Abstract

The photovoltaic-thermal (PV/T) integrated system efficiently utilizes solar energy by converting a portion of absorbed solar radiation into electricity while the rest is transformed into thermal energy and collected by heat transfer media. It is still very important to study more effective types of PV/T system to improve the overall performance of the system. This study proposes a novel vacuum-tube PV/T system with inserted PV module and heat pipe. The experimental platform of the novel PV/T system is built. The energy transfer model of the system is established, and the self-programmed code is adopted to solve the model. The performance including the energy, exergy, economic and environmental analyses of the novel PV/T system is evaluated through calculation and experimental measurement. The results indicate that the vacuum-tube PV/T system with inserted PV module and heat pipe effectively reduces temperature of photovoltaic cell, reduces heat loss, and improves the electrical efficiency, thermal efficiency, and overall efficiency. The highest electrical efficiency, thermal efficiency and overall efficiency of the system reaches 11.86 %, 60.66 % and 68.44 % respectively. The overall efficiency is higher than those of the traditional flat-plate PV/T system. These indicate that the novel system is feasible for practical application and promotion.
