Expert Solar Panel Cleaning in Sydney

Solar panels save you money on energy bills and reduce your carbon footprint. If you want to make the most of this investment, you need to keep your solar panels clean and well-maintained. Solar panels are continuously exposed to the elements. Over time, dirt and dust can accumulate on the panel’s surface, blocking sunlight and minimising energy output.

Moreover, bird droppings, tree sap, and smog can also leave ugly and persistent stains on your solar panels. Yes, rain or a garden hose helps wash away the dirt, but it is not enough to remove those layers of grime. So, you need to hire an expert who has the experience, expertise, and equipment to handle such stubborn blemishes. Why look further when Billingsly Cleaning Services has it all?

We offer professional solar cleaning services to homes and businesses in Penrith, the Blue Mountains, Hornsby, Homebush, and Camden. Our skilled technicians ensure streak-free cleaning for maximum efficiency and energy output. With more than 15 years of combined experience, we are familiar with the safety protocols and make sure to clean the panels without scratching the glass or damaging the delicate photovoltaic cells.

Amazing pressure washing service, good attention to detail and didnt damage any of the surfaces like some tend to do. Highly recommended!
Billingsly Cleaning Services handled my end of bond clean for a 2 bed, 2 bath apartment and absolutely nailed it. The place looked immaculate. Every surface was spotless, the bathrooms sparkled, and they didn’t miss a thing. The property manager was impressed too, which says it all. Super professional, reliable and worth every cent. Highly recommend if you want your bond back without stress!
Stephen did an amazing job cleaning our business driveway & building.
He was very professional.
Thanks Stephen
Stephen cleaned my roof that was covered in lichen. He treated it chemically then washed it. The lichen turned brown so it’s definitely dead and I’m happy with it finally getting done as my roof was knocked back by another roof cleaner as it was too slippery to walk on- not for Stephen he painstakingly finished it after 2days and I couldn’t be happier. Thank you Billingsly Cleaning Services.
Billingsly cleaned my home in Lethbridge Park, and I can't recommend them enough - Rachel was an absolute pleasure to speak with and was very flexible with making my booking. The lovely cleaners were all unpacked ready to start at our agreed upon time, and even made sure to tackle all of the pain spots I can't do myself.
Thank you for your professionalism, I will be using this service again! Priceless.

Would recommend to everyone
The best cleaning company we have ever worked with! We used Billingsly for our end of lease clean and it was like walking into a brand new home once they were done. Staff were incredibly friendly and easy to deal with, and the quality of work was unmatched. Will definitely be using them for all our cleans in the future and referring them to everyone we know. Highly recommend!
Really prompt response at a great price. Very professional and great communication.
The guys at Billingsly Cleaning Services got me out of a jam and saved me. When my carpet cleaning booking with a company I originally booked with cancelled on me, I had no options left as I had an inspection coming up. I called Steve and he was happy to help me. He aorked in with my schedule and time frame and took the time and care to bring my carpet back to life (I didn’t think it was possible with this carpet). Highly recommended and very well priced for the quality of work!

Why Professional Solar Panel Cleaning is Important

You may not realise, but dirt build-up can badly impact your solar panel’s performance. Yes, professional solar cleaning has a cost, but it pays off in the form of improved energy output. As your trusted local experts, we aim to get you the highest return on your investment with our reliable solar panel cleaning services. You will be more than happy with the results, as it will ensure

  • Maximum Energy Output
    We remove the layers of grime so your panel can absorb maximum sunlight, restoring up to 25% of lost energy output. This makes the cost of cleaning negligible in just a few months.
  • Warranty Protection
    Using harsh chemicals, tap water (which leaves mineral deposits), or a high-pressure washer can damage the surface, voiding your warranty. That’s why we use safe, non-toxic cleaning solutions.
  • Safety and Compliance
    Our cleaners are fully insured and police-checked; they are also trained in working at heights. So, you don’t have to worry about any damages or compliance issues.
  • Reduced Energy Bills
    We make sure to do the cleaning job so well that you will see the results within months in the form of reduced energy bills.

Streak-Free Cleaning, Maximum Protection

We put great emphasis on safety in all of our services, so all our cleaners are qualified and insured. We ensure to execute each cleaning job with professionalism and care. So, you can be assured that our professional experts will use safe methods and equipment to minimise any potential risks. Choosing us for your solar panel cleaning is a worthwhile investment, as it will boost their operational efficiency and durability.

The key to a perfectly clean, damage-free solar panel is the quality of water used for cleaning. We understand that tap water contains calcium, magnesium, and other minerals. When dried in the sun, these minerals leave behind stubborn white spots and streaks on your solar panel, the exact deposits you were trying to remove in the first place.

We use pure, mineral-free water for cleaning that acts like a magnet, pulling contaminants and dissolved solids from the panel surface. When the panels dry, the water evaporates completely, ensuring streak-free cleaning. For even better results, our cleaners use soft, synthetic brushes to safely scrub away dried bird droppings.

Moreover, we don’t use harsh chemicals, so there is no risk of damage to the photovoltaic cells. Get in touch with us today to book your solar panel cleaning service.

Our Efficient Solar Cleaning Process

We have designed a process to ensure safe, efficient, and reliable solar cleaning, whether it’s your home or commercial property.

  • Safety Assessment
    Our technicians conduct a ladder and roof access assessment, establish safety barriers, and turn off your solar system before starting the cleaning work. We also check the manufacturer’s guidelines to protect your warranty.
  • Removal of Loose Debris
    We rinse the panel with purified water to remove loose debris from the panel so we can inspect the surface for any pre-existing damage, such as chipped glass.
  • Soft Scrubbing
    Next, we gently scrub the surface of each panel to lift stubborn grime, bird droppings, and deep-seated dust.
  • Final Rinse
    Our cleaners use mineral-free water to wash away all contaminants and residues after scrubbing, ensuring a streak-free finish.
  • Secure Exit
    We pack up our equipment, clean the area, and give you a report on the condition of your panels before leaving.

Tips for DIY Cleaning

  • Avoid cleaning in direct sunlight, as the panels can get extremely hot.
  • Never use harsh chemicals or abrasive cleaning pads.
  • Don’t use pressure washers.

If cleaning your solar panel looks like a lot of work or you have safety concerns, leave the job to professionals!

Frequently Asked Questions

Does rain clean the solar panels efficiently?

Rain is a natural cleaner, but it only washes away light debris and loose dirt. You will need professional solar cleaning services to remove stubborn grime and sticky residues, like bird droppings, airborne pollution, and sap.

How frequently should I have my solar panels cleaned?

We recommend homeowners get their solar panels cleaned every 6 to 12 months to prevent dirt build-up. Regular cleaning and maintenance will help solar panels absorb maximum sunlight and perform optimally.

Do you step on the panels during the cleaning process?

No, we use specialised water-fed pole systems that allow us to clean the panel from the ground or secured roof access points. This way, we avoid scratching the glass or placing stress on the panel.

Are you trained in roof work?

Yes, our solar panel cleaning technicians have the required training and certifications to work at heights. We use safety harnesses and take all precautions as per the WHS laws.

Is tap water safe for cleaning my solar panel?

No, tap water leaves mineral deposits when it dries, creating a film that streaks the glass and reduces light transmission. That is why we use pure water for solar panel cleaning.

Do you check the wiring or mounting systems?

We focus on cleaning the glass surface. Our cleaners will report any obvious damage, like broken glass or loose wiring, but we don’t perform system checks or repairs.
