| Summary |
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. |
| Scientific Breakthrough |
The technology on High-Concentration Photovoltaic can effectively solve sun tracking errors due to
insufficient accuracy of the sun tracking mechanical structure, land subsidence, deformation of the
mechanism, and aging, etc. |
| Industrial Applicability |
This technology is suitable for High-Concentration Photovoltaic.
Related industries include dual-axis trackers, solar tracking controllers.
This technology eliminates the need for photo sensors, and high precision sun tracking mechanism and can achieve
precise sun tracking positioning. |
