SOLAR NIGHT ROBOTS!

Israel, Arava Valley: Each night, in the world's first self-cleaning solar 20-acre facility, a 100 Israeli-made robots brush and clean the hundreds of solar panels which generate 9 million kilowatt hours of electricity per year. "It’s a technical breakthrough," said Eran Meller, CEO of Ecoppia, which built the robot cleaning crew,"which should increase production of the solar panels by as much as 35%."
