The rotation frame 124 includes a horizontal supporting bar 125 that is installed across the middle of the first rotation axis 122 and a vertical supporting bar 125 that is extended upwardly from end sides of the horizontal supporting bar 125. As described above, the rotation member 120 is configured that the first rotation axis 122 is installed about the X-axis on the middle of the horizontal supporting bar 125 corresponding to a center of mass of the rotation member 120 such that a horizontal balance of installment of the rotation member 120 is maintained on the supporting member 110.

  • Meanwhile, the first and second light condensing lens 135 includes a plurality of Fresno lens such that they can refract incident sunlight and irradiate it to the surface of solar cells, respectively. As a result, the sunlight, which is irradiated vertically through the light transmitting part 134 and refracted through the first and second light condensing lens 136, is incident to the surface of solar cells, and a light integration degree thereof is estimated to be 2-3 times of solar cell areas.
  • That is, the light transmitting part 134 and first and second light condensing lens 136 are configured such that sum of widths of them corresponds to 2-3 times width of the solar cell plate 132.

Here, the second angle adjustment device 150 includes a driving part 151 including an elevating member 154 that is raised upwardly or descends to downwardly by the motor 152, and a control part 156 for controlling the motor 152 of the driving part 151. At this time, the control part 156 in configured such that the changes of location of the sun depending on the diurnal motion are inputted to control automatically the motor 152. Of course, the control part 152 is configured such that the motor is driven to a real time depending on the movement of the sun using a sensor sensing the location of the sun.

Here, one end of the elevating member 154 is hinged to the module frame 137 of the light condensing module 130 and the other end thereof is connected to the motor 152.
  • For example, the driving parts 140, 150 may be driven by a hydraulic cylinder other than a motor as described in the present embodiment.
