[0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. Single solar cells cannot be used directly as a power source. To use them as a power source, several single solar cells must be connected in series and parallel and tightly sealed into components. Solar panels are generally installed on the top of buildings for better lighting. They are fixed installations, but because the angle of sunlight changes, it is not possible to efficiently collect solar energy during the sunshine period. Summary of the invention

[0004] Preferably, the second motor drives the pin to rotate via a gear set or the shaft end of the second motor is fixed to the pin.

[0005] Preferably, the first motor and the second motor are stepper motors or servo motors.

[0006] Preferably, the gear ratio between the bevel gear on the outer ring of the planar bearing and the bevel gear fixed on the first motor is one of 45, 90, and 180.

[0007] Preferably, the wiring harness of the second motor passes through the interior of the bracket and is led out from the center of the plane bearing, so that when the first motor drives the plane bearing to rotate, the wiring harness will not cause the problem of wiring harness entanglement.

[0008] Preferably, the workflow of the PLC controller includes the following steps:

The PLC controller receives the light intensity signals of the eight light sensors of the direction sensing device, and compares them to determine the number of the light sensor with the strongest light, and sends a control instruction to the first motor to drive the solar panel automatic adjustment device to the direction of the light sensor; the PLC controller receives the light intensity signals of the five light sensors of the elevation sensing device, and compares them to determine the number of the light sensor with the strongest light, and sends a control instruction to the second motor to drive the solar panel automatic adjustment device to the elevation angle of the light sensor.

[0011] Preferably, the control instructions issued by the PLC controller to the first motor and the second motor are determined by subtracting the number of the light sensor with the strongest light after the jump from the number of the light sensor with the strongest light before the jump, and the difference is the number of pulse signals issued by the PLC controller to the first motor and the second motor.

[0012] Preferably, one of the pulse signals causes the plane bearing or pin to rotate 45° clockwise, and the number of rotations of the first motor is determined by the gear ratio of the bevel gear on the outer ring of the plane bearing to the bevel gear fixed to the first motor.

[0013] The present invention transmits the surfaces where the strongest light is sensed in the horizontal direction and the vertical plane to the PLC controller through the solar energy sensing control device, which controls the rotation of the first motor and the second motor, so that the solar panel can always face the plane direction and vertical elevation angle with the strongest light intensity, so that the power generation panel can be directly exposed to sunlight during the daytime period, thereby improving the power generation efficiency of the photovoltaic power generation panel and extending the power generation period, which is a significant technical advancement in this field.

[0019] More specifically, the second motor 7 drives the pin 5 to rotate via a gear set or the shaft end of the second motor 7 is fixed to the pin 5 .

[0020] More specifically, the first motor 6 and the second motor 7 are servo motors.

[0021] More specifically, the gear ratio between the bevel gear 9 on the outer ring of the plane bearing 2 and the bevel gear 10 fixed on the first motor 6 is 90.

[0022] More specifically, the wiring harness of the second motor 7 passes through the inside of the bracket 4 and is led out from the center of the plane bearing 2, so that when the first motor 6 drives the plane bearing 2 to rotate, the wiring harness will not cause the problem of wiring harness entanglement.

[0023] More specifically, the workflow of the PLC controller 11 includes the following steps:

[0024] S1. The eight light sensors 21 of the direction sensing device 12 and the five light sensors 21 of the elevation sensing device 13 are numbered clockwise;

[0025] S2. The PLC controller 11 receives the light intensity signals of the eight light sensors 21 of the direction sensing device 12, and compares them to determine the number of the light sensor 21 with the strongest light, and sends a control instruction to the first motor to drive the solar panel automatic adjusting device to turn to the direction of the light sensor 21; the PLC controller 11 receives the light intensity signals of the five light sensors 21 of the elevation sensing device 13, and compares them to determine the number of the light sensor 21 with the strongest light, and sends a control instruction to the second motor to drive the solar panel automatic adjusting device to turn to the elevation angle of the light sensor 21.

[0026] More specifically, the control instructions issued by the PLC controller 11 to the first motor and the second motor are determined based on the number of the light sensor 21 with the strongest light after the jump minus the number of the light sensor 21 with the strongest light before the jump. The difference is the number of pulse signals issued by the PLC controller 11 to the first motor and the second motor. If the difference is negative, it rotates counterclockwise.

[0027] More specifically, one of the pulse signals causes the plane bearing or pin to rotate 45° clockwise, and the number of rotations of the first motor is determined by the gear ratio of the bevel gear on the outer ring of the plane bearing to the bevel gear fixed to the first motor.
