EU-funded initiative set to launch new anti-soiling coating



A project backed by the European Union’s Horizon 2020 program says it has developed a self-cleaning coating for modules which is also anti reflective and weather resistant. The project – SolarSharc – expects to launch the product next year.

According to the European Commission’s Community Research and Development Information Service (CORDIS), a project funded by the EU has successfully developed a glass coating for PV modules which is anti-reflective and anti-soiling.

The project, ‘Solarsharc – A durable self-clean coating for solar panels to improve PV energy generation efficiency’ began in 2017. It is led by London’s South Bank University and has had participation from the French Alternative Energies and Atomic Energy Commission, materials producers Millidyne and Opus Materials, and building integrated PV specialist Onyx Solar.

The coating, according to the project’s website, is an inorganic-organic hybrid which uses silica nano particles in a configuration which combines transparency, water repellency and durability.

Europe’s CORDIS estimates dirt on solar panels causes losses of power generation worth more than €40 billion per year; and could be responsible for more than 100 million tons of carbon dioxide emissions – if fossil fuels are used to cover the lost energy output.

Grant brings coating nearer production

The project requested a €2.78 million grant last year, with the aim of bringing the SolarSharc coating technology from prototype level to operational demonstration and certification, and with a supply chain set up to deliver rapid growth. A new report from CORDIS states the product will be launched next year.

A project description on the CORDIS website states: “Commercialization of SolarSharc will develop new revenues for the consortium of €71 million, with profits of €45 million, cumulative, over five years of sales. These sales will increase output from new solar installations by 9,000 GWh, saving 5 million tons of CO² emission.”

Several modules in production already include an anti-reflective coating to boost output, and Dutch materials company DSM is in the process of launching a coating to be applied retroactively to older modules. Anti-soiling coatings are also gaining ground commercially, as project developers gain further understanding of how they can boost project output and keep operations and maintenance costs to a minimum.
