Nanoveu, an Australian nanotechnology firm, has developed a multifunctional anti-soiling coating for photo voltaic glass designed to forestall floor particles and algae progress from forming on PV panels.

Nanoveu has developed a hydrophilic self-cleaning nano-coating for photo voltaic panels that it claims reduces potential-induced degradation whereas delivering decreased cleansing prices for PV energy techniques in dry, humid environments.
ASX-listed Nanovue mentioned it has efficiently expanded its Nanoshield product suite to incorporate the E-series arduous coat, an antimicrobial coating that’s self-maintaining, anti-fouling, anti-static, and hydrophilic.
The clear coating, developed from the corporate’s antiviral merchandise, was initially designed to forestall the expansion of algae and lichen on photo voltaic panels. It states that algae progress is a significant concern for photo voltaic techniques deployed in tropical situations and if not managed, could cause as much as 26% vitality loss in module technology capability. Along with stopping algae progress, the corporate says the hydrophilic and anti-static properties of the E-series coating stop sand, dust and different floor contaminants from sticking to the panels.
Nanoveu Managing Director Alfred Chong mentioned the coat’s self-cleaning properties meant contaminants may very well be washed away by rainwater.
“Versus water-repellent coatings, the hydrophilic impact reduces the angle of the water droplets, which permits penetration below the contaminant,” the corporate mentioned. “Antistatic, bigger particle dimension particles resembling dust and sand move simply to the floor.”
Chong claims that the coating’s distinctive properties make it appropriate as a self-cleaning answer for photo voltaic techniques in each humid and dry climates.
“With this new and distinctive growth, we are going to work to ascertain Nanoveu as a gorgeous answer to enhance the efficiency of photo voltaic property worldwide,” he mentioned.
Soiling of photo voltaic panels stays a significant concern for the trade with the Worldwide Power Company’s Photovoltaic Energy Programs Program (IEA-PVPS) estimating that misplaced income from PV module soiling quantities to over AUD 4.67 billion ($3.2 billion) per yr.
The IEA-PVPS estimates that in 2018, air pollution will trigger no less than a 3% to 4% loss in international annual vitality manufacturing from PV. It’s anticipated to extend by round 4% to five%, and $6 billion to $10 billion this yr.
Nanoveu is at present testing the effectivity of the Nanoshield product within the Philippines, with 55 MW of photo voltaic initiatives recognized as appropriate websites for the know-how. The outcomes of the assessments are anticipated to be printed within the first half of this yr.
Nanoveu says Nanoshield can be utilized in different purposes, resembling ships and boat hulls that always require remedy.
