Sunlight angle measuring device and measuring method thereof

The invention discloses a sunlight angle measuring device and a measuring method thereof. The measuring device comprises a solar cell assembly formed by two solar cell panels, wherein angles are formed between the two solar cell panels. The solar cell panels are connected with a low-speed precision motor simultaneously. The low-speed precision motor generates different voltage difference values according to different solar cell panels; and the solar cell assembly is driven to rotate towards the optimal irradiation position. The tail end of the low-speed precision motor is connected with a rotary encoder; the rotary encoder outputs a pulse signal; and the rotation angle of the solar cell assembly is obtained by reading the pulse signal by the controller, so that the direction and angle of the optimal irradiation position of sunlight are obtained. Compared with other existing tracking systems, the sunlight angle measuring device and measuring method thereof have the following advantages:the device has a simple
