The Service
Why Your Panels Need Professional Cleaning
Dust, bird droppings, and airborne grime accumulate on panel glass daily. Because solar panels have no self-cleaning mechanism, this buildup compounds over time — silently cutting your generation. Studies in Sri Lanka’s climate show an average output loss of 12–18% after just a few months without cleaning.
Our technicians use a portable pure-water rig with deionised water — the same method used by commercial solar farms. No detergents, no pressure jets that could stress panel seals, and no tap-water minerals that leave streaks. Just a clear, high-transmission surface that generates at full capacity again.

The Process
What Happens on Every Visit
Site Assessment
Our technician inspects panel condition, soiling level, and access safety before any cleaning begins. No cleaning starts until we are confident it is safe.
Dry Brush Pre-clean
Loose dust and debris are removed with soft anti-static brushes to avoid scratching the glass surface or dislodging any micro-cracks.
Deionised Water Wash
Panels are washed with purified, mineral-free water. No detergents, no chemicals — just pure water that dries streak-free and leaves zero residue.
Output Verification
We compare before-and-after generation readings and send you a short report confirming the improvement. You see exactly what you gained.

Common Questions
Solar Cleaning — Answered
In Sri Lanka's climate, we recommend cleaning every 6 months. Coastal areas and properties near roads or construction sites may benefit from quarterly visits due to higher dust and salt deposition.
No. Our process uses only pure deionised water and soft brushes approved by panel manufacturers. We carry no abrasive chemicals and follow all OEM cleaning guidelines — your warranty remains fully intact.
Not necessarily. As long as our technician can safely access the roof and the inverter display, you do not need to be present. We will send you a before/after report by email on the same day.
Tap water contains minerals that leave white streaks and residue on panel glass when they dry. Deionised water has zero dissolved solids — it dries perfectly clear, keeping panels at maximum transmission.
Every Sunflower solar installation includes two complimentary professional cleaning visits within the first 18 months — scheduled automatically at 6 and 12 months after your system goes live.
