Abstract
In the rapid progress towards sustainable energy systems Photovoltaic (PV) systems are notably susceptible to power losses and gaining hotspots due to partial shading, a pervasive issue that significantly diminishes power output. This article presents a systematic review of more than seventy up-to-date relevant articles that are involved in PV array reconfiguration, and their strategic response to combat the detrimental effects of partial shading. These studies were meticulously chosen for their relevance to current PV array practices, their methodological robustness, and the reliability of their empirical or simulated results. The provided analysis is a multi-dimensional assessment of these methods, considering factors such as array size, complexity, execution speed, merits, demerits, acquired parameters, and alongside, validation methods employed. A significant finding from this review is the emerging preference for reconfiguration techniques that blend static and dynamic elements, particularly those employing meta-heuristic algorithms, over purely dynamic approaches. The article presents a comprehensive reference for and a lucid primer in the domain of PV array reconfigurations.
