Abstract

Energy conversion efficiency of solar photovoltaic (PV) panels decreases with an increase in their surface temperature. Hence, cooling down the surface temperature is the most attractive method to enhance its performance. This paper presents an experimental study of the water-cooling front surface of a PV panel to increase the efficiency of solar energy conversion to electricity. Two panels of mono-crystalline type with 50 Wp of each panel are used for a non-cooled and cooled cases in this study. The experiment is conducted during the days of April 2022, in Sisattanark district, Vientiane Capital, Lao PDR. Results revealed that the cooled panel has got better performance than the non-cooled panel. This is confirmed by exergy analysis that the average exergy efficiency is 2.91 % and 12.76 % for the non-cooled and cooled panels, respectively. In conclusion, the water-cooling solar PV panel enables the improvement of electrical characteristics generated thus, enhancing the efficiency of the panel.

水冷太阳能光伏板性能改进及火用分析

太阳能光伏板的能量转换效率随着其表面温度的升高而降低。因此，降低表面温度是提高其性能的最有吸引力的方法。为了提高太阳能转化为电能的效率，本文对光伏板的水冷前表面进行了实验研究。在本研究中，非冷却和冷却的情况下使用了两个单晶型面板，每个面板50 Wp。实验于2022年4月在老挝人民民主共和国万象首都Sisattanark区进行。结果表明，冷却板的性能优于非冷却板。经火用分析证实，非冷却板和冷却板的平均火用效率分别为2.91%和12.76%。综上所述，水冷太阳能光伏板能够改善产生的电气特性，从而提高面板的效率。
