How often do I need to clean my solar panels?
It is recommended in AS/NZS 5033 that solar panels should be checked for cleanliness and debris build up every three months. You may find that the rain over winter will keep any dust build up to a minimum. It’s likely over the warmer months when there hasn’t been any rain that panels will need dust and grime cleaned off them.
