Ground-Mount Design 101
HelioScope is commonly used for ground-mount array design. For those users who are new to designing ground mount systems, this document provides typical ground mount design principles:
Figure 1: Typical Ground Mount Design
Frames (often called “tables”) are an important element of ground-mount arrays. To create a ground-mount design, users should set their modules “up” to the desired depth of the bank (seen below as 4 up), and the width according to the length of the table (seen below as 10 wide).
Figure 2: Frame Sizes in HelioScope
Users often want to design Ground Mount arrays centered on an access path. With HelioScope’s Alignment function at the bottom of each field segment, this can be accomplished by splitting ground mounts into two field segments, one left-aligned and one right-aligned, to achieve the desired walkway-adjusted effect.

Tracker Layout Workaround
While HelioScope does not support trackers, there are ways to create the layout for trackers without the energy simulation with the following Field Segment settings:
- Azimuth 270
- Tilt: 0
- Frame Size 1 up x 60 wide
- Orientation: Portrait
- Row Spacing: ~10-15 ft. (depending on target GCR)
