[0027] It should be noted that the decorative plate 10 can be a ceramic tile arranged on a wall, or a curtain wall structure of a building.

[0028] It should be noted that the decorative plate 10 can be a ceramic tile arranged on a wall, or a curtain wall structure of a building. ​

[0029] Furthermore, to facilitate the installation and removal of the decorative panel 10, the first connector 30 and the second connector 40 are snapped together.

[0030] In Embodiment 1 (not shown), the first connector 30 is a snap-fit ​​or hook, and the second connector 40 is a hook or snap-fit ​​that matches the first connector 30. By setting snap-fits and hooks, the snap-fits and slots can be matched to form a snap-fit ​​structure, making installation and disassembly very convenient.

[0031] In addition, the first connector 30 and the second connector 40 can also be connected by other detachable methods, such as magnetic connection.

[0032] like Figure 2 In the second embodiment shown, the first connector 30 is conductive and is connected to the electrodes of the photovoltaic module 20; the second connector 40 includes a busbar 41, and while the first connector 30 and the second connector 40 are engaged, the first connector 30 is connected to the busbar 41.

[0033] It should be noted that the first connector 30 can be conductive in two ways: entirely or partially. Specifically, the first connector 30 can be entirely made of a conductive material, such as copper or iron, which provides both good conductivity and structural strength, reducing power loss and ensuring reliable connection. Alternatively, the first connector 30 can be partially conductive. For example, it could be a plastic structure with an electrode-like structure at the contact point between the plastic structure and the busbar 41. This electrode can be connected to the electrodes of the photovoltaic module via a wire. The electrode in contact with the busbar 41 can be made of metal or graphite. The advantage of this approach is that plastic structures are cheaper and lighter.

The two clamping arms are further provided with a guide part 33, when installing, the guide part 33 is pressed against the busbar 41, under the interaction of the guide part 33 and the busbar 41, the two clamping arms are opened, the busbar 41 enters the clamping space, and the two clamping arms are engaged on the busbar, so as to be fixed, which is convenient for installation. When disassembling, it is only needed to suck the decorative plate 10 outward by the suction cup 60 and then separate.

[0035] As shown, Figure 4 The decorative plate 10 is provided with a sealing gasket 50, which is located at the electrode connection position of the first connecting piece 30 and the photovoltaic module 20, so as to prevent short circuit caused by moisture.

By arranging the encapsulation body 42 and encapsulating the busbar 41 in the encapsulation body 42, the busbar 41 can be protected, so as to prevent damage of the busbar 41, the encapsulation body 42 can be a wiring box or encapsulation glue, before installing the decorative plate 10, a fixing groove is formed on the wall, the encapsulation body 42 and the busbar 41 are fixed in the fixing groove to complete wiring. By arranging the mounting groove 421, the busbar 41 can be partially exposed, so as to be fixed and in conduction with the first connecting piece 30. By arranging multiple mounting grooves 421, several decorative plates 10 can be connected on the busbar 41 through the metal buckles to complete electrical series connection, and the busbar terminal is connected into the overall system of the photovoltaic combiner box, the inverter, the controller, the load and the like.

[0037] It should be noted that the busbar 41 includes a positive busbar and a negative busbar, and the metal buckle also includes two, one of which is a positive metal buckle connected with the positive busbar, and the other of which is a negative metal buckle connected with the negative busbar, the positive metal buckle is in conduction with the positive electrode of the photovoltaic module, and the negative metal buckle is in conduction with the negative electrode of the photovoltaic module.
