The integration of artificial intelligence into solar power systems indicates an immense change in renewable power design, optimization, and management. As the solar energy share in the global electricity generation is increased, the demand for smart, data-hinged control and prediction mechanisms becomes overwhelmingly critical. <\/span>AI applications in smart solar-powered systems<\/span> provide the necessary means to address various challenges that accompany solar power generation and distribution. The main challenges are mainly variability, intermittency of the generated power and also nonlinearity of the system. AI methods overcome such issues through predictive modeling, adaptive optimization, and autonomous decision-making (<\/span>Teta et al., 2024<\/span><\/a>; <\/span>Mishra et al., 2023<\/span><\/a>).<\/span><\/p>\n

Machine learning and deep learning algorithms are powerful tools that are able to extract complicated spatiotemporal attributes from meteorological and operational datasets. These methods are very commonly used for solar irradiation prediction, energy dispatch strategy improvement, and enhancement of photovoltaic (PV) system reliability (<\/span>Guermoi et al., 2022<\/span><\/a>; <\/span>Franco et al., 2025<\/span><\/a>). Moreover, machine learning techniques are also employed for maximum power point tracking (MPPT), fault detection, and predictive maintenance in order to increase PV installations\u2019s overall efficiency and lifespan (<\/span>Abouzeid et al., 2024<\/span><\/a>; <\/span>Rukhsar et al., 2025<\/span><\/a>; <\/span>Ledmaoui et al., 2025<\/span><\/a>).<\/span><\/p>\n

AI merges with the Internet of Things (IoT) and spans the smart <\/span>solar-powered systems <\/span>\u00a0by helping real-time monitoring, fault diagnosis, and remote optimization through various interconnected sensor networks (<\/span>Kaiss et al., 2025<\/span><\/a>; <\/span>Wali & Khan, 2021<\/span><\/a>). These AI-oriented IoT systems still face many issues regarding data quality, interpretability, and model generalization, all of which limit the large-scale deployment of such systems in <\/span>solar energy systems control <\/span>\u00a0(<\/span>Ukoba et al., 2024<\/span><\/a>; <\/span>Afridi et al., 2021<\/span><\/a>).<\/span><\/p>\n

The increasing amount of research in <\/span>AI applications in solar energy systems <\/span>is proof that AI is an important actor in the advancement of solar technologies toward more efficiency and adaptability. By exploiting such techniques, the field of solar energy has already seen progress toward an era of self-regulating smart solar power control systems that are able to independently forecast, optimize, and maintain their performance under dynamic environmental conditions. This article discusses some of the key applications of AI and their associated challenges in solar energy systems, including: forecasting direct irradiation, dispatching and energy management,Internet of things (IoT) ,fault detection, and predictive maintenance.<\/span><\/p>\n

1. Outline of Machine Learning Algorithms, Techniques and Methods<\/b><\/h2>\n

Machine learning (ML) and artificial intelligence (AI) are increasingly integrated into solar-powered energy systems, as they help\u00a0 to improve the overall system\u2019s performance. Fig. 1 shows a general classification of machine learning techniques. Solar energy systems leverage machine learning’s ability to learn from historical and real-time data in order to produce more adaptive responses to various fluctuating environmental conditions. For instance, supervised learning methods (that learn a mapping from inputs to known target outputs by using labeled data), like support vector regression, are used for prediction tasks, while unsupervised learning techniques (that discover possible structure in unlabeled data) help discover patterns in system behavior. Reinforcement learning methods enable real-time decision-making. Deep learning models (e.g., ANNs, CNNs, and RNNs) manage complicated spatial and temporal data while improving the accuracy of classification and\/or forecasts. Alongside modeling techniques, selecting the right input (features) plays an equally critical role in shaping model performance and reliability. Feature selection identifies the most relevant inputs of the model and therefore plays a key role in improving model efficiency and accuracy.\u00a0 Below is a quick review of feature selection, machine learning, deep learning, and meta-learning techniques.<\/span><\/p>\n

It is worth mentioning that in this context, \u2018modeling\u2019 refers to making a data-driven description of how a solar powered system behaves under dynamic environmental and operational conditions.\u00a0<\/span><\/p>\n

1.1. Feature Selection<\/b><\/h3>\n

Feature selection is a process that helps reduce noise and enhance prediction accuracy by choosing the most input variables for the predictive model. In this regard, we use various machine learning algorithms (<\/span>Castangia et al. 2021<\/span><\/a>). Fig. 2 shows a simple diagram explaining how feature selection works. The first row represents all features in the data set. The second row are the most important features identified by the feature selection algorithm. The last row is the pruned dataset, which only encapsulates the most influential features.<\/span><\/p>\n

1.2.1. Machine Learning Techniques<\/b><\/h4>\n

Although this article concedes that deep learning methods are commonly classified as subsets of machine learning techniques, the two groups are differentiated so that a more focused section can be assigned to each method. Therefore, the term \u2018machine learning methods\u2019 refers to techniques that, in contrast to deep learning methods, classify and forecast without using multi-layer neural networks for automatic feature learning, which results in using less data for training and more transparency.<\/span><\/p>\n
