What Rayn does

Every page. Every calc.
Every time.

Rayn handles the full planset stack — electrical, structural, labeling, and BOM — so your designers focus on jobs, not paperwork.

Electrical single & three-line

Auto-generated diagrams with correct wire sizing, conduit fill, NEC labels, and topology — for PV-only and battery systems.

Structural & racking calcs

Span tables, attachment spacing, load calcs, and side-view drawings — derived from your system config automatically.

BOM & permit package

Full bill of materials, NEC warning labels, placard, and cover sheet — bundled into a single stamped PDF ready to submit.

AHJ-aware rules engine

Jurisdiction-specific requirements baked in. Lehi rooftop EGC floors, DC raceway rules, utility-specific interconnection — handled.

Built-in validation

Design rule checks catch errors before they reach the AHJ. Flagged warnings for edge cases, not silent wrong outputs.

Battery system support

Tesla Powerwall 3, Enphase, whole-home and partial backup topologies — full three-line rendering with correct SID architecture.

Who it's for

Built for volume.
Trusted by experts.

Whether you're running a 450-person design firm or pulling your own permits, Rayn scales to your operation.

Design firms
10x your output without 10x the headcount

Your designers are doing 2–4 plansets a day. Rayn gets them to 10+. Same team, same quality bar, dramatically more throughput.

EPC contractors
Own your design process end to end

Stop outsourcing plansets and waiting on turnaround. Rayn puts permit-ready packages in your hands the same day the survey comes in.

Small installers
Professional plansets without a design team

Solo ops and small crews get the same AHJ-compliant output as the big players — at a price that makes sense for your volume.
