    Abstract: Systems and methods for providing and controlling solar panel arrays are provided. The solar panel array may include one or more articulating joints that may provide variability in the arrangement of solar panels, which may allow the solar panel array to be distributed over varying types of underlying surfaces. The articulating joints may allow orientations of solar panels to be different relative to one another. The articulating joints may convey rotational force across the joints, so that a rotational force used to drive a first solar panel may also be conveyed across the joint and used to drive a second solar panel. The controls system may include row-specific semi-autonomous, or autonomous, controllers as well as controllers to interface with multiple rows. The controllers may include sensors to measure system power generation and basic operations aspects of the solar field to directly measure, or infer, module shading within the solar field.
