Technical Description | A sun tracking method is disclosed. The method can track the position of sun continuously by calculating a sun-tracking formula, and calibrating the mechanical structure periodically, without the need to install an optical sensor. The method comprises the steps as follows: (A) The motors of an attitude control device are driven for changing the attitude of a photovoltaic cell device according to the sun-tracking formula, and the short-circuit current of the photovoltaic cell is sensed and recorded. (B) Controlling the motor drive device to slightly adjust the attitude of the solar cell device to a position corresponding to the maximum value of the short-circuit current to maximize the power generation performance. |
