研究了光伏组件下方独特的聚乙烯换热器回路的集成。该系统被设计成一个屋顶元件，适当地融入周围环境，从而避免“附加”外观，并为太阳能辅助加热和冷却技术提供热源。一个详细的热模型是适应调查的屋顶单元的热性能。采用工程方程求解器（EES）对英国诺丁汉的气候条件和光伏屋顶集热器的设计参数进行了数值计算。实验结果表明，系统的水温差可达16 ° C，系统的热效率可达20.25%。进行能量和火用分析，以观察由于实施隐藏的热提取组件而增加的能量和火用效率。采用寿命周期成本法进行技术经济分析。评估表明，整个系统的估计年节能量为10.3 MWh/年，发电成本为每千瓦时0.0778欧元。
The integration of unique polyethylene heat exchanger loop underneath PV modules is studied. The system is designed to act as a roof element that properly blends into surroundings thus avoiding ‘add-on’ appearance and having a heat resource for solar assisted heating and cooling technologies. A detailed thermal model is adapted to investigate the thermal performance of the roof unit. Numerical computations have been carried out by using Engineering Equation Solver (EES) in terms of climate conditions of Nottingham, UK and design parameters of the building integrated PV/T roof collector. The experimental values indicate that water temperature difference could reach up to 16 °C, and the system would achieve up to 20.25% overall thermal efficiency. The energy and exergy analysis is performed to observe the increase in energy and exergy efficiencies due to the implementation of concealed heat extraction component. Techno-economic analysis is carried out by applying the Life Cycle Cost (LCC) method. Evaluations show that the estimated annual energy savings of the overall system is 10.3 MWh/year and the cost of power generation is found to be €0.0778 per kWh.
