Solar Panel Cleaning in Sydney
Solar panel cleaning in Sydney for homes, strata and commercial roofs. Purified water and soft brushes, no pressure or chemicals.
How does solar panel cleaning work?
Solar panels in Sydney collect dust, pollen, salt spray, leaf litter and bird droppings, and rain alone does not clean them properly. That build-up blocks light from reaching the cells and lowers how much power the system makes. Bird droppings are a particular problem because a single shaded area can pull down the output of the whole panel string.
We clean panels with purified water and soft, non-abrasive brushes designed for solar glass. There is no high pressure and no harsh chemicals, so the glass, seals, frames and anti-reflective coating are protected, and the panels dry without spotting. It is the method panel manufacturers generally recommend.
For homes, a clean once a year suits many systems, more often near the coast, main roads or trees. For strata buildings, offices, warehouses, schools and other commercial sites, larger and low-tilt arrays tend to get dirty faster, so we can set up a regular six-monthly schedule and work around site hours and access rules.
Every job starts with a free, fixed quote. Let us know roughly how many panels you have, how many storeys the building is and how the roof is accessed, and we will confirm the details before any work starts. While we are up there, we will let you know if we spot a cracked panel or other visible damage.

FAQ
Solar Panel Cleaning, your questions answered
Will cleaning my solar panels improve their output?
If the panels are dirty, usually yes. Dust, pollen, salt and bird droppings block light from reaching the cells, and bird droppings in particular can shade a panel and drag down the whole string. How much output you get back depends on how dirty the panels were, so the best check is to compare your inverter or app readings before and after.
How do you clean solar panels without damaging them?
We use purified water and soft, non-abrasive brushes made for solar glass. There is no high pressure, no harsh chemicals and no abrasive scrubbing, which is the approach panel manufacturers generally recommend to protect the glass, seals and anti-reflective coating.
Will cleaning void my solar panel warranty?
Not when it is done correctly. Warranties are usually put at risk by high pressure, harsh chemicals or abrasive tools, which is why we use purified water and soft brushes only. Check your manufacturer's care guide if you are unsure, and we are happy to work to it.
How often should solar panels be cleaned in Sydney?
Once a year suits many homes. Panels near the coast, main roads, construction, trees or flight paths, and low-tilt or flat-mounted commercial arrays, often need it every six months because dirt and salt build up faster.
Doesn't rain clean solar panels?
Only partly. Rain rinses off some loose dust, but it often leaves a film behind and does little for bird droppings, lichen or grime along the bottom edge of the frame, where dirt tends to collect. Flat or low-tilt panels hold even more.
Do you clean commercial and strata solar systems?
Yes. We clean residential rooftop systems and larger arrays on strata buildings, offices, warehouses, schools and other commercial properties, and can schedule regular cleans around your site's hours and access requirements.
Is it safe to clean solar panels myself?
We do not recommend it. It means working on a roof, panels can get very hot, and the wrong tools or cleaners can scratch the glass or risk the warranty. Never use a pressure washer on solar panels.
How often should I have this done?
For most Sydney homes, every 12–18 months keeps mould and grime from taking hold, sooner for properties near the coast, under trees, or in damp, shaded spots. On an AW+ plan we track the timing for you so it never gets forgotten.
Do I need to be home while you work?
Not necessarily. As long as we can access the areas being cleaned and an outdoor tap, plenty of our residential jobs are done while you're out, we confirm everything beforehand and send photos when it's finished.
Are you fully insured?
Yes, AW Pressure Washing is fully insured, and we're owner-operated, so the person who quotes your job is the person responsible for the result.
Is the quote really free and fixed?
Yes. Quotes are free and fixed, you'll know the price before we start, with no hourly meter and no surprises on the invoice. A quick text with a couple of photos is usually all we need.
Pressure washing or soft washing: which will you use?
Whichever the surface needs. Hard surfaces like concrete driveways take high pressure; render, roofs, timber and painted surfaces get a low-pressure soft wash. We are trained in both and always match the method to the material.
