What a plan set is, and how we read it

A plan set is the drawing package for an install: the site plan, the single-line diagram and the equipment schedule. Upload one and we return every label the equipment on it requires.

What is in a plan set

• Site plan — the building, the array, where the equipment sits.
• Single-line diagram — how the system is wired, from module to service.
• Equipment schedule — makes and models of modules, inverters, batteries, meters.
• Often also: structural details, attachment calculations, the permit application.

Upload the whole PDF rather than one page. The labels are decided by equipment that is usually named only on the schedule, and the positions come off the site plan.

What we read

Modules, inverters, batteries and meters, with manufacturer and model where the drawing names them. From that we work out the configuration, and from the configuration the labels — grouped by where each one goes.

Why some drawings return less

A PDF exported from design software is text, and reading it is exact. A scan or a photograph of a drawing has to be read as an image, which is slower and less certain.

Three things reliably reduce what comes back:

• An equipment schedule that is an image rather than text.
• Equipment drawn but never named — a disconnect on the diagram with no label beside it.
• A drawing supplied as a photograph of a printed sheet.

Nothing is locked: anything missed can be added by hand on the results page.

What happens to the file

Whether we keep the PDF is your choice, in Settings. The setting applies to future uploads rather than to documents already held, and you can delete everything from the same page.
