Experimental Study to Improve the Exergy Performance of Water Based Photovoltaic Thermal Collector (PV/T System) Using Water Guides

Abstract

Photovoltaic panels can convert solar irradiance into (electrical and thermal) energy. The PV / T system was developed, created, and its performance tested in this experimental analysis. The experiment was performed with a flow rate of water from 1 L / min to 5 L / min on the PV / T collector channel. The movement of water with the guides allows the PV / T collector to improve thermal heat transfer convection. The output of (electrical and thermal) energy increase with the increase in radiation. The PV / T system performance varies with different volume flow rate that was reported for (1-5) L/min in this experiment, where the total energy increase with increasing the flow rate. Energy and exergy tests are performed, and findings show the maximum electrical and thermal energy output for a water-based PV / T system is 58.38 W and 465.8W at solar radiation 1000 W/m². Meanwhile the maximum electrical and thermal efficiency of PVT systems is 14.595%, 94.49 % respectively at 5 LPM. While the maximum electrical percentage improvement in PV / T systems electrical output by the use of guides device is (36.78%), compared with traditional PV module.
