本文首先利用一个非稳态传热模型对同一环境条件下光伏光热一体化(PV/T)系统、光伏系统(PV)和太阳能热水器的能效进行分析,然后采用层次分析法(AHP)对不同品质终端能源输出的太阳能利用系统的能效统一表征,并以北京、广州和银川为代表的不同城市自然环境及用电价格为条件的三种情景,对三种太阳能利用系统的综合能源利用效率、累计净收益和投资回收期进行分析。结果表明,太阳能利用系统的经济性不仅受到系统能源利用效率和成本的影响,系统所在地的自然环境和电价水平也会引起系统经济性发生变化,因此考虑多种因素的综合评价可以为太阳能技术推广提供更客观和准确的参考。

In this paper, an unsteady heat transfer model was established to simulate the energy efficiency of different solar systems such as solar photovoltaic-thermal (PV/T) system, photovoltaic (PV) system and solar water heater system under different climate conditions. The Analytic Hierarchy Process (AHP) method was then used to make a comprehensive analysis about the accumulated net income and payback period of these solar systems on equal terms, by using the results of the heat transfer model under three different electricity price in Beijing, Guangzhou and Yinchuan. Results showed that the economy of solar systems is not only interacted by cost and efficiency, but also by natural environment and electricity price. Under consideration with multi-elements, the evaluation may provide reference for the solar technology application.
