Depending on the environmental conditions, the different surface structures and anti-reflection coatings, which are applied on the glass in order to increase the annual gain of a PV module, may turn non-effective and glass transmittance may decrease below the level of unstructured or uncoated glass. Former investigations revealed enormous decreases in efficiency due to heavy soiling, up to -80% within a period of 6 month. Therefore, anti-soiling coatings, which aim to reduce these losses, are a very interesting and promising topic. The market for anti-soiling coatings was screened. Different commercialy available anti-soiling coatings are investigated regarding their functionality, their initial anti-soiling efficiency as well as in terms of weathering stability. A profitability analysis for a simulated 10 MW PV power plant is implemented in regard to the anti-soiling yield gain. The coated PV glazings show different susceptibilities to the soiling test methods. This indicates a variation in wettability of the coatings, monitored by contact angle tests during the intercourse of the study.enPhotovoltaische ModuleSysteme und ZuverlässigkeitPhotovoltaische Module und KraftwerkePhotovoltaische Module - Systeme und ZuverlässigkeitGebrauchsdauer von Modulen und MaterialienGebrauchsdaueranalyse und UmweltsimulationCharacterizationDegradationanalysisModelingcoatingconference paper
