Abstract
In order to study the operational performance of the trapezoidal cross section micro heat pipe photovoltaic-thermal integrated module (MHP-PV/T) in series during winter, six sets of MHP-PV/T modules with trapezoidal cross section are selected for experimental research. The photovoltaic, photothermal, and comprehensive performances of the system are analyzed. The experimental conclusions show that under the conditions of an average solar irradiance of 692.4 W/m2 and an outdoor ambient temperature of 3.3 ℃, the average photovoltaic power of six groups of trapezoidal overcurrent cross sections MHP-PV/T in series is 719.5 W, photovoltaic efficiency is 10.8%, power generation is 5.76 kW·h, photothermal power is 2088.3 W, photothermal efficiency is 24.0%, effective cumulative heat is 9.40 kW·h, total energy power is 2988.0 W, and total energy efficiency is 35.8%. The research results indicate that the series-connected MHP-PV/T modules with trapezoidal cross-section has good photovoltaic and photothermal performance, which provides reference value for the further development and application of MHP-PV/T.
