本文提出了一种用于光伏 (PV) 面板的替代冷却技术，其中包括在面板表面喷水。一种替代冷却技术，即同时冷却光伏电池板的两侧，以研究在太阳辐照峰值水平的情况下总喷水冷却对光伏电池板性能的影响。详细阐述了具体的实验设置，并在典型地中海气候的地理位置对所开发的光伏电池板冷却系统进行了测试。实验结果表明，在太阳辐照峰值情况下，采用所提出的冷却技术可以实现发电量最大总增加16.3%（有效7.7%）和光伏电池板电效率总增加14.1%（有效5.9%）。此外，在同时进行正面和背面光伏电池板冷却的情况下，还可以将电池板温度从平均 54 °C（非冷却光伏电池板）降低至 24 °C。还确定了所提出的喷水冷却技术的经济可行性，其中所分析的冷却技术的主要优点在于光伏电池板的表面及其自清洁效果，这还可以作为平均输送电力的助推器。
This paper presents an alternative cooling technique for photovoltaic (PV) panels that includes a water spray application over panel surfaces. An alternative cooling technique in the sense that both sides of the PV panel were cooled simultaneously, to investigate the total water spray cooling effect on the PV panel performance in circumstances of peak solar irradiation levels. A specific experimental setup was elaborated in detail and the developed cooling system for the PV panel was tested in a geographical location with a typical Mediterranean climate. The experimental result shows that it is possible to achieve a maximal total increase of 16.3% (effective 7.7%) in electric power output and a total increase of 14.1% (effective 5.9%) in PV panel electrical efficiency by using the proposed cooling technique in circumstances of peak solar irradiation. Furthermore, it was also possible to decrease panel temperature from an average 54 °C (non-cooled PV panel) to 24 °C in the case of simultaneous front and backside PV panel cooling. Economic feasibility was also determined for of the proposed water spray cooling technique, where the main advantage of the analyzed cooling technique is regarding the PV panel’s surface and its self-cleaning effect, which additionally acts as a booster to the average delivered electricity.
