Introducing robots that tilt solar panels
Inside a fenced-in yard in an industrial corner of Menlo Park, Calif. -- a few miles from the venture capitalists on Sand Hill Road, and the west span of the Dumbarton Bridge that stretches over the bay -- robots have quietly been tending to two rows of solar panels. Every 40 minutes the robots adjust the tilt of the panels to face the sun as it moves across the sky -- equipped with sensors, GPS and a wireless connection, the robots also continuously report back data about the panels to the solar project owner.
