[0047] The glass panel 201 is made of tempered glass and can protect the battery cells and allow light to pass through;

[0048] The silicon wafer 202 converts solar energy into electrical energy through the photovoltaic effect. The silicon wafers are connected together to form the power generation body of the battery assembly. The backplane 203 is located on the back of the silicon wafer 202 to protect the silicon wafer 202 and provide mechanical support. The backplane 203 is light-transmissive.

[0049] Particularly, in the embodiment of the present invention, the light source 204 is integrated on the back side of the back plate 203 , and the light source 204 illuminates the entire solar panel assembly 200 by reflection or direct illumination.

[0050] Specifically, the light source 204 of the present invention is an infrared light source, and the infrared light source selected is a high-power, long-life LED lamp, such as Figure 2 As shown, according to the size and shape of the solar panel assembly 200, the light sources 204 are evenly distributed on the back of the solar panel in a matrix form, wherein the multiple light sources 204 distributed in the matrix form are connected in series and connected to the positive electrode 205 and the negative electrode 206 of the assembly to realize the power supply of the light sources 204.

[0051] The light source 204 is installed in a back-to-back, back-to-face or incident angle manner to ensure that the light source can illuminate the entire solar panel by reflection or direct illumination.

[0052] Please continue to refer to Figure 1In the embodiment of the present disclosure, the solar panel with crack self-display function of the embodiment of the present disclosure also includes a detection and identification device 100 arranged on the front of the solar panel assembly 200.

The AI ​​algorithm can identify the pattern and position of the cracks, automatically mark the suspicious areas, and provide a quantitative analysis report of the cracks.

[0057] Furthermore, considering the heat that may be generated by the light source 204 when working for a long time, the present invention designs a heat dissipation structure, such as a heat sink or a heat dissipation substrate, around the light source 204 to maintain the stable operation of the light source.
