Built on code and permitting data you would otherwise look up by hand
The platform
Design, electrical, engineering, proposal and permit read from the same project — change the roof and everything downstream knows.
Outline the house on satellite or Nearmap aerial imagery, then build the roof from sections — five-point Gable and Hip, Shed, or a custom outline. The solver joins them into one building, valleys included, and Auto Fill lays out the modules.
Answer what is on site, one question at a time. Strings are assigned to inverter and battery inputs, the service is mapped, and NEC 705 interconnection checks run before anything is drawn.
Single-line diagram, conductor schedule, structural calculations, bill of materials and the permit plan set are generated from the same design, so they agree with each other. Plan sets go through professional review before release.
Production estimates from NREL PVWatts, proposals with e-signature, and a portal where homeowners follow their project from request to install.
The crew's measurements — main breaker, busbar, meter — arrive in System Config as survey facts. Fill the empty fields in one click; your own values are never overwritten.
Contractors see and claim leads only after their license and insurance are verified and they hold a qualification for the lead's state.
Preset roles from Owner to Installer, or your own: view, create, edit and delete set per area, and projects scoped to the people assigned.
How it works
Each step hands the next one its data, so nothing is typed twice.
Start a project from an address. Upload a bill and AI reads the usage and rate, flagging anything that does not add up, to size the system.
Trace the outline, build the sections, and Auto Fill the modules. System size updates as you go.
System Config walks the electrical: service, strings, batteries. Then the SLD, conductor schedule, BOM and structural calcs.
Send a proposal to e-sign, assemble the plan set for professional review, and keep the homeowner updated in their portal.
AI with guardrails
SolarPro automates the busywork and keeps the judgment calls with you.
AI reads the utility bill and checks itself: monthly usage that does not add up to the annual total, or a rate outside a plausible range, is flagged instead of guessed.
Inputs keep where they came from — installer, site survey, or a default — so a reviewer can see why a number is what it is.
Geometry suggested from imagery is for review, never final. Plan sets need professional review in SolarPro before they are released.
