Why Act Now?
The hidden cost of dirt build-up
Dust, pollen, industrial particles and bird droppings = blocked photons = lost kWh.
In Belgium, soiling-related losses typically range between 3% and 10%, and can exceed 15–20% on highly exposed sites such as flat roofs, wooded areas, car parks, farms or near busy roads.
Rain alone isn’t enough to remove certain types of residue — especially pollen or greasy films.
Our goal: restore full light transmission and recover immediately measurable performance on your inverter readings.
What You Gain
+kWh consumed : reduction in grid purchases during peak hours.
Fast ROI : a gain of +5 to +15% on annual production more than covers regular maintenance (depending on context).
Fewer alerts & overheating : limit hotspots and micro-stress related to persistent dirt.
Image & compliance : clean site, HSE procedures respected, traceability provided.
They Trust Us
How We Maximise Performance — Safely
Audit & Access Plan
Assessment of height, tilt, access method (cherry picker or lifeline), perimeter and HSE constraints.
Cleaning with Deionised (DI) Water
Telescopic poles with specialised microfibre or brush heads — no harsh detergents.
Products are only used when necessary and always pre-approved.
Dry Quality Check
Panels are inspected once dry to ensure no streaks or residue. Immediate touch-ups if required.
Full Traceability
Before-and-after report including photos, treated surface areas, any site constraints and recommendations.
Professional Coordination
Work scheduled outside opening hours or at weekends, in full coordination with your HSE and Facilities teams.
Cleaning Frequency — Tailored to Your Site
Once a year
ideal for most commercial and industrial sites
Twice or four times a year
for dusty, high-exposure or pollen-prone environments
On demand
after construction, storms or dry, dusty periods
We provide maintenance contracts with automatic planning and centralised reporting — so you stay efficient with zero admin.
Sectors We Serve

FAQ – Performance
1. What kind of gain can I expect?
Most often between +5% and +15%, depending on exposure and condition.
In cases of heavy soiling, gains of over 20% are possible.
We measure the effect using your inverter readings before and after cleaning.
2. Is rain enough to clean the panels?
No — not for certain types of residue such as pollen, greasy films, or bird droppings.
A professional clean restores full light transmission and surface uniformity.
3. Is there any risk to the panels?
Our method follows strict HSE procedures, using deionised water, suitable tools, and a dry inspection at the end.
We never use high-pressure jets in contact with the modules.
4. Do you operate while the site is open?
Yes — we secure the work area with barriers and safety zones, and always give priority to off-peak or non-public hours.
