1. A solar panel unit, comprising:
a rotatably supported solar panel (20); an actuator (41) which is connected to the solar panel (20) to rotate the solar panel (20); an angle detector (60) which detects an angle of the solar panel (20); and a control unit (73) which operates the actuator (41) such that the angle of the solar panel (20) detected by the angle detector (60) coincides with a command angle, wherein the command angle is an angle of the solar panel (20) determined in accordance with a direction of the sun, the solar panel unit further comprises a command angle setting unit (72) which sets the command angle every first predetermined time, and the control unit (73) performs tracking control by operating the actuator (41) such that the detected angle coincides with the command angle every time the command angle setting unit (72) sets the command angle, and performs reset control by starting operation of the actuator (41) after second predetermined time has passed since the detected angle was misaligned from the command angle in a period between the tracking controls to reset the angle of the solar panel (20). |
