What does it mean to have solar panels cleaned in Maarssen?
Having your solar panels cleaned in Maarssen means choosing maximum yield and sustainability on your roof. Contamination from bird droppings, particulate matter, pollen, and air pollution reduces the efficiency of solar energy systems throughout the Netherlands. In an area like Maarssen, where seasonal influences and industry converge, cleaning company Groene Hart ensures that solar panels continue to perform. By adhering to protocols such as NEN 3140 and working safely at height, we guarantee that every cleaning meets the strictest requirements and safety standards.
Why periodic cleaning of your solar panels is essential
For a long time, it was assumed that rain sufficiently cleans the panels. Scientific research shows that accumulated contamination, such as limescale, algae, and bird droppings, can reduce light transmission by as much as 30 percent. Especially in Maarssen, where panels are located under trees or near industrial sites, periodic maintenance is advisable. At Groene Hart cleaning company, we use reverse osmosis water and soft brushes to prevent micro-scratches. Modern solar panels from brands like SunPower, LG, and Canadian Solar benefit from this for a longer lifespan and to maintain factory-produced efficiency.
- Optimizing power yield By having your solar panels properly cleaned, their energy output increases immediately. This will save you significantly on your energy bills for years to come.
- Recording factory warranty Dirty panels can lead to warranty issues. Professional maintenance will keep your warranty valid, including for Tier 1 brands.
- Extending the lifespan of installations Regular cleaning prevents corrosion and deposits, which contributes to an optimal technical lifespan of PV installations.
- Sustainable and safe cleaning protocol : No chemicals, completely biodegradable and always with VCA-certified personnel.

The step-by-step plan for having solar panels cleaned in Maarssen
Every roof and every installation requires a specialized approach, based on the type of panel, angle of inclination, system configuration, and level of contamination. Our process is fully focused on efficiency and safety:
- Inspection and safety check Before we start, all panels, roof hooks and wiring are carefully checked according to European technical standards.
- Pre-cleaning with osmosis water : Panels are wetted with pure filtered osmosis water to prevent limescale formation and to loosen dirt.
- Soft brush cleaning without pressure We use brush technology specifically designed for glass-on-glass PV panels. This prevents scratches.

This is how cleaning solar panels contributes to higher efficiency and sustainability
Scientific studies, including those by TNO and the Holland Solar knowledge institute, show that a well-maintained solar panel delivers significantly better efficiency. This is especially true for east-west-oriented systems or panels that regularly fog up or become dusty. Periodic cleaning not only has a direct impact on output and yield but also extends the lifespan of all associated hardware, such as inverters and mounting materials from SolarEdge or SMA.
In real-life cases at local businesses in Maarssen, we saw an immediate increase in the output per square meter of PV panel after a one-time deep cleaning of heavily soiled solar panels. This results in a shorter payback period and a stronger positioning of companies as sustainable.

Frequently asked questions
Why is it important to have your solar panels cleaned in Maarssen?
Solar panels in the Netherlands attract a lot of dirt, dust, and algae, especially in a green region like Maarssen. This reduces efficiency and unnecessarily compromises your energy savings. Moreover, a layer of dirt can damage the panel coating over time, according to experts from the RIVM (National Institute for Public Health and the Environment) and TNO Solar Energy.
At Schoonmaakbedrijf Groene Hart, we use special osmosis cleaning, ensuring your panels are cleaned streak-free without chemical agents. This conscious approach prevents damage to the glass layer and immediately increases your yield – and significantly extends the lifespan.

Is it safe to clean solar panels yourself in Maarssen?
Cleaning solar panels yourself sounds appealing, but it carries risks. Safety concerns are especially prevalent with sloped roofs or high, flat roofs. You can also damage the coating by using the wrong cleaning agents or hard brushes.

We use demineralized water and specialized tools to treat the surface safely and thoroughly. This prevents damage and ensures you get the most out of your system.

We use exclusively osmosis water, which is completely free of minerals, so no stains or limescale residue remains. Using telescopic poles and soft brushes, we can work safely from the ground or scaffolding without damaging the surface of your panels. This scientifically proven technique is recommended worldwide by industry organizations such as SolarPower Europe.
This method ensures your panels maintain optimal light transmission and reduces the risk of micro-scratches and other damage. Our cleaning specialists receive annual training, so you always benefit from the latest insights and techniques.
