As efficiency of PV modules decreases with temperature rise, cooling methods can increase the power output and efficiency. One of the strategies for this purpose is passive cooling by implementing fins to the backside of a module. In the present study, annual energy output of a 50 W panel is analytically calculated in two unfinned and pin-finned cases based on hourly meteorological data for Shiraz, Iran. The results show that with the installation of 2-cm, 4-cm and 6-cm aluminum pin fins with finned-to-total-backside-area ratios of 0.17, 0.27 and 0.55, the power output increases by 1.24–4.16%, compared to the unfinned case. This increase is equivalent to 1.04–3.50 kWh more electrical energy production during a year.

通过针翅提高光伏面板的性能:理论分析

由于光伏组件的效率随着温度的升高而降低,冷却方法可以提高功率输出和效率。为此目的的策略之一是通过在模块背面安装散热片来进行被动冷却。在本研究中,根据伊朗设拉子的每小时气象数据,在两个无鳍和有鳍的情况下,对 50 W 面板的年能量输出进行了分析计算。结果表明,安装 2 厘米、4 厘米和 6 厘米铝针翅片,翅片与总背面面积之比为 0.17、0.27 和 0.55,功率输出增加了 1.24-4.16%,与未决案件相比。这一增长相当于一年中电能产量增加 1.04-3.50 千瓦时。
