Visitors look at a solar tracker on Wednesday, July 27, 2011 in South Burlington, Vt. The project, 382 solar trackers composed of more than 9,000 individual panels, makes up Vermont’s largest solar installation - which was commissioned Wednesday. The 2.2 MW solar farm uses the Vermont-made AllSun Tracker – pole-mounted solar energy systems that use GPS and wireless technology to orient with the sun throughout the day to produce more energy than fixed solar units.
