How it works
A simple path from idea to a fully specced, orderable solar system.
Tell us what to power
A guided chat asks which Western Harmonics product you want to run and how you plan to use it.
Size it to your sun
Share your location and we pull live solar data to size storage and panels for year-round performance.

We generate a single-line diagram, a full parts list, and a running total you can revise with us.
