Study on effect of cooling fins on energy performance of photovoltaic panel

研究了被动式冷却条件下肋片对光伏板发电性能的影响,分析了光伏板倾角、太阳辐射强度、环境温度和风速等因素对光伏板发电效率和发电功率的影响规律,对带冷却肋片和不带冷却肋片的光伏板进行了实验对比。研究结果表明,在实验条件下,安装冷却肋片可以使光伏板的发电效率提高0.3%~1.8%,发电功率提高1.8%~11.8%。

The performance improvement of PV panel with passive fin cooling was studied under natural ventilation.A comparative experimental study on PV panels with and without fin cooling was carried out to investigate the effect of PV panel inclination, solar radiation, and ambient temperature as well as wind velocity on the electrical efficiency and power output.The results showed the average electrical efficiency of PV panel with fins was 0.3%~1.8% higher than that of PV panel without fins and the average power output of PV panel with fins was 1.8%~11.8% higher as well under various conditions in this study.
