Anti-soiling coatings for PV applications
DSM has been developing anti-soiling coatings to mitigate the soiling issues by preventing dust/sand from adhering to the module surface, so thatthe soil can be easily removed by either external forces (e.g. wind, rain, gravity) or manual/automatic cleaning processes. The benefit of such coating can be the reduction of the module output loss due to soiling, and/or the reduction of the cleaning costs by lowering cleaning frequency or easier cleaning. This presentation will elaborate on some key aspects of the anti-soiling coating development at DSM, which covers lab soiling test methods, coating performances tested in the lab and outdoor conditions, as well as the influence of cleaning equipment.
