Generalized severity, occurrence, and detection rating criteria are developed that can be used to analyze various solar PV systems as they are or with few modifications. The analysis is based on various data sources, including field failures, literature reviews, testing, and expert evaluations.
The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s. A longer test must be used to verify the system performance under a range of conditions.
In literature, three general maintenance strategies for solar PV systems are mentioned: corrective, preventive, and predictive maintenance. Fig. 8 shows the evolution of maintenance strategies over time, along with examples of maintenance activities for PV systems. Fig. 8. Evolution of maintenance strategies.
A reliability analysis can estimate a solar PV system's expected performance over its lifetime. It can help determine whether the system performs optimally or if any potential issues may affect its long-term reliability. A solar PV system's reliability is directly linked to its economic viability.
