Abstract

This study aimed to investigate the feasibility and potential applications of utilizing bifacial photovoltaic (PV) panels from an architectural perspective. It also aimed to establish a foundational dataset for installation and operational guidelines for bifacial PV panels through a comparative analysis of energy production performance with single PV panels. The research encompassed several key steps, including a comprehensive literature review, calculation of solar surface radiation values, development of datasets for bifacial and single PV energy production, and a performance comparison between both approaches. The results of the study show that bifacial PV panels exhibit optimized energy production capabilities within the range of 40 to 80 degrees, contingent upon the specific installation location. Consequently, it is recommended that the installation of bifacial PV panels in Korea should primarily focus on southwest-to-west orientation. Furthermore, it was concluded that bifacial PV panels could contribute an equivalent or even superior level of energy production compared to single PV panels, even if their performance exhibited a marginally lower efficiency of 2% to 5% with an 18% power generation efficiency.
