Abstract

Even though the southeast region of Algeria, especially Ouargla city, enjoys a lot of sunshine all over the year, fixed photovoltaic (PV) solar panels are not sufficient due to two main reasons. Firstly, these panels are unable to capture sunlight during the early morning and late afternoon, and secondly, their efficiency is low, requiring the use of economical methods to enhance their performance. To overcome these limitations, this research suggests incorporating commercial reflectors to enhance sunlight capture. Furthermore, this paper compares the effects of three types of reflective materials: mirrors, aluminium, and transparent glass, on the performance of the PV module. To achieve this objective, reflectors are installed at the top and bottom of the PV module at their optimal tilt angles. Moreover, the effect of the adjacent module's mirrors was studied by installing two big mirrors (3X). The obtained results show an average improvement of 14.24 %, 11.41 %, and 4.7 % in the electrical energy generated by the PV panel with mirrors, aluminium, and transparent glass, respectively, compared to the module without reflectors. Subsequently, in the large mirror case, the results were positive, with an average 20.84 % increase in the maximal electrical power produced compared to the conventional one.

在阿尔及利亚南部使用商业反射器增强光伏组件：不同反射材料之间的比较

尽管阿尔及利亚东南部地区，特别是瓦尔格拉市，全年日照充足，但由于两个主要原因，固定式光伏太阳能电池板并不充足。首先，这些太阳能电池板无法在清晨和傍晚捕捉阳光；其次，它们的效率较低，需要使用经济的方法来提高其性能。为了克服这些局限性，本研究建议采用商业反射器来增强对阳光的捕捉。此外，本文还比较了三种反光材料（镜面、铝和透明玻璃）对光伏组件性能的影响。为实现这一目标，在光伏组件的顶部和底部以最佳倾斜角度安装了反射器。此外，还通过安装两个大反射镜（3 倍）研究了相邻模块反射镜的影响。结果显示，与不带反射镜的模块相比，带反射镜、铝和透明玻璃的光伏板产生的电能分别平均提高了 14.24%、11.41% 和 4.7%。随后，在大型反射镜的情况下，结果也是积极的，与传统的反射镜相比，产生的最大电能平均增加了 20.84%。

期刊介绍： The main goal of this journal is the enhancement of academic activities of IMEKO and a wider dissemination of scientific output from IMEKO TC events. High-quality papers presented at IMEKO conferences, workshops or congresses are seleted by the event organizers and the authors are invited to publish an enhanced version of their paper in this journal. The journal also publishes scientific articles on measurement and instrumentation not related to an IMEKO event.
