Nanoveu, an Australian nanotechnology firm, has developed a multifunctional anti-soiling coating for photo voltaic glass designed to stop 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 diminished cleansing prices for PV energy programs in dry, humid environments.
ASX-listed Nanovue mentioned it has efficiently expanded its Nanoshield product suite to incorporate the E-series onerous 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 stop the expansion of algae and lichen on photo voltaic panels. It states that algae progress is a significant challenge for photo voltaic programs deployed in tropical circumstances and if not managed, may 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, filth 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 beneath the contaminant,” the corporate mentioned. “Antistatic, bigger particle dimension particles corresponding to filth and sand circulate simply to the floor.”
Chong claims that the coating’s distinctive properties make it appropriate as a self-cleaning answer for photo voltaic programs in each humid and dry climates.
“With this new and distinctive improvement, we’ll work in the direction of establishing Nanoveu as a beautiful answer to enhance the efficiency of photo voltaic belongings worldwide,” he mentioned.
Soiling of photo voltaic panels stays a significant challenge for the trade with the Worldwide Vitality Company’s Photovoltaic Energy Methods Program (IEA-PVPS) estimating that misplaced income from PV module soiling quantities to over AUD 4.67 billion ($3.2 billion) per 12 months.
The IEA-PVPS estimates that in 2018, air pollution will trigger at the very least a 3% to 4% loss in world annual vitality manufacturing from PV. It’s anticipated to extend by round 4% to five%, and $6 billion to $10 billion this 12 months.
Nanoveu is at the moment testing the effectivity of the Nanoshield product within the Philippines, with 55 MW of photo voltaic tasks recognized as appropriate websites for the expertise. The outcomes of the assessments are anticipated to be printed within the first half of this 12 months.
Nanoveu says Nanoshield can be utilized in different functions, corresponding to ships and boat hulls that always require remedy.
