Up to date little attention has been paid to the interaction of photovoltaic solar cell arrays with electromagnetic fields. Primary arrays of solar panels can act as passive shields, reflectors and antennas for RF radiation. The reception of electromagnetic radiation from the ambience by the solar modules introduces electrical noise into the subsequent system. Under laboratory conditions we currently investigate electrical AC signals detected at the terminals of single solar cells and small modules under well controlled ambient parameters. The signals are introduced by RF radiation emitted by function generators in the range between 10Hz and 4GHz. Beside the laboratory examinations an outdoor facility on the roof top of the department building in central Vienna was equipped with the necessary instruments to record RF signals from the ambience and the electrical noise of a solar module under realistic operating conditions. Results of these investigations will be discussed in order to evaluate the contributions of solar arrays to electromagnetic ambience.
