Design and Construction of Prototype Mobile Sun-Tracking System for Concentrator Photovoltaic System

摘要

This paper proposes a mobile sun-tracking system, which allows continuous tracking of the sun and effective harvesting of solar energy on mobile platforms. Based on the dynamic sun-tracking algorithm which we previously proposed, the system takes not only the date, time, and geographical information, but also the dynamic changes of coordinates of the mobile platforms into account to calculate the hour angle of sun relative to the ideal azimuth elevation axes in real time. The advantage of this design is that it can be easily duplicated for mass deployment on the land or ocean. Our results show that the accuracy of mobile tracking in stationary state is 8.085 mrad while the accuracy in mobile state is 127 mrad on average.
