Stainless Steel PV Grounding Plate for Solar Mounts FAQ

Q1: What is a stainless‑steel PV grounding plate?

A: It is a critical safety conductive accessory for solar mounting systems. It pierces the anodized coating of aluminum mounting rails and module frames, creating reliable electrical contact for equipotential bonding and system grounding, to protect the PV system against lightning surge and static electricity.

Q2: What material is it made of?

A: Made of high‑quality SUS304 stainless steel. Good corrosion resistance, suitable for coastal, saline‑alkali and other harsh outdoor environments.

Q3: How does the grounding plate work?

A: Sharp serrated teeth on the plate pierce through the insulating anodized layer of aluminum rails and module frames during bolt tightening. It establishes stable electrical connection without stripping off oxide coating manually.

Q4: Where shall we install the grounding plate?

A: Install between solar module frame and clamp, or between mounting rail and bracket. It is applicable for rooftop, ground‑mount, solar carport and BIPV PV projects. Follow local electrical codes for grounding layout.

Q5: Can multiple components share one grounding plate?

A: One grounding plate can realize electrical connection between two metal parts. For multi‑module array, you need to arrange grounding plates according to project electrical design requirements.

Q6: Does it need extra grounding wires?

A: The plate realizes equipotential bonding between mounting components. Main system grounding cable still needs to be connected to earth as per local electrical standards.

Q7: Compatible with your mid‑clamp / end‑clamp?

A: It fits most standard mid‑clamps, end‑clamps and solar rails. Please confirm rail and clamp type for special profiles.

Q8: Will it cause corrosion on aluminum parts?

A: SUS304 material matches aluminum alloy properly. Installed under correct torque value, galvanic corrosion risk is minimized under normal outdoor conditions. Do not over‑tighten the bolt.
