Roof & Solar Measurement
Turn an address into a roof — and a roof into a solar proposal
What it is
A measurement tool that takes a street address and returns roof geometry, pitch, azimuth, shade analysis, and solar-yield estimates. It runs on Google's Solar API (Building Insights and Data Layers) and renders results in the brand's design system. Contractors go from 'we'd need to measure' to a shareable proposal on the same call.
- An address-to-roof pipeline using Google's Solar API to fetch building geometry, panel segments, and shade-corrected yield.
- A visualization layer that overlays the roof polygon, proposed panel layout, and annual kWh on an aerial tile.
- An export that produces a branded PDF or link a contractor can send to a prospect.
Capabilities
Roof geometry
Polygon outline, area, segment pitches and azimuths — all from an address lookup.
Solar yield modeling
Annual kWh, panel count, and capacity factors using Google's shade analysis on the specific roof.
Panel layout preview
A proposed array visualized on the actual roof; a contractor can adjust panel count and re-run.
Branded report
Output rendered in the partner's brandkit tokens — logo, typography, colors consistent with the rest of their kit.
Metal-roof-aware
Panel layouts understand Drexel's profiles and ridge/eave clearances; outputs match what the roofer will actually install.
Stored runs
Every measurement is a shareable link — no state in the contractor's browser; same URL reproduces the same report.
Architecture notes
- Google Solar API Building Insights for geometry and yield. Data Layers for the aerial and shade tiles.
- Address input is validated against Google's Places API before any Solar call is made.
- Reports are pure HTML + SVG overlays; no client-side map SDK required for viewing shared links.
- Coverage: United States at launch; expansion follows Google's data availability.
What each persona gets
Walk into a meeting with a real estimate instead of promising to measure later.
Quote during the first call. Close before the competitor has stopped quoting.
Every solar inquiry is a data point on product fit; the DAM learns which profiles win in which geographies.
Where it shows up
- Embedded on the contractor's WordPress site as a 'Get your solar estimate' block.
- Embedded in the portal's solar tab; reps generate reports while talking to a prospect.
- Callable as an agent tool — an AI assistant can request a solar estimate on behalf of a homeowner.
