모듈의 설치환경에 따른 영농형 태양광 시스템 전기적 특성 및 작물 생산량 변화

초록

Agricultural solar systems are highly space efficient systems that enable simultaneous agricultural and power production on the same farmland. The amount of solar radiation reaching the ground surface and the degree of shading generated vary depending on the conditions of the installed modules, necessitating precise design. Using PVSYST simulation, we analyze the module’s power output, the solar radiation reaching the ground surface, and the PPFD and DLI while varying the module installation angle, azimuth angle, and the installation distance (pitch) between modules to predict the relative crop yield Results show that increasing tilt angle strongly improves ground PPFD/DLI by reducing ground shadow and enlarging sky and ground view factors. Higher tilted angle (60– 90°) makes higher irradiance on the bottom ground and higher crop production. 30–45°. Wider pitch (≈6–10 m) further mitigates shading, lifting DLI to ≥20 mol/m ･day across the growing season. The recommended envelope for Korean agrivoltaics is high-tilt (≥ 2 60°) with ≥6 m pitch, balancing crop preservation and power output.
