Abstract

Agrivoltaic systems (AVS) is defined as combining farm-grown crops with photovoltaic panels (PV) installed several meters above the ground. Solar radiation (W/㎡), photosynthetic photon flux density (PPFD, µmol/㎡/s), air temperature (℃), vapor pressure (kPa), soil moisture (㎥/㎥), soil temperature (℃), wind direction (˚), and wind speed (m/s) were measured under the AVS in Boseong-gun during winter barley season. Data was collected by 5 minute interval. All data can download at Github site (https://github.com/chojaeil/AVS_Boseung). To gap-filling missing solar radiation data during about two weeks, the conversion coefficient from solar radiation to PPFD was estimated as 0.41. Further, according to the ratio of diffuse radiation to direct radiation, the maximum value among the twenty PPFD sensors under the AVS was related to the PPFD value of filed.

작물을 재배하는 동시에 전력 생산도 가능한 영농형 태양광 발전은 농업·농촌 분야와 재생에너지 산업 모두로부터 주목 받고 있다. 하지만, 그 역사가 짧은 만큼 영농형 태양광 하부에서의 미기상 환경 변화에 대한 이해와 관측 방법론이 정립되지 않은 실정이다. 따라서 본고에서는 보성군에 설치된 영농형 태양광에서 2019년 11월 부터 2020년 5월까지의 보리 생육기간 동안 일사광, 광합성유효복사광, 기온, 습도, 토양습도·온도, 풍향·풍속을 5분 간격으로 측정하여 공개했다. 또한, 노지의 일사량 및 광합성유효복사량에 대한 약 13일 간의 자료 결손에 대해서는 가까운 기상청 관측 자료를 활용하거나 영농형 태양광 하부의 자료를 이용한 두 가지 경험적 메우기 방법을 제안하였다. 본고 자료가 영농형 태양광에 대한 농업적 평가에 다양하게 활용되기를 기대한다.
