12 In this paper we present a dynamic model of a hybrid photovoltaic/thermal (PVT) collector with a sheet-and-tube 13 thermal absorber. The model is used in order to evaluate the annual generation of electrical energy along with the 14 provision of domestic hot-water (DHW) from the thermal energy output, by using real climate-data at high 15 temporal resolution. The model considers the effect o...

Photovoltaic/thermal systems are one of the most efficient types solar collectors because they absorb radiation and generate electricity heat simultaneously. For first time, this paper presents an investigation into impact red wine-rGO/H2O nanofluid paraffin wax on thermohydraulic properties a photovoltaic/thermal system. The study focuses three innovative nonlinear arrangements serpentine tube...

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...

Renewable energy applications are lucrative alternatives to minimize urban environmental impacts. Solar energy, the most abundant, inexhaustible, and cleanest of all renewable sources, provides an opportunity transform buildings from consumers into active producers. Nevertheless, photovoltaic (PV) hybrid photovoltaic/thermal (PV/T) considered viable for settlements. This study, as part a broade...
