Problems solved by technology

Since the photovoltaic panel tracking device only needs to rotate 80 degrees to 120 degrees in one day, the angular velocity of the rotation is very small, so the deceleration mechanism needs to have a relatively large reduction ratio; because it is difficult to achieve ultra-low uniform rotation, it is generally used for photovoltaic panels. Perform intermittent control to adjust the angle of the photovoltaic panels at intervals, so that the utilization rate of light energy is low; because of intermittent control, it is necessary to frequently start the drive motor, and the operating current of the drive motor is large when it is started instantaneously, and the instantaneous input power and The impact on the motor is large, which affects the working life of the motor, and the hardware resources of the drive system are also wasted; the motor-reduction mechanism operates in a wind, rain, sand and dust environment for a long time, and the failure rate is high

These all limit the commercial promotion and use of automatic tracking devices for photovoltaic panels
