太阳能光伏光热一体化不仅可以有效降低电池组件温度,提高光伏发电效率,且能产生热能,从而大大提高太阳能的综合利用效率。介绍了一种新型的基于平板微热管阵列的太阳能光伏光热(PV/T)集热器,并进行了性能测试。结果表明,在秋冬过渡季节,系统的太阳能综合利用效率能达到40%左右,对光伏建筑一体化具有参考价值。
Solar photovoltaic solar thermal integration can not only effectively reduce the temperature of the battery pack, improve the efficiency of photovoltaic power generation, and can generate heat, thus greatly improving the comprehensive utilization of solar energy efficiency. A new type of solar photovoltaic solar thermal collector (PV / T) based on planar micro heat pipe array is introduced and its performance is tested. The results show that in the autumn and winter transitional season, the solar energy utilization efficiency of the system can reach about 40%, which is of reference value to the integration of photovoltaic buildings.
