Solar energy is gaining ground in Switzerland, where the cleanliness of solar panels plays a crucial role in their performance. Regular cleaning is essential to maintain the efficiency of the panels. Two methods stand out: manual cleaning, which depends on human effort, and robotic cleaning, facilitated by devices such as the SolarCleano F1.
Manual cleaning uses specific tools and requires direct intervention, while robotic cleaning, with machines such as the SolarCleano F1 Or iSolar of KÄRCHER offers an automatic solution. Each method has its advantages and limitations. This article examines both approaches to help you choose the best option for your installations.
Why is solar panel cleaning essential?
Cleaning your solar panels isn't just about aesthetics; it's crucial to their performance. When panels get dirty, their ability to produce energy decreases.
Effects of dirt on performance
Dirt, dust, leaves, or even bird droppings can obscure the surface of your solar panels, reducing their ability to capture sunlight. Even a thin layer of dust can cause a noticeable drop in efficiency.
In fact, fouling can reduce the solar panel efficiency up to 25%. A thin layer of dirt can also reduce this 10% yield.
These efficiency losses mean that uncleaned solar panels produce less electricity, which directly impacts your energy bill and the profitability of your solar investment.
Consequences of insufficient maintenance
Poor maintenance of solar panels can have serious long-term consequences. The build-up of dirt and debris not only reduces energy efficiency in the short term; it can also lead to permanent damage to solar panels, affecting their durability and long-term operation.
Many solar panel manufacturers make warranty coverage conditional on regular maintenance. Poor maintenance can void the warranty, leaving owners unprotected in the event of failure or reduced performance due to premature wear.
In conclusion, regular maintenance of solar panels is essential to prevent damage, extend the life of the installation and ensure optimal operation. Ignoring necessary maintenance can lead to higher costs in the long term, both in terms of repair and replacement as well as energy production losses.
Manual cleaning of solar panels
Process and tools
Manual cleaning of solar panels is broken down into structured steps for maximum efficiency:
- Initial inspection : Identification of dirty or damaged areas on the panels.
- Preparing the tools : Assembly of necessary equipment, such as soft brushes, squeegees, and microfiber cloths.
- Implementation of security measures : Establishment of protocols to ensure the safety of technicians, particularly for high panels.
- Humidification : Application of demineralized water on the panels to facilitate the removal of impurities.
- Cleaning : Gentle rubbing of the panels with suitable tools to remove dirt without causing damage.
- Rinsing : Remove dirt and cleaner residue with clean water.
- Drying : Allow panels to dry naturally or wipe dry to avoid water marks.
- Inspection and final verification : Control of the cleanliness of the panels and verification of their operational performance.
This methodical process helps maintain the efficiency of solar panels and contributes to their longevity.
Tools used for manual cleaning include soft brushes, squeegees, and microfiber cloths, often used with demineralized or filtered water to prevent limescale deposits. Specific, non-abrasive and environmentally friendly cleaning solutions are also used to remove dirt without damaging the panel surfaces.
Innovations in manual cleaning tools include telescopic poles that allow panels to be reached at height without the need for scaffolding, reducing the risk of falls and injury.
Advantages and Disadvantages of Manual Cleaning on Solar Panels
Benefits
- Precision : Manual cleaning allows you to specifically target dirty or clogged areas, ensuring a complete clean.
- Risk minimization : When done correctly, manual cleaning is less likely to cause damage to panels, compared to some automatic methods which can be too abrasive.
- Flexibility : This method adapts to different types and configurations of solar panels, offering a customized solution according to the specific needs of the installation.
Disadvantages
- Labor requirement : Manual cleaning is often more time-consuming and labor-intensive, requiring significant labor, especially for large installations.
- Risk to personnel : Cleaning panels installed at height can pose a fall hazard for workers.
- Frequency of cleaning : As the process is more time and labor intensive, manual cleaning may not be performed as frequently as necessary, which can lead to dirt build-up and affect panel performance.
In summary, manual cleaning of solar panels offers precise control and is tailored to the specifics of each installation, but it is more labor intensive and presents some risks to personnel. The choice between manual cleaning and other methods will depend on the specific conditions of each site, available resources and safety considerations.
