Abstract
A system is provided. The system 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 the rotational mechanism. The controller is programmed to store a plurality of positional information and a shadow model for determining placement of shadows based on positions of objects relative to the sun, determine a position of the sun at a first specific point in time, retrieve height information for the tracker and at least one adjacent tracker, execute the shadow model based on the retrieved height information and the position of the sun, determine a first angle for the tracker based on the executed shadow model, and transmit instructions to the rotational mechanism to change the plane of the tracker to the first angle.
