Solar panel cleaning that measurably increases yield — with manufacturer-approved technology.
Cleaning of solar farms and rooftop systems by robot, with chemical-free water — the panel surface stays free of scratches and micro-cracks. We don't clean unnecessarily: only when the yield increase pays for the cost.
It's not just "a dusty panel" — we know exactly what we are dealing with
Bird dropping removal
Not just an aesthetic problem: the shadow spot forming on the panels can cause hot spots and significantly reduces yield locally.
Dust and industrial deposits
A particularly common, persistently recurring problem at solar farms next to farmland, industrial zones or busy roads.
Pollen and flower dust
A seasonal, thin but evenly spread layer on the surface that measurably reduces light transmission.
Solar farm operators, asset managers and owners of rooftop systems
From industrial solar farms to rooftop systems on commercial buildings, wherever soiling measurably reduces output.
+5–25% efficiency improvement
Depending on the degree of soiling — but cleaning can pay off even at a 1.5–2% yield increase, which we calculate precisely during the assessment.
Free of scratches and micro-cracks
The robot technology has been tested and approved by solar panel manufacturers — the process does not adversely affect the panels' manufacturer warranty.
Chemical-free, ionised water
Leaves no spots, does not damage the panel surface or the anti-reflective coating, and is environmentally friendly.
We only clean if it's worth it
Before every project we prepare a concrete ROI forecast — if the expected yield increase does not cover the cost, we tell you honestly.
What yield increase can you expect?
In Hungary, solar panels typically need cleaning once a year, but with heavy dust, pollen or bird droppings earlier cleaning may be justified. During the assessment we measure the current level of soiling and use it to give a concrete, numerical yield forecast.
Many plants see a 10–25% increase, but an improvement above 5% is achievable in almost every case — and even a 1.5–2% increase can pay back the cost of cleaning.
Soiling is not just an aesthetic issue
Three different technologies — the right solution for every solar plant
We do not rely on a single machine: depending on site conditions (terrain, row spacing, accessibility), we select or combine the best-fitting technology.
SkyTechBrush — towed brush arm
A quick-to-deploy system with joystick and fine hydraulic control, mounted on a tractor or small machine. Excellent for large solar farms on flat terrain.
Solar cleaning robot
A modular, self-propelled robot system that moves directly along the panel row for gentle and effective cleaning — its modular design makes it easy to expand or reduce.
Drone solar cleaning
Effective where a vehicle or robot cannot travel — hard-to-reach sites, uneven terrain or rooftop installations.
Data-driven decisions: we measure and document production data, track soiling trends and weather effects, and measure both before and after washing — so the timing of the wash can also be optimised, which saves cost and maximises yield.
Brushes and water system certified for the panel surface
The robot system moves directly along the panel row, working with brushes and squeegees designed specifically for solar panel surfaces. Mechanical damage to the panel surface is ruled out — the system was tested and approved by the manufacturer, so cleaning does not adversely affect the solar panels' warranty.
Five steps from assessment to verified yield increase
Free on-site assessment
We inspect the solar farm or rooftop system and assess the degree of soiling and the accessibility.
ROI forecast
We give a concrete, numerical payback forecast. We do not recommend cleaning if it does not pay off.
Robot deployment
Commissioning the manufacturer-approved robot fleet on site — the system works so as not to cause scratches or micro-cracks on the panel surface.
Ionised-water cleaning
A chemical-free, gentle but effective cleaning phase that leaves no spots on the panel surface.
Post-clean measurement and ROI report
Before-and-after yield measurement and report, so you can see exactly how much production has increased.
Manufacturer-approved technology, with full insurance
What our clients ask most often before the assessment
No. The robot technology cleans without causing scratches or micro-cracks, works with ionised, chemical-free water that leaves no spots, and does not adversely affect the panels' manufacturer warranty.
In Hungary, once a year is typically ideal, but with heavy dust, pollen or significant bird droppings earlier cleaning may be justified. Based on a free assessment, we clean only if the expected yield increase exceeds the cost.
It depends on the environment and the degree of soiling. Many plants see a 10–25% increase, but an improvement above 5% is achievable in almost every case, and even a 1.5–2% increase can make cleaning worthwhile.
No, we are completely chemical-free. The robots use ionised, demineralised water that dries clean, without spots or streaks, without harming the panels or the environment.
