A pneumatic control unit configured to inflate a first and second set of bellows with fluid from a pneumatic fluid source via a pneumatic circuit, the first and second set of bellows associated with one or more pneumatic actuators. The pneumatic control unit determines a target configuration of the actuators based on a determined current position of the sun; determines a current configuration of the actuators; determines a difference between the determined current configuration and target configuration of the actuators; determines that the difference between current configuration and the target configuration of the actuators is outside of a tolerance range; and actuates the actuators toward the determined target configuration by at least one of inflating the first or second set of bellows with fluid from the pneumatic fluid source via the pneumatic circuit.

Solar tracker control system and method

An actuator that includes a bottom plate, a top-plate, and a first and second hub assembly extending between the bottom and top plates. The actuator can further include a first and second bellows disposed on opposing sides of the hub assemblies, the first and second bellows each extending between and coupled to the top plate and bottom plate. The actuator can also include a plurality of washers disposed between the top and bottom plates, with each of the washers coupled to the first and second hub assembly, a first set of the plurality of washers surrounding the first bellows and a second set of the plurality of washers surrounding the second bellows.
