The sunniest places are often even more dusty. Just think of some parts of India, the Middle East, the Australian outback or, without leaving our country, regions such as Sicily, Puglia and Sardinia.
But it is in these areas that the panels provide the best yields, both for quantity that for intensity of radiation. The “inconvenience” of dust generally decreases the performance of the photovoltaic system up to 40%.
The development of this topic is attended both by the Boston University researchers, supported by Nasa studies, that by the University of Cardiff ones.
The Boston University project takes advantage of research done by Nasa during the missions of Rover on Mars, applying them to solar panels. The module is assembled together with a special coating that can figure out when it accumulates dust on the plant surface. At that point, through a low intensity electrical charge lasting about 2 minutes, the panel is "shaken" by about 90% of the dust.
in this manner solar panels do not accumulate dust and clean themselves autonomously, without human intervention. All this would make possible to install photovoltaic systems even in very dusty areas, often lacking in water for cleaning, increasing the yield of production and greatly reducing the costs associated with cleaning and maintenance.
The Cardiff University, in collaboration with a team of Chinese researchers, founded the system to limit energy production problems resulting from the accumulation of dust, debris and other particles carried by the wind or by birds. Thanks to a relief pattern obtained with special nanoparticles, the surface of the panels become nonstick, limiting the accumulation of impurities.
This treatment makes the panels waterproof, feature that allows to slip away any liquids coming into contact with the surface. The researchers compared their prototype of solar module to a Lotus leaf, which is naturally hydrophobic and non-stick.
In addition to the cleaning aspects, the presence of these microscopic "roughness" makes the surface less reflective, increasing the amount of sunlight that is absorbed and, consequently, the efficiency of the panel.
Once again it is a technology that will improve the performance and efficiency of the panels and at the same time will reduce the costs of maintenance and cleaning of photovoltaic modules.
WHAT IS NANOTECHNOLOGY?
The application of nanotechnology in the cleaning and maintenance of photovoltaic panels can be used to treat surfaces which decompose rapidly stains of any kind.
This special treatment, works by absorbing light and transforming it as a catalyst that protects surfaces and, when the light acts on nanoparticles, surfaces become super hydrophilic and the consequence is that the pollutants are "washed away".
Thanks to this particular combination, increases the transmittance of the panel that acts as an air purifier, because it decomposes organic substances such as volatile organic components (VOC), burnt gases and nitrogen oxides.
As a result the nanotechnology permanently guarantees a cleaner and healthier environment simply by absorbing light.
- Nanoparticles are aggregated irreversibly;
- They protect the solar panel surfaces forever;
- They Continue to disrupt the substances that are deposited on the surface;
- The treatment creates a super hydrophilic, antifogging surface;
- The panels will have greater transmittance, increasing the energy conversion.
Work Innovation Group works in the field of nanotechnology photocatalytic and nanotechnology. The collaboration with the most respected researchers in the field allows us to continually update our certified products, as to introduce them promptly in the market.
Commercially, we are active primarily in the application of the raw material, then to support our customers both during the selection, that in the preparation and application of the product.
Our area of expertise is primarily concerned with the protection of surfaces (photovoltaic panels and glass) from contamination and from the aggression of organic and inorganic substances, facilitating their original conservation over time and their permanent cleaning.
We get surface protection through the use of two categories of products depending on the result we want to achieve: the nanoproducts (passive) and photocatalytic products (active).
Nanoproduct are substances consisting of molecules that have been resized to nanometer level (10-9 meters) in order to change attitudes and characteristics of matter.
They give to the treated surfaces fluid repellency properties and preventing the attachment of contaminants (usually dirt) moreover they increase the luster, the hardness and slow natural deterioration.
The photocatalytic product is explained by the system of photocatalysis, a natural phenomenon whereby a metal compound – called photocatalyst – in the presence of air and UV rays, changes the speed of a chemical reaction that can oxidize organic and inorganic substances, most of which interact in the reaction, decomposing them.
The photocatalyst we use is titanium dioxide, Anatase TiO2 (the rarest and most active form). An important property is to be a highly reactive substance when struck by UV. More precisely, under the action of the light, outer orbit electrons in the TiO2 are released allowing oxygen to react with the substances with which they come into contact, transforming them into harmless molecules such as water and carbon dioxide and also makes the surface almost repellent to liquids.
This has meant that titanium dioxide has been studied to achieve self-cleaning and antibacterial substances. The development of technology has made possible the creation of TiO2 nano-sized crystalline powders, essential to place the chemical reaction. The smaller will be the particle size, the greater will be the contact or displayable under UV light surface, which will allow the release of a higher amount of oxygen radicals.
Our strength is the quality of the products that we use, which are extracted from the highest scientific innovation of the moment. And it is because of two main factors:
THE REALISATION OF NANO-SIZED TITANIUM POWDERS NEVER REACHED SO FAR!
THE USE OF AN ADHESIVE POWDER-SURFACE (PATENTED) THAT ELIMINATED THE PROBLEMS ASSOCIATED WITH DURATION
Each surface has its own characteristics, therefore needs a product and a specific treatment.
In the list below are the actions caused by photocatalysis:
- degradation of organic compounds
- antimicrobial disinfectant action – creates an atmosphere almost free of V.O.C. (volatile organic components): 99.8%
- self-cleaning and anti-fog action
- neutralizing odors
- purifying air and water action
- heat insulation
- high degree of preservation of the original structure
- cleaning without the use of chemicals products (OSMOTIC WATER ONLY)
- totally environmentally friendly
THE MAIN MARKETS IN WHICH WE OPERATE
- Photovoltaic (PV systems on industrial roofing, on land, farms, ranches, solar greenhouses in glass, photovoltaic parks)
- URBAN PLANNING and construction (vertical glass curtain walls with rope climbing technique)
- AGRICULTURAL INDUSTRIAL
We can also carry out all applications even at night, all of our professionals are certified for applying these nanotechnological products.
Before every application and on any kind of surface on which will be applied the nanotechnological products, should be carried out a thorough and specialized cleaning which, a company as Work Innovation Group can make through its experience, its technical and specialized operators and its professional equipment, using osmotic water only and a specific washing with isopropyl alcohol, which is ideal for not leaving any residue or any water substances (especially limestone) on the panel.
Then on the cleaned surface can be made the photocatalytic treatment of photovoltaic panels, which generates greater brilliance and self cleaning water repellent properties, resistance to wear and to break and, most importantly, increase the energy conversion of panel of 5/8%
PHOTOVOLTAIC ARCH TREATED WITH NANOTECHNOLOGY PRODUCTS
This is a picture of a plant where has been used NANOTECHNOLOGY
and after three years the cleaning has not yet been made.
- An increasing of ENERGY CONVERSION YIELD EQUAL to 5/8%
- 25% SAVINGS on MAINTENANCE COSTS
- OSMOTIC WATER SUPPLY
- TRANSPORT COSTS
- ABOUT 30% more profit
to avoid a manual and Highly Expensive cleaning, BESIDES the difficult availability and of Water Transportation ESPECIALLY In PHOTOVOLTAIC parks, THIS TECHNOLOGY COULD be essential To Projects Like "NANOTECH Middle East"
OTHER IMPORTANT ASPECTS
- Reduced adhesion of dust;
- Prevention of limescale;
- Prevents the formation of ice and makes the snow come apart and not remain on the panel;
- Self-cleaning Power (the rain removes most of the dirt deposited which is not fixed on the surface and is deteriorated);
- Reduction of costs of maintenance – the cleaning the panels will no longer be made with short-term rates since a few dusty residue are removed by the rains (when are scarce, can still be cleaned through OSMOTIC WATER, without expensive and harmful detergents, and without the mechanical action of brushes);
- Destruction of organic deposits such as bird droppings or vegetal resins;
- Less reflectance and hence most light that is converted into electricity;
- Reduction of mismatching effect due to the uniformity of the dirt on the panels.
