Application of building-integrated photovoltaic technology (BIPV) has developed rapidly in the world and the progress in Hong Kong is also encouraging in recent years. More than 1MWp of PV modules have been integrated in buildings in this small territory. The first BIPV system in Hong Kong has been working successfully for ten years. This paper presents our research findings of the BIPV applications in buildings for efficient use of solar energy. Various studies have been performed for maximum use of BIPV technologies including energy performance simulation and real BIPV project data monitoring. The heat and mass transfer of semi-transparent BIPV modules has been studied, and the shading effect of BIPV façade/arrays has been investigated. A detailed energy, economic and environmental analysis of a 4kW PV-roof project will be reported as a case study. The design and operation experience of this gridconnected BIPV system will be presented. Besides, the current BIPV application and its future potential in Hong Kong will be reported. Significant power from BIPV installations can be generated if good energy policy is adopted in this territory.
