A photovoltaic (PV) arrayAn interconnected system of PV modules that function as a... that follows the path of the sun to maximize the solar radiation incident on the PVSee photovoltaic(s). surface. The two most common orientations are: (1) one axis where the array A solar array is a collection of solar panels wired together to... tracks the sun east to west; and (2) two‐axis trackingA photovoltaic array tracking system capable of rotating independently about... where the array A solar array is a collection of solar panels wired together to... points directly at the sun at all times. Tracking arrays use both the direct and diffuse sunlight. Two‐axis trackingA photovoltaic array tracking system capable of rotating independently about... arrays capture the maximum possible daily energy.
