The Custom Array Editor allows you to create custom block shapes for an inverter on the map design layout. These custom block shapes can be used throughout the layout by clicking the Update DC Capacity button (with Use Custom Arrays toggled on in Power Plant Parameters), or can be placed manually by clicking the Create button. When Exclude partial arrays is enabled, the automated layout uses only the custom array shapes and configurations as defined within the Custom Array Editor, which may result in lower capacities and land utilization since partial arrays cannot be automatically generated.
Custom Array Editor

​
Overview

The Custom Array Editor is organized into the following sections:
  1. Tab Navigation — Switch between Array Builder (create new arrays) and Array Editor (modify existing arrays).
  2. Array Preview — Visual representation of the custom array layout showing table arrangement with N-S road divider.
  3. Summary Statistics — Displays calculated values: Tables, MW AC, MW DC, DC/AC Ratio, Inverter kW, and Inverter kVA.
  4. DC Building Parameters — Configure array geometry, table dimensions, row counts, road widths, and orientation.
  5. AC Building Parameters — Configure inverter quantity and design derate.
  6. Action Buttons — Create, Cancel, Close, Exclude partial arrays, and Update DC Capacity controls.

1Array LabelText Field—User-defined name for this custom array configuration. Used to identify the array when placing it on the map or selecting it from the Array Editor.—
2Modules HighText Field—Number of modules stacked vertically (perpendicular to tracker axis or along the tilt direction for fixed systems).Table
3Modules WideText Field—Total number of modules along the tracker length or row direction.Table
4Table HeightText Fieldm / ftHeight of the table (collector band width) calculated from module dimensions and Modules High.—
5Table LengthText Fieldm / ftLength of the table calculated from module dimensions and Modules Wide.—
6Table SpacingText Fieldm / ftHorizontal gap between adjacent tables along a row.—
7Inverter QtyText Field—Number of inverters in this custom array block. Affects the total AC capacity calculation.Inverter
8Design DerateText Field—Fractional derate factor applied to the inverter rated power (0 to 1). A value of 0.95 means the inverter operates at 95% of rated capacity.Inverter
9Tables in Row (bottom)Text Field—Number of tables in each row of the bottom section of the array (below the E-W road).—
10Tables in Row (top)Text Field—Number of tables in each row of the top section of the array (above the E-W road).—
11Rows (left)Text Field—Number of rows in the left section of the array (west of the N-S road).—
12Rows (right)Text Field—Number of rows in the right section of the array (east of the N-S road).—
13N-S Road WidthText Fieldm / ftWidth of the North-South oriented access road that divides the array into left and right sections.—
14E-W Road WidthText Fieldm / ftWidth of the East-West oriented access road that divides the array into top and bottom sections.—
15GCR (%)Text Field%Ground Coverage Ratio — the ratio of module area to ground area. Higher GCR means denser packing. Linked to Row Spacing.Table
16Row SpacingText Fieldm / ftDistance between tracker rows (pitch). Automatically calculated from GCR and collector width, or can be manually entered.Table
17AzimuthText FielddegreesThe compass direction the modules face (0° = North, 90° = East, 180° = South, 270° = West). For trackers, this is the axis orientation. Accepts decimal values for precise orientation control.Fixed Tilt Arrays, Tracking Overview
18Racking AngleSliderdegreesThe tilt angle of the racking system. For trackers, this represents the current tracker angle position for the preview. For fixed-tilt systems, this is the fixed tilt angle.Fixed Tilt Arrays, Tracking Overview
19CreateButton—Places the custom array on the map at a location you specify. After clicking, you can position the array block on the map canvas.—
20CancelButton—Cancels the current array configuration without saving changes.—
21CloseButton—Closes the Custom Array Editor dialog and returns to the map interface.—
22Exclude partial arraysCheckbox—When enabled, the automated layout uses only the custom array shapes and configurations as defined in the Custom Array Editor. Partial arrays will not be automatically generated, which may result in lower capacity and land utilization.—
23Update DC CapacityButton—Applies the custom array configurations to the automated layout. Requires Use Custom Arrays to be toggled on in Power Plant Parameters. The layout engine will use these custom block shapes when filling the site boundaries.Power Plant Parameters
24Array Builder / Array Editor TabsTab Toggle—Toggle between Array Builder and Array Editor tabs. Array Builder (shown by default) is used to build full array blocks. Array Editor allows you to break the array block apart for rack-by-rack editing on the map UI.—
