So essentially I should run a min #8 ground to the shed in order to bond both the well casing and pv array despite the fact that they both serve as grounding electrodes themselves, and this in order to open the appropriate breakers in the case of a ground-fault.
Grounding a PV System does 5 Things: It drains off accumulated charges so that lightning is NOT HIGHLY ATTRACTED to your system. If lightning does strike, or if a high charge does build up, your ground connection provides a safe path for discharge directly to the earth rather than through your wiring.
Solar PV systems are still permitted to be grounded, per 690.41(A)(1) and (5), and, for those PV systems that are, the dc grounded conductor is directly coupled (or coupled through electronic circuitry) to the ac grounded conductor, which is then brought to ground potential by being terminated to the neutral bus bar at the main service panel .
Panel longevity: Proper grounding of solar panels can prevent potential-induced degradation (PID), extending their lifespan. Overall system stability: A good earthing system contributes to the overall electrical stability of the installation, reducing wear and tear on components.

6 FAQs about [Is it possible to borrow the grounding of photovoltaic panels ]
Do solar PV systems need to be grounded?
Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later). The NEC also outlines requirements for grounding electrodes (like ground rods) and how they should be installed.
Why do PV systems need a grounding system?
As installed PV systems age, grounding issues emerge that impact system safety. These issues include deteriorating electrical connections, inadequate grounding device design and installation, and the effects of non-code compliant system installations.
Why is proper grounding of a photovoltaic power system important?
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.
Should I ground my solar panel system?
By considering these additional factors, you can ensure your grounding system is tailored to your specific needs and maintains its effectiveness over time. Properly grounding your solar panel system is a critical step that should never be overlooked or rushed.
Does a photovoltaic system have a DC grounding system?
Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).
What is effective grounding in photovoltaic (PV) systems?
Effective grounding in photovoltaic (PV) systems is the creation of a low-impedance reference to ground at the AC side of the inverter—or group of inverters—that is designed to be compatible with the distribution network’s requirements and existing grounding scheme.
