Operators: Supercharge Your Solar Panels with Nanotech
By Lotus Nano
It's astonishing that even in the few minutes you need to read this article there will be solar panels installed somewhere - without nanocoating. You might say: So What?Superhydrophobic coatings are not the only thing, the Nanotech universe has on offer to the Solar/PV world. There are several other nanocoatings, such as anti-reflective, hydrophilic, temperature control, light-trapping and others which are slowly entering the market (even combinations of several desirable properties) and they all cater for particular purposes and climate conditions. But in most cases, and especially in India a performant superhydrophobic coating can bring remarkable performance gains.
There's a lot nanocoating can do if all is done right even for retrofitted on operational panels. An investment that pays for itself. In this article, we will introduce you to a specific nanocoating that can work wonders on Solar/PV panels, particularly in climates similar to South and Southeast Asia.
We'll be discussing specifically Superhydrophobic nanocoatings in this article. We'll have a look at how they can lead to increased efficiency, reduced maintenance costs, and extended the lifespan. The potential is considerable and the investment to do it pays by itself with the performance gains you'd otherwise not seen.
1. Benefits of Superhydrophobic Coatings
Superhydrophobic coatings offer a number of benefits for solar energy companies, including:
- Increased efficiency: When solar panels are covered in water or dirt, they become less efficient at converting sunlight into energy. Superhydrophobic coatings can repel water and dirt, allowing solar panels to operate at their maximum efficiency.
- Reduced maintenance costs: By repelling water and dirt, superhydrophobic coatings can significantly reduce the amount of cleaning and maintenance required for solar panels. This can lead to cost savings for solar energy companies over time.
- Increased lifespan: Superhydrophobic coatings can also help to extend the lifespan of solar panels by protecting them from water damage and other environmental factors.
- Environmentally friendly: Superhydrophobic coatings are environmentally friendly as they reduce the amount of water and cleaning products needed to maintain solar panels, which can also reduce the carbon footprint of solar energy companies.
2. Super-Hydrophobicity - What's that?
Superhydrophobic coatings are a relatively new and innovative nanotechnology that have gained immense popularity in recent years, becoming increasingly relevant in more and more industries. Thanks to their unique properties, these coatings have a wide range of potential uses in many different areas.
The science behind superhydrophobic coatings is fascinating and complex. As mentioned before, these coatings are made up of nanoscale structures that are designed to trap air between them. However, these structures can take many different shapes and forms, depending on their intended application. For example, some coatings may use a random distribution of nanostructures, while others may use a more organised pattern.
One of the most promising applications for superhydrophobic coatings is in the field of solar panels. By applying these coatings to the surface of solar panels, a thin layer is created that prevents water and dirt from sticking to the surface. This can lead to significant increases in the efficiency of the solar panels, as dirt and debris can significantly reduce their effectiveness.
When examining the components of superhydrophobic coatings, we can see that they are typically made up of two main layers: a substrate and a topcoat. The substrate is the base layer that is applied to the surface, while the topcoat is the layer that contains the nanoscale structures. It is the topcoat that creates the superhydrophobic effect, as it is the layer that repels water and other liquids.
3. Case Studies
Many solar energy operators and producers have already started using superhydrophobic coatings on their solar panels, with positive results. For example, a solar energy company in Arizona, USA, applied a superhydrophobic coating to a test panel and found that it required 75% less cleaning than an uncoated panel over the course of a year. Another solar energy company in Spain used a superhydrophobic coating on their solar panels and saw a 7% increase in energy output.
Check out our case study on how we achieved a 13% increase in energy output, near-zero water consumption, and a 50% reduction in cleaning cycles and time for a solar project in KSA. Read it here. These are of cause extremely positive results and (you guessed it) clearly not the norm. But what we can say with confidence today after numerous trials and pilot projects especially in India that 3 to 6% performance gains are realistic including the cutting of water consumption by minimum 50%. This is considerable.
4. Application Procedure
Applying superhydrophobic nanocoating to solar panels involves a simple but not a trivial process.
First, the panels are cleaned thoroughly to remove any dust, dirt, or debris. Then, the nanocoating is sprayed onto the surface of the panels. There are a number of techniques. The panels are left to dry for a certain period of time, typically a few hours, before they can be tested for their water-repellent properties.
The thickness of the nanocoating layer can vary depending on the type and strength of the coating used. Generally, a thicker coating layer provides better water-repellent properties, but it may also affect the panels’ performance by reducing the amount of sunlight that can pass through the coating.
It’s therefore important to note that the application process of superhydrophobic nanocoating should be done by professionals to ensure the proper application to get the best results.
