Industry 4.0 represents the evolution of industrial production towards an intelligent and connected environment, in which systems are interconnected and use information and communication technologies (ICT) for control and management. In the solar PV sector, the implementation of Industry 4.0 can optimize operational efficiency and product quality, lower costs and increase competitiveness. Consequently, research is underway to develop and exploit advanced algorithms, such as statistical models, neural networks, support vector machines, clustering tools and other machine learning techniques, applied to the solar PV industry and associated services.
