A nano coating with hydrophobic and self-cleaning properties for photovoltaic (PV) and solar thermal panels. The coating’s self-cleaning glass effect stops dust and bird faeces from sticking to PV panels, keeping them clean, maintaining their efficiency, ensuring the maximum amount of electricity is produced. The hydrophobic properties repel water more quickly than uncoated “self-cleaning glass” as found on typical PV panels. This makes cells treated with the Solar Panel Coating more efficient during inclement weather.
