Abstract: Space frames incorporating flanged chords and struts with receiving spaces configured to receive at least portions of the chord flanges without the need for connector nodes that are separate from the chords. For example, a space frame can include a strut, a first chord, and a second chord. The first chord can have a first flange and a second flange fixed relative to the first flange. The second chord can have a third flange. The strut can include receiving spaces configured to receive portions of the first flange and the third flange. The strut can be secured relative to the first and second chords and the space frame can support a reflective surface configured to focus electromagnetic radiation.

Abstract: A solar collector controller that can process solar field control commands can include a network interface that can receive a variable-length data packet with a collector controller. The collector controller can control one or more solar collectors. In addition, the variable-length data packet can include a header segment identifying a command to be performed by the collector controller and a data segment having one or more parameters associated with the command. The data segment can have a length that depends on a type of the command. Moreover, the solar collector controller can include a processor that can execute the command in response to receiving the data packet.

Abstract: A system for controlling a solar field can include a field control server that communicate with a plurality of solar collector controllers installed in a solar field. The field control server can include one or more processors that can implement a user interface module that can provide a solar field user interface having a plurality of user interface controls. Each of the user interface controls can represent one or more solar collector assemblies. User selection of one of the user interface controls can cause the field control server to send a command to one or more collector controllers associated with the selected one or more solar collector assemblies. Further, the system can include a customization module that can provide functionality for a user to customize the solar field user interface to accommodate changes in a number of the solar collector controllers installed in the solar field.

Abstract: A system for causing a solar collector to track the sun can include a collector controller that can control one or more solar collectors in a solar field, where the collector controller has one or more processors. The collector controller can estimate a sun angle, determine an angle of the one or more solar collectors with respect to the sun based at least partly on an inclination angle of the one or more solar collectors, and compare the estimated sun angle with the angle of the one or more solar collectors to determine a desired movement of the one or more solar collectors. Further, the collector controller can actuate the motor to effectuate the desired movement until the angle of the one or more solar collectors is within a hysteresis value within a virtual track deadband.
