Dust is generated from so many different sources such as desert storms, industrial emissions, construction debris, highway activities etc.

Dust concentration in the atmosphere depends on the local topography, climate conditions, industrial activities and agricultural activities and varies across the world.

Find below atmospheric dust concentration of various locations and their intensity indicating the Middle East & North Africa region as the location with the highest concentration.

Deposition of dust on PV is strongly dependent on wind speed and particle matter. Dust accumulation or soiling is an unavoidable factor that affects solar PV module performance and is considered as one of the major factors after solar radiation and temperature.

When considering surface orientation as a factor, dust accumulation is highest if the PV module surface is horizontally positioned and is moderate when tilted. 

A solar cell of a PV module cannot respond to wider spectrum sunlight because photons that have lower energy than the solar cells cannot be absorbed causing a material bandgap.

Suspended dust in the atmosphere tends to reduce the performance of the PV module; however, this has a lesser effect than the dust that settles on the PV surface.

N.J. Middleton in Desert dust hazards: a global review reported that dust could degrade the performance of PV from about 15% to 30% in moderate dust conditions and if cementation occurs, it can reach up to 100%.
