Sunner's Predictive System Prevents Solar Tracker Galloping Damage

⚡ AI Executive Summary

Spanish engineering firm Sunner has developed True Wind, a predictive monitoring system that identifies aeroelastic instabilities in solar trackers before they escalate into damaging galloping events. The technology uses structural sensors and physics-based algorithms to assess tracker behavior in real time, earning recognition at Intersolar Europe's 2026 awards. Rather than relying on fixed wind-speed thresholds that trigger protective shutdowns, True Wind monitors the actual dynamic response of tracker structures, enabling more targeted intervention. This approach has meaningful implications for large-scale solar operations: by reducing unnecessary stow cycles, operators can improve capacity factors while extending equipment life through lower mechanical fatigue. The distinction between generic weather-based protection and structure-specific monitoring represents a broader industry shift toward data-driven asset management in renewable energy plants, where the ability to distinguish between safe operation and genuine risk can translate to substantial economic and operational gains.
