Do solar farms create electromagnetic interference?
According to USA’s National Renewable Energy Laboratory (NREL) solar power systems are at low risk of electromagnetic interference (EMI).
Electromagnetic interference (EMI) refers to radio frequency (RF) emissions that can affect nearby communication devices and navigational aids.
However, USA’s Federal Aviation Administration (FAA) has said that EMI from solar panels has a low risk.
PV systems equipment like transformers and cables do not produce EMI because they have a low frequency of operation.
The only component of a solar panel system that may be capable of emitting EMI is the inverter, but they also produce very low levels of EMI (similar to electrical appliances), and the EM field is at or below background levels at a distance of 45 meters from the inverter.
Proper grounding, filtering, and circuit layout reduce potential EM radiation.
