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.
Plane of Array Irradiance, the sum of direct, diffuse, and ground-reflected irradiance incident upon an inclined surface parallel to the plane of the modules in ... Key Performance Indicators …
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.
