Solar Panel Cleaning and Inspection Before Winter Sets In
Here’s why pre-winter is the most ideal time to give your solar panels some tender loving care—and how tradies can get the job done.

It’s time to give your home a bit of TLC before winter rolls in. One area that often flies under the radar? Your solar panels.
Keeping your solar system in top shape is essential, and autumn is the perfect time to do it. A thorough cleaning and inspection can boost efficiency, catch small issues before they become costly, and ensure your panels continue to perform optimally during those cloudy winter months.
Here’s why now’s the time to give your solar panels some attention—and how to get the job done right.
Why Clean Your Solar Panels Before Winter?
You wouldn’t drive around with a dirty windscreen and expect great visibility, would you? The same principle applies to your solar panels. When panels get covered in dirt, dust, bird droppings, leaves, or even coastal salt spray, their efficiency takes a hit.
Autumn in Australia brings falling leaves, increased bird activity, and higher moisture levels in the air — all of which can lead to a buildup on your panels. Then, come winter, with shorter days and lower sun angles, every bit of sunlight counts. Dirty panels can lose up to 20% of their energy output, and that’s a hit to your wallet when your power bills start creeping up.
Cleaning them before winter ensures you’re getting the most out of every ray of sunshine.
The Importance of a Professional Inspection
Cleaning is one thing, but an inspection is where the real peace of mind kicks in. A trained tradie can spot issues you might not notice until it's too late, like:
-
Loose or cracked panels
-
Corroded wiring
-
Water damage
-
Faulty inverters or connectors
-
Animal nesting (yes, possums and birds love solar setups)
Think of it like a health check-up for your solar system. Catching problems early can save you thousands down the line, especially since winter storms and heavy rains can exacerbate small issues.
DIY vs. Hiring a Professional
We get it — Aussies love a bit of DIY. But when it comes to solar panel cleaning and inspection, it’s often best left to the pros.
Here’s why:
-
Safety first: Climbing up on the roof is risky business, especially if it’s steep or slippery. Professionals have the right gear and know-how to stay safe.
-
Proper tools: You can’t simply hose down your panels or use a pressure washer. Tradies use specialised cleaning equipment that gets the job done without damaging the glass or coatings.
-
Know what to look for: An experienced eye can pick up on wear and tear that an untrained one might miss, helping you avoid unexpected system failures later.
Hiring a qualified solar panel cleaner or inspector through a trusted platform like ServiceSeeking.com.au means you’re getting someone who knows what they’re doing, and who comes with ratings and reviews from other Aussie homeowners. You can compare quotes quickly, check credentials, and book with confidence.
What to Expect From a Solar Panel Service
A typical solar panel cleaning and inspection includes:
-
A full surface clean of the panels with purified water (no chemicals or residue)
-
Visual inspection of the panels and mounting system
-
Check for signs of corrosion, cracks, or warping
-
Electrical checks for voltage output and inverter performance
-
Photos and a brief report on the condition of your system
It typically takes under two hours for an average-sized system, and the benefits—both in terms of performance and peace of mind—are well worth it.
How Often Should You Get Panels Cleaned?
Most solar systems benefit from a professional clean once or twice a year, depending on your location. If you're near the coast, in a bushy area, or in a place with a lot of birds, you may need to clean them more frequently.
Inspections are typically recommended annually or after a major weather event, such as a hailstorm.
Autumn is the sweet spot: the weather is mild, and it gives your panels the best shot at performing optimally through winter.
