In this work, a new method to obtain the effective ground conductivity value in the middle frequency band where the informations of soil characteristics are insufficient was proposed. The proposed method obtained the effective ground conductivity values with the measured field strength from sea reference stations and general attenuation model in the middle frequency band. In addition, the proposed method used statistical method to minimize the error between the measurements and the predictions. Then, the effective ground conductivity in Korea peninsular was obtained by using the proposed method. Finally, it was verified that the effective ground conductivity using the proposed method is useful to predict electric field strength in the middle frequency band.

The following study was conducted to determine the optimal location in terms of efficiency for solar energy facilities, and to propose a policy implications for the orientation of the installments. 92 cases in Jeollanam-do Province were selected. A regression analysis was performed between the average electricity generation time as the dependent variable, and the facility, weather and site conditions as the independent variables. As a result, 5 variables were deemed significant. Larger site areas, closer proximity to rivers, islands, oceans, etc., least south-oriented, higher average wind speed, and facilities in agricultural land use and natural environment conservation land use had the highest efficiency. This study minimized the possibility of secure databases and errors following facility types, and was limited in the number of sites studied, since this was only conducted in Jeollanam-do Province. Nevertheless, these conclusions still offer important policy implications for determining the most optimal location for solar energy facilities.
