Research on Sun-tracking Control System in Solar Photovoltaic Power and Its Design

The solar energy is utilized for protecting the environment of the earth.Photovoltaic power is one way of solar power utilization.It is very important to further improve the efficiency of its device.This is an important question which has need to be solved at present.Through researching on its tracking control system which is widely used,the feed-forward and closed-loop control tracking scheme is proposed to improve the tracking efficiency of solar photovoltaic panel.The solar photovoltaic panel rotation angle for the feed-forward track is obtained according to the trajectory of the sun.The photoelectric sensor is used to detect the photoelectric signal for the closed-loop control of solar photovoltaic panel,so that the errors of the tracking devices of solar photovoltaic panel are overcome during the installing,production and processing and the tracking control accuracy is improved greatly.
