Start typing — pick a suggestion, or click a rooftop on the map.

Satellite imagery

Esri World Imagery — most areas 2022–2025. Add a Google key below for a survey-grade, dated capture.

Roof detection (automatic)

Uses survey-grade roof data automatically where available — real roof planes, shading-aware production & imagery date — otherwise the OpenStreetMap footprint.

100% offset right-sizes the system to your usage.

Where available, roof planes & production come from Google's Solar API (survey-grade, shading-aware, dated imagery); otherwise planes are inferred from the OpenStreetMap footprint and production from regional averages. Panel counts, equipment & pricing are illustrative — confirm with a licensed installer.
