Abstract :
Mechanical vibrations of a solar module cause oscillations in the orientation of the module towards the sun, resulting in a low frequency a.c. current component at the module´s terminals. We have investigated this effect and performed model calculations in order to estimate the influence on the feed back control of a converter.
