Energy and Exergy evaluation of Photovoltaic Thermal (PVT) system cooled by nanofluid and Spiral Flow Absorber.
… ow rates ranging from 0.011 kg/s to 0.033 kg/s and a solar irradiance of from 250 to 1000 W/m². Recently, exergy analysis has been applied to evaluate PVT collector performance more comprehensively. In the study, the analyses show that the PVT exergy efficiency is between 22% and 40% with thermal exergy of 572 to 118 W …
