Solar array

Asset reference

Concept

A solar array converts sunlight into electrical power. In ASTROLAB it is a child of a spacecraft (edited in the Power tab): area, efficiency, mount face, and optional sun-tracking drive determine generation when Power Analysis runs.

Arrays are not merely decorative meshes — Power Analysis selects which panels contribute, applies eclipse and incidence, and feeds batteries and loads.

Parameters (per panel)

Parameter Type Default / options
Asset ID text
Mount face select +X, −X, +Y, −Y, +Z, −Z
Pos X/Y/Z [m] decimal Offset on bus face
Euler sequence select 123, 132, 213, 231, 312, 321 (default 321)
R1/R2/R3 [°] decimal
Dim X/Y/Z [m] decimal Panel box
Use SADM (single-axis drive) checkbox off
Pointing select Fixed / Sun-Tracking (if SADM)
SADM axis X/Y/Z decimal default [0,1,0]
Area [m²] decimal 5
Efficiency decimal 0.3

Parent spacecraft also sets bus size (Custom Design X/Y/Z) or a default model.
