Research on impact of photovoltaic curtain walls on building optoelectronic performance—A case of a tourism and vacation complex
摘要：
透光光伏幕墙具有发电和室内采光2种功能,其应用于建筑中具有良好的节能效果。以文昌市某旅游度假综合体的建筑立面光伏幕墙为研究对象,测试其在典型气象日的发电和透光性能,以评估建筑立面光伏幕墙的综合节电效果。结果表明:高且稳定的太阳辐照度对光伏幕墙发电性能和照明节能性能均有积极的影响;对于采用50%透光碲化镉薄膜光伏玻璃的光伏幕墙,晴天、多云和阴天的平均发电效率分别为13.98%、9.24%和11.62%,光伏逆变器效率分别为96.08%、94.54%和94.15%,日间照明可节约等效电量分别为5.17、2.17、0.70 kW·h,发电量和照明可节约电量分别为9.12、3.10、1.15 kW·h。
Abstract：
The good energy-saving effect of the transparent photovoltaic(PV) curtain wall has been demonstrated due to its two functions of power generation and indoor lighting in buildings. The PV curtain wall of the building facade of a tourism and vacation complex in Wenchang is taken as the research object, and it is tested for power generation and light transmission performance on typical weather days to evaluate the comprehensive power-saving effect of the PV curtain wall of the building facade. The results show that high and stable solar irradiance has a positive impact on the power generation performance and lighting energy-saving performance of the PV curtain wall. For the PV curtain wall using 50% transparent CdTe thin-film photovoltaic glass, the average power generation efficiency on sunny, cloudy and overcast days is 13.98%, 9.24% and 11.62%, the efficiency of photovoltaic inverter is 96.08%, 94.54% and 94.15%, the equivalent electricity can be saved by daytime lighting is 5.17, 2.17 and 0.70 kWh, and the power generation and lighting can be saved by 9.12, 3.10 and 1.15 kWh, respectively.
