South Korea plans to mandate Zero Energy Buildings (ZEB) for all new public buildings by 2025 and for all new buildings by 2030 to address climate change and reduce energy consumption. ZEBs minimize energy usage and produce sufficient energy on-site to achieve net-zero energy consumption, necessitating the use of all available building surfaces for energy production. Building Integrated Photovoltaics (BIPV), integrating solar panels into building surfaces, is gaining attention. While solar systems are typically installed facing south for maximum efficiency, urban environments often prevent all buildings from being south-facing. Research indicating increased global irradiance suggests the feasibility of installing solar panels on north-facing surfaces. Accurate energy production prediction using simulation software like PVsyst is crucial for BIPV feasibility studies. However, existing studies show significant discrepancies between simulated and actual values on north and west-facing surfaces, affecting economic reliability. This study analyzes and corrects these discrepancies by comparing the actual and simulated photovoltaic output of panels installed in all directions, aiming to improve simulation accuracy.
