The accessories used in installing solar brackets – the grounding clips for PV, the role of the protrusions and punctures on its surface.
The grounding clips for PV used in the installation of solar brackets have the following functions:
- Increase contact area and stability: The protrusions on the surface of the solar grounding clips can increase the contact area with the battery assembly, thereby improving the stability and reliability of the connection and ensuring smooth conduction of current.
- Puncture the oxide layer: A layer of oxide usually forms on the surface of metals such as aluminum. The presence of this oxide layer increases the contact resistance and affects the conduction of current. The protrusions of the solar grounding clips directly contact the metal substrate by puncturing this oxide layer, thereby reducing the contact resistance and improving the conductivity.
- Prevent loosening and displacement: The protrusion and puncture design can also play a role in mechanical fixation, preventing the solar grounding clips from loosening or shifting due to thermal expansion and contraction or external vibration during long-term use, ensuring the long-term stability of the electrical connection.
- Optimize conductive performance: Through the puncture mentioned above and close contact, the solar grounding clips can conduct current more effectively, reduce energy loss, and improve the overall efficiency of the solar system.
These design features enable the grounding clips for PV to not only provide reliable mechanical connection during the installation of the solar rack but also optimize electrical performance and improve the overall efficiency and reliability of the solar system.
