[0039] Specifically, the photovoltaic system is composed of a number of photovoltaic components 1. To prevent lightning strikes, each photovoltaic component 1 needs to be grounded. To facilitate assembly and efficient grounding, the bottom of each panel component 12 is supported by two support bodies 11. The top surface of the support body 11 is an inclined surface, which makes the panel component 12 inclined, and each support body 11 is provided with a metal clip 3, which is used to engage the metal frame 121, and a grounding terminal 4 is provided on the metal clip 3.

Compared with the existing grounding terminal located below the metal frame of the panel component, it is easier to install the cable and the grounding efficiency is improved.

[0040] Since the metal frame 121 and the metal buckle 3 will form an oxide layer after contacting with the air, it may cause problems in the electrical connection between the metal buckle 3 and the metal frame 121, affecting the grounding conduction. To avoid the grounding conduction, refer to Figure 3 , Figure 5-Figure 7A mounting member 5 is provided at the end of the support body 11, and the mounting member 5 is provided with a defective portion 51 and a convex ridge 52.
