“…Dry cleaning using nylon brushes has been shown to have no significant or lasting effect on the optical properties of the glass surface [18]. Deterioration of solar panel surfaces where dust is removed by dry brushing in outdoor conditions is an important factor that reduces the energy efficiency of solar energy systems [27].…”

“…These remain in research and development and are currently expensive to deploy. Self-cleaning methods that prevent the accumulation of dust on the solar panel surface are seen as the best method both in terms of preventing loss in efficiency and extending the life of the solar panel [27]. FluroSurf and PTFE are fluorine-based hydrophobic anti-dust coatings [29,31] that make the glass surface non-adhesive to dust and easy to clean.…”

“…SAW technologies are widely used for precision surface cleaning and particle channeling applications [27]. SAW interactions can create gaseous micro-air flows by penetrating into sloping panel surfaces, causing the surfaces associated with the acoustic areas to vibrate; this effect contributes to the cleaning of the surfaces and areas normally inaccessible to other cleaning methods [27]. Although this cleaning (sweeping) technique is considered as an advantage in energy consumption when evaluated for panel applications that continuously clean itself, a sound intensity of 90 dB that accompanies SAW is not a desired feature for a continuously operating systems [27].…”

This study explores the use of electrostatic cleaning to remove dust from the surface of photovoltaic solar panels. First of all, existing systems used for dust removal from solar panels were evaluated. Then, the effects of dust on the panel were investigated for Şanlıurfa province in Turkey. In addition, the elemental content of the powder was analyzed. A new device for electrostatic cleaning has been designed and implemented. The cleaning performance of this device has been tested considering the electrode designs. The electric field value was determined by analytical and numerical methods in the conventional model (parallel electrode) model. Electric field distribution was investigated using Ansys Maxwell simulation software. The printed circuit boards of the proposed model and the conventional model were produced. The traditional model with positive and negative waveform is widely used in electrostatic cleaner studies. Dust removal efficiencies and electrical losses for different frequency and voltage values were compared for both cards. It has been shown that the proposed model can perform cleaning with high efficiency despite similar loss variation.

Dust repelling from transparent polyvinyl chloride film surface via sonic excitation is examined and dynamics of repelled (inflight) dust particles are analyzed. An experimental rig is designed and built to assess the vibrational characteristics of the polyvinyl chloride film at different frequencies of sonic excitation. A high speed recording system and tracking program are utilized monitoring and evaluating the dynamics of the inflight particles. The dynamics of inflight particles are also simulated numerically and the predictions are compared with those of the experimental data. In order to examine the influence of dust particle adhesion on the dynamics of the inflight particles, the polyvinyl chloride film surface is hydrophobized through dip coating by functionalized nano-silica particles. Improvement of the optical transmittance of the dust mitigated film is determined via outdoor tests. The findings demonstrate that sonic excitation repels the particles from the film surface and it is more pronounced at 64 Hz excitation frequency while demonstrating that sonic excitation can be used for dust removal from transparent surfaces. The mitigation via sonic excitation improves the optical transmittance of the dusty surface by 77%, which becomes more apparent for hydrophobic surfaces.
