obtain the optimum power generation efficiency there is an effect that it is possible.
