Solar panels feature specialized anti-reflective coatings and delicate glass seals. Using tap water, abrasive detergents, or high-pressure washers will damage your panels and void manufacturer warranties. We rely strictly on a pure-water low-pressure cleaning process:
100% De-Ionized Pure Water: Our multi-stage filtration system strips out all minerals, hard water deposits, and limescale. Pure water attracts surface grime naturally and dries 100% spot-free without leaving residue.
Non-Abrasive Solar Brushes: We use ultra-soft, purpose-built solar brushes designed to gently lift bird droppings, pollen, tree sap, and lichen without scratching the glass face.
Zero High Pressure: High-pressure lances force water past panel seals and micro-fracture solar cells. We clean exclusively with gentle, low-pressure pure water streams.
Ground & Scaffold Access: High-reach carbon-fiber poles allow us to clean roof-mounted arrays safely from ground level or mobile scaffold towers—eliminating unnecessary foot traffic around your panels.
Irish weather keeps panels wet, but rain alone does not clean solar arrays. Over time, sticky grime and lichen build up, directly cutting into your electricity savings:
No. Think of your car windshield—rain washes away loose dust, but leaves behind sticky film, pollen, and bird droppings. Solar panels sit at a low tilt angle where grime bakes onto the glass under the sun, requiring targeted pure-water washing to remove.
Never. High pressure shatters solar glass, breaks thermal seals, and fractures internal silicon cells. Furthermore, tap water contains minerals like calcium that leave white spots when dry, blocking sunlight.
It is not strictly necessary, as our soft brushes and pure water touch only the exterior glass and aluminum frame. However, if you prefer to shut down the inverter during the clean, our crew can wait while you switch off the system.
We recommend a deep pure-water clean once every 12 to 18 months. Properties located near agricultural land, busy roads, or under heavy bird flight paths benefit from annual maintenance.
