Solar panels should be cleaned regularly so they can produce as much clean energy as possible

Clean solar panels are going to deliver a much higher energy output than dirty panels. Dirt, dust and particularly bird droppings which don’t wash off easily with rain can build up minimising the amount of sunlight that the solar panels receive. Areas and locations that may require more frequent solar panel cleaning include:
• Coastal – properties located near the coast are prone to the build up of
a salty film that can decrease the amount of sunlight that the solar
panels receive.
• Inner city and greater Adelaide – these areas are prone to dust and dirt
particularly those properties that are located near main roads where
the dust and dirt from vehicles can build up more quickly and reduce
the performance of your panels.
• Low rainfall locations – as South Australia is the driest of the Australia states it is less likely that your panels will be naturally cleaned by rain.
