Proper grounding of a photovoltaic (PV) power system is critical to ensuring the safety of the public during the installation’s decades-long life. Although all components of a PV system may not be fully functional for this period of time, the basic PV module can produce potentially dangerous currents and voltages for the life of the system.
Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.
existing hardware standards. As the power output of PV systems continues to increase with each new generation product, grounding is likely to become even more of an issue. As PV system configurations evolve and new equipment comes on the market, equipment and system grounding protocol

In any ground-fault scenario on the DC side of a grounded PV system, ground-fault currents from any source (PV modules or batteries in stand-alone systems) must eventually flow through the DC system bonding jumper on their way from the energy source through the fault and back to the energy source.
PV array modules and conductor capacitance to ground can contribute significant shock hazards in the form of a capacitive discharge on ungrounded systems. Resistance grounding can eliminate the charge on these distributed capacitances. Grounded: On grounded systems, the first ground fault will cause currents to flow.
