[0038] In this embodiment, the light receiving surface of the light receiving device 3 is flush with the side surface 2, which can ensure that the light reaches the light receiving device 3 at a predetermined angle and path, avoids measurement errors caused by physical offset, improves the accuracy and reliability of angle measurement, and reduces reflection and scattering of light before entering the light receiving device 3, ensuring that more light is directly captured and converted into electrical signals, thereby improving the efficiency of conversion from optical signals to electrical signals; the use of a unified connecting groove 5 facilitates mass production and reduces manufacturing costs; the snap-fitting of the light receiving device 3 with the connecting groove 5 facilitates rapid replacement of the light receiving device 3, simplifies the alignment and calibration steps during installation, and the connecting groove 5 provides additional physical support for the light receiving device 3, reduces displacement caused by vibration or collision during operation, thereby ensuring long-term and stable working performance of the sensor; at the same time, the snap-fitting of the light receiving device 3 with the connecting groove 5 facilitates replacement of the light receiving device 3 when the light receiving device 3 is damaged or according to test needs, thereby reducing the maintenance cost of the sensor and extending the service life of the sensor.

[0039] Furthermore, the connecting groove 5 includes a first groove body and a second groove body, the first groove body is arranged close to the top surface 1, the light receiving device 3 is clamped in the first groove body, the width of the second groove body is greater than the width of the first groove body, one end of the second groove body is connected to the first groove body, and the other end of the second groove body is arranged at the bottom edge of the side surface 2.

[0045] Specifically, in the above embodiment, the side surface 2 is a hexagon.

[0046] In this embodiment, if Figure 4As shown, under normal conditions, the side faces 2 of a regular triangular prism are all trapezoidal, while the side faces 2 of the regular triangular prism optical angle sensor provided in the present application are hexagonal. The two bottom corners of the trapezoidal side faces 2 of the traditional regular triangular prism are cut. During use, the optical angle sensor still relies on the bottom edge of the side faces 2 for support. Under the premise of ensuring the stability of the overall structure, the hexagonal structural design of the side faces 2 reduces the overall weight, improves the space utilization rate, and realizes the lightweight design of the sensor.

[0047] Specifically, in the above embodiment, the light receiving device 3 is used to receive optical signals in the 430nm-1090nm band.

[0054] In this embodiment, multiple optical angle sensors are evenly distributed on the solar panel body to ensure comprehensive monitoring of sunlight from all angles, which is convenient for timely adjustment of the angle of the solar panel to maintain optimal light reception. Multiple optical angle sensors can be used to cross-verify the sun's position data, and by comparing and fusing information from different sensors, the accuracy and reliability of angle measurement can be improved, thereby more accurately tracking the movement of the sun. Setting up multiple optical angle sensors is fault-tolerant, and even if individual sensors fail or are blocked, the remaining sensors can continue to provide valid data to ensure the normal operation of the solar panel. In addition, multiple optical angle sensors collect data simultaneously, so that the solar panel system can obtain updated light angle information more quickly, thereby making quick adjustments and improving the dynamic response capability of the system.
