Abstract: Energy performances of a photovoltaic thermal plant using different coolant nanofluid

In the last four decades, greater attention has been paid to PV/T systems due to their advantages compared with PV or solar thermal systems alone. Recently, nanofluids have been implemented as heat transfer fluids in PV/T systems. The thermal properties of several investigated water nano-fluids are derived from literature data. In particular Al2O3– water (1–4% particle volume fraction) and TiO2–water (1–6% particle volume fraction) water nano-fluids, as well as ZnO-EG at different volume fractions are investigated in this study.
The performance of the different nano-fluid PVT plant are simulated through” TRNSYS” software. First, several limitations and constraints needed to be resolved to develop a trustworthy simulation environmentwithin the TRNSYS framework. In particular, the great sensitivity to particle volume fraction and temperature of the thermal conductivity of the nanofluid has to be taken into account. Thermal and electrical efficiency as well as the energy yields by changing the heat transfer fluid, considering variable weather conditions are calculated. The achieved results showed the positive contribution of the implementation of nanofluid in PVT plant.
