Code-compliant AHJ-ready solar permit drawings engineered specifically for Indiana's adopted electrical code — NEC 2017 — and formatted to satisfy every Indiana AHJ's submittal requirements from Indianapolis to every county.
Indiana uses NEC 2017. Duke Energy Indiana, IPL, and AEP Indiana each have specific solar permit drawing requirements. Indiana's REMC co-ops across the state each administer their own interconnection requirements for solar permit plan sets.
Indiana has adopted NEC 2017 & Indiana Building Code for residential solar PV systems. All solar permit drawings submitted to Indiana AHJs must comply with this edition — not earlier or later NEC versions.
NEC Article 690 governs all solar PV system wiring and component requirements. Indiana solar permit drawings must document compliance with every applicable section:
Indiana AHJs including Indianapolis Building Services and Marion County Permits apply code requirements and local amendments beyond base NEC. Our team knows every Indiana AHJ's specific expectations.
Every Indiana solar permit plan set is a complete, NEC 2017-compliant package. Each sheet is engineered to satisfy both AHJ review and utility interconnection requirements.
The cover sheet documents the project scope, applicable codes (NEC 2017), designer credentials, and all project identification data required by Indiana AHJs.
The site plan provides an overhead aerial view with property setbacks, utility meter location, Indiana fire code access pathways (required by Indianapolis Building Services and all Indiana fire departments), and panel-to-inverter routing.
The single-line diagram is the primary solar engineering drawing — a complete electrical schematic from PV source circuits through inverter to utility interconnection. Fully compliant with NEC 2017 Article 690.
The three-line diagram provides per-phase detail with conductor sizing and OCPD ratings — required by Indianapolis Building Services and many Indiana AHJs for battery systems and larger arrays.
NEC 690.12 rapid shutdown compliance documentation — the system type, component locations, and all required labels. This is the most common item flagged in Indiana AHJ corrections when missing or incomplete.
All NEC-required warning labels, AC/DC disconnect labels, rapid shutdown placards, and code signage are included and positioned for your specific Indiana installation.
Beyond AHJ submission, Indiana solar projects require utility interconnection documentation. Our plan sets include drawings formatted for Indiana Michigan Power (AEP) and Duke Energy Indiana — both with distinct Indiana interconnection requirements.
Equipment datasheets for all components — modules, inverter, optimizers, racking, and storage — are included and formatted to each Indiana utility's specifications.
Understanding the difference between statewide NEC 2017 requirements and local Indiana AHJ requirements is critical to first-pass approval.
As one of Indiana's highest-volume solar permit AHJs, Indianapolis Building Services processes a significant number of residential solar permit applications. Our plan sets are built to their specific portal format, sheet naming, and documentation requirements.
Marion County Permits and Hamilton County Building are key Indiana solar markets with their own specific documentation requirements. Our team has prepared plan sets for both jurisdictions — we know what their reviewers look for.
