However, as suggested [ 8 ], the identification of possible violations may show a lack of EMC standards specific to the various items of equipment that comprise grid-connected photovoltaic systems, principally the photovoltaic (PV) inverter.
Solar photovoltaic (PV) facilities are particularly susceptible to EMP since PV systems are outdoors and exposed to EMP radiation. To assess and mitigate this threat, this paper summarizes various models and tests used to study the effects of EMP on PV systems, assesses the nature of the threat, and identifies measures to mitigate it.
Additionally, the Code of Federal Regulations, Title 47, Part 15 regulates radio frequency (RF) emission from commercial products and many PV inverter manufacturers do qualify their residential or utility-scale equipment to this standard.
Without adequate protection, EMP can severely damage equipment or result in circuit breakdowns or short circuits. Solar photovoltaic (PV) facilities are particularly susceptible to EMP since PV systems are outdoors and exposed to EMP radiation.
The Federal Aviation Admiration (FAA) has indicated that EMI from PV installations is low risk. PV systems equipment such as step-up transformers and electrical cables are not sources of electromagnetic interference because of their low-frequency (60 Hz) of operation and PV panels themselves do not emit EMI.
Different pulse generation standards need to be selected before the testing of the PV system. The impedance-based PCI method provides a fast and efficient test method for PV equipment and systems to estimate the susceptibility level of PV to EMP E1. The variety of equipment of PV systems requires different mitigation methods.
