Solar photovoltaic installations have now become a common sight across the globe. However, in places with a high level of dust, the panels have not performed as expected. The dust deposition acts to reduce the effective light that the solar cells receive thus reducing the output. As such, cleaning regimes are instituted to improve the performance of the panels. The more often the cleaning, the better the performance, but this could likely imply more energy is used for cleaning and the improvement may not be sufficient. In this paper, we develop a model to forecast the output power with respect to variables of cleaning, wind, humidity and temperature. The result shows that it is possible to develop a model to optimise cleaning regimes taking into account meteorological factors. One has to consider the impact of wind, which was found to be positively correlated with photovoltaic power output.

太阳能和沙子:减少沙漠中光伏阵列的灰尘沉积
太阳能光伏装置现已成为全球常见的景象。但是,在灰尘较多的地方,面板的性能不如预期。灰尘沉积的作用是减少太阳能电池接收的有效光,从而降低输出。因此,制定清洁制度以提高面板的性能。清洁越频繁,性能越好,但这可能意味着更多的能量用于清洁,而改进可能还不够。在本文中,我们开发了一个模型来预测与清洁、风、湿度和温度等变量相关的输出功率。结果表明,可以开发一个模型来优化清洁制度,同时考虑到气象因素。必须考虑风的影响,
