Thermodynamic and thermoeconomic analysis of the concentrating photovoltaic thermal (CPV/T) solar collector integrated with kalina cycle

The usage of power cycles integrated with solar panels has increased considerably in recent years. In this study, the thermodynamic and thermoeconomic analysis of the Kalina cycle with parabolic trough type concentrated photovoltaic solar collector was investigated. One-dimensional thermal resistance networks were used to calculate the photovoltaic solar panel and thermodynamic equations were used to calculate the Kalina cycle. Power obtained from the turbine, power obtained from the panel, thermal and exergy efficiencies, panel temperature, net power produced, leveled electricity cost (LCOE), and payback time were determined as system outputs. These parameters were investigated depending on the variation of the inlet pressure turbine, concentration ratio, photovoltaic panel surface area, turbine isentropic efficiency, and variable radiation amounts parameters. The parameter that most affects the 1st law efficiency was the amount of solar radiation and the concentration ratio. It has been observed that the first law efficiency is 17.8% for the solar radiation amount parameter and 17.5% for the concentration ratio parameter. Also, it was observed that the 2nd law efficiency was 19% maximum for the solar radiation amount parameter and 19.5% for the concentration ratio parameter. It was determined that the most dominant parameter affecting the total electrical power produced in the system was the concentration ratio with a 44% increase. When the results were examined, it has been observed that approximately 28.5 kW of total power is produced from the current system under optimum conditions and approximately 21vii kW of this power was obtained from the solar panel. Another result is that this system, which has a facility life of 20 years, has a payback period of approximately 3 years. This has shown that a significant gain will be achieved in 20 years.
