Trusted Solar Panel Cleaners in Sydney
Boost your solar efficiency by up to 30% with professional cleaning services. Trusted by Sydney homeowners and businesses.
Is Your Solar System Underperforming?
You could be losing up to 30% of your solar output — and over $1,200 a year — without even knowing it.
Most Australian homeowners assume their solar panels are self-maintaining. But dirt, pollen, bird droppings, and grime build up fast — especially in areas with strong sun and coastal wind.
This buildup blocks sunlight and reduces the efficiency of your system. In fact, a dirty panel array can lose 20–30% of its output.
Regular professional cleaning helps:
- Prevent long-term system damage
- Maximise your energy output
- Keep your warranty valid
- Extend the life of your solar system

Understand why cleaning matters, how we do it, and the benefits you'll experience
Why Dirty Solar Panels Are a Problem
Reduced Energy Output
Dirt, dust, and debris block sunlight from reaching your panels, reducing energy production by up to 30%.
Hot Spots & Damage
Bird droppings and concentrated dirt create hot spots that can permanently damage your panels and reduce lifespan.
Warranty Risks
Most manufacturers require regular cleaning to maintain warranty coverage. Neglect can void your protection.
Why Rain Isn't Enough
Rain Leaves Residue
Rain water contains minerals and pollutants that dry and leave a film on your panels.
Stubborn Substances Remain
Bird droppings, tree sap, and pollen are sticky and won't wash away with rain alone.
Costs You Money
Relying on rain means accepting lower energy production and paying higher electricity bills.

Frequently Asked Questions
Everything you need to know about our solar panel cleaning services
Why should I pay for solar panel cleaning?
Great question. It's not just about saving a few hundred dollars in electricity — it's about protecting your solar investment. Solar systems cost $15,000–$30,000+. Dirt, dust, pollen, and grime can cut efficiency by up to 30%. Long-term buildup leads to wear and tear, hot spots, and even voided warranties. You pay a mechanic to maintain your car. This is how you maintain your solar system — and keep it running like the day it was installed.
How often should I clean my solar panels?
For optimal performance, we recommend cleaning your solar panels 2-4 times per year, depending on your location and local conditions. Areas with high pollution, near the coast, or with significant bird activity may require more frequent cleaning.
Will cleaning really make a difference to my energy production?
Absolutely. Independent studies show that dirty solar panels can lose 15-30% of their efficiency. Our customers typically see a 20-25% increase in energy production after a professional clean.
Is it safe to clean solar panels myself?
While it's possible, we don't recommend it. DIY cleaning risks personal injury from working at heights, potential damage to expensive panels, and often doesn't achieve professional results. Our technicians are fully trained, insured, and use specialized equipment.
What cleaning methods do you use?
We use a combination of purified water technology and soft brushes specifically designed for solar panels. Our cleaning solutions are 100% biodegradable and won't damage your panels or void warranties.
How long does the cleaning process take?
A typical residential system (10-20 panels) takes about 1-2 hours to clean thoroughly. Commercial systems vary based on size and accessibility.
