The presented study deals with the use of nonwoven textile materials for dry cleaning of solar panels. This is a topic of high relevance as it integrates sustainability and efficiency, within the context of renewable energy infrastructure. An experimental study, under laboratory and field conditions, of the cleaning ability of non-woven textile materials for solar system maintenance is conducted. The field studies are performed in a real existing solar park, operating under highly dusty environmental conditions. The laboratory studies were performed in order to investigate the tested textile structure, as well as the cleaning ability of the test samples. The achieved results demonstrate a tendency, that when the surface of solar panels is lightly soiled, microfiber cloths and nonwoven polyester cloths have equal cleaning abilities. This result leads to a prerequisite for lower input of resources for the production of non-woven cleaning materials, suggested for use in lightly dusted conditions.
