Abstract

This paper presents an optimal layout design of rooftop photovoltaic (PV) system that maximize the power output for each building in Kangwon National University's Samcheok Campus. The available area was calculated by excluding fixed facilities and shaded areas on the roof of each building. The inclination of module was set to onsite latitude value. Considering the characteristics of rooftops, two layout designs of the solar module were applied (southeast facing - parallel to the rooftop boundary that maximizes the number of modules and south facing that maximizes PV power generation efficiency) to 14 buildings to analyze and compare the PV potentials. As a result using the RETScreen software generally used, the southeast-facing installation method showed higher potential for 11 buildings, while the south-facing installation method was selected as the optimal design for three buildings. This result can be used as basic data for designing the rooftop PV system.

본 연구에서는 강원대학교 삼척캠퍼스 옥상 공간에 태양광발전시스템을 도입할 경우, 건물별로 발전량을 최대화하는 최적 배치 설계 방안을 제시하였다. 각 건물 옥상의 고정시설물과 음영 지역을 제외하여 태양광 모듈 설치가 가능한 면적을 계산하였다. 태양광 모듈의 설치 경사는 연구지역의 위도 값을 적용하였다. 건물 별로 옥상 공간의 면적과 형태가 상이한 특성을 고려하여 태양광 모듈을 옥상 경계와 평행하게 남동향으로 설치하는 방법(태양광 모듈 개수 최대화)과 남향으로 설치하는 방법(태양광 발전 효율 최대화) 등 2가지 설계 방법을 14개 건물에 적용하여 설계안에 따른 옥상 태양광발전시스템의 발전 잠재량을 비교 분석하였다. RETScreen 소프트웨어를 이용하여 분석 결과 11개 건물은 태양광 모듈 개수를 최대화하는 남동향 설치 방법이 더 높은 잠재량을 나타낸 반면, 3개 건물은 태양광 발전 효율을 최대화하는 남향 설치 방법이 최적의 설계안으로 선정되었다. 본 연구는 강원대학교 삼척캠퍼스 옥상 태양광발전시스템 설치를 위한 기초 설계 자료를 제공할 수 있을 것으로 기대한다.
