Abstract
A solar-tracking photovoltaic array is described. The photovoltaic array includes mounting hardware configured to rotate photovoltaic modules associated with the photovoltaic array about one or more axes. In some embodiments, the photovoltaic modules can be coupled to a torque tube oriented in a substantially North-South direction. An orientation motor can then rotate one end of the torque tube in a manner that causes the photovoltaic modules to track the sun. The photovoltaic array can also include a locking mechanism that secures another end of the torque tube during times in which the orientation motor is not rotating the torque tube.
