One-time measurement of irradiation intensity of Solar Simulator using cds photo-sensors

cds 광전소자(光電素子)를 이용한 인공태양(人工太陽) 일사강도(日射强度)의 동시측정(同時測定)

There are two kinds of irradiation intensity deviation, depending on time and position, on illuminated plane when thermal performance of solar collector is tested by using solar simulator. In this study we measured only position deviation of irradiation intensity using 45-cds photosensors and data acqusition system and found the point of average value. By this result we can improve the accuracy of irradiation measurement in indoor test of solar collector.
