Photovoltaic (PV) energy has become recognized as an important alternative energy source because of its efficient
conversion method. Nevertheless, issues such as partial shade and faults can considerably diminish the power output of PV
arrays, requiring the implementation of efficient fault detection and diagnosis methods to ensure safe and optimal operation.
This article presents a simplified mathematical model for photovoltaic (PV) systems and proposes a fault detection method
based on the use of solar irradiance, voltage, and current parameters. The system utilizes voltage and current ratios, together
with irradiation data, to determine threshold values that can be used to diagnose different fault modes. The fault detection
approach has been examined on a 4×4 PV array with a power capacity of 1600 W using MATLAB/Simulink R2019a. The
method's accuracy has been verified by further experimental setups. The results demonstrate that the technique is
uncomplicated, requires a smaller amount of data for identifying defects, and automatically characterizes faults with a high
level of precision.
