Abstract

In Korea, many solar power generation facilities are being installed in mountainous regions, which cover 70% of the country' area. This study aimed to analyze the slope characteristics of solar power generation facilities installed in such regions, considering the potential for mountain hazards. A database was created for 663 mountainous solar power generation facilities in Gangwon province, including data on area, slope angle, slope direction, altitude, and soil depth. GIS techniques were used to analyze the slope characteristics of these facilities. The area of solar power generation facilities installed in the Gangwon Mountains ranges from 606 to 320,718 m2. We found that a notable number of these facilities have slopes exceeding the permit standards for mountain solar power installations and steep slope criteria. In addition, most facilities are located south, making them vulnerable to landslides. The correlation between soil depth and slope or topographical altitude was found to be quite low.

국토의 70%가 산지인 우리나라는 많은 태양광 발전 시설이 산지에 설치되고 있다. 본 연구에서는 산지 재해와 관련하여 산지에 설치된 태양광 발전시설의 사면 특성을 분석하기 위해 663개소의 강원 산지 태양광 발전시설에 대하여 면적, 경사각, 경사향, 고도, 토심 등의 데이터베이스를 구축하였으며, GIS 기법을 활용하여 산지 태양광 발전시설의 사면 특성을 분석하였다. 분석 결과, 강원 산지에 설치된 태양광 발전시설의 면적은 606~320,718m2의 범위를 가지며, 산지 태양광 설치 허가 기준과 급경사지 판정 기준 이상의 경사를 가진 태양광 발전시설이 상당수 존재하는 것으로 나타났다. 또한, 태양광 발전시설은 대부분 산사태에 취약한 남향을 나타내고 있으며, 토심과 사면 경사 또는 지형고도와는 상관관계가 매우 낮은 것으로 나타났다.
