Heavy soiling needs more than a basic clean. For baked-on bird droppings, sap, lichen and stubborn build-up, we use a targeted panel-safe treatment to remove contamination carefully and document the result with before-and-after photos.
Heavy droppings and soil deposits are acidic and corrosive. The longer they sit on your panels, the more permanent damage they cause—including etching that can't be reversed.
Heavy droppings can affect panel output until they're removed. Early treatment keeps build-up easier to lift away.
Bird droppings can drag down system performance and lead to premature panel failure.
When build-up sits on a panel for an extended period, the cells underneath can be partially blocked from sunlight and become at risk of hot spots and damage.
Bird droppings, lichen and thick dirt can remain on the panels for long periods. Over time, the build-up can harden and become more difficult to remove.
Heavy soiling blocks sunlight from reaching parts of the panel evenly, which can reduce performance. Treating the build-up early also makes it easier to remove safely.
Most panels are fine with a regular maintenance clean. Once contamination is baked in, you need a different approach.
Standard Clean
The right call for panels with general dust, pollen and light bird droppings. Quick, affordable, recommended every 6 to 12 months in SE QLD.
Heavy-Soil Treatment
The right call for panels with thick bird or bat droppings, lichen, baked-on tree sap or visible streaking. A normal wash leaves most of this behind.
A methodical four-step approach that lifts the contamination, protects the panel and gives you proof of the work.
We inspect the severity and type of contamination to determine the best treatment approach.
Specialised cleaning agents are applied to break down stubborn deposits without damaging panels.
Thorough cleaning with purified water removes the loosened contamination and residue.
Complete quality check with before and after photos documenting the result.
Heavy soiling is contamination that has been left long enough to no longer come off with a standard clean, or that comes from a concentrated source like a bird colony, a fruiting tree or a coastal exposure. If you can see thick deposits, dark patches or streaking on the panels from the ground, you probably need treatment, not a wipe-over.
Heavy bird and bat droppings are acidic. Left untreated for long periods, build-up can affect the panel surface. Treatment removes the visible contamination and we note any visible concerns in your service report.
Cleaning may help support performance where build-up is blocking sunlight, but output can also be affected by shading, weather, panel age and electrical condition. We don't guarantee a specific increase — we focus on doing the cleaning properly and documenting what we observed.
Yes. We use panel-safe methods and biodegradable agents, with no abrasive scrubbing or pressure washing. Every visit is documented with before and after photos, kept on file with your service notes.
Yes. After a heavy-soil treatment we usually recommend a maintenance clean every 6 to 12 months to stop the build-up coming back. We'll suggest a schedule that matches your environment, you're not locked in.
