[0027] By installing the connector 1 between adjacent wall panels 5, the wall panel 5 relatively located at the lower side and the connector 1 are installed on the wall purlin 6 through the fastener 4 to fix the position of the connection node; then the photovoltaic component 3 is installed between the first slot 101 and the second slot 102 of the adjacent connector 1, and the photovoltaic component 3 is installed and fixed by plugging; it has the advantages of simple installation and no need to use installation tools; at the same time, a simple mechanical connection method is used instead of the existing adhesive bonding method, which greatly improves the safety and stability of the connection node.

[0028] Among them, the first end of the wall panel 5 is inserted into one side of the connecting piece 1, and the fastener 4 passes through the connecting piece 1 and the first end of the wall panel 5 to fix the connecting piece 1 and the wall panel 5 on the wall purlin 6; the second end of the adjacent wall panel 5 is inserted into the other side of the connecting piece 1; that is, the connecting piece 1 is located between two adjacent wall panels 5, and the wall panel 5 and the connecting piece 1 located at the lower side relatively are installed on the wall purlin 6 through the fastener 4, and the wall purlin 6 is installed on the factory building structural column 7; from the actual installation point of view, each wall panel 5 and each connecting piece 1 actually corresponds to a wall purlin 6, that is, the three are in a one-to-one fixed relationship.

[0029] Among them, the first plug-in end of the photovoltaic component 3 is plugged into the first slot 101 of the connector 1, and the second plug-in end of the photovoltaic component 3 is plugged into the second slot 102 of the adjacent connector 1; that is, the two adjacent connectors 1 are arranged one above the other along the height direction of the wall panel 5, and the notch of the second slot 102 of the connector 1 on the lower side is arranged face to face with the notch of the first slot 101 of the connector 1 on the upper side, that is, the space between the second slot 102 of the connector 1 on the lower side and the first slot 101 of the connector 1 on the upper side forms an installation space for the photovoltaic component 3, which is used to install the photovoltaic component 3. Through the plug-in installation method, tools are not required during the construction process, and the installation method is simpler and faster.

[0030] Specifically, the fastener 4 is a self-tapping screw; a self-tapping screw is a screw with sharp threads that can cut its own threads and be screwed into fixation in materials such as metal, plastic, and wood. It does not require pre-drilling or tapping, so it is very convenient to use.

[0031] In another embodiment, the notches of the first slot 101 and the second slot 102 are arranged in opposite directions, and the depth of the first slot 101 is greater than the depth of the second slot 102.

[0032] Among them, the notches of the first slot 101 and the second slot 102 are arranged in opposite directions, that is to say, the notches of the first slot 101 and the second slot 102 are arranged in different directions.

[0033] Among them, the depth of the first slot 101 is greater than the depth of the second slot 102, that is to say, when installing the photovoltaic module 3, the height of the installation space formed between the second slot 102 of the lower connecting member 1 and the first slot 101 of the upper connecting member 1 is greater than the height of the photovoltaic module 3. First, it provides sufficient operating space for installation and maintenance personnel, reducing operation difficulties and safety hazards caused by narrow space; second, the larger installation space can prevent the photovoltaic module 3 from colliding with the slot, and the sufficient space can prevent damage caused by accidental collision; third, considering the thermal expansion and contraction conditions, it improves the service life of the photovoltaic module 3.

[0034] In another embodiment, a gap is provided between the first insertion end of the photovoltaic module 3 and the bottom of the first slot of the connecting member 1, and a rubber pad 2 is provided in the gap.

[0035] Among them, the rubber pad 2 is a hard rubber pad, which is used to fix the position of the photovoltaic module 3, increase the friction at the connection between the two, and prevent the photovoltaic module 3 from moving in the slot under the action of vibration. At the same time, the rubber pad 2 also has a buffering and shock-absorbing effect.

[0036] The specific installation process is as follows:

[0037] The photovoltaic module 3 is first installed in the first slot 101. The photovoltaic module 3 relies on its own gravity and naturally slides down to fit with the bottom of the second slot 102; at this time, a gap is formed between the end face of the photovoltaic module 3 and the bottom of the first slot 101, and the rubber pad 2 is inserted into the gap to fix the position of the photovoltaic module 3.

[0038] In another embodiment, structural adhesive is applied at the connection between the rubber pad 2 and the first slot of the connecting member 1 to relatively fix the rubber pad 2 and the connecting member 1. By applying the structural adhesive, the position of the rubber pad 2 is further defined.

[0039] In another embodiment, the connecting member 1 further includes a connecting portion 103 and a wall panel plugging portion 104. One end of the wall panel plugging portion 104 is connected to the connecting portion 103, and the other end of the wall panel plugging portion 104 is connected to the photovoltaic module plugging portion.

[0040] Among them, the connecting portion 103 is in close contact with the wall panel 5 located relatively on the lower side, and then self-tapping screws are sequentially passed through the connecting portion 103 of the connecting member 1 and the wall panel 5 to fix the two on the purlin 6.

[0041] In another embodiment, the wall panel plugging portion 104 includes a first positioning groove 1041 and a second positioning groove 1042. The notch orientation of the first positioning groove 1041 is the same as that of the first slot 101, and the notch orientation of the second positioning groove 1042 is the same as that of the second slot 102.

[0042] When two wall panels 5 are installed on the connecting member 1, the wall panel 5 located on the upper side of the connecting member 1 is restricted in position by the second positioning groove 1042; the wall panel 5 located on the lower side of the connecting member 1 is restricted in position by the first positioning groove 1041; when the second end of the wall panel 5 located on the upper side of the connecting member 1 contacts the bottom of the second positioning groove 1042, it indicates that the wall panel 5 located on the upper side of the connecting member 1 is installed in place; when the first end of the wall panel 5 located on the lower side of the connecting member 1 contacts the bottom of the first positioning groove 1041, it indicates that the wall panel 5 located on the lower side of the connecting member 1 is installed in place.

[0043] In another embodiment, the first end or the second end of the wall panel 5 at the end is set to be a plane.

[0044] Among them, the first end or the second end of the wall panel 5 at the end is set to be a plane, that is to say, the first end or the second end of the wall panel 5 at the end does not need to be plugged and installed with the connecting member 1, so it is set to be a plane.

[0045] In another embodiment, the wall panel 5 is a polyurethane thermal insulation wall panel. The polyurethane thermal insulation wall panel has an extremely low thermal conductivity, far lower than that of traditional thermal insulation materials, can effectively isolate the indoor and outdoor temperature difference, and reduce energy consumption. The combustion performance of the polyurethane thermal insulation board reaches B1 level, does not melt, soften or spread flame penetration at high temperature, and fundamentally solves the occurrence of external thermal insulation fires. The polyurethane thermal insulation wall panel has a lower density and is light in weight, which is convenient for transportation and installation, and at the same time has a higher compressive strength. The polyurethane rigid foam has good waterproof performance and low water absorption rate, can effectively prevent water vapor penetration, and protect the building structure from getting damp and mildewing.

[0046] In another embodiment, the photovoltaic module 3 is a frameless photovoltaic module. The frameless photovoltaic module reduces the possibility of dust and snow accumulation, helps to keep the surface of the module clean, and thus reduces the power generation loss caused by shading. Compared with the traditional framed photovoltaic module, the frameless photovoltaic module is usually thinner and lighter, which is convenient for transportation and installation.

[0047] Through the optimization of the connection nodes, this application saves the steel keel part in the conventional metal roof photovoltaic system, reduces the material consumption and the corresponding cost; at the same time, the components can be installed on-site without tools, improving the construction efficiency, saving the time cost, and reducing the weight of the wall and roof photovoltaic system, which is beneficial to the stress of the main structure; the mechanical connection solution in this application is easier to inspect and maintain compared to the chemical connection solution; the installation scheme of the conventional wall photovoltaic system belongs to the BAPV category. Through the design of the integrated connection nodes, the BIPV design of the wall photovoltaic system can be realized, and customized and prefabricated roof BIPV products can be formed, which is beneficial to market promotion and implementation.

[0048] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0049] The above are only the preferred embodiments of this application, and are not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of this application shall be included within the protection scope of this application. The above is only the preferred implementation mode of this application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of this application, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of this application.
