[0049] The testing method of the present invention can test the performance data of the photovoltaic component 9 under various scenarios:

[0050] First, a blank experiment is performed as a comparison. When performing the blank experiment, the photovoltaic component 9 is not installed in the fixing frame 4. The height and the tilt angle of the simulated light source 20 are adjusted by the lifting plate 16 and the fixing rod 19. Then, the first humidifier 6 and the second humidifier 5 are turned on at the same time to make the first test box 2 and the second test box 3 reach the same humidity condition. The humidity data is obtained by the first humidity sensor 13 and the second humidity sensor 28. Then, the simulated light source 20 is turned on to irradiate the first test box 2 and the second test box 3 until the first test box 2 and the second test box 3 reach the same temperature. The temperature data and the time data used to reach the temperature are recorded as comparison data.

[0051] Then, the photovoltaic component 9 to be tested is installed in the fixing frame 4, and the height and tilt angle of the simulated light source 20 are adjusted again to the same state as in the blank experiment. The simulated light source 20 is turned on to irradiate the photovoltaic component 9, and the irradiation time is the same as that in the blank experiment. Then, the temperature data inside the first test box 2 is measured by the first temperature sensor 11, and the temperature data inside the second test box 3 is measured by the second temperature sensor 27 to obtain the data difference between the two, and the data is compared with the temperature data of the blank experiment to obtain the performance test result of the photovoltaic component 9. When testing the photovoltaic component 9, the humidity inside the first test box 2 and the second test box 3 can be controlled under the same conditions by the first humidifier 6 and the second humidifier 5, or the humidity inside the two can be controlled under different conditions, so that the performance of the photovoltaic component 9 under the same and different humidity conditions indoors and outdoors can be obtained;

[0052] In addition, the second motor 21 can be used to control whether the gauze curtain 24 is unfolded. When the gauze curtain 24 is unfolded, the performance of the photovoltaic component 9 can be tested when there is a lot of floating dust. When the gauze curtain 24 is retracted, the performance of the photovoltaic component 9 can be tested when there is less floating dust.

[0053] When the simulated light source 20 irradiates the photovoltaic component 9, the photovoltaic component 9 can convert part of the light energy into electrical energy and store it in the battery 7. The power in the battery 7 is displayed by the power display 8. In this way, the solar energy conversion performance under the state of floating dust and the different humidity conditions on both sides of the photovoltaic component 9 can be tested.
