However, implementing advanced monitoring techniques in large-scale PV systems can result in higher maintenance costs due to additional hardware installation, increased power demands, and the need for trained personnel. 3.3. Predictive maintenance
This highlights that the management of PV systems often focuses on closely monitoring energy production, neglecting the overall efficiency of the system affected by global operations such as preventive maintenance, cleaning, and relevant logistical tasks.

The financial aspects of a PV plant are based on different economic indicators. Capital expenditure (C A P E X) represents the initial costs of PV installations, while operational expenditure (O P E X) covers expenses related to site operation, maintenance, taxes, labor, and outsourced services, among others.
Other maintenance metrics such as response time (R T) and the proportions of corrective maintenance (C M) and preventive maintenance (P M) have been utilized for both the entire PV plant and specific subsystems with multiple arrays and inverters,, .
