摘要

为探究太阳能光伏光热一体化（PV/T）系统在太阳能资源相对贫乏地区应用时的性能

在重庆市长寿区搭建PV/T系统实验平台并展开研究。实验结果表明：PV/T系统在夏季和冬季均表现出良好的发电性能

日平均发电效率分别为14.08%、14.59%;夏季日平均热效率可达35.47%

单日收集的热量可使1 m3水箱内的水温提升22.0 ℃;冬季日平均热效率较低

仅为12.41%。采用敏感性分析方法对比太阳辐照度、冷却水温度、环境温度3个因素对系统发电性能的影响程度

三者的敏感性系数分别为110.15、20.09、5.60

系统对太阳辐照度的敏感性最高。

Abstract

In order to explore the performance of solar photovoltaic thermal （PV/T） system in the area of relatively poor solar energy resources

we set up a PV/T system experimental platform in Changshou District of Chongqing and carried out the research. The experimental results indicate that： The PV/T system exhibits merit power generation performance in summer and winter

with daily average power generation efficiencies of 14.08% and 14.59%

respectively. The average daily thermal efficiency in summer can reach 35.47%

and the heat collected in a single day makes the water temperature in the 1 m tank rise by 22.0 ℃; The average daily thermal efficiency in winter is 12.41%. Use the sensitivity analysis method to compare the impact degree of solar irradiance

cooling water temperature and ambient temperature on the power generation performance of the system. The sensitivity coefficients of the three factors are 110.15

20.09

and 5.60

respectively

and the system has the highest sensitivity to solar irradiance This study provides reference for the application of PV/T system in Chongqing and other areas with relatively poor solar energy resources.
