Why cleaning solar panels in Leiden is essential
You naturally want your solar panels to perform optimally and maintain a high energy yield. In Leiden, weather influences such as Saharan dust, pollen, bird droppings, and air pollution are particularly detrimental to the efficiency of solar panels. Research by TNO shows that contamination can reduce the performance of solar panels by as much as 20 percent. By having solar panels professionally cleaned, you prevent losses and we ensure that your system generates maximum energy again.
Solar panels operate on the photovoltaic principle, converting sunlight into electricity via semiconductor materials like silicon. Even the slightest layer of dirt can cause variations in light absorption. At Groene Hart Cleaning Company, we use specialized techniques to safely clean solar panels, preventing damage or micro-scratches.
How does solar panel cleaning work in Leiden?
Our team uses reverse osmosis water and extendable brush technology. Reverse osmosis water is ultra-purified water without minerals, leaving no stains or limescale; a technique recognized by Delft University of Technology and used in both businesses and homes. We clean without cleaning agents, protecting both the solar panel and the environment. During the process, we pay attention to:
- Safety: Our employees are VCA certified and always work with fall protection and professional access systems.
- Due diligence: We use soft brushes to protect the glass surface of the panels from scratches and dull spots.
- Durability: osmosis water and biodegradable materials ensure environmentally friendly cleaning.
- Check: After cleaning, we immediately inspect any damage or defects, so you are always aware of the condition of your installation.

Different methods and frequency for cleaning solar panels
Depending on location, slope, contamination, and weather conditions, we always recommend the appropriate cleaning frequency. Panels on a flat roof collect more dirt than on a sloped roof due to the absence of rainwater. We tailor the cleaning method to the type of panel: glass-glass panels, thin-film, polycrystalline, or monocrystalline. Key methods we use:
- Manual brush cleaning: suitable for smaller arrays and hard-to-reach places.
- Osmosis water with telescopic poles: Can be used up to a height of 18 metres and produces 100% streak-free results.
- Mechanical panel cleaning: for larger solar parks or commercial roofs, ensuring all panels are cleaned quickly and effectively.
The cleaning cycle is determined by manufacturer recommendations, inverter monitoring data, and local environmental factors such as bats or trees above the roof.

Frequently asked questions
Why is having solar panels cleaned in Leiden so important?
Dirt, dust, Saharan sand, and bird droppings can accumulate on your solar panels, reducing their power generation by up to 20 percent, according to research by TNO and solar panel expert Erik Blondeel. This simply means you'll get less return on your sustainable investment. By having your panels cleaned regularly by a specialized cleaning company like Schoonmaakbedrijf Groene Hart in Leiden, you'll prevent unnecessary loss and save on additional costs.
We use reverse osmosis water and soft brushes, using the cleaning technique recommended by solar panel manufacturers. This ensures your system remains safe, the manufacturer's warranty remains intact, and you make a sustainable contribution to the environment.
When is the best time to have my solar panels cleaned in Leiden?
Spring and early summer are the best times to have your solar panels professionally cleaned. During these months, you'll notice the most buildup of dirt from pollen, dust, or exhaust fumes in urban areas like Leiden. By keeping them clean going into the sunniest months, you'll maximize your solar energy and prevent loss of performance.
Solar panels in coastal towns like Leiden are particularly susceptible to salt deposits and bird droppings; therefore, experts from Groene Hart Cleaning Company advise checking them regularly and taking immediate action if any visible contamination is found. This way, you'll maintain both your efficiency and lifespan.
How much does it cost to have solar panels cleaned in Leiden?
The cost of cleaning your solar panels in Leiden depends on the number of panels, the type of roof, and accessibility. On average, specialist cleaning costs between €4 and €8 per panel, including certified personnel and professional equipment that meets NEN 3140 electrical safety standards.

Can I clean my solar panels myself or is a professional cleaning company necessary?
It seems simple, but cleaning solar panels requires knowledge of materials, proper cleaning techniques, and, above all, avoiding dangerous situations at height. Incorrect cleaning can cause micro-scratches, which impact efficiency, and you may also void your manufacturer's warranty if you use the wrong cleaning products.
Professional companies like Schoonmaakbedrijf Groene Hart use reverse osmosis water, safe ladder systems, and certified technicians in accordance with the guidelines of manufacturers like SunPower and LG. This ensures that everything is done safely, quickly, and using the latest techniques.
How do you know if your solar panels need cleaning?
Signs such as visible spots, streaks, a dull finish, or a sudden drop in generated energy on your monitoring app often indicate pollution. In cities like Leiden, with heavy traffic and pigeons, we see that panels get dirty more quickly, especially along edges and ventilation openings.
Do you notice that your yield no longer matches previous years, or do you deviate significantly from comparable households? Then it is time to call in Schoonmaakbedrijf Groene Hart for a thorough inspection and professional cleaning. Would you like to know what else we can do for you in the region?
