Your panels, maximum output!
Without a single footstep on your roof.
We clean your solar panels from the air with 100% osmosis water and a certified drone system. Faster, safer and more efficient than traditional methods — for homes, businesses and solar parks across Belgium.

Dirty panels produce up to 30% less.
Solar panels are not self-cleaning surfaces. Dust, pollen, bird droppings and industrial dirt form a layer that blocks light absorption. Rain washes away loose dust at best — the stubborn film remains, hardens and eventually damages the coating.
Indicative values based on studies and measured production differences in the Belgian climate.
From dull and worn to gleaming and productive.
Every cleaning project starts and ends with aerial imagery.
So you see exactly what was done and what it yields.

Cleaning done right: precise, eco-friendly and contact-free.
No ladders, no brushes on your glass, no aggressive agents.
Only demineralised water, precisely dosed from the air.

Drone vs. traditional cleaning
Why do hundreds of owners in Belgium choose aerial cleaning? An objective comparison speaks for itself.
When is the best time to plan a cleaning?
Soiling follows the seasons. Our recommendation per period — with the reason behind it.
Every cleaning is a complete service.
You're not just choosing a cleaning — you get a documented intervention that proves in black and white that your installation is professionally maintained.
- Before and after aerial photos of your installation
- Cleaning with 100% demineralised water
- Risk analysis and flight plan according to EASA regulations
- Fully insured execution
- Short written report of the works
- Advice on maintenance frequency
From 5 panels to 5 hectares — the same precision.
Our approach scales with your installation. Without compromising on quality or safety.

Agricultural business, East Flanders — 480 panels.
Two years without cleaning, panels covered with dust, pollen and manure residue. Traditional cleaning was difficult due to the roof pitch and the aluminium profile. Our drone carried out the full cleaning in a single working day, without stepping on the roof.
What you often want to know before a cleaning.
How often should my solar panels be cleaned?
For most installations in Belgium, one thorough cleaning per year is sufficient. Located near agriculture, industry, motorways or trees? Then we recommend two cleanings per year.
What is the difference with regular tap water?
Tap water contains limescale and minerals that leave stains and effectively undo the cleaning. We work exclusively with osmosis water that dries completely streak-free.
Can the drone cause damage?
No. Our system works without mechanical contact with the panel. Pressure and flow rate are tailored to solar panel glass and anti-reflective coating.
Do I need to be present during the cleaning?
Not necessarily. After a short briefing, site access and any required power supply, we can work independently.
Does this also work in rain or wind?
Light cloud cover is even favourable. In rain, storms or wind gusts above 10 m/s we postpone — safety comes first.
Is the cleaning insured?
Yes. DROPS Belgium is fully insured for material damage, injury and liability during every flight.
