SOAKD Exterior Cleaning is a professional exterior cleaning company servicing Sydney, the Central Coast, and Newcastle. Our solar panel cleaning service uses purified water and soft-bristle brush technology to restore panel efficiency safely - without chemicals, high pressure, or methods that could void your manufacturer warranty.
Solar panels are a significant investment in your property and energy costs. But as panels accumulate dust, pollen, bird droppings, salt spray, and environmental grime, their energy output decreases. The glass surface of a solar panel needs to be clean to allow maximum sunlight to reach the photovoltaic cells beneath. Even a thin layer of soiling can reduce output by 15 to 30 percent - meaning your panels are generating less power and saving you less money than they should.
How Dirt Affects Solar Panel Output
Solar panels work by converting sunlight into electricity through photovoltaic cells. Any obstruction on the glass surface - whether dirt, bird droppings, leaf residue, or salt deposits - reduces the amount of light reaching those cells. The impact is not always uniform: concentrated soiling like bird droppings or leaf stains can create "hot spots" that reduce the output of an entire string of cells, not just the one covered.
In coastal NSW, salt spray is a particularly common issue. Salt crystallises on panel surfaces and attracts additional dust and moisture, creating a compounding layer of soiling that rain alone cannot effectively remove.
Our Cleaning Method
We clean solar panels using purified water delivered through a water-fed pole system with soft-bristle brush heads. The purified water contains zero dissolved minerals, so it rinses clean without leaving spots or residue that could create additional shading on the panel surface.
This is the method recommended by the Clean Energy Council and major panel manufacturers including LG, Jinko, Trina, and Canadian Solar. We do not use high pressure, abrasive tools, chemical cleaners, or detergents on solar panels - all of which risk damaging the anti-reflective coating on the glass and voiding your manufacturer warranty.
Warranty-Safe Approach
Solar panel warranties typically include conditions about cleaning methods. Most manufacturers specifically state that high-pressure cleaning, abrasive materials, and chemical solvents will void the panel warranty. Our purified water and soft-bristle method complies with the maintenance requirements of all major panel manufacturers.
Panel Inspection During Cleaning
While cleaning your panels, we visually inspect each one for visible signs of damage or wear: micro-cracks, discolouration, delamination, loose connections, and bird-nesting under the panel array. Any observations are included in our completion report so you can arrange follow-up with your solar installer or electrician if needed.
