Under the circumstance that the anti-falling strip 200 is adhered to the corner protection structures 100 of the photovoltaic modules 300, even if the positions of the photovoltaic modules 300 are changed due to external force in scenes such as road surface jolting, the photovoltaic modules 300 can still be reliably connected together under the constraint action of the paperboard layer 20, the phenomenon of inclination or overturning is not easy to occur, and the transportation safety of the photovoltaic modules 300 is further improved.

In some alternative embodiments of the application, the cardboard layer 20 is provided with a plurality of folds 23 spaced apart along the length direction, and the extending direction of the folds 23 is parallel to the width direction of the cardboard layer 20; the gap between two adjacent folds 23 is adapted to the thickness of the photovoltaic module 300, and the larger the thickness of the photovoltaic module 300, the larger the gap between two adjacent folds 23.

As shown in fig. 6, the positions of the folds 23 may be aligned with the gaps between the photovoltaic modules 300, the number of folds 23 may be one less than the number of the photovoltaic modules 300, and the folds 23 may be used to position the photovoltaic modules 300.

Referring to fig. 7, a connection structure diagram of the corner guard structure and the anti-toppling strip in the case where the photovoltaic module needs to be peeled off is shown, and referring to fig. 8, an enlarged schematic view of the position B in fig. 7 is shown. As shown in fig. 7 and 8, in the process of peeling the photovoltaic module 300, the falling prevention strip 200 may be torn along the crease 23 of the falling prevention strip 200 to achieve accurate peeling of the photovoltaic module 300. In this way, the phenomenon that the photovoltaic module 300 which does not need to be peeled off is toppled due to low tearing precision of the anti-falling strip 200 in the peeling process of the photovoltaic module 300 can be avoided, and the peeling safety of the photovoltaic module 300 is improved, so that the use safety of the photovoltaic module 300 is further improved.

For example, in the case that only one photovoltaic module 300 needs to be peeled off, the anti-falling strip 200 corresponding to the photovoltaic module 300 may be torn off along the crease 23 of the anti-falling strip 200, so as to release the connection between the anti-falling strip 200 and the corner protection structure 100 of the photovoltaic module 300, and facilitate the removal of the photovoltaic module 300 from the tray. Thus, the rest photovoltaic modules 300 without stripping can be connected into a whole under the constraint action of the anti-falling strip 200, so that the phenomenon that the photovoltaic modules 300 without stripping fall down is avoided, and the stripping safety of the photovoltaic modules 300 is improved.

Specifically, the paperboard layer 20 may be a cardboard, a corrugated board, or the like, and the gram weight of the paperboard layer 20 is greater than or equal to 200g/m ², so that the burst strength of the paperboard layer 20 under a strong tensile force is satisfied. The cardboard layer 20 may be machined with segmented transverse lines depending on the width of the photovoltaic module 300 to facilitate later disassembly operations. The adhesive layer 21 is a double sided adhesive, the lower adhesive side 212 is adhered to the cardboard layer 20, and the upper adhesive side 211 is adhered to the gummed paper layer 22. When in use, the gummed paper layer 22 is torn off and stuck at the position of the corner protection structure 100 of the photovoltaic module 300, and the separation of the photovoltaic module 300 can be realized.
