Abstract

The high energy costs and environmental factors in energy systems cause pushed researchers to produce both heat and electricity from a single collector. In this context sustainable solar photovoltaic thermal energy system stand out with cleaner heat and electricity production at the same time. In this study, a new type of finned air fluid photovoltaic-thermal collector was designed, manufactured and tested. Numerical and experimental analysis were performed with different mass flow rates. Numerical analysis of the PV/T design was carried out before the experiments were conducted. ANSYS program was used to predict the surface temperature of PV module based numerical simulations validation ensures good agreement between the numerical and experimental results. In this way, the energy efficiency of the collector and the temperature of the outlet hot air were wanted to be estimated without experiment. The experiments were performed in two different mass flow rates [m(a) = 0.031087 kg/s and m(b) = 0.04553 kg/s] under similar meteorological conditions by investigating the effect of cooling on the PV module. Thanks to cooling of PV, 0.42% improvement in electrical efficiency was achieved. Energy and exergy analyses were performed to analyze the thermal and electrical efficiency of the PV/T collector. Thanks to the cooling of the PV panel, electrical efficiency increased by 0.42%. The average thermal and electrical efficiency of PV/T were obtained as for m(a) = 0.031087 kg/s 37.10% and 13.56% and for m(b) = 0.04553 kg/s 49.5% and 13.98%, respectively.

This study offers an efficient solution to numerical and experimental aspects air cooled PV/T for industrial producers with energy and exergy perspective. (C) 2020 Elsevier Ltd. All rights reserved.
