(1)Techno-economic performance analysis of the smart solar photovoltaic blinds considering the photovoltaic panel type and the solar tracking method,by Hyuna Kang,Taehoon Hong,Seunghoon Jung,Minhyun Lee,Pages 1-14 Abstract: In urban areas with dense buildings,it is expected that the building-integrated photovoltaic (BIPV) system,will become widespread.Especially,the solar photovoltaic blinds (SPB),which can block the sunlight coming into the room and produce electricity,is emerging as a new technology trend.To facilitate the installation of the SPB,this study analyzed the techno-economic performance of the smart SPB considering the PV panel type and solar tracking method used.Towards this end,this study conducted experiments using the developed smart SPB,as well as a comparative analysis in terms of the techno-economic aspects based on the experiment results.The analysis results of this study were as follows: at the same cost,(i) the monocrystalline silicon (mono-Si) PV panel generated 350.5 % more electricity than the amorphous silicon (a-Si) PV panel;and (ii) the direct solar tracking system generated 12.9 % more electricity than the indirect solar tracking method.Accordingly,the mono-Si PV panel and the direct solar tracking method were selected for the optimal smart SPB.The installation of the smart SPB with the proposed optimal design on the south-facing window of buildings can be helpful for raising the electricity self-sufficiency rate of buildings by up to 20.3 %.
