Isolating the danger (Rooftop Solar Panels) | Electrical connection


“Accessing a roof with solar panels could place electricians, emergency service personnel and home owners at risk of electrocution. Even after following the standard procedure of isolating the DC isolator at the switchboard and the PV isolator on the roof, lethal DC voltages can continue to be generated throughout the solar panels and the associated wiring.”

“A damaged solar array can create unpredictable current
paths which can make live gutters, the roof and the modules.”
