The natural soiling of photovoltaic cover glass has recently been shown to include both an inorganic and organic particulate matter. Under favorable growth conditions, the latter can lead dense colonies filamentous fungi, which potentially leads measurable performance losses over time. Herein, we report on a field study where coupon samples were deployed in soiling-prone locations, focused Dubai (United Arab Emirates) Mumbai (India). For each site location, clear differences observed. from...
Ambient particulate matter in urban environments is dynamic and heterogeneous; therefore, understanding photovoltaic energy loss due to soiling challenging. Silicon reference cells were deployed an urban-industrial area Colorado colocated with measurements of ambient concentrations. Regressing measured ratios against cumulative sums coarse since the last precipitation event fine first day deployment produces a root-mean-square error approximately 0.013. This model partially addresses...
Natural soiling, or the deposition of ambient particulate matter (PM) onto surface solar glass, causes losses in PV production around world. Much work community has focused on soiling dusty desert environments. However, systems urban environments are exposed to different contaminants and thus soil differently. We present an analysis such environment considering impacts meteorological parameters. 1 year results from a station location Colorado. Bare glass samples were outdoors for 11 days...

Natural soiling has reduced the energy output of PV systems since technology was first used, and viable mitigation strategies have remained elusive ever since. With ever-increasing deployments around world, especially in dusty environments, is becoming a billion-dollar problem, worldwide. Furthermore, as plant operators continue to look for ways increase revenue, operating voltages increased between 1000 V 1500 when sun shining. This resulted some unforeseen consequences nominally combined...
