This is how solar panels can be kept clean – without using water

Solar power is expected to reach 10% of global power generation by 2030.
But the accumulation of dust on the solar panels can reduce output by 30%, while cleaning them uses about 10 billion gallons of water a year.
MIT engineers have developed a waterless cleaning method to remove dust on solar installations in water-limited regions.
The new system uses electrostatic repulsion to cause dust particles to detach and virtually leap off the panel’s surface. [Lire plus]
