Abstract:
Measurements of both conducted and radiated emissions from solar panel installations have been performed. Emissions from photovoltaic systems have previously disrupted radio communication and the purpose of the measurements was to map how emissions from photovoltaic systems can occur. Conducted emissions were measured for frequencies 10kHz – 200 MHz and radiated emission for 10 kHz – 1 GHz. Measurements were carried out with inverters in the facilities both on and off. The conducted measurements showed that even if the inverter is switched off, there are signals in the system. When the inverter was on, a number of characteristic signals were generated which were repetitive in frequency, for example at 200 kHz intervals. These signals were also present in several of the emission measurements on different frequency bands. At the measurement distance of 20 m, the measurements showed an evident increase of the radiated interference level.
