The problemWhat we were
What we were
asked to fix.
PV installers in DACH spend ~4 hours per proposal — sourcing roof maps, calculating orientation, picking a compatible BOM, drafting the cover letter. At 30 inquiries a week, that's a full-time engineer doing work no engineer wants to do.
How we shipped it
The build.
01
Polygon-on-map intake: the installer draws a service zone, the engine pulls solar insights for every building in scope.
02
Engineering pipeline picks compatible inverters, batteries and mounts from a 50+ component catalog under strict tier rules — zero spec errors by construction.
03
Generates one full PDF proposal per site — BOM, ROI, cover letter, branded — in seconds, ready for the installer to send.
