“…Protective anti-soiling coatings provide a viable solution to the above problems [4][5][6][7][8][9][10]. The application of a non-stick barrier renders cohesion forces among same particles larger than adhesion forces among different particles and self-cleaning of dirty surfaces is facilitated.…”

Power output of concentrated solar power systems (CSP) is strongly dependent on mirror reflectivity, which in turn, is affected by soiling and atmospheric conditions. Anti-soiling coatings can enhance efficiency of CSP plants while reducing operating and maintenance costs. Most of them however, suffer from poor endurance and performance. Transparent smooth coatings based on quaternarized silanes may be a viable approach in order to minimize energy losses attributed to soiling.

“…Optimization of the system's effi ciency [6][7][8] is thus diligently pursued. In addition, the implementation of anti-soiling coatings has been recently intensifi ed [9][10][11][12][13][14][15] representing perhaps the most promising solution in solar power projects, since effectiveness is usually combined with low application costs.…”

“…Most hydrophilic coatings have a photocatalytic functionality being able to decompose organic matter by sun irradiation [15][16][17][18]. However, a large portion of environmental pollution is of an inorganic nature, therefore, predicting the performance of hydrophilic coatings in real outdoor conditions, especially arid climates, may be challenging.…”

Soiling of conventional Photovoltaic (PV) modules and Concentrated Solar Power (CSP) mirrors significantly affects the efficiency of the system. Although there are several soiling mitigation strategies, none of them has been widely adopted, since effectiveness in real field conditions is often disputed. Anti-soiling coatings are perhaps the most promising solution for solar power projects since they combine low cost and effectiveness. These are broadly categorized into hydrophilic and hydrophobic. Hydrophilic coatings perform better in arid climates, whereas hydrophobic coatings have a wider spectrum of functionality. Most of them however suffer from various drawbacks, such as poor durability and transmittance which restrict the extent of benefits. In addition, there are only a few reliable technologies that can be retrofitted to existing installations. Predicting the efficiency of a given anti-soiling coating in a specific plant is difficult, therefore, the objective of this work was to identify those parameters that are critical to their performance in real outdoor conditions. Focus was given to the drawbacks of current hydrophobic coating systems and the requirements that a modern anti-soiling coating should satisfy in order to be implemented as an effective after-market solution to degraded solar systems. A prominent example of cutting-edge, high-performing self-cleaning technology, i.e. the SolarSkin system developed by BFP Advanced Technologies, is additionally presented. The latter can renovate deteriorated solar collectors, increase the energy yield of the system, and protect it from weathering effects over its expected operational lifecycle. Potential increment of the system’s efficacy as well as maintenance savings are also briefly discussed.
