Mitsubishi FA-Based Solar Photovoltaic Tracking Control System

Abstract

A sort of two axes auto- tracking solar photovoltaic system based on Mitsubishi FA productions to solve the problem of low conversion efficiency in existing systems. It is discussed that how to design frames of input、control、execution 、functions and control strategies. The method of timing light intensity comparison is proposed to achieve automatic tracking of solar cells. This system can regulate automatically the horizontal angle and the vertical angle of the battery board by controlling circuits of sensors, plc, transducer and amplifier. Sound results are shown by tracking maximum conversion efficiency of this system.
