Customize Presets for each of the array types
The array presets start with selecting a default module. If you are primarily using one type of module at a time for all installs, this would be worth doing to save time in design.
Orientation - Select if modules will fill in portrait or landscape.
Height - Determine how high off of the segment the modules will be. Current default should be 6 inches (except for ground mounts) to account for racking.
Module Spacing - Distance between modules within an array. Column and Row can be set to different amounts, moving in 1" intervals starting at 0".
Array Spacing and Layout - Primarily for ground mounts, this feature helps divide large areas into smaller array groups for design/terrain purposes, allowing you to set their size and spacing.
In the GIF above, I have saved my settings so that ground mounts will appear in groups of 5x3 arrays that have 3' of space side by side, and 7' of space front to back.
