| 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 selfsufficiency rate of buildings by up to 20. 3%. |
