Geographic Influences

Where you live matters a lot for cleaning. Places with lots of dust or pollution need more cleaning. Coastal areas deal with salt and need frequent washing. If you’re near trees, leaves and bird droppings call for regular cleaning too. Know how your area affects your panels to set a good cleaning schedule.
