Investigations of the response of a photovoltaic power generator to mechanical vibrations — •Julian Schmid¹, Erika Kancsar¹, Markus Drapalik¹, Viktor Schlosser¹, and Gerhard Klinger² — ¹Faculty of Physics, University of Vienna, 1090 Vienna, Austria — ²Department of Meteorology and Geophysics, University of Vienna, 1090 Vienna, Austria

Due to their large area and the exposure to wind forces photovoltaic solar modules are subjected to mechanical vibrations which can generate electrical oscillations. The resulting electromagnetic signal is partly emitted to the ambience and partly carried through the leads to the power conditioning system of the solar power generator. Purpose of the current work is (i) to investigate the response of photovoltaic devices to mechanical vibrations in the laboratory under well controlled conditions and (ii) to perform exemplary outdoor studies of the mechanical vibrations caused by wind forces in Vienna. The results collected so far will be presented and discussed with respect to the impact of mechanical vibrations of solar arrays on the level of electromagnetic distortion.
