I built this because I was the bottleneck.
I’m a Florida PE. I built SDL because the tools I had were introducing errors.
Even a simple residential project pulls from too many sources: AutoCAD for geometry, Excel for wind loads, NEC tables for conductor sizing, ASCE for structural, the AHJ for local code quirks. None of them talk to each other. Every handoff is a place a number can be transcribed wrong, a reference can go stale, a rule can be missed.
So I built one interface that holds all of it. Every Florida AHJ, every NEC rule, every ASCE wind load, in the same engine, applied automatically, checked live as the design takes shape. The platform is the tool I built to stop catching my own mistakes.
If I wouldn’t sign it, it doesn’t ship.
Stamped under company E&O ($3M)

Built for solar, not adapted from CAD
The most thorough SLD engine in solar.
Most planset tools are missing pieces. Some skip structural, some skip electrical, some leave the AHJ rules to you.
We ship the complete packet in one engine. Structural, electrical, roof layout, AHJ rules per county.
The same engine I use to stamp Florida residential every day.
Wire sizes, OCPDs, ground paths derive live from the design. The design check engine catches what’s missing before the AHJ does.
Any topology
Microinverter + string + battery + supply-side tap, on the same canvas, in minutes.
Live electrical correctness
Wire sizing, OCPD propagation, ground inclusion, voltage drop. All derived from the design itself, not hand-entered.
No template lock-in
Built it once, fits every project. New equipment shows up in the database and starts connecting to everything else the next day.
Complete engineering package
Everything an AHJ asks for. Every time.
- PE-stamped structural letters
- Wind & snow load analysis
- Fault current calcs
- Voltage drop & conductor sizing
- Single-line diagrams (SLD)
- Equipment list / BOM
- Cover sheet, site plan, electrical, structural sheets
- AHJ-specific labeling & signage
The engineering calculators the platform runs on.
Wind load · Fault current · Voltage drop · Conductor sizing · String sizing.
A real PE on every project. In one workspace.
Not a ticketing system. Not an email thread. Not a portal that emails you to log into another portal. Your PE answers in the same hour.
Dedicated PE · In-app messaging · Live status · All revisions in one thread. Included at every tier.

AHJ needs a clear fire pathway on the street/driveway side of the roof. Can you add one to the front?

Approved. Stamping now.
AHJ rejects? We engineer it for you, free.
Rejection rate under 10%. If one happens, we take it from there at no cost. Re-engineer, re-stamp same day. No invoice. No fight.
FAQ
The questions every installer asks.
Do I have to drop my current engineer?
No. Most of our customers didn't. They kept their PE for commercial and complex work, and added us for the routine residential clogging their pipeline. Run one planset through, compare, and decide.
Is the first planset really free?
Yes. First planset stamped, no charge, no credit card. We can do that because most of what makes solar engineering expensive is overhead, not the engineering. We removed the overhead.
What if I hate it?
Cancel. Full refund within 30 days, no questions. We don't do contracts.
Can I get plans stamped without designing in the platform?
Yes. That's our full-service tier from $325. Higher price because our team designs it. Lower-cost tiers exist because the AHJ engine ran the checks while you were designing in the editor.
What about outside Florida?
Platform works nationally. Stamping outside Florida is quoted by state availability. The same-business-day SLA is Florida-only today. We're expanding state by state. Ask about yours.
Can I get on the phone with you?
Yes. Twenty minutes, your real project, no pitch deck. The slot you book is on my calendar.
Try one. Either it beats what you have or it doesn’t.
We don’t invoice the first planset.
By request. We respond within one business day.
