Solar permit plan sets in 5 minutes — with the NEC section printed next to every number
Solar Scripto is permit-design software for residential solar installers. Describe a solar + battery system in one sentence and get a permit-grade one-line (single-line) diagram, live NEC code checks across 81 code sections (690.7, 690.8, 705.12, 706 and more, 2017–2026 editions), a NEC 220.82 service load calculation, a scaled site plan, structural and production simulations, and a sealed 10-sheet permit-ready package — with a scan-to-verify Design Seal.
How the engine works. A language model does exactly one job: it reads your sentence and turns it into structured inputs, the same thing a designer does reading your email. It never touches a calculation. Conductor ampacity, temperature correction, conduit fill, busbar limits and OCPD sizing are all deterministic — same inputs, same numbers, every time. That is why every value on the sheet carries the NEC section it came from: you are not asked to trust it, you are asked to check it in about ten seconds.
Kickback Guarantee. If an AHJ red-lines a code issue our engine generated, we revise it free within 4 business hours and pay your resubmittal fee, up to $250 per set.
