Solar Panel Cleaning: Removing Lichen
Solar panels are a valuable investment for anyone looking to harness solar energy. However, the efficiency of your solar system can be hindered by various factors, including lichen growth. Lichen, a symbiotic organism consisting of fungi and algae, can accumulate on solar panels over time, reducing their performance and energy output. In this guide, we’ll uncover what lichen is, how it builds up on solar panels, the impact it has, and the best methods to clean, remove, and prevent lichen from your solar panels.
What is lichen?
Lichen is a unique organism that combines fungi and algae in a symbiotic relationship. It can grow on various surfaces, including rooftops and solar panels, due to its ability to survive in harsh environments. Lichen appears as a greenish or greyish crust and is often seen in wet conditions or shaded areas. The photosynthetic nature of the algae within lichen allows it to produce energy, while the fungi provide structure and protection. While lichen may seem harmless, its growth on solar panels over an extended period can lead to significant problems over time, such as reducing your solar panel efficiency.
The growth of lichen on solar panels is typically slow but persistent. Lichen grows in areas where moisture and debris accumulate, especially along the bottom edge or shaded regions of the panels on the roof. Given its resilient nature, lichen can cling firmly to surfaces, making it difficult to remove. If ignored, lichen growth can cover the entire panel, blocking sunlight and reducing efficiency.
How does lichen build up on solar panels?
Lichen buildup on solar panels usually begins with the accumulation of moisture and debris. Wet conditions, bird droppings, and organic materials can create a suitable environment for lichen to start growing. Once lichen attaches itself to the surface of the solar panels, it continues to spread across the surface, especially during overcast or humid weather. The growth of lichen is often exacerbated by prolonged exposure to these conditions.
The growth of algae on solar panels is particularly problematic because it can attach itself to the delicate coating on the surface of the panels. The photosynthetic capabilities of lichen allow it to survive even in low-light conditions, further promoting its spread. Over time, lichen growth on solar panels leads to a decrease in panel efficiency by blocking sunlight, ultimately impacting the overall output of the solar system.
How does lichen affect solar panels?
The presence of lichen build-up on solar panels can have a detrimental effect on their performance. Lichen growth directly affects the amount of sunlight that can reach the photovoltaic cells within the panels. As lichen spreads across the panels, it creates a barrier that blocks sunlight from reaching the cells, reducing their ability to convert solar energy into electricity. This loss of efficiency can be significant, especially if the lichen growth is widespread.
Lichen can also cause long-term damage to solar panels. The fungi within lichen can release acidic compounds that contribute to the corrosion of the panel’s surface. This corrosion, combined with the buildup of organic material, can damage the surface of the solar panels, leading to reduced performance and even voiding the warranty in some cases. Regular maintenance and prompt lichen removal are essential to ensuring that solar panels continue to operate at optimal performance.
Furthermore, lichen buildup can lead to uneven power output across the solar system. The affected panels may not produce as much energy as they should, leading to a decrease in the overall efficiency of the solar array. The reduction in panel efficiency caused by lichen growth can also result in higher energy costs as the solar system struggles to generate sufficient power.
How to clean and remove lichen from solar panels
Cleaning lichen off solar panels requires a careful approach to avoid damaging the surface. Here are some effective methods for safely and effectively removing lichen and preventing its regrowth:
Use a soft-bristle brush and hose
For DIY cleaning, start by using a soft-bristle brush attached to a pole to gently scrub the affected areas. A soft-bristle brush ensures that the surface of the solar panels is not scratched or damaged during the cleaning process. Once the lichen is loosened, use a hose with moderate water pressure to rinse the panels. This method is ideal for light-to-moderate lichen buildup.
Avoid using abrasive materials
It’s important to avoid using abrasive materials, harsh chemicals, or high-pressure washers when cleaning solar panels. These can damage the surface area of the panels, reduce their efficiency, and void the warranty. Stick to gentle cleaning methods that effectively remove lichen without causing harm to the panels.
Consider professional solar panel cleaning services
It is highly recommended that you consult professionals about removing the lichen. For stubborn lichen growth or extensive buildup, professional solar panel cleaning services offer the best solution. These experts use specialised equipment and techniques designed for lichen removal without causing damage. Professional cleaning also ensures that all areas, including hard-to-reach spots, are thoroughly cleaned, restoring the panels’ efficiency.
Regular maintenance and lichen prevention
Preventing lichen from growing on your solar panels is key to maintaining their performance. This is true because preventing their growth is more cost-effective than removing them. One of the ways to prevent them is through regular maintenance.
Regular maintenance, such as cleaning your solar panels annually or biannually, helps keep lichen and other debris from accumulating. Additionally, keeping the surrounding environment free of overhanging branches and moss can help prevent lichen growth.
Using innovative, preventive coatings like Nanotech Coating, designed to inhibit the growth of algae and lichen, is also an effective measure. Nanotech coating offers long-lasting protection against lichen, mould and all sorts of fungi. It is also self-cleaning, meaning that not only are your panels protected, they are also wiped clean automatically. Without any challenges, you can easily apply this coating to your panels and watch them shine. If you need more information about this coating, please feel free to contact us.
Conclusion
Lichen growth on solar panels may seem like a minor issue, but it can lead to significant performance problems if left untreated. Many people think rain will be sufficient to remove lichen, but, sorry to disappoint you, an effective removal strategy or innovative preventive measures need to be put in place.
Knowing how lichen builds up and how it affects solar panels, you can take the necessary steps to clean and maintain your system. Removing lichen ensures that your solar panels continue to operate efficiently and generate maximum energy output.
For solar panel owners dealing with lichen and algae growth, investing in proper maintenance and cleaning solutions is the best way to protect your investment and keep your solar panels functioning at their best, and one of the best ways is to apply Nanotech hydrophobic protective coating.

FAQs
How do I clean solar panels with lichen growth?
To clean solar panels affected by lichen growth, you can use a soft-bristle brush head and a hose. Gently scrub the lichen growth to loosen it, then rinse with water. Avoid using abrasive materials or high-pressure washers to prevent damaging the panels. Professional solar solutions are also available if the lichen growth is extensive.
How often should I clean solar panels to prevent lichen growth?
Regular cleaning of your solar panels is recommended at least once or twice a year to prevent lichen growth. Keeping the panels clean ensures they remain free of debris and organic material where lichen might start to grow. Preventive maintenance is crucial to extending the lifespan of your solar panels.
