ABSTRACT Photovoltaic (PV) arrays have gained significant attention in recent years due to their potential for sustainable energy generation. However, the reliable operation of PV is crucial optimal performance and long‐term durability. The early detection faults vital prevent further damage, improve maintenance strategies, ensure uninterrupted production. In this study, we propose a novel fault method based on Time Frequency Analysis (TFA) using Scaling Basis Chirplet Transform (SBCT). proposed method, array signal decomposed into set chirplets SBCT. represent localized time‐frequency components that can capture dynamic behavior signal. To evaluate effectiveness extensive simulations experiments are conducted real‐world data. SBCT with combination various machine learning algorithms detect array. Support Vector Machine, Decision Tree, Random Forest, ANN classifiers able 99%, 98.5%, 99.2%, 99.5% accuracies no shading condition 88%, 85%, 89%, 89.5% severe condition. achieves high accuracy robustness detecting types arrays, even presence noise uncertainties. TFA offers promising solution efficient arrays. It enables detection, facilitating timely minimizing losses. approach contribute enhancing overall performance, reliability, lifespan thereby advancing adoption renewable sources promoting development.
