DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0033] First, the infrastructure, such as Figure 1 As shown, an inward-turning frame of a photovoltaic module includes a top edge plate 101, a first side edge plate 102, a first bottom edge plate 103, a second side edge plate 104, and a second bottom edge plate 105;

[0034] The top plate 101, the upper portion of the first side plate 102, and the second bottom plate 105 form a first space with an open side, and the first space is used to place the edge of the photovoltaic panel of the photovoltaic module;

[0035] The lower portion of the first side panel 102, the first bottom panel 103, the second side panel 104, and the second bottom panel 105 form a second space, and the second space is used to place the corner bracket;

[0036] Before the corner bracket of the photovoltaic module is installed, a disconnected shape is formed between the second bottom edge plate 105 and the first side edge plate 102 so that the size of the second space can be elastically changed; after the corner bracket is installed, the second bottom edge plate 105 and the first side edge plate 102 are welded to fix the size of the second space.

[0037] In conventional photovoltaic module frames, the size of the second space for inserting corner brackets is typically fixed. In conventional existing installation methods, this second space is slightly larger than the corner bracket during manufacturing to facilitate installation. However, after installation, the gap between the corner bracket and the frame is large, which can affect the stability of the connection between one frame and the other. In the present invention, before the corner brackets of the photovoltaic module are installed, a disconnected shape is formed between the second bottom plate 105 and the first side plate 102 to allow the size of the second space to change elastically, thereby facilitating the installation of the corner brackets. After the corner brackets are installed, the second bottom plate 105 is welded to the first side plate 102 to fix the size of the second space, thereby improving the stability of the frame.

[0038] Specifically, in an optional embodiment, a portion of the second bottom edge plate 105 is recessed downward to form a pit. In the present invention, each bottom edge plate and side edge plate is not limited to be a straight plate.
