Solar Panel Cleaning in Cairns & FNQ
Restore your panels to peak performance with a professional hand wash — safely and thoroughly.
Why Clean Your Solar Panels?
Dust, pollen, bird droppings and FNQ grime build up on your panels over time, reducing the amount of sunlight that reaches the cells. Customers regularly report noticeable improvements in energy generation after a professional clean.
We hand wash every panel carefully — no harsh chemicals, no high-pressure water near seals or wiring. Just a thorough, safe clean that gets your system performing the way it should.
What You Get
- Full hand wash of all panels
- Removal of dust, pollen, bird droppings and grime
- Visual inspection of panel condition
- Safe cleaning methods — no risk to seals or connections
- Improved energy output from cleaner panels
We service residential and commercial solar systems across Cairns North, Mareeba, Atherton, Mossman and the Tablelands. Whether you have a small rooftop array or a larger commercial setup, we can help. If birds are nesting under your panels, ask about our solar panel bird proofing service.
How We Clean Your Panels
We use purified water and soft brushes to hand wash each panel individually. This method removes stubborn buildup without scratching the glass surface or putting pressure on seals and connections. Unlike high-pressure washing, our approach is safe for all panel brands and will not void your manufacturer warranty.
Before we start, we do a visual check of your array for any obvious damage, loose wiring or cracked glass. If we spot anything, we let you know so you can follow up with your installer or electrician.
When to Clean Your Solar Panels
In Far North Queensland, we recommend a professional clean every 6 to 12 months. If your property is near trees, in a dusty area like the Tablelands, or you have noticed birds spending time around your array, more frequent cleaning may help maintain output. The end of dry season is a popular time to book — dust and pollen accumulate over the winter months and a clean before summer maximises generation during peak solar hours.

Solar Panel Cleaning FAQ
How often should solar panels be cleaned in Cairns?
In Far North Queensland, we recommend cleaning solar panels every 6 to 12 months. Properties near trees, in dusty areas like the Tablelands, or with bird activity may benefit from more frequent cleaning. The wet season can wash away some surface dust, but it also leaves behind pollen, bird droppings and organic residue that reduce panel efficiency.
Does cleaning solar panels really improve energy output?
Yes. Dirty solar panels can lose between 10 and 30 percent of their energy output depending on the level of buildup. Dust, pollen, bird droppings and grime block sunlight from reaching the photovoltaic cells. A professional clean restores full surface exposure and customers regularly report noticeable improvements in their energy generation after cleaning.
Is it safe to pressure wash solar panels?
No. High-pressure water can damage panel seals, coatings and electrical connections. We use a gentle hand wash method with purified water and soft brushes to safely remove buildup without risking damage to your panels or voiding manufacturer warranties.
