In order to connect the connecting portion 41 of the support frame 4 to the frame 2 of the photovoltaic panel 1, the frame 2 and the connecting portion 41 are respectively connected by the connecting member 3.

[0045] It should be noted that, in this embodiment, the frame 2 is used to protect the periphery of the photovoltaic panel 1, and to protect the corners at the back of the photovoltaic panel 1. Figure 1 , Figure 2 and Figure 4 As shown, the portion of the first frame 21 protruding from the back of the photovoltaic panel 1 is a first protruding portion 211 , and the portion of the second frame 22 protruding from the back of the photovoltaic panel 1 is a second protruding portion 221 .

[0046] Furthermore, in this embodiment, in order to facilitate the connection between the connector 3 and the frame 2 and to stabilize the connection between the connector 3 and the frame 2, a connection surface that facilitates the connection between the connector 3 and the frame 2 is provided on the first protrusion 211 and the second protrusion 221, for example: Figure 1 and Figure 2 As shown, the first protrusion 211 has a first connecting surface 2111 on the same side as the back side of the photovoltaic panel 1, the second protrusion 221 has a second connecting surface 2211 on the same side as the back side of the photovoltaic panel 1, and the first connecting surface 2111 and the second connecting surface 2211 are located in the same plane; and the connecting member 3 has a third connecting surface, and the third connecting surface is used to fit with the first connecting surface 2111 and the second connecting surface 2211 respectively.

[0047] It should be noted that, in this embodiment, the connection between the connecting member 3 and the frame 2 includes but is not limited to the following methods:
