摘要：

The dynamic behavior of PV-modules is analyzed by different methods. Outdoor measurements of the deflection show their dynamic behavior under wind loads and the correlation between wind velocity and mechanical deflection. Indoor tests were performed with acoustic excitation of the modules with monitoring of the deflection. The frequency range of the resonance frequencies of different modules was between 10 and 100 Hz. Numerical calculations, based on FEM-modeling, yielded a very good agreement with the experimental results. Copyright (C) 2011 John Wiley & Sons, Ltd.
