A building-integrated photovoltaic (BIPV) system is a renewable energy system that generates electricity and functions as a building envelope for zero energy buildings (ZEBs). BIPV can be applied to roofs, façades, and window systems. In particular, a semi-transparent BIPV applied to window systems is designed to satisfy the thermal performance requirements of national standards. The solar heat gain coefficient (SHGC) is used to estimate the solar radiation that passes through the glass relative to the amount of solar radiation hitting the glass. The SHGC of a semitransparent BIPV system change with the PV cell ratio, design, and electrical performance of the system. However, studies on the performance evaluation of SHGC for semitransparent BIPV systems are scarce. In this study, a method for evaluating the SHGC of a semitransparent BIPV system was investigated. The results indicate that SHGC values for the semi-transparent BIPV system should be studied for different operating conditions as indicated by maximum power point (MPP) and open circuit (OC) values. This is because the SHGC of the system changes with the power generation of the PV cells.
Abstract
A building-integrated photovoltaic (BIPV) system is a renewable energy system that generates electricity and functions as a building envelope for zero energy buildings (ZEBs). BIPV can be applied to roofs, façades, and window systems. In particular, a semi-transparent BIPV applied to window systems is designed to satisfy the thermal performance requirements of national standards. The solar heat gain coefficient (SHGC) is used to estimate the solar radiation that passes through the glass relative to the amount of solar radiation hitting the glass. The SHGC of a semitransparent BIPV system change with the PV cell ratio, design, and electrical performance of the system. However, studies on the performance evaluation of SHGC for semitransparent BIPV systems are scarce. In this study, a method for evaluating the SHGC of a semitransparent BIPV system was investigated. The results indicate that SHGC values for the semi-transparent BIPV system should be studied for different operating conditions as indicated by maximum power point (MPP) and open circuit (OC) values. This is because the SHGC of the system changes with the power generation of the PV cells.
