FAQs about Where is the solar cell most likely to get dirty
What happens if solar panels get dirty?
Solar panels can lose up to 30% of their efficiency when they are dirty. If a solar panel is covered in dirt, dust, or bird droppings, it won't be able to produce as much power as it normally would. When solar panels get dirty, they don't generate as much electricity.
