Deployment of solar photovoltaic panels are significantly rising to tackle adverse effects of climate change however, factors affecting output need to be categorized in addition to latitude angle and space. It is important to consider the atmospheric impact which can drastically change output power of solar panels. This study covers dust accumulation of soil, sand and ash at variable weights to foresee its effects on panel power output. Mixtures of these particles at multiple constituents were also analyzed. Experimental results indicated that clean panel gives maximum power output of 21.37W and exergy efficiency of 7.96% whereas ash accumulation showed worst results of 2.88W power output and 1.07% exergy efficiency at 700W/m2 and 50g dust accumulation. Other parameters like energy destruction, exergy losses and sustainability index were also analyzed. Trends have been illustrated in graphs along with the change in solar intensity and dust accumulations.
太阳能光伏电池板的部署正在大幅增加，以应对气候变化的不利影响，然而，除了纬度角和空间之外，还需要对影响输出的因素进行分类。重要的是要考虑大气影响，因为大气影响会极大地改变太阳能电池板的输出功率。本研究涵盖了土壤、沙子和灰烬的积尘，以预测其对面板功率输出的影响。还分析了这些颗粒在多种成分下的混合物。实验结果表明，清洁面板的最大功率输出为 21.37W，火用效率为 7.96%，而在 700W/m2 和 50g 灰尘积累的情况下，积灰显示出最差的结果，功率输出为 2.88W，火用效率为 1.07%。还分析了其他参数，如能量破坏、火用损失和可持续性指数。还沿着太阳强度和灰尘积累的变化以图表形式说明了趋势。
