Custom Array Editor

Create custom block shapes for inverter arrays to use in automated or manual map layout design

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.

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.

User Inputs

#	Input	Type	Units	Description	Related Documentation
1	Array Label	Text 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.	—
2	Modules High	Text Field	—	Number of modules stacked vertically (perpendicular to tracker axis or along the tilt direction for fixed systems).	Table
3	Modules Wide	Text Field	—	Total number of modules along the tracker length or row direction.	Table
4	Table Height	Text Field	m / ft	Height of the table (collector band width) calculated from module dimensions and Modules High.	—
5	Table Length	Text Field	m / ft	Length of the table calculated from module dimensions and Modules Wide.	—
6	Table Spacing	Text Field	m / ft	Horizontal gap between adjacent tables along a row.	—
7	Inverter Qty	Text Field	—	Number of inverters in this custom array block. Affects the total AC capacity calculation.	Inverter
8	Design Derate	Text 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
9	Tables in Row (bottom)	Text Field	—	Number of tables in each row of the bottom section of the array (below the E-W road).	—
10	Tables in Row (top)	Text Field	—	Number of tables in each row of the top section of the array (above the E-W road).	—
11	Rows (left)	Text Field	—	Number of rows in the left section of the array (west of the N-S road).	—
12	Rows (right)	Text Field	—	Number of rows in the right section of the array (east of the N-S road).	—
13	N-S Road Width	Text Field	m / ft	Width of the North-South oriented access road that divides the array into left and right sections.	—
14	E-W Road Width	Text Field	m / ft	Width of the East-West oriented access road that divides the array into top and bottom sections.	—
15	GCR (%)	Text Field	%	Ground Coverage Ratio — the ratio of module area to ground area. Higher GCR means denser packing. Linked to Row Spacing.	Table
16	Row Spacing	Text Field	m / ft	Distance between tracker rows (pitch). Automatically calculated from GCR and collector width, or can be manually entered.	Table
17	Azimuth	Text Field	degrees	The 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
18	Racking Angle	Slider	degrees	The 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
19	Create	Button	—	Places the custom array on the map at a location you specify. After clicking, you can position the array block on the map canvas.	—
20	Cancel	Button	—	Cancels the current array configuration without saving changes.	—
21	Close	Button	—	Closes the Custom Array Editor dialog and returns to the map interface.	—
22	Exclude partial arrays	Checkbox	—	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.	—
23	Update DC Capacity	Button	—	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
24	Array Builder / Array Editor Tabs	Tab 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.	—
