Dust Accumulation On Solar Panels

Dust property consist of size components shape and weight.

Dust accumulation on solar panels.

Accumulation of dirt or particles like dust water sand and moss on the surface of solar photovoltaic panel obstruct or distract light energy from reaching the solar cells. Dust deposition on pv surface can be stud ied by dust properties composition size of particles and surrounding environmental conditions. For example in malaysia the dust in acidic and can cause erosion to the surface of the panel. Besides some studies deposited the dust artificially on the surface of tested pv panels without exposing the panels to natural dust accumulation outdoors.

The performances of such devices are significantly affected by dust accumulation. The accumulation of dust on the surface of pv module reduces the glass cover transmittance and hence decreases the amount of solar irradiation reaching the cells. When solar panels lie flat water can pool on them and have nowhere to go. Worse things such as leaves and other debris can land on solar panels and just stay there and seriously affect performance.

Regarding the dust accumulation process the specified period for accumulating the dust over the tested pv panels was different in each study. Various impacts and reasons of dust accumulation on pv modules are explained. The findings show that the accumulation of airborne particles both in the shape of dust and anthropic pollution on solar cells can grind their output down by more than 25 in certain regions. Generally low wind is known to be a cause of dust accumulation on panels whereas high wind is known for cleaning action.

This is a major problem since the light obstruction materials pose as external resistances that reduce solar photovoltaic performance. Dust accumulation on solar module surface is an issue of great concern especially in desert regions where occasional to frequent dust storms do occur. Dust storms descended on western new south wales with clouds so thick they blocked out the sun in canberra hailstorms battered cars houses greenhouses and solar panels. Dust accumulation on the surface of solar pv modules mirrors reflectors and other solar collectors is of great concern due to occasional to frequent dust storm in the gulf region.

Eventually it evaporates and leaves grime behind. But a small percentage around 8 percent was from. There are two interdependent parameters that effect on characterization of soiling accumulation on solar panels the property of dust and the local environment. This summer bushfire smoke has blanketed towns and cities across australia.
