[0019] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0020] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is inverted, an element described as being "below" another element or feature would be positioned "above" the other element or feature. Thus, the exemplary term "below" can encompass both above and below orientations.

[0022] The following is a detailed description of the present invention in conjunction with the accompanying drawings: A photovoltaic panel detection device of the present invention includes a detection box 1, a box door is hinged on the detection box 1, a rotating table 2 is provided on the back plate of the detection box 1, a support frame is connected to the rotating table 2, a tilt sensor 5 is installed on the support frame, the support frame includes an upper frame 3 and a lower frame 4, a vacuum pump 16 is installed on the lower frame 4 in a liftable manner, the vacuum pump 16 is connected to a vacuum chamber 15, the vacuum chamber 15 is connected to a suction cup 11 frame 9, A suction cup 11 is installed on the suction cup frame 9, and the suction cup 11 is connected to the vacuum chamber 15 through a pipe 14. An opening that matches the position of the suction cup 11 is provided on the upper frame 3 for the suction cup 11 to rise. Fixed pulleys 7 are provided at the four corners of the opening on the upper frame 3. The fixed pulley 7 can make it easier to put the photovoltaic panel into place. A strain gauge 17 is provided on the rotating shaft of the fixed pulley 7; a fluorescent lamp 18 is provided on the top of the detection box 1; a heater 20, a temperature sensor 19 and an ammeter 6 are provided in the detection box 1.

[0023] An electric cylinder 8 is installed on the lower frame 4 , and a piston rod of the electric cylinder 8 is connected to a vacuum pump 16 .

[0024] The four corners of the suction cup 11 frame 9 are provided with slots 10, and the suction cup 11 is provided with an air suction pipe that matches the slot 10. The air suction pipe is connected to the vacuum chamber 15 through a pipeline 14. Two nuts 13 are installed on the air suction pipe through threaded cooperation. The two nuts 13 lock the suction cup 11 at the slot 10.

[0025] The ammeter 6 is an intelligent ammeter 6 .

[0026] The detection box 1 is provided with a controller 21, which is based on a single chip microcomputer and is connected to the strain gauge 17, the temperature sensor 19, the tilt sensor 5, the heater 20, the fluorescent lamp 18, the ammeter 6, the electric cylinder 8 and the vacuum pump 16 respectively;

[0027] Preparation stage:

[0028] Ensure that the vacuum pump 16 is well connected to the vacuum chamber 15 and that there is no leakage in the pipelines 14.

[0029] Check that the temperature sensor 19, ammeter 6, strain gauge 17, inclination sensor 5 and other detection components are working properly.

[0030] Place the photovoltaic panel on the four fixed pulleys 7, control the piston rod of the electric cylinder 8 to extend to a preset height, and make the suction cup 11 push the photovoltaic panel away from the fixed pulley 7; control the vacuum pump 16 to run, under the action of the vacuum pump 16, the suction cup 11 can suck the photovoltaic panel; control the piston rod of the electric cylinder 8 to retract, when the strain gauges 17 on the four fixed pulleys 7 all detect value changes, it means that the photovoltaic panel has been stably supported by the four fixed pulleys 7, and then the electric cylinder 8 stops moving.

[0031] Lighting angle adjustment and detection:

[0032] The control starts the rotating platform 2, which can drive the support frame to rotate. The support frame can be adjusted to a desired angle according to the feedback of the inclination sensor 5.

[0033] The fluorescent lamp 18 on the top of the detection box 1 is turned on to simulate the lighting environment.

[0034] After a period of illumination, the reading of the ammeter 6 is observed, and the controller 21 can also record the current value detected by the ammeter 6.

[0035] Temperature adjustment and detection:

[0036] The heater 20 is turned on, and according to the feedback from the temperature sensor 19, the temperature in the detection box 1 is raised to a set value, for example, from a normal temperature of 25°C to 40°C.

[0037] During the temperature change process, the reading of the ammeter 6 is continuously observed, and the controller 21 can also record the current value during the temperature change process.

[0038] The impact of light angle on photovoltaic panel performance:

[0039] The temperature in the detection box 1 was set to 35°C and kept constant.

[0040] The tilt angle of the photovoltaic panel is gradually adjusted from 0° to 90° using the rotating table 2, with each 10° being a detection point.

[0041] At each angle point, after the fluorescent lamp 18 is turned on and stabilized for a period of time, the controller 21 records the current value detected by the ammeter 6. The influence of the illumination angle on the performance of the photovoltaic panel can be reflected based on all the values finally obtained.

[0042] The impact of temperature on photovoltaic panel performance:

[0043] The inclination angle of the photovoltaic panel is fixed at 45°.

[0044] Starting from 20°C, the temperature in the detection box 1 was increased in 5°C intervals until it reached 50°C.

[0045] At each temperature point, after the fluorescent lamp 18 is turned on and stabilized for a period of time, the controller 21 records the current value detected by the ammeter 6. Based on all the values finally obtained, the impact of temperature changes on the performance of the photovoltaic panel at that angle is analyzed.
