Abstract Photovoltaic/thermal (PV/T) technologies are used to comprehensively utilize photovoltaic and solar thermal, among which concentrating PV/T technology can enhance the performance of a PV/T system. To analyze the performance of a LCPV/T system with a geometric concentration ratio of 4, the LCPV/T system and a conventional flat-plate PV/T system were fabricated and experimentally studied under a constant flow rate condition. The results show that the electrical power and thermal power of the LCPV/T system were 3 and 1.9–2 times more than those of the flat-plate system. The comparative experimental study indicates that the electrical performance of LCPV/T system is significantly greater than the flat-plate system, and the thermal performance of LCPV/T system slightly improved and should be optimized because of the heat transfer factor.
