Design and Implementation of Tracking System for Dish Solar Thermal Energy Based on Embedded System

摘要

Solar thermal energy has lots of advantages compare with photovoltage (PV). Most of previous study of sun tracking system looked at PV, whose accuracy and stability can't satisfy the requirements of thermal energy system. This paper gives a design and implementation of tracking system for dish solar thermal energy based on embedded system that mixes active and passive tracking, uses more stability sensors and adopts exception handling algorithm to improve both accuracy and stability. Experiments show that the design is effective.
