Research On The Solar Ray Self-Position And Tracking System

In the current social situation of energy shortage,the effective use of solar energy is an important way for easing the pressure of energy sources and utilization of new energy development. A lot of research, how to align the sun light vertical illumination direction in accurate real time is becoming a convenient and feasible implementation plan of solar cell materials innovation direction.Sunlight automatic tracking technology as a convenient and effective to improve the technical feasibility of solar energy absorption efficiency, technological developments now being increasingly wide range of development and utilization. As the sun automatic tracking technology into the core content, how accurate positioning of the sunlight incident direction, is undoubtedly an important aspect of the technological innovation and efficiency.This paper design sun autonomous positioning tracking system, the algorithm and structure of processing on detection mechanism(photosensitive resistance)and the actuator(steering)cascade in the same coordinate system, determine the sun real-time vertical irradiation direction. In this paper based on the theory of photometry, combined with the light detecting element characteristics, established a system model, calculating light incident position and intensity, driving gear with solar panels to the direction perpendicular to the position of the solar tracking. When the solar panel output voltage is less than the battery voltage, the system continues to charge in order to achieve the purpose of dynamic charge in order to achieve intelligent solar tracking system of empowerment.
