the main supporting structure 5 supports the shading material 4 to enable the shading material 4 to form a shading space in a surrounding mode, the lower portion of the shading space is open, and the shading space is used for covering the photovoltaic module to be tested so as to provide a lightless photographing environment for the EL detection camera 1;

and the EL detection camera 1 is used for shooting the photovoltaic module to be detected.

Specifically, because ordinary EL detection camera 1 is in order to carry out effectual EL detection to the photovoltaic module that awaits measuring, need operate in the environment of shading, therefore, through main bearing structure 5 and shading material 4 that can the shading, establish a shading environment of shading promptly, thereby for EL detection camera 1 provides the operational environment daytime, through hiding photovoltaic module EL detection device on the photovoltaic module that awaits measuring, thereby appear the shade area that satisfies EL detection camera 1 operating condition in the photovoltaic module top that awaits measuring, make EL detection camera 1 in the shading space equally can normally work, thereby realize utilizing ordinary EL detection camera 1 that needs to operate in the shade environment to detect the photovoltaic module that awaits measuring daytime.

Specifically, the main supporting structure 5 supports the light-shielding material 4 by a structure to form a light-shielding space, and the light-shielding material 4 can be covered on the main supporting structure 5, for example, in a form similar to an umbrella, or the light-shielding material 4 is located under the main supporting structure 5, and the light-shielding material 4 is pulled up by the main supporting structure 5, or the light-shielding material 4 is connected with the main supporting structure 5 through various fixing manners such as the supporting structure, so that the main supporting structure 5 can support the light-shielding material 4 to form a light-shielding space; on the other hand, the main supporting structure 5 needs to support the EL detection camera 1, fix the EL detection camera 1, and provide a shooting platform, so that the EL detection camera 1 can stably operate to shoot the photovoltaic module to be detected below the EL detection camera 1, the main supporting structure 5 can provide an independent supporting frame 51 of the EL detection camera 1 to support the EL detection camera 1, the supporting frame 51 can be installed at the top of the whole EL detection device for the photovoltaic module to be detected and located at the center, and can also be installed at other positions, only the requirement that the EL detection camera 1 can be aligned to the photovoltaic module to be detected to effectively shoot is met, the specific installation position of the EL detection camera 1 is not limited, meanwhile, the EL detection camera 1 may have an area which needs to work in a dark environment, and an area which can work in a non-dark environment, therefore, the EL detection camera 1 does not necessarily need to be completely placed in a shading space, only the area which needs to work in the dark environment needs to be submerged in the shading space is needed, and the remaining area can be placed outside the shading space.

It can be understood that, the photovoltaic module EL detection device of this application covers on the photovoltaic module that awaits measuring at the during operation, and shading space and the photovoltaic module that awaits measuring are airtight as far as possible to the dark environment that satisfies EL detection camera 1 operating condition is found, can change the detection position to the photovoltaic module that awaits measuring or change the subassembly through removing photovoltaic module EL detection device, and shading material 4 can not shelter from EL detection camera 1 camera lens, ensures that EL detection camera 1 can normally work.
