Abstract

This paper studies the performance of a dual-channel PV/T system with water as working fluid. The optical properties of water were characterized, and we built a laboratory experiment setup to conduct experimental research on the performance of the dual-channel PV/T system under laboratory conditions. Effects of different flow rates and with or without a phase change material layer on the performance of the system were investigated, including the impact on the working temperature of sdar cells and the electric and thermal efficiencies of the system. The experiment results show that the dual-channel PV/T system can effectively reduce working temperature of sdar cells. When the flow rate of working fluid increases from 100 mL/min to 300 mL/min, the average temperature of sdar cells of the dual-channel PV/T system decreases by 1.77 ℃, and the electric and thermal efficiencies increase by 0.09% and 4.11%, respectively. Compared with the electric performance, changes in flow rate have a greater impact on the thermal performance of the system. The dual-channel PV/T system with phase change materials further reduces the operating temperature of the solar sdar cells. The electric and thermal efficiencies of the system are improved, and the system can reach a higher overall conversion efficiency.
