Building integrated thin film photovoltaic performance modelling on conventional building

摘要

PV(Photovoltaic) technologies have been developed into many forms. The emergence of BIPV (Building Integrated Photovoltaics) technology, it is possible for a building component to have another function as an energy generator. The technology of thin film PV, can be used as glass in buildings. PV (Photovoltaics) thin films can be applied as windows glasses. For older or conventional buildings, it is necessary to modify the window to applying the BIPV system. To estimate the energy generated from the BIPV system, a study needs to be conducted. In this study case analysis, a BIPV will be applicate on conventional 4-storey office building. Simulation is done with SAM (System Advisor Model) software. For solar energy potential is obtained from PV GIS data. From the simulation, the 40% of transparency thin film PV that applied in conventional building has 6.8% of capacity factor and 9,761 kWh of energy generated in the first year. A single 0.72 m~2 CdTe thin film PV module can generate approximately 23.76-38.01 kWh/year. The thin film BIPV generation is very depending on PV shading, so it important to consider PV orientation and position.
