An intelligent photosensitive tracker for concentrating PV system
this paper presents the design of an intelligent photosensitive tracker which is used to improve the efficiency of the solar energy converted by concentrating PV (CPV) systems. The photosensitive sensor outputs real-time signal sampled by multi solar cells. These signals will be used to judge the light intensity and to realize the tracking function. Two operating modes (photosensitive sensor tracking and timing tracking) and wake-up function are designed in the system. Namely, four divided photosensitive quadrants cross-collect signal in real time; the system compares these signals and sends control commands by MCU to drive two stepping motors for controlling the position and orientation of solar cells; the center solar cell through light intensity detection completes the switching of operating modes. Finally, through the system sensitivity test and comparison test of power generation between one solar cell with this intelligent photosensitive tracker and another one solar cell fixed south-facing 45 degrees, the one who used intelligent photosensitive tracker is better, and the converted solar energy is increased by up to 34.77％.
