Abstract

To limit climate change, the use of renewable energy is mandatory. PV/T systems generate renewable energy, simultaneously satisfy both the thermal and electrical energy requests. Usually, these systems have some limitations to fulfill the thermal energy needs; therefore, it is necessary to improve their efficiency with the aim to increase the enthalpy level of the energy produced. In this paper, the effects of changing the cooling fluid from pure water to a nanofluid composed by water and aluminum oxide (Al2O3) in a PV/T system are studied. The analysis is based on the thermodynamics viewpoint, considering both the total energy produced and its quality. The thermal level achievable by changing the heat transfer fluid, as well as the electrical efficiency considering various input conditions has been calculated. Finally, the energy yield produced by a conventional PV/T plant, which use pure water (PV/T)w and the proposed improved PV/T plant, which use pure the nanofluid (PV/T)nf, under real climate conditions have been compared. Such comparison was developed taking into account the second law of thermodynamics as well as the exergy analysis.
