In the solar cell apparatus 10 according to the present invention, when the sun rises in the east, the rotation means 40 is driven to rotate the subframe to correspond to the sun. Therefore, since the photovoltaic module 100 installed in the subframe 31 corresponds to the sun, the solar power module 100 may be irradiated with sunlight as much as possible and may receive a large amount of light from the sun.

In this state, as the time passes, the sun moves along the ecliptic, and the azimuth is changed. The azimuth and the azimuth of the solar light module are recognized by a sensor (not shown). The two actuators 43 are driven to rotate the subframes 31 at a predetermined angle.
