3W PV Generation System Development with Solar Tracker

3kW급 추적식 태양광발전 시스템 개발

In photovoltaic generation, PV module is used to generate the electricity, and this system has been in limelight as nonpolluting alternative energy source. But, as energy density is low and PV module cost is high, there is a disadvantage that initial investment cost go up. In this study, we studied the method of allowing a tracker, adequate to photovoltaic generation, for Increasing the generating. We determined the proper error angle in order to decrease the repeating number of tracking without a reduction of the generating by using our developed simulator. And, we presented the photovoltaic approach tracking control and achieved its experiment. Through the result of experiment, it is expected that the fault rate and the consumption of electric power in a tracker get reduced and its cost become cut down.
