Abstract

This paper proposes and builds a novel type of high concentration photovoltaic/thermal(HPV/T)system, combines the Fresnel type point-focus photovoltaic system with PV/T system effectively, and carries on the experimental study. Through outdoor test and analysis of data, the result showed that direct current rises with the rise of direct irradiation. At first, when the tank temperature is low, there is little fluctuation on the output direct voltage. When the temperature in water tank is too high, the output of direct voltage rises slowly. The peak power can reach 12.10 kWh. From 09: 40 to17: 00, power generating capacity is 77 kWh in this system. The highest instantaneous electrical efficiency is as high as 28.9%, and the average electrical efficiency is 27.36%. The highest instantaneous thermal efficiency is more than 33.54%, and the average thermal efficiency is 30.02%. The overall efficiency of the system is more than 60.00%.
