摘要
设计搭建了一种V形槽式低倍聚光光伏光热一体化(PV/T)组件,将V形槽式聚光器与无空腔型PV/T组件结合起来。通过Trace Pro软件模拟发现,V形槽式低倍聚光PV/T系统单日制热量的增加百分比随安装角度的增大呈先增大后减小的趋势。当安装角度为23°时,增强作用最明显,聚光后光热转化功率能提高8.57%。实验结果表明,安装角度23°时总发电量比原来提高了19%。通过动态调整反光铝板安装角度,发现在太阳光照强度最强时V形槽安装角度在20°~30°之间移动时,整体的聚光效率最高。V形槽式低倍聚光PV/T组件的光伏光热效率均高于原有的无空腔PV/T组件和有空腔PV/T组件,具有较大的应用价值。
A v-type low-power PV/T( photovoltaic solar thermal integration) module is designed,which combines the v-type groove condenser with the empty cavity PV/T component. Through Trace Pro software simulation found that V groove type system of low power concentrated PV/T system daily caloric percentage increase along with the increase of the installation Angle of the first increases and then decreases trend,when installation Angle is about23°,the most obvious,enhance after concentrating solar-thermal conversion power can be increased by 8. 57%.The experimental results show that the installation Angle of 23° total generating capacity than the original increased by 19%; By dynamically adjust the Angle of reflective aluminum plate installation,found in the sun light intensity is strongest when V groove installation Angle between 20° to 30° moves the highest efficiency of concentrated as a whole. The PV photothermal efficiency of the v-type low-power PV/T component is higher than that of the original empty cavity PV/T component and the spare cavity PV/T component,which has great application value.
