The sources of electromagnetic interference from solar systems are typically grid-connected photovoltaic (PV) inverters and optimisers. Off-Grid inverters convert DC power stored in batteries to AC power. Off-Grid inverters typically deliver one of three output waveforms; square wave, modified square wave or sine wave.
With the proliferation of renewable sources such as photovoltaic (PV) arrays and wind turbines in the power grid, the issue of electromagnetic interference started to appear and threaten the system.
Federal Aviation Administration (FAA) guidelines suggest that any interference with radar, navigation aids, or infrared communications should be checked before the solar panels are actually installed. Interference with infrared communications might occur due to increased temperature of the panels in the full sunlight.
It is co-located with a solar panel system at 20 meters distance. The interference level is measured to 60 dBμV/m at a distance of 1 meter from the solar panel system. In this case the interference from the solar-panel system reduces the communication range to about 19% of the maximum possible range.
