Solar panels have gotten so cheap that installers are seeking new ways to push down the cost per clean kilowatt. One answer: Get rid of the humans !
Behind a high fence in Menlo Park, Calif. a gray, tuna-shaped robot glides on a monorail around 20 solar panel arrays attached to steel poles, like WALL-E on a Disneyland ride. The Solbot, made by startup QBotix, stops at each array and extends a cylindrical arm to adjust the angle of the photovoltaic panels so they capture the most amount of sun as it moves across the sky and through the seasons.
