Abstract
A system and method for array level terrain based backtracking includes a tracker configured to collect solar irradiance and attached to a rotational mechanism for changing a plane of the tracker and a controller in communication with a rotational mechanism. The controller is programmed to determine a position of the sun at a first specific point in time, retrieve height information, execute a shadow model based on the retrieved height information and the position of the sun, determine a first angle for the tracker; collect an angle for each tracker in a plurality of trackers in an array; adjust the first angle based on executing the shadow model with the first angle and the plurality of angles associated with the plurality of trackers; transmit instructions to the rotational mechanism to change the plane of the tracker to the adjusted first angle.
