FES-image of the wind-speed distribution around a solar module frontally exposed to wind. The arrows indicate the direction of the air currents.

We use the finite element method (FEM) to investigate thermo-mechanical loads on PV modules during production and operation. The resulting understanding of the loads reveals weaknesses and potential for improvement in the structures under investigation.

We have further simulation competences in the field of temperature simulation, flow simulation and electric fields as well as magnetic field analysis.
