Design of Smart Surface Cleaner for PV Panels and Investigation of the Performance of Cleaning Materials
Abstract
In this study, a mechanism that automatically detects the contamination on the glass surfaces used in solar cells and collectors and cleans the surfaces has been designed. The performance tests of this automation system were carried out with different pollutants (lime and ash) and the radiation transmittance of the contaminated surfaces was evaluated. It was observed that the radiation transmittance of the glass surface contaminated with lime decreased the most, while the light transmittance of the surface contaminated with ash decreased the least. In addition, the glass surface, which is most polluted with lime, whose radiation transmittance has decreased the most, was cleaned with a felt and microfiber cloth, apart from the well-known rubber wiper and nylon brush. Felt and microfiber fabric used as cleaning material is a new application. As a result; It has been experimentally seen that felt is the best cleaning material.
