Egyptian scientists developed a self-cleaning system for solar panels. This system is based on how tree leaves shed dust. When dust covers solar panels, it blocks sunlight and lowers energy production.
The new panels use vibrations to clean themselves. They shake off dust twice a day. This design can save money on cleaning solar panels every month. The cleaning cost is lower because panels need cleaning less often.
