Abstract

This study investigates the impact of cooling methods on the electrical efficiency of photovoltaic panels (PVs). The efficiency of four cooling techniques is experimentally analyzed. The most effective approach is identified as water-spray cooling on the front surface of PVs, which increases efficiency by 3.9% compared to the case without cooling. The results show that water-spray cooling raises the PV's temperature to 41°C, while improving its average daytime efficiency to 22%. Air-cooling, water-cooling in the tubes behind the PV, and aluminum oxide-water nanofluid cooling in the tubes behind the PV improve efficiency by 1.1%, 1.9%, and 2.7%, respectively. The findings highlight the potential of water-spray cooling as a cost-effective and efficient method to enhance PV efficiency and contribute to the global effort towards renewable energy.

摘要

本研究调查了冷却方法对光伏板（PV）电效率的影响。对四种冷却技术的效率进行了实验分析。最有效的方法被确定为在光伏板前表面进行喷水冷却，与无冷却情况相比，效率提高了3.9%。结果表明，喷水冷却将光伏板温度升至41°C，同时将其白天平均效率提高到22%。风冷、光伏板后方管内水冷以及光伏板后方管内氧化铝-水纳米流体冷却分别将效率提高了1.1%、1.9%和2.7%。研究结果突出了喷水冷却作为一种经济高效的方法来提高光伏效率的潜力，并为全球可再生能源的努力做出贡献。
