Dust Accumulation On Solar Panels

Besides some studies deposited the dust artificially on the surface of tested pv panels without exposing the panels to natural dust accumulation outdoors.

Dust accumulation on solar panels.

This summer bushfire smoke has blanketed towns and cities across australia. But a small percentage around 8 percent was from. This is a major problem since the light obstruction materials pose as external resistances that reduce solar photovoltaic performance. Regarding the dust accumulation process the specified period for accumulating the dust over the tested pv panels was different in each study.

For example in malaysia the dust in acidic and can cause erosion to the surface of the panel. Dust property consist of size components shape and weight. Most of the stuff caked on the panels was ordinary dirt and dust. Generally low wind is known to be a cause of dust accumulation on panels whereas high wind is known for cleaning action.

After cleaning the study s solar panels saw a 50 percent jump in efficiency. So how do hailstorms dust storms and smoke affect your solar panel performance. There are two interdependent parameters that effect on characterization of soiling accumulation on solar panels the property of dust and the local environment. 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.

The performances of such devices are significantly affected by dust accumulation. When solar panels lie flat water can pool on them and have nowhere to go. 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. 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.

Worse things such as leaves and other debris can land on solar panels and just stay there and seriously affect performance. Dust deposition on pv surface can be stud ied by dust properties composition size of particles and surrounding environmental conditions. 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. Various impacts and reasons of dust accumulation on pv modules are explained.
