20.500.12556/RUL-177844 Experimental investigation of interconnection topologies for vehicle-integrated PV array Photovoltaic (PV) systems are increasingly popular because of decreasing prices and increasing efficiencies, enabling applications such as vehicle integrated photovoltaics (VIPVs) and building integrated photovoltaics (BIPVs). The performance of VIPVs is strongly affected by dynamic partial shading conditions due to vehicle movement in urban environments surrounded by buildings and trees. It is therefore important to develop technical solutions to optimize the performance of VIPVs by finding optimal electrical connections among cells to mitigate the shading effects and increase the power output. Building on previously published simulation analyses of Series-Parallel (SP), Total-Cross-Tied (TCT), Bridge Link (BL) and Honeycomb (HC) interconnection topologies, this paper presents a mathematical model and experimental comparative analysis using a PV array of 30 solar cells. The experiments are conducted using a flasher Spire Sun Simulator 5100 SLP emulating uniform solar irradiance under STC in addition to seven different partial shading scenarios. Experimental results show that the TCT interconnection outperforms the other interconnection schemes, delivering up to 21%, 8%, and 14% higher power output than SP, BL, and HC, respectively, under different shading scenarios. These results agree well with the simulation outcomes. dynamic partial shading conditions interconnection topologies photovoltaic power optimization vehicle-integrated photovoltaic systems dinamični pogoji delnega senčenja topologije povezav optimizacija fotovoltaične energije v vozila integrirani fotovoltaični sistemi true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-09 13:22:06 2026-01-09 13:22:06 2026-01-10 04:27:53 0000-00-00 00:00:00 2025 0 0 Str. 213416-213428 Vol. 13 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.38 2169-3536 10.1109/ACCESS.2025.3644180 262753795 Experimental_Investigation_of_Interconnection_Topologies_for_Vehicle-Integrated_PV_Array.pdf Experimental_Investigation_of_Interconnection_Topologies_for_Vehicle-Integrated_PV_Array.pdf 1 A6102EF965F69DD041D18708BBCA7F90 bf348ce4a151da79f894252c4c3cd6079ccc3d7b67fda46a1d00b54b65710e20 f5a8a027-ed55-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225205 https://ieeexplore.ieee.org/document/11299638 1 cdd57901-ed55-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225204 Fakulteta za elektrotehniko 0 0 0
