Artificial Intelligence (AI) is a branch of computer science that aims to create intelligent machines. A less ambitious but attainable approach deals with programing computers for finding solutions to complex problems in a way that simulates human-like logic instead of binary logic. This generally involves borrowing characteristics of human intelligence and integrating them as computer algorithms. First, several AI approaches are recapitulated. Second, artificial neural networks, probably the most used AI technique, are reviewed. Then, fuzzy logic, a method with great potential in forecasting solar irradiance, is introduced. The chapter core consists of two fuzzy models, one for nowcasting solar irradiance and another one for forecasting solar irradiation at daily lag. The discussion is focused on both model construction and accuracy.
