Panel Cleaning
Dirty panels can lose 15% of their output. Clean panels pay themselves off twice.
Adelaide dust, bushfire ash, bird droppings and tree sap reduce solar panel output by 5-15% over 12 months. Most manufacturer warranties require periodic cleaning. We refer professional roof-access cleaners insured for solar work.

The honest overview
Solar panel cleaning is not optional in Adelaide. Dust deposition, bushfire ash (especially summer), bird droppings, and pollen reduce output significantly. Annual cleaning is the standard recommendation; properties under trees may need 6-monthly cleans. Most professional cleaners use deionised water and soft brushes - never pressure wash with mains water.

Panel Cleaning: questions
Can I clean the panels myself?
Technically yes for ground-mount, but rooftop work requires proper safety equipment and insurance. Most home insurers exclude rooftop falls. Cleaning by hose alone leaves mineral residue that reduces output further.
How often should I clean Adelaide solar panels?
Annually for most homes; biennially if you are inland away from tree cover and dust. After bushfire season is the most important clean.
Will rain clean the panels enough?
Rain helps with dust but does not remove bird droppings, sap, or burnt ash. A measurable performance gap usually appears within 12 months of relying on rain alone.
