Why do solar panels need cleaning?
Answer: To improve your solar panel’s performance and reliability! Let us explain…
Your solar panels will be installed with the correct amount of tilt, which will mean they will generally self-clean by taking advantage of rain running across them to keep clean. However, here in Australia, we can experience particularly long periods of drought, during which dust build-up, bird’s droppings and other air pollution will accumulate on your solar panels over time.
Also, if you have trees close by your solar panels, particularly deciduous ones, these will drop leaves onto your panels as well as attract birds.Each of the above-mentioned build-ups can affect the electric generation of your solar panels per module. After all, it makes sense that solar panels will work most effectively when their view to the sun is not obstructed by dirt buildup and other debris
How often should I clean my solar panels?
As a general rule, considering our harsh Australian climate, you want to aim to clean your solar panels at least every six months.
However, if we are experiencing extreme climate conditions for a prolonged period of time such as fires, dust storms or excessive rainstorms, then you may need to clean your panels more often.
Locations that may require more frequent cleaning
If your home is positioned within close range of a highway or a construction site – both of which will produce excess airborne debris, you will need to practice more frequent solar panel cleaning.
Also, homes within coastal areas such as many of our beautiful suburbs within the Shoalhaven should consider the buildup of marine layer residue, which can leave an obstructive film that too will require more frequent cleaning.

Plan for safety first
Before jumping up on your roof with your cleaning gear and good intentions, stop and consider your safety first. Basically, nobody should be up on their roof without being attached to a safety harness or wearing a hard hat. Check out some information about working safely at heights here.
TIP: Choose a cool day to get up on your roof and clean, as roofs generally hold a lot of heat which can make your task a whole lot harder!
