Abstract

Serpentine pipeline water-cooled PV/T module was proposed. The comparison experiments were conducted on the experimental platform of dual-heat source quadruple power supply system, where the effect of different inlet water temperatures of the serpentine pipeline water-cooled PV/T module on the electrical and thermal efficiency can be investigated. The results show that： The inlet water temperature shows a positive linear correlation with the temperature of the photovoltaic module and a negative linear correlation with the heat gain. Compared with the comparison module, the temperature of the water-cooled PV/T module can be decreased by 21.19 ℃-31.74 ℃, and the electrical efficiency is increased by 6.838%-11.805%. For every 5 ℃ decrease in inlet water temperature, the electrical efficiency is increased by 2.5%-5%, and the thermal efficiency is increased by 9.28%-29.32%. With the average solar irradiance of 600 W/m², serpentine pipe flow rate of 0.30 m³/h and the average ambient temperature of 36.3 ℃, the electrical efficiency of serpentine water-cooled PVT module is 17.90%, the thermal efficiency is 65.70%, and the comprehensive efficiency can reach 112.80% when the inlet water temp
