900kmx900km area in the Arabian desert receives solar power that, if converted to electricity, would be enough for the entire world. However dust undermines this resource as dust deposition to solar panels degrades their efficiency. Bottom left figure shows annual dust deposition flux. Top right is the solar panel that was not cleaned for a month. Bottom right – our simulation of dust deposition to a solar panel using particle dust model. These model simulations are design to develop an efficient dust cleaning strategy.
