In Turkey, Southeastern Anatolia region is the highest in terms of solar radiation level. However, the provinces in the region are subject to Particulate Matter (PM) coming from the Sahara desert, the Syrian Desert and the Arabian Desert by atmospheric transport. The daily limit of PM₁₀ and PM_2.5 set by WHO for health is often exceeded in Sanliurfa. PM₁₀ and PM_2.5 pollutants also accumulate on the Photovoltaic (PV) panels and cause loss of PV panel performance. In this study, the effects of atmospheric dust deposition on the performance of PV panel was determined for both monocrystalline and polycrystalline technologies under Sanliurfa atmospheric conditions. Two panels with the same characteristics were used for each PV panel group from 2 different PV technologies. One of the panels in the group was cleaned by washing with distilled water every Monday while the other was not cleaned. Thus, the effect of the dust accumulation on the PV panel was determined by comparison to the cleaned PV panel. PV panel power is measured with I–V meter. Panel surface temperature, solar radiation and other meteorological parameters are measured simultaneously. The measurements were done every Monday, Wednesday and Friday at 12:00 am from May 1 to December 31, 2019. It is observed that the dust accumulation reduces the PV power output up to 8% depending on the amount of radiation. During the summer months, the power loss on the average is 4.33% for monocrystalline and 4.57% for polycrystalline. In the autumn months, it is less than 1.77%.

在土耳其，安纳托利亚东南部地区的太阳辐射水平最高。但是，该地区的省份通过大气运输来自撒哈拉沙漠，叙利亚沙漠和阿拉伯沙漠的颗粒物（PM）。桑尼乌法经常超过世界卫生组织为健康设定的每日PM ₁₀和PM _2.5限量。PM ₁₀和PM _2.5污染物还会积聚在光伏（PV）面板上，并导致PV面板性能下降。在这项研究中，确定了Sanliurfa大气条件下单晶和多晶技术中大气粉尘沉积对PV面板性能的影响。来自2种不同PV技术的每个PV面板组使用具有相同特性的两个面板。该组中的一块板每个星期一都用蒸馏水清洗，而另一块板则没有清洗。因此，通过与清洁的PV面板比较来确定灰尘堆积在PV面板上的影响。光伏板功率使用I–V表测量。同时测量面板表面温度，太阳辐射和其他气象参数。每周一进行测量，从2019年5月1日到12月31日，在星期三和星期五的凌晨12:00。可以看到，灰尘的积累使PV功率输出最多降低8％，具体取决于辐射量。在夏季，单晶平均功耗为4.33％，多晶平均为4.57％。在秋季月份，该比例低于1.77％。
