Our process
How we clean it
Check the panels and access
We look at the roof pitch and panel layout to plan a safe cleaning approach from ground level.
Clean with purified water
A soft brush head and purified water lift dust, pollen and bird droppings without scrubbing hard at the glass.
Rinse and leave to dry
Purified water dries without spots, so no film is left across the cells once the pole moves on.
No detergents, ever
We avoid detergents and abrasive tools that could damage the panel coating or affect a manufacturer's warranty.
Tools & equipment we use
- Telescopic water-fed pole
- Purified (deionised) water system
- Soft brush head suited to solar glass
- Ground-based access equipment
Our recommendation
Panels tend to lose a little efficiency as dust and grime build up, so a clean once or twice a year is common, more often near trees or busy roads. It's always worth checking your panel warranty terms before any cleaning company works on them, ours included.
