The present invention relates to a sun tracking apparatus using a power difference of a solar cell consisting of a horizontally rotating portion and the fixed and rotating vertically.
Vertical rotary part comprises two solar tracking for generating electricity for tracking a pair of certain symmetry sun in the vertical direction and the sun tracking unit and a horizontal direction is configured as a solar cell with an angle for generating electricity to track the sun portion and is constituted by operation in the sun, which can be attached to the solar battery and the positive lens used for the heating device, a Fresnel lens for the light generation is to track the sun in the vertical direction.
Horizontally rotating unit is mounted to the vertical direction is the vertical direction and rotating the rotary motor portion mounted to track the sun in the horizontal direction.
Mounted horizontally rotating portion is equipped with a vertical rotating unit is arranged stably on the fixing part when the part is mounted horizontally rotating motor.
Be two positive terminal of the solar cell and the negative terminal constituting the solar tracking is cross-connected to the motor, when exactly solar tracking portion facing the sun If the point the exact sun tracking additional solar power is not generated for driving the motor Since the difference between the forward and reverse power generated in the two solar cell vitality a solar tracking apparatus using a principle that an electric motor for driving the generation.
Therefore, according to the present invention, it is possible to track the sun without the need for a separate control device and the program there is no consumption of electric power for driving the production is possible, and the control device and the program at a low cost compared to conventional solar tracking apparatus is economical.
In addition, since the number of parts in a convenient and to the devices difficult to attach the separate tracking devices are also small ever significantly reduced probability of failure.
