One of the challenges in designing the grounding for a Utility Scale Photovoltaic Power Plant is understanding how the system is actually connected, as there are different configurations. In many such systems, the grounding system is common from the DC grounding conductors and the AC grounding conductors.
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.
(iv) The gap between the photovoltaic modules in the North–South direction is affected by the longitudinal spacing for maintenance, and it gives rise to a smaller influence of the parameter length of the rack configuration on the number of photovoltaic modules that can be installed in that direction.

On a large, utility-scale photovoltaic power plant, the solar panels (or modules) can be installed either on fixed, ground mounted structures, facing South at an angle depending on the latitude of the site, or they can be fixed on mobile structures called solar "trackers" which rotate on one or two axes so that the solar panels face the sun all day long.
This particularly increases generation during times of low solar zenith angle, leading to increased energy generation during peak demand periods in the early morning or early evening [187]. Higher albedo surfaces also have a cooling effect by reflecting sunlight, lowering the operating temperature of PV modules, increasing efficiency and lifetime [ 188, 189 ].
