Trace the roof, lay panels to scale, set fire clearances and wire up strings with Voc checks — on any consumer drone. No LIDAR, no imagery subscriptions.

One top-down photo of the roof with any drone — even a sub-$300 DJI Mini.
We read altitude & lens from the metadata and compute the real-world scale automatically.
Trace facets, paint panels to scale, set access clearances. Areas and counts update live.
Group panels into series strings with Voc checks, then copy the results for your quote.
Auto-scale from drone metadata, or calibrate off any known object. Facet areas with per-edge lengths.
Click, or paint a whole row in one drag. Snap into tidy arrays, rotate to the roof angle.
Inset keep-out margins for maintenance & fire setbacks — panels that intrude turn red.
Build series strings and validate temperature-corrected Voc against your inverter (NEC 690.7).
Every roof, layout and string is saved to your account — revisit, edit and duplicate anytime.
No expensive imagery subscriptions or LIDAR. A consumer drone and a browser is all you need.
