As part of or in addition to classification, an embodiment may include systems and methods to create, associate, and edit intrinsic and extrinsic properties to these objects. A design engine may apply of design rules to the features described above to generate one or more solar collectors installation design alternatives, including generation of on-screen and/or paper representations of the physical layout or arrangement of the one or more design alternatives. Some embodiments may provide viewing, creating, and manipulating of multiple versions of a solar collector layout design for a particular installation worksite. The use of versions may allow analysis of alternative layouts, alternative feature classifications, and cost and performance data corresponding to alternative design choices. Version summary information providing a representative comparison between versions across a number of dimensions may be provided. ## Claims ### Claim 1 An apparatus for designing a solar collector installation, comprising: at least one processor configured to: generate a displayable representation of an installation worksite on a user interface, the representation comprising feature properties corresponding to physical features of the worksite and a solar collector installation layout including solar collectors arranged on at least one surface feature of the worksite; generate a plurality of differing versions of project state information of the worksite, wherein each of the differing versions includes design preferences, feature properties, and/or project properties, wherein each of the differing versions corresponds to an alternative solar collector installation layout, wherein the alternative solar collector installation layout for each of the differing versions results from differences between the design preferences, feature properties, and/or project properties, and wherein each of the differing versions shares at least some of the project state information; receive a first user input from the user interface indicating a change to the design preferences, feature properties, and/or project properties, the change being recorded by taking a snapshot of one or more of the differing versions; and receive a second user input from the user interface indicating undoing the change to the design preferences, feature properties, and/or project properties based on the snapshot. ### Claim 2 (depends on 1) The user interface of claim 1, wherein the shared project state information includes classifications of at least some geometric objects as instances of a feature type. ### Claim 3 (depends on 1) The user interface of claim 1, wherein the design preferences of a first version differs from the design preferences of at least one other version. ### Claim 4 (depends on 1) The user interface of claim 1, wherein the feature properties of each of the differing versions includes geometric object information. ### Claim 5 (depends on 1) The user interface of claim 1, wherein each of the differing versions includes feature classification information. ### Claim 6 (depends on 1) The user interface of claim 1, wherein the at least one processor is configured to create a new version of project state information. ### Claim 7 (depends on 6) The user interface of claim 6, wherein the at least one processor is configured to allow a user to make changes to the design preferences and feature properties corresponding to the new version that are not reflected in the design preferences and feature properties corresponding to any version created before the new version. ### Claim 8 An apparatus for designing a solar collector installation, comprising: at least one processor configured to: generate a displayable representation of an installation worksite on a user interface, the representation comprising feature properties corresponding to physical features of the worksite and a solar collector installation layout including solar collectors arranged on at least one surface feature of the worksite;

generate and display a comparative representation of the differing versions of project state information in the user interface; receive a first user input from the user interface indicating a change to the design preferences, feature properties, and/or project properties, the change being recorded by taking a snapshot of one or more of the differing versions;
