Self-Cleaning Solar Panels to Avoid the Effects of Accumulated Dust on Solar Panels Transmittance

In previous experiments, dust accumulation for the solar panels has been investigated for a long period of time which is approximately one year [1]. The experiments have been done in different countries which have climate conditions of the dusty weather. Those countries are Iraq, Egypt and UAE. The solar panels were never cleaned, firstly for one month, secondly for two months and so on. The results were there was a decreasing in the transmittance of the solar panels, which is emphasize the effect of accumulated dust, even though the changing in the tilt angel which is in conjunction with the dust deposition on the panels. A well designed auto cleaning system to clean the solar panels will be added to the panels to keep the transmittance of the solar planes fixed approximately and to reduce the cost- of periodic cleaning
