2Panel & layout
Pick a panel from the built-in datasheet library, or choose Manual to enter exact dimensions from your own datasheet. This drives the panel count, rows and columns.
Panel size (datasheet)—
Rows × columns (placed)—
Overall structure length (across columns)—
Overall structure width (front-to-back, all rows)—
Panel layout + structure — updates live as you edit panel count/columns (step 2) and girder quantities (step 3)

⌖Roof fit check — layout on your photo
Places the panel layout from step 2 on your site image at true size. Works best with a top-down Google Maps satellite screenshot of the roof.
Add a site image in step 1 to use this.
Scale not set — layout size is approximate
1) Tap Set scale, then tap both ends of something you know the length of (e.g. a roof edge) and enter that length. 2) Drag the blue layout into place and rotate it. Change columns/rows in step 2 to see if a different arrangement fits better.
