Automatic solar panel cleaning system removes dirt and dust, boosting efficiency by allowing panels to absorb more solar energy. 📸: Instagram/ bharat_solar_cleaning_system | Interesting Engineering

A new cleaning method could remove dust on solar installations in water-limited regions, improving overall efficiency. Read more about how the new system uses electrostatic repulsion to cause dust particles to detach and virtually leap off the panel’s surface, without the need for water or brushes. http://mitsha.re/caUj50IiA8R Video: Melanie Gonick/MIT | Massachusetts Institute of Technology (MIT)
