태양광발전단지 건설을 위한 태양광자원 정밀조사

Abstract

Since the solar radiation is the main input for sizing any solar photovoltaic system, it will be necessary to understand and evaluate the insolation data. The Korea Institute of Energy Research(KIER) has begun collecting horizontal global insolation data since May, 1982 at 16 different locations. Because of a poor reliability of existing data, KIER's new data will be extensively used by solar photovoltaic system users as well as by research institutes.From the results, we can conclude that1) The yearly averaged horizontal global insolation of Korea was turned out 3.57 kWh/m2.day in the periods of 1982～2001.2) Horizontal global insolation of spring and summer was respectively 24% and 21% higher than the yearly average value, and that of fall and winter was respectively 12% and 34% lower than the yearly average value.
