This technology presents a unique anti-soiling coating formulation for photovoltaic (PV) solar panels which has been developed to reduce maintenance cost and improve energy efficiency. Specifically, the coating can significantly reduce the amount of water used in cleaning operations and facilitate easy removal of hard stains such as cement dust, mud, sand, dust, hard water stains, bird fouling. Combining with its anti-reflective (AR) property, the coating can increase the power output by 5-10%. The coating can be applied on-site or in the factory during PV panel production and is ideal for protection of PV installations at locations where soiling is prominent, e.g. coastal areas, desert regions, industrially polluted places, floating solar, etc.
Easy cleaning solutions are required for many applications to reduce the usage of water and manpower. The market is adopting coatings which are low in surface energy and show non-stick behaviour. This is particularly true for applications in remote locations and where deployment of resources is difficult.
