Why Clean Your Solar Panels?
Clean panels don’t just look better — they work better. When dust, grime, bird droppings or mould build up on your solar panels, they block sunlight and reduce your system’s efficiency. In fact, dirty panels can lose up to 30% of their output.
Here’s why regular cleaning is worth it:
- Get more power for your dollar – maximise your system’s performance and see real savings on your energy bill
- Help your panels last longer – remove damaging buildup that can lead to wear and tear
- Avoid hot spots and breakdowns – cleaning reduces the risk of long-term damage and performance issues
- Keep your roofline looking sharp – a clean solar setup adds to your home’s overall appearance
- Protect your warranty – many installers require regular cleaning as part of their terms

Cleaning Methods We Use
Not all cleaning methods are safe for solar panels, which is why we use the most effective techniques that protect your system and get results. Our team understands how to clean panels without causing damage, voiding warranties, or leaving behind streaks.
Depending on your setup and how dirty your panels are, we use one or a combination of the following methods:
- Soft washing with low-pressure equipment and solar-safe cleaning agents — perfect for removing mould, algae, or organic build-up.

- Manual brushing with non-abrasive tools — used for tougher grime or hard-to-reach areas
The Best Time to Clean Your Solar Panels
Like anything exposed to the elements, solar panels build up grime over time — which can quietly reduce your energy output and cost you money. That’s why we recommend giving them a proper clean at least once or twice a year.
Here are the best times to schedule a clean:
- After autumn – clear away fallen leaves, dust and debris before they cause long-term buildup
- Before summer – make sure your panels are spotless and ready to perform during the sunniest, most productive time of year
- After storms or dust events – if you’ve had wild weather, your panels could be coated in dirt or organic residue that reduces efficiency
Regular cleaning means you won’t miss out on the power your system is capable of producing — especially when energy bills are climbing. A pre-summer or post-winter clean is the smart move for any solar panel owner.

Protect Your Warranty with Regular Solar Panel Cleaning
Most solar panel systems come with a 5 to 7-year warranty, but many homeowners don’t realise that these warranties come with strings attached. In most cases, you’re required to carry out regular cleaning and preventative maintenance — it’s written into the fine print of your contract.
While some installers offer a basic maintenance program, solar panel cleaning is usually excluded. That means if you leave your panels dirty and an issue arises, there’s a real risk your warranty claim could be denied.
At Glason, we help protect your investment. Our professional solar panel cleaning service keeps your system in top condition and ensures you’re meeting your maintenance obligations — giving you peace of mind and helping you avoid any nasty surprises later on.
If it’s been a while since your last clean, now’s the time to book.
