Proposal Drawings
Sales-ready layouts and yield estimates that close deals without over-promising.
Proposal Drawings
A proposal drawing has two jobs that pull against each other: it has to look good enough to sign, and it has to be accurate enough that the design team can build on it rather than start again. Optimistic proposals win deals and then lose margin at engineering stage.
We produce proposal packages from whatever your sales team captured — a roof photo set, satellite imagery, a drone flight, a site survey form, or an existing utility bill. Roof planes are measured, obstructions and vents are placed, azimuth and pitch are established, and shading is modelled properly rather than eyeballed. The module count that comes out of that process is one your engineers can hold to.
Turnaround is the point of this service. Standard residential proposals come back within twenty-four hours, and a same-day lane is available for opportunities that need it.
