Abstract

This paper presents a single axis tracking solar photovoltaic system,the system has the advantages of simple structure, high control accuracy, low cost. The tracking system be composed of sunlight sensor, controller, barrel ,motor. It can freely achieve to rotate in the space within the range from 0°to 180°. The sunshine vertical irradiation bias in the solar panel is not more than 0.3°. Compared with the fixed photovoltaic system,it can effectively improve the utilization efficiency of solar energy.
