NSPV Solar earthing clamp on PV panel bracket
Product Introduction
The NSPV Solar Earthing Clamp, also referred to as a Solar Grounding Connector or Solar Earth Lug, is a critical component designed to ensure effective electrical bonding and grounding in photovoltaic (PV) mounting systems. It provides a stable, low-resistance grounding path between PV modules, aluminum mounting rails, and the system grounding conductor, ensuring compliance with international electrical safety standards.
In large-scale and distributed solar installations, reliable grounding is essential not only for personnel safety but also for long-term system stability, lightning protection, fault current dissipation, and reduction of potential-induced degradation (PID). NSPV grounding connectors are engineered specifically for harsh outdoor PV environments, where temperature fluctuations, humidity, UV exposure, and corrosion risks are constant challenges.
NSPV solar earthing clamps are widely applied in utility-scale solar power plants, commercial and industrial (C&I) rooftop systems, and residential PV installations. By combining high-conductivity materials, precision mechanical design, and standardized dimensions, NSPV ensures consistent grounding performance throughout the entire service life of the PV system.

Our Features
1 High Conductivity Materials
The grounding clamp uses copper as the primary conductive material, ensuring excellent electrical conductivity and minimal contact resistance. Stainless steel (SUS304) fasteners provide mechanical strength and corrosion resistance without compromising electrical performance.
2 Secure Mechanical Bonding
The clamp structure is engineered to penetrate anodized aluminum oxide layers on PV module frames or mounting rails, ensuring a stable metal-to-metal electrical connection. This guarantees long-term grounding reliability even under vibration, thermal cycling, and wind loads.
3 Wide Cable Compatibility
With cable compatibility ranging from 1.5 mm² up to 70 mm², NSPV grounding connectors support various system sizes—from residential rooftops to large-scale solar farms—without requiring custom grounding solutions.
4 Broad Frame Thickness Adaptability
The 0.8–4.5 mm frame thickness range allows compatibility with most standard aluminum PV module frames and mounting structures, reducing inventory complexity for EPC contractors.
5 Tool-Friendly Installation
The mechanical clamping design enables fast installation using standard tools. No special crimping equipment, welding, or surface treatment is required, improving on-site efficiency and reducing labor costs.
6 Harsh Environment Resistance
Designed for outdoor PV environments, the grounding connector maintains stable electrical and mechanical performance across a wide temperature range (-40°C to +85°C), suitable for desert, coastal, and high-altitude installations.
Our Advantages
1 Electrical Safety Assurance
A properly grounded PV system is essential for personnel safety and equipment protection. NSPV grounding connectors provide a reliable grounding path, ensuring fast fault current dissipation and compliance with international electrical safety practices.
2 Long-Term Reliability
By using corrosion-resistant materials and proven mechanical design, NSPV grounding connectors maintain stable contact resistance over time, reducing the risk of grounding failure caused by oxidation or loosening.
3 Reduced Maintenance Requirements
Once installed, the grounding clamp requires minimal inspection or maintenance, helping system owners lower long-term operational costs.
4 Standardization for EPC Projects
Multiple standardized part numbers allow EPC companies to select grounding solutions easily based on conductor size and system configuration, simplifying procurement and installation planning.
5 Compatibility with Global PV Systems
NSPV grounding connectors are suitable for PV systems designed under IEC-based standards, making them ideal for international projects across Europe, the Middle East, Africa, Asia-Pacific, and Latin America.
