A solar tracker system includes a photovoltaic panel and an actuator coupled to the photovoltaic panel and configured to actuate to rotate the photovoltaic panel around a base. A controller communicatively coupled to the actuator is configured to detect a direction from which wind is incident on the photovoltaic panel. Based on the direction from which wind is incident on the photovoltaic panel, the controller adaptively controls the actuator to set a stow position of the photovoltaic panel.

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.

A solar tracking sensor includes lens and four fibers respectively representing four directions installed in a lens barrel to serve as a fine-positioning daylighting module, and four groups of fibers installed on the side of the lens barrel to serve as a coarse-positioning daylighting module. A circuit board and four photocells are installed at the bottom of a cassette. Each photocell is connected to fine positioning fibers located in the same direction as the photocell, and is connected to coarse positioning fibers located in a direction diagonal to the direction of the photocell. By using a daylighting method of combining fine-positioning daylighting and coarse-positioning daylighting, the number of the photocells is reduced, the design of the circuit board is simplified, and costs are reduced; moreover, because the coarse-positioning daylighting module can collect sunlight in a wide-angle range, the tracking angle range of the sensor is enlarged.

A solar tracker system including a tracker apparatus including a plurality of solar modules, each of the solar modules being spatially configured to face in a normal manner in an on sun position in an incident direction of electromagnetic radiation derived from the sun, wherein the solar modules include a plurality of PV strings, and a tracker controller. The tracker controller includes a processor, a memory, a power supply configured to provide power to the tracker controller, a plurality of power inputs configured to receive a plurality of currents from the plurality of PV strings, a current sensing unit configured to individually monitor the plurality of currents, a DC-DC power converter configured to receive the plurality of power inputs powered from the plurality of PV strings to supply power to the power supply, and a motor controller, wherein the tracker controller is configured to track the sun position.

A solar tracker system comprising a plurality of on sun trackers and a plurality of off sun tracker. Each tracker is selectively adjusted to achieve a desired power output of the solar power plant system in an example.
