Anti-soiling coatings for Sun Simba concentrated photovoltaic (CPV) modules

摘要: Soiling is a major source of power degradation in photovoltaic (PV) modules, with variable impact as function environmental conditions. For concentrated (CPV) modules the greater due to requirements preserving optical path within module. In an effort reduce soiling number self-cleaning coatings have been developed and implemented solar modules. Self-cleaning films are generally based on high (hydrophilic) or low (hydrophobic) surface energy materials that leverage extreme wetting behavior contamination, and/or photocatalytic decompose contaminants ultraviolet (UV) activation. this study we explore third-party coating losses Morgan Solar’s Sun Simba CPV The primary objective identify solutions mechanically robust effective anti-soiling, well compatible our concentration architecture. preliminary testing two products were compared characteristics. material 1 reduces rates 0.8-1.4%/month, whereas 2 failed module soiled at rate 6.6%/month consequence – control 4.1%/month for comparison. We followed-up deployment long-term will compare 4 self-cleaning/easy-to-clean products. selected their characteristics suitable properties.
