Device and method for solar-tracking according to sensor

摘要

The invention discloses a device and method for solar-tracking according to sensor. The device calculates the angle of incidence and azimuth of the sunray through the illuminance sensed by the sensors in different positions. The device rotates the solar panel to the direction with the maximal solar irradiation. Then the solar panel can sense the maximum illuminance to have the maximal energy gain.
