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.
