Performance Enhancement of Solar Photovoltaic Thermal Energy Collection (PV/T) System with W-Shaped Rib Rouhgness

The purpose of this study is to investigate the possibility improving electrical (cell) efficiency, thermal and overall performance by adding w-rib roughness bottom absorber plate. plate being given roughness. Based on a mathematical simulation PV/T system as function pertinent geometrical parameters, such relative pitch, height, angle attack, well design temperature rise insolation, parameters—enhancement performance—have been assessed. was examined using in relation important factors. results show that adopting yields significant improvement over metrics obtained smooth plates.
