In order to improve the efficiency of solar energy utilization, a hybrid concentrated photovoltaic/thermal(CPV/T) system equipped with 750× Fresnel lens and roll-bond heat collector of water-bifurcated channel was proposed. The system produces both electricity and heat performance of the system was tested based on the outdoor measurement in a clear day. The experimental results show that the maximum generating power of the system can reach 3.656KW, with an average generating power of 3.31KW. The total generating energy of the system reached 25.21KWh from 9:00 am to 5:00 pm. The maximum and average electrical efficiency are 25.36% and 24.53%, respectively. The maximum and average thermal efficiency are 63.92% and 58.72%, respectively. The total efficiency can be more than 80%.
