Product Introduction
1. Grounding Washer / Bonding Clip
System Function & Principle
The Grounding Washer / Bonding Clip serves as the primary electrical interface component in solar array grounding systems. Installed at the mechanical clamping points, its engineered multi-directional grounding spikes cut through top coatings (anodized aluminum or painted surfaces) under bolted compression, establishing gas-tight, low-resistance electrical pathways across the structural frame.

2. Product Features & Technical Highlights
- Precision Mechanical Spikes: Engineered 4-corner / multi-point contact geometry maximizes surface penetration pressure for ultra-low resistance.
- Galvanic Compatibility: Manufactured from passivated SUS304 (A2-70) stainless steel, preventing galvanic cell formation between steel hardware and AL6005-T5 aluminum rails.
- Vibration Resistance: Functions as a spring washer under tension, preventing bolt loosening caused by thermal expansion, contraction, and wind-induced dynamic loads.
- Streamlined Inventory: Standardized dimensions fit M8 bolts and universal rail channels across rooftop, ground-mount, and carport structures.
- Safety Certification: Fully tested to pass UL 467 grounding standard requirements and IEC 61730 safety qualifications.
