A digital Twin as the solution to aerolastic phenomena
In recent years, the solar photovoltaic sector has followed a clear trend toward lightweight supporting structures to reduce costs and improve competitiveness. However, this approach—combined with new regulatory and site conditions—has increased the importance of aeroelasticity in photovoltaic installations as a critical factor for plant safety and lifespan.
Aeroelasticity results from the interaction between wind, the supporting structure, and the dynamic behavior of PV panels. Under strong or turbulent wind conditions, this interaction can cause vibrations, resonances, and deformations that directly affect the structural performance of PV systems.
The combination of increasingly lighter structures and high-wind locations makes many solar plants especially sensitive to aeroelastic effects.
Key risks include:<ul type=”disc”>
- Premature structural fatigue of supports and
anchors- Dynamic resonances induced by wind
- Overstressing of critical components
- Panel misalignments
- Development of microcracks that shorten
equipment lifespanIn extreme cases, these phenomena can lead to serious structural failures or compromise plant safety.
To address these challenges, CADE has developed AnemioT, a Digital Twin specifically designed to prevent and mitigate aeroelastic effects in PV installations, both during construction and operation.
AnemioT is installed at key points in the plant and operates through real-time sensors, continuously analyzing:
<ul type=”disc”>
- Incoming wind flow
- The structural condition of PV supports
Based on this analysis, the system acts preventively to avoid resonances, overstressing, misalignments, and microcracks, helping to extend equipment lifespan and maximize overall energy production.
