Using The Low Concentrated Photovoltaic Module As A Preheater In An Organic Rankine Cycle

I n concentrated photovoltaic thermal CPVT systems, sunlight is directly converted into electricity and during this conversion waste heat is generated on the photovoltaic module. The resulting waste heat can be used for heating the fluids. In this study, the effect of using a low concentrating photo...

Summary:I n concentrated photovoltaic thermal CPVT systems, sunlight is directly converted into electricity and during this conversion waste heat is generated on the photovoltaic module. The resulting waste heat can be used for heating the fluids. In this study, the effect of using a low concentrating photovoltaic thermal system as a pre-heater before the evaporator in the organic Rankine cycle ORC was investigated. Thermodynamic analyzes were performed for different solar radiation values, concentration ratio values and various photovoltaic module PV materials. The increase in solar radiation and concentration increased the electricity production in the photovoltaic module and the thermal efficiency of the system but led to a decrease in exergy efficiency. In the analyzes, four different PV module materials were examined and M-Si and P-Si module materials showed better performance in terms of system efficiency and electricity production
