Design and Implementation of a Prototype Sunflower-Type Photovoltaic System

This manuscript presents the development of a functional prototype of a photovoltaic system named sunflower. It employs linear PID controllers to accurately track solar radiation. The design process initiates with the construction of a light sensor comprising three key components: transducer, conditioning, and postprocessing unit. Additionally, two PID controllers are developed to precisely adjust the position of the photovoltaic system to an orthogonal angle relative to the incident solar radiation. The results demonstrate that the sensing system effectively determines the optimal angle for solar radiation collection by the sunflower photovoltaic system. The designed controllers efficiently maximize the incidence of light energy, ensuring a stable response in the face of input changes or external disturbances. This enhancement significantly improves the prototype's accuracy, stability, and speed, even in scenarios involving multiple light energy sources.
