Özet: The objective of this study is to decide a spatial interpolation method for estimating solar radiation in South Korea for the suitability analysis. Firstly, the study extracted regression equations between sunshine duration and solar radiation for 22 meteorological stations. We used the Tiessen method for estimating solar radiation with 22 stations because the 55 stations do not observe solar radiation. The stations in same polygons have same regression equations to estimate solar radiation from sunshine duration. The estimated solar radiation of 77 stations uses an interpolation for spatial distribution of solar radiation. We used methods of interpolation as IDW, Spline, SK and OK. As a result, the OK method shows that the lowest MAE and RMSE. The results obtained are resonable and an obvious finding from spatial distribution idicated that OK approach is a very useful tool for the unknown regions.
