Solar panel cleaning in Christchurch
Dust, pollen, bird droppings and lichen block sunlight and reduce what your panels produce. We clean them with purified water and soft brushes, leaving no residue and no scratches.
Overview
Dust, pollen, bird droppings and lichen block sunlight and reduce what your panels produce. We clean them with purified water and soft brushes, leaving no residue and no scratches. Maidly provides solar panel cleaning for homes and businesses across Christchurch, from the central city to the coast and the Port Hills.
Why panels need cleaning
Rain doesn't clean solar panels as well as people expect. It moves dust around and leaves a film when it dries, and it won't shift bird droppings or lichen. Anything that shades the cells reduces the power your system makes.
Canterbury's dry nor'west winds carry a lot of dust, and panels near trees collect pollen and leaf litter. A regular clean keeps your system working as it should.
Why purified water
Tap water contains minerals that leave spots when it dries. Purified water dries clear, so panels are left spotless without detergents that can leave a film or damage coatings.

Why it matters
Clean panels make the most of the system you've invested in. Many owners notice the difference on their monitoring app after a clean.
Combining a solar clean with a roof clean is efficient. We can do both on the same visit so your whole roof is looked after at once.
Solar panel cleaning FAQs
Do you walk on the panels?
No. We clean from the roof around the array or from the ground using extension poles, so the panels are never stood on.
Why not just use a hose?
Tap water leaves mineral spots as it dries, and a hose won't remove droppings or lichen. Purified water and gentle brushing give a clean, spot-free finish.
How often should solar panels be cleaned?
Every 6 to 12 months suits most homes. Panels near trees, roads or the coast may benefit from more frequent cleaning.
