The task
Designing a rooftop solar plant went through a chain of tools: tracing in CAD, calculations in Excel, a proposal in Word — and every recalculation started over. Engineers needed one workspace per project.
What we did
We built a web platform with a CAD canvas in the browser: the engineer clicks a building on the map, the system detects roof faces, lays out modules, calculates structural loads, yield, and economics, and generates the proposal, drawing, and report. A project lives in variants, and the client opens the result with a 3D model via a link.
