Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and. . Diamon-Fusion® protective coating for solar panels provides an ultra-thin, invisible barrier that helps keep your solar panels cleaner longer. It is an ideal solution for enhancing photovoltaic performance and increasing energy output on solar panels by allowing more sunlight to pass through the. . The paper systematically reviewed the theory, materials, preparation, and applications of the super-hydrophobic and super-hydrophilic coatings on the photovoltaic modules. This coating can protect solar panels from various weather conditions, dust, UV radiation and decreases the maintenance cost by providing self-cleaning. . CERACOAT ceramic glass SC coating is a water-based system that protects PV panels from dirt and improves the light output. Recent studies show: Between 9% and 16% of PV modules have backsheet problems.
