Roof faces i
No faces yet. Draw each sloped section of your roof separately — a simple gable has two, a complex roof more.
Drag a face to move it, a corner to reshape. Delete/Backspace removes it. Use “Draw ridge” to slice a face into two planes along a roof line — repeat on each piece to build a hip or envelope roof. “Flip slope” reverses which way a plane points.
Lay out panels, then click one, and shift-click another to select the whole block between them (⌘/Ctrl-click toggles a single panel). Delete removes the selected panels. Drag to move; click the map or Esc to deselect; ⌘/Ctrl-Z undoes.

Changing size or setback re-lays the panels; wattage just rescales the system.

Obstructions apply to every face — the engine casts the sun over a full year to see what they block.
