“…A linear correlation between PM 10 and the soiling accumulation rate (in grams of particulate accumulated on 1.0 m 2 of PV cover plate per day) was first presented in Ref. [33], where two sites in Colorado were investigated. In the previous communication [12], it was found that, among the investigated parameters, PM 10 and PM 2.5 had better correlations with soiling losses than any other parameter.…”

One hundred and two environmental and meteorological parameters have been investigated and compared with the performance of 20 soiling stations installed in the USA, in order to determine their ability to predict the soiling losses occurring on PV systems. The results of this investigation showed that the annual average of the daily mean particulate matter values recorded by monitoring stations deployed near the PV systems are the best soiling predictors, with coefficients of determination (R 2 ) as high as 0.82. The precipitation pattern was also found to be relevant: among the different meteorological parameters, the average length of dry periods had the best correlation with the soiling ratio. A preliminary investigation of two-variable regressions was attempted and resulted in an adjusted R 2 of 0.90 when a combination of PM 2.5 and a binary classification for the average length of the dry period was introduced.

Soiling is the process whereby dirt, dust, and organic/inorganic contaminants deposit on the surface of a photovoltaic (PV) module. It causes significant economic losses and can have a substantial impact on the expansion of photovoltaic technologies for energy generation. The first step to address soiling adequately is monitoring, as soiling mitigation has to be tailored to the specific conditions of each PV system and no universally valid strategy exists. The main focus of this study is to assess the current state of the art in soiling monitoring, in order to help the community better understand the needs and the challenges in this area. The potentials and the limitations of each monitoring method are discussed thoroughly in the paper, with the support of original experimental data. An estimation of the future soiling monitoring market trends is also presented, with a forecasted need for tens of thousands of new soiling monitors every year.

“…If PV performance and soiling data are lacking, environmental parameters could ideally be used to predict soiling at a new PV site because they are available for multiple years in many locations at no additional hardware cost. When the project started, studies had already discussed the relations between soiling, rainfall, and particulate matter; 6,20 but no work had moved beyond site-specific soiling-loss analysis, investigating these relations in a systematic way for a large number of sites.…”
