옥외 실험을 통한 동·서향 양면 태양광발전 시스템의 발전성능 분석

The growing push to decarbonize the building sector has led to an increase in the adoption of new and renewable energy systems, notably expanding the market size of photovoltaic (PV) systems. However, this surge in PV deployment has resulted in power generation becoming concentrated in short periods, leading to unstable power system operations. To address this, East-West PV systems have emerged as a promising alternative due to their more consistent power generation throughout the day. In particular, the application of bifacial modules to East-West PV systems is gaining attention for its potential to enhance power output. Yet, research has been limited in analyzing the electrical performance of East-West oriented bifacial PV systems. This study investigated the peak generation distribution and electrical performance of East-West oriented PV systems, comparing them with South-oriented PV systems. The findings indicate that East-West oriented PV systems experience smaller daily power generation fluctuations compared to South-oriented systems, suggesting a reduced burden on the power grid. However, the total daily power generation of East-West oriented PV systems is 14.3% lower than that of South-oriented systems, highlighting the need for a comprehensive evaluation of this trade-off.
