In a photovoltaic (PV) system, the grounding electrode system is essential for ensuring electrical safety through proper grounding. This system establishes a connection between the electrical equipment and the ground, which helps to divert any fault currents safely into the earth. This is vital for protecting the system components and reducing the risk of electrical shock to individuals who might come into contact with the equipment.

Grounding also plays a critical role in stabilizing voltage levels within the system, minimizing lightning strike risks, and preventing electrical surges. By providing a path for fault current, it enhances the overall safety of the PV installation, protecting both the equipment and the personnel working with or near the system.

While other aspects such as energy efficiency, reliability of power supply, and energy production are relevant to PV systems, they are not the primary function of the grounding electrode system. The primary focus here is on electrical safety, making this the correct answer for the question about the grounding electrode system's role in a PV installation.
