Tracking Array

A photovoltaic (PV) array that follows the path of the sun to maximize the solar radiation incident on the PV surface. The two most common orientations are: (1) one axis where the array tracks the sun east to west; and (2) two‐axis tracking where the array points directly at the sun at all times. Tracking arrays use both the direct and diffuse sunlight. Two‐axis tracking arrays capture the maximum possible daily energy.
