Proudly Serving PERTH
Fremantle’s coastal location means solar panels are regularly exposed to salt carried in from the ocean. Over time, this salt can settle on the glass and combine with dust, dirt and bird droppings to create a layer of buildup that reduces solar performance.
Unlike inland suburbs, coastal areas such as Fremantle often need more regular solar panel cleaning because of the extra environmental exposure. Even if panels only look slightly dirty from the ground, residue on the surface can still affect how much sunlight reaches the cells.
Regular cleaning helps keep your panels clear and supports consistent energy production throughout the year.
Solar panels rely on direct sunlight to operate efficiently. When dirt and residue build up on the surface, they reduce the amount of light that can reach the cells underneath.
This can lead to:
• lower energy production
• reduced solar efficiency
• less return from your system
• greater reliance on grid electricity
In a coastal suburb like Fremantle, salt residue can also cling to the glass and become more difficult to remove if left untreated.
Professional solar panel cleaning helps remove this buildup safely and restore the surface so your system can perform at its best.
Purified Group uses specialist equipment and purified water systems designed specifically for solar panel cleaning.
Our process includes:
• safe access to the roof and panel area

Because Fremantle is a coastal suburb, solar panels may need cleaning more often than in inland areas. Regular professional cleaning helps prevent salt and dirt buildup from reducing performance.
Yes. Salt carried in from the ocean can settle on the surface of solar panels and reduce how much sunlight reaches the cells.
Rain can remove some loose dust, but it usually does not remove salt residue, bird droppings or stubborn grime properly.
Yes. Professional cleaning helps remove buildup that can reduce solar efficiency and affect long-term energy savings.
Cleaning solar panels yourself can be risky, especially on roofs affected by coastal moisture, steep pitch or difficult access. Professional cleaning is usually the safer option.
