The system is powered with electricity from the electrical panel in the house. There is very little power required for tracking and the system uses less than 1% of the power it produces.
The GPS unit inside the tracker control box knows the tracker's location as well as the time. Knowing its location and the time, the tracker knows exactly where the sun is at any given moment. The tracker uses its hydraulic drive to position the array to directly face the sun. As the sun moves, the tracker will periodically reposition the array. It is not dependent on clock time for any particular time zone and thus will not be impacted by any weather events or the change to daylight savings time.
The tracker uses standard hydraulic fluid in its hydraulic system to make it move. The motor that runs the system makes about as much noise as your refrigerator.
They are designed for a 25-year lifespan, and have a 10-year parts warranty. Please see our Limited Warranty for more information.
Most homeowner policies cover "other structures" up to a certain percentage of your overall policy. Check with your insurance agent about tracker coverage.
