Solar Array Ground Bearing Earthing Package

Calculates source-bound PV rack and foundation metrics from a deterministic SSC-07 task-owned source pack. The template combines wind force, support reaction, bearing pressure, ballast uplift, grid resistance, and ground-potential-rise checks.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All source-pack values given for the SSC-07 solar array package
medium:
All source-pack values given for the SSC-07 solar array package
hard:
