Why Your Solar Panels Could Endanger Grid Workers (And How Anti-Islanding Stops It)
When a portion of the electrical grid loses connection to the main power supply but continues receiving electricity from distributed generators like solar photovoltaic systems, a dangerous condition called islanding occurs. This phenomenon transforms what should be a dead section of the grid into an energized island, creating severe hazards for utility workers performing repairs, damaging equipment, and degrading power quality for consumers who unknowingly remain connected.
Anti-islanding protection has become a fundamental requirement in grid-connected PV systems, mandated by standards such as IEEE 1547 and UL 1741. These safety …
