We have several methods for cleaning solar panels. One is using a soft foam or bristle brush and gently washing the panels. The other is using a special attachment that goes on the water blaster arm. This creates a gentle fan of water to get them clean and shiny.
We can also use our water purifying system as this really helps to give a very clean spot free result. The water purifying system takes the calcium and any other minerals out of the water for that extra shiny, streak-free clean.
Washing your solar panels a couple of times of year helps to ensure cost savings through better efficiency of the solar panel. As an example, you could be losing around 20% energy if you only wash your solar panels once a year and 35% energy loss if you only wash them every two years.
The percent can increase or decrease depending on the environmental factors that surround the roof. For example, if the building is close to a gravel road the panels will get a dust build-up. If it is close to a high traffic area, pollution from vehicles will coat the solar panels. If there are tall trees the residue from the trees can land on the solar panels and affect the efficiency.
We don’t recommend it. Solar panels are slippery, often hard to reach, and can be easily scratched or damaged with incorrect tools. It’s safer — and more effective — to let trained technicians handle it.
Typically, every 6 to 12 months. If you live near the coast, in a rural area, or anywhere with dust or high pollen, you may benefit from more frequent cleaning to maximise output.
We’ll inspect your panels before we begin. If lichen is present, we’ll discuss a gentle treatment approach that removes it safely. Regular cleaning helps prevent lichen from taking hold in the first place.
No. Our method is in line with most manufacturers’ warranty recommendations. In fact, it can help preserve the lifespan of your system by preventing lichen and dirt buildup from degrading the surface over time.
We use either a pure water-fed pole or a soft-bristle brush system depending on your setup. No harsh detergents, no pressure washing — just safe, chemical-free cleaning that protects delicate surfaces and electrical components.
Dirty panels can’t absorb as much sunlight, which directly affects your energy output. Dust, pollen, lichen, and grime reduce efficiency over time. Regular cleaning restores performance and helps protect your solar investment.
