| Abstract: | A mathematical model describing the energy flow process of the thermal pipe photovoltaic photothermal (PV&T) system was established. In order to study the influence of main parameters on system performance and reach the optimal value of system efficiency. The system was optimized by using photovoltaic efficiency and photothermal efficiency as the optimization index. The influence of the main parameters of the system (the number of collector tubes and the angle of collector inclination) on the photovoltaic efficiency and photothermal efficiency of the system is analyzed.The highest photothermal efficiency and photovoltaic efficiency of the thermal pipe PV&T system in the spring equinox, summer solstice, autumn, and winter solstice were determined, and the optimal collector heat pipe number and collector inclination angle corresponding to the system were determined. |
