Development of Smart Fastener Technology in PV Mounting Systems

With the rapid development of Internet of Things (IoT) and smart sensing technologies, smart fasteners are becoming an important innovation direction for photovoltaic (PV) mounting systems. These sensor-integrated fasteners can monitor key parameters in real-time, providing data support for intelligent operation and maintenance of PV systems.

Core Functions of Smart Fasteners

• Stress Monitoring: Real-time monitoring of preload force changes to warn of loosening risks
• Temperature Monitoring: Monitoring connection point temperature to prevent overheating failures
• Vibration Monitoring: Detecting abnormal vibrations to identify structural safety hazards
• Corrosion Monitoring: Monitoring corrosion process through electrochemical sensors
• Position Tracking: GPS/Beidou positioning for asset management

Technical Implementation Solutions

Smart fasteners use miniaturized design, integrating sensors, wireless communication modules, and energy harvesting systems inside standard fasteners:

Industry Application Cases

1. Large Ground-Mounted Power Plants: Deploying 5,000 smart fasteners for real-time monitoring of entire station connection status
2. Offshore PV Platforms: Monitoring salt fog corrosion process to predict maintenance cycles
3. Distributed Rooftop Systems: Remote diagnosis of connection issues to reduce O
