A Staff of Robots Can Clean and Install Solar Panels Oct 17 2013

In a dusty yard under a blistering August sun, Rover was hard at work, lifting 45-pound solar panels off a stack and installing them, one by one, into a concrete track. A few yards away, Rover’s companion, Spot, moved along a row of panels, washing away months of grit, then squeegeeing them dry.

But despite the heat and monotony — an alternative-energy version of lather-rinse-repeat — neither Rover nor Spot broke a sweat or uttered a complaint. They could have kept at it all day.

That is because they are robots, surprisingly low-tech machines that a start-up company called Alion Energy is betting can automate the installation and maintenance of large-scale solar farms. . . .
