Grounding Washer

Relable Electrical Bonding for Photovoltaic Systems

The Solar PV Piercing Earthing Washer is an indispensable accessory designed to guarantee the electrical safety and grounding integrity of solar power installations. Typically installed at the intersection of solar module frames and mounting brackets, this washer creates a seamless electrical path across the entire racking structure, effectively mitigating the risk of lightning strikes, static buildup, and insulation faults.

Key Features & Benefits

Innovative Penetrating Teeth: Features a specialized toothed/ribbed structure that effortlessly pierces through oxide layers or anodized coatings on aluminum rails and module frames, ensuring an immediate and stable electrical connection.

Ultra-Low Contact Resistance: By establishing a direct, high-pressure metal-to-metal contact, it significantly minimizes electrical resistance and optimizes grounding continuity.

Premium Weatherproof Construction: Crafted from high-strength stainless steel (SUS304/SUS316) or galvanized steel, offering excellent mechanical strength and exceptional corrosion resistance for harsh, decades-long outdoor exposure.

Cost-Effective Safety: Simplifies the grounding process by eliminating the need for bulky copper grounding wires on every single panel, drastically cutting down on labor costs and material expenses.

Primary Application Scenarios

Designed to fit seamlessly into any structural racking setup, these earthing clips are essential for:

1. Commercial & Residential Rooftop Arrays: Ensuring rapid and code-compliant grounding on aluminum rail systems.

2. Utility-Scale Ground Mounts: Maintaining long-term electrical bonding across large steel or aluminum structures.

3. Solar Carports & Trackers: Providing flexible yet secure bonding points that withstand movement and continuous wind vibration.
