Shadow Flicker Curtailment

Simple and Reliable Solution for Shadow Protection

Automatic Shadow Flicker Curtailment
for Maximum Efficiency

To protect residents from stroboscopic effects, a precise shadow analysis is required before the construction of a wind farm. This analysis determines whether and to what extent residential homes or gardens are affected by shadow casting. If legal or agreed-upon shadow times are exceeded, operators are required to limit the rotor runtime during those periods.

This is where Fleximaus comes in: We automatically handle the shadow flicker curtailment of your wind turbines—efficiently and reliably. This avoids unnecessary downtime while ensuring compliance with all regulations.

How Our Intelligent Shadow Flicker Curtailment Works

With Fleximaus, you ensure intelligent and efficient shadow flicker curtailment that protects residents while avoiding unnecessary downtime—through precise sensors, minute-by-minute checks, and customized brightness levels.

Detection of Solar Radiation

Fleximaus uses precise sensors to measure the current solar radiation.

Custom Brightness Values

Freely definable threshold values ranging from 10,000 Lux (overcast sky) to 150,000 Lux (clear midday sky) ensure optimal adaptation to local conditions.

Real-Time Communication

If the brightness values are exceeded, Fleximaus sends a command to the central server in the wind farm.

Minute-by-Minute Analysis

Fleximaus analyzes the conditions every minute to ensure precise shutdowns.

Reduced Shutdown Times

No unnecessary downtime during low solar radiation, as no shadows are cast.

Efficiency and Resident Protection

Rotor operation remains efficient while ensuring reliable protection for residents against stroboscopic effects.

Custom Shadow Flicker Curtailments
for Different Wind Turbines

In order to obtain approval for the construction of your wind farm, a detailed report is required. This report specifies which wind turbine must be shut down on which day and at what time of day. The basis for this are the affected immission points (IP), which are precisely measured and checked. Immission points include, for example, house walls with windows, balconies, gardens of residential buildings, or occasionally used office buildings.

After determining the locations, types, and heights of your turbines, as well as the exact measurement of the IPs, the actual shadow periods, adapted to the terrain, can be calculated. Our experts then create a concept tailored to your wind farm. This not only includes determining which wind turbines require a shadow flicker curtailment but also provides a precise shutdown schedule for each turbine. This ensures reliable compliance with regulations and optimal integration of your turbines into the surrounding environment.
