Up to 30% power loss from dirt build-up. Our TÜV- and CE-certified cleaning robots restore your solar system to 100% efficiency – using deionised water and scratch-free technology.
Why do solar
panels get dirty?
Your system's performance drops every day – invisibly, but measurably. Here are the main causes of power loss:
Bird droppings & organic residue
Bird droppings contain acids that attack the glass surface. Pollen, seeds and tree resin form sticky layers that rain cannot wash away.
Dust & environmental pollution
Agricultural dust, road dust, industrial emissions and exhaust residue settle as a fine film on the surface.
Limescale & water residue
Cleaning with tap water leaves mineral deposits behind. Rainwater evaporates and leaves visible limescale stains.
Important: rain alone is not enough!
Many people believe rain cleans the panels. Wrong! Rainwater contains minerals and leaves even more residue behind as it evaporates. Professional cleaning is needed every 3-6 months.
What happens when
maintenance is skipped?
From the first traces of dirt to a voided warranty: here's how a hotspot forms – and why it's dangerous.
Dirt builds up
Bird droppings, moss, algae, and leaves settle layer by layer on the panel surface – rainwater alone won't wash them away.
Heat builds up locally
The soiled area blocks sunlight unevenly, causing that one cell to heat up far more than the rest of the panel.
Hotspot & fire risk
The resulting hotspot can permanently damage the solar cell, cause micro-cracks, and in extreme cases even trigger a fire.
Warranty voided
Most manufacturers explicitly exclude damage from inadequate maintenance from coverage – even within a 20–30 year warranty period.
Regular cleaning prevents exactly this
With professional cleaning and thermographic inspection, we catch hotspots early – before they cause damage or void your warranty.
The Seçkin Enerji
cleaning technology
Deionised ultra-pure water (DI water)
Leaves no stains, is non-conductive (no electric shock risk) and prevents corrosion. The only truly safe cleaning method.
Autonomous robot technology
No need for anyone to walk on the roof. No fall risk, no risk of panel breakage. Patented RTM Pro robot with soft brushes.
Thermographic quality control
Before and after cleaning: thermal imaging to detect hotspots, micro-cracks and defective cells. Documented in your quality report.

How much money are you currently losing due to dirty panels?
On average € 0 per month
Did you know?
At a loss of € 0 per day, the cleaning costs already pay for themselves after 0 months. After that, every euro is pure profit.

Why regular cleaning matters
Dirty panels lose noticeable output – here's what you need to know
Performance loss from dirt
Dust, pollen and bird droppings settle on the panel surface and block incoming sunlight. Depending on location and how dirty the panels are, energy loss can reach up to 15-25%, especially on systems that haven't been cleaned in a long time.
Recommended cleaning intervals
For most systems we recommend professional cleaning once or twice a year. Near farmland, busy roads, or coastal areas with salt deposits, a shorter interval can make sense.
Weather and pollen season
In spring, heavy pollen often forms a sticky film on the panels that rain alone barely removes. Saharan dust and long dry spells without enough rainfall also increase the need for cleaning.
Professional cleaning instead of DIY
Working at height, unsuitable brushes, or high water pressure can scratch or damage panels and, in the worst case, void the manufacturer's warranty. Our trained team works with gentle equipment and proper safety gear.
Let our team clean your system professionally and safely – no obligation, tailored to your panels.
