태양광 블라인드의 발전량 및 실내 조도 분석

Abstract

Zero-energy building (ZEB) certification is being increasingly adopted in response to climate change. However, achieving zero energy remains a significant challenge in apartment buildings, which typically have high energy demands. Conventional rooftop photovoltaic (PV) systems often face spatial constraints, highlighting the need for alternative solutions. Among the emerging PV technologies, PV blinds offer dual functionality: solar power generation and shading. However, prioritizing energy generation can compromise indoor lighting quality. This study investigated the impact of various PV blind parameters on both power output and indoor illuminance. The results show that, although increasing the installation area enhances total energy production, the power output per unit area tends to decrease owing to self-shading effects. Additionally, slat angles closer to perpendicular to the incident solar radiation improve both power generation and indoor illuminance, while contributing to a more uniform light distribution. These findings suggest that PV blinds have a strong potential for advancing the adoption of renewable energy in apartment buildings.
