▶
Reason is that the electrical charge remains in the capacitor after the DC switch
hasbeenswitchedo󰘯.Therefore,atleast5minutesmustlapsebeforethecapaci-
tor has been electrically discharged.
▶
PV modules generate electrical energy when exposed to sunlight, and this may
present an electrical shock hazard. DC voltages on the PV array can reach up to
1100 V.
