Abstract
Solar photovoltaic/thermal technology has been widely used in private and commercial buildings because it produces heat and electricity simultaneously. To improve the performance of PV/T systems, nanofluids are used as potential heat transfer because of their high thermal conductivity. This paper summarizes the thermophysical properties of nanofluids (thermal conductivity, thermal diffusivity, viscosity, density and specific heat), the effect of fluid flow configuration (spiral, straight, mesh), cross-sectional shape (rectangle and circle) on PV/T performance, to the application of nanofluids as PV/T coolants. The heat transfer from the back of the PV module was shown to increase with the increasing concentration of nanoparticles in the base fluid. The performance of nanofluids is also at ambient temperature because it affects the viscosity. The PV/T power generated by the addition of nanofluid cooling increased by 6%. In addition, differences in fluid flow configuration, type of nanoparticles, size of nanoparticles and ambient conditions affect the performance of PV/T. The rectangular shape is able to increase the electrical efficiency by 11.4%, while the circular cross-section is 6%. These are some of the key parameters for using nanofluids as coolants to improve the performance of PV/T systems.
