Benefits of Vestas Shadow Detection System: • Maximise energy production while avoiding shadow flicker • Integrated into the Vestas control system • Reliable and proven technology Vestas Shadow Detection System Maximising wind turbine energy production while avoiding shadow flicker on surrounding inhabited areas Minimising negative impact on surroundings The Vestas Shadow Detection System is a solution designed to tailer turbine operation to minimise the negative impact of shadow flicker on surroundings. Shadow flicker occurs when sunlight on a certain spot is continously broken by the rotating turbine blades. Uniquely configured for each turbine, VSDS ensures maximum turbine energy production, while adhering to local requirements and avoiding shadow flicker on surrounding inhabited areas.

Example of Shadow Detection System Operation: At 5:00 PM. the shadow casted by wind turbine B reaches the nearby building. With light intensity measured to be above the established threshold, turbine B is temporarily paused to avoid the negative impact of shadow flicker. The remaining turbines in the wind farm continue to operate.
