- Safe work at height
More about our solar panel cleaning
An investment in photovoltaic panels pays off over the long term, as long as the cells work at full capacity. In the city and around Brussels, dirt builds up quickly: bird droppings, spring pollen, industrial dust and limescale can cut energy output by 15 to 30% within a few months. What you can't see shows up directly on your electricity bill.
Solar panel cleaning isn't something to improvise. Tap water contains limescale which, as it dries, leaves microscopic deposits on the cells: exactly what you want to avoid. The professional method relies on demineralised water, which evaporates without residue, combined with soft brushes designed specifically for photovoltaic surfaces. No aggressive pressure, no chemicals that could damage the seals.
We work safely on pitched roofs across Brussels and Brabant, with all the necessary protective equipment. After every visit, you receive a report with before and after photos so you can see the recovered output for yourself.

BookHow does our solar panel cleaning work?
Visual check on the roof
We inspect the condition of the panels, fixings and cables before starting. We assess how dirty they are (droppings, pollen, limescale).
Demineralised pre-rinse
A rinse to soften dried-on deposits, especially hardened droppings, without any risk of scratching the photovoltaic cells.
Gentle brushing of the cells
Soft solar panel brushes are worked over the whole surface. Pressure is kept low to protect the cells and the seals.
Final rinse and report
A final rinse with demineralised water that evaporates without leaving limescale. You receive a report with before and after photos.
Questions?
We recommend cleaning once or twice a year, ideally in spring after the pollen season and in autumn after the leaves fall. In urban or farming areas, more frequent cleaning may be worthwhile.
No, it's actually the safest method. Demineralised water leaves no limescale and is used with soft brushes designed for solar panels, with no risk to the cells.
Yes, our teams are trained and equipped for work at height on pitched roofs, with the required personal protective equipment. Safety is our priority.
