PVsyst에 의한 태양광 발전량 예측 및 실측치와의 비교 연구

다국어 초록 (Multilingual Abstract)

With the global implementation of carbon neutrality policies, photovoltaic (PV) power generation is gaining attention as a key energy source. As the adoption of BIPV (Building-Integrated Photovoltaics) and BAPV (Building-Applied Photovoltaics) systems increases, installations of PV modules in various orientations are also becoming more common. Accordingly, research on the accuracy of PV output prediction tools such as PVsyst is needed, but studies in this area remain limited. In this study, PV output was measured at two tilt angles (30° and 90°) and five orientations (east, west, south, north, and horizontal), and the error rates between the measured values and PVsyst predictions were analyzed. The average error rates across eight selected days were: for 90° tilt — 5.3% (horizontal), 15.5% (east), 7.1% (west), 7.2% (south), and 16.5% (north); and for 30° tilt — 5.3% (horizontal), 5.5% (east), 3.5% (west), 4.9% (south), and 16.5% (north). This study is expected to contribute to evaluating the prediction accuracy of PVsyst under diverse installation conditions and enhancing the reliability of PV output analysis.
