A Study on the Optimal PV-module Design for Efficiency Improvement of Photovoltaic System

태양광발전시스템의 효율 향상을 위한 태양전지 모듈의 최적 설계에 관한 연구

The construct of photovoltaic module array, main power source of photovoltaic system, is very important to the efficiency improvement of whole photovoltaic system. Photovoltaic modules are usually connected in series or parallel to meet power capacity required. Since output characteristics of a photovoltaic module are greatly fluctuated on the variation of insolation, temperature and its type, the maximum open circuit voltage and output operating voltage of photovoltaic module array must exist in the admissible input voltage range of inverter system under any operating conditions. In this paper, we present the selection and array method of photovoltaic modules through simulation for the coupling loss reduction between photovoltaic modules and a inverter.
