Step 2 · Site, Equipment & Roof
Step 2 turns the imported design into a physical site configuration. The user reviews the Aurora layout, confirms PV and storage equipment, attests the site review, and fills in roof, framing, and mounting details for each roof face.
What trips people here: three things gate the rest of the design. (1) Site review must be attested — an un-attested layout reads as unreviewed downstream. (2) Per-face module counts must sum to the imported total — if Face 1 + Face 2 ≠ the Aurora layout, Step 3 and the BOM inherit the wrong count. (3) Mounting hardware (attachment + rail) must match the Step 1 racking system — a SnapNrack job with mismatched rails diverges from the BOM and the planset.
What To Check
- Aurora layout and roof faces match the intended design.
- Site review is attested when the design has been reviewed.
- Module, inverter, optimizer, combiner, and battery quantities match the project scope.
- Roof-face module counts match the imported layout.
- Roof material, deck type, sheathing, framing, spacing, max span, and face area are complete.
- Mounting hardware, attachment, and rail selections match the racking system selected in Step 1.
Important Controls
- Aurora CAD/layout viewer and roof-face selector.
- Site reviewed attestation.
- Align with financing pack.
- Change system architecture.
- PV System panel for modules, inverters, optimizers, and swap actions.
- Energy Storage panel for battery quantity and SKU changes.
- Combiners panel when the topology uses combiners.
- Roof & Attachments panel.
- Roofs & Faces editor.
- Copy roof/framing and copy mounting actions.

The electrical step depends on this physical model. Module count, inverter family, battery presence, roof faces, racking hardware, and equipment quantities drive the Step 3 graph, wire schedule calculations, BOM, and permit output data.
