Only by setting the installation direction in a reverse flipping state during installation can the corresponding fixed clamping effect be achieved.

[0057] In this embodiment, by arranging a plurality of component clamping parts 81 on the back surface of the photovoltaic module 8 (i.e., the bottom surface of the honeycomb reinforced plate 4), and at the same time arranging a plurality of base surface clamping parts 91 on the vertical installation base surface 9, during installation in this embodiment, only by fixedly clamping each component clamping part 81 with its corresponding base surface clamping part 91 can the convenient installation of the photovoltaic module 8 on the installation base surface 9 be achieved, and the installation structure is simple and very easy to install and implement.

[0058] It is apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Accordingly, all changes that fall within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.

[0059] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
