[0043] Furthermore, each photovoltaic module 201 or every other photovoltaic module 201 has its four corners covered with paper corner protectors to protect the frame of the photovoltaic module 201.

[0044] Furthermore, refer to Figure 3 After the photovoltaic modules 201 are stacked and bundled, cardboard boxes 204 are placed over the stacked photovoltaic modules 201 to isolate the photovoltaic modules 201 from the fasteners 3 and protect the photovoltaic modules 201.

[0045] Fasteners 3 are wrapped around the top four corners of the photovoltaic module unit 2. Fasteners 3 have connecting ends set on the top surface of the photovoltaic module unit 2 and the adjacent side walls. The connecting ends of the two fasteners 3 located diagonally on the top surface are connected by the first packing strap 4, and the connecting ends located on the side walls are connected to the tray 1 by the second packing strap 5.

[0046] Specifically, there are four fasteners 3, which are located at the four corners of the top of the photovoltaic module unit 2. The connecting end is used to connect the fastener 3 with the first packing strap 4 and the second packing strap 5. The connecting ends of the two fasteners 3 located diagonally on the top face are connected by the first packing strap 4, so that the first packing strap 4 on the top surface of the photovoltaic module unit 2 is arranged in a cross structure.

[0047] Additionally, the guard 6 is configured to cover the side wall corners of the two single-tray assemblies placed on the stack, and the four guard 6 are fitted with a third packing strap 7 on their outer sides.
