The Efficiency Improvement of the Stand-alone Photovoltaic Power Systems

Abstract

An automated solar tracking system was developed to improve the power generation efficiency of standalone photovoltaic systems. In the system, the discrete-continuous tracking with the adjustable discrete pitch was implemented. In addition, the technique and the algorithm of the standalone photovoltaic power system control was developed for the positioning. The technique provides the minimization of the power consumption when tracking and controlling and supports tracking accuracy adopting it to actual illumination changes.
