Dust = Loss of money
Impact of Soiling losses
Soiling losses area major threat to the module life and electricity generation efficiency. The accumulation of dust on the surface of the photovoltaic modules decreases the incoming irradiance to the cell and produces power losses. In these cases, the most widely used solution is to clean the modules with water. In large-scale photovoltaic plants this task is often expensive as one must draw water lines, especially in those areas with water shortage. Water is one of most scares resources in arid regions. Soiling losses could be around .5% daily which amounts to 15% monthly loss which has potential to break the assumed energy production numbers of the plant.
