Code-compliant solar permit drawings engineered specifically for Wyoming's adopted electrical code — NEC 2020 — and formatted to satisfy every Wyoming AHJ's submittal requirements from Cheyenne to every county.
Wyoming adopts NEC 2020. Rocky Mountain Power and Black Hills Energy have specific solar permit drawing requirements. Wyoming's wind environment often requires additional structural documentation in solar permit plan sets for wind load compliance.
Wyoming has adopted NEC 2020 & Wyoming Building Codes for residential solar PV systems. All solar permit drawings submitted to Wyoming AHJs must comply with this edition — not earlier or later NEC versions.
NEC Article 690 governs all solar PV system wiring and component requirements. Wyoming solar permit drawings must document compliance with every applicable section:
Wyoming AHJs including Cheyenne Building Division and Casper Building Services apply code requirements and local amendments beyond base NEC. Our team knows every Wyoming AHJ's specific expectations.
Every Wyoming solar permit plan set is a complete, NEC 2020-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 2020), designer credentials, and all project identification data required by Wyoming AHJs.
The site plan provides an overhead aerial view with property setbacks, utility meter location, Wyoming fire code access pathways (required by Cheyenne Building Division and all Wyoming 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 2020 Article 690.
The three-line diagram provides per-phase detail with conductor sizing and OCPD ratings — required by Cheyenne Building Division and many Wyoming 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 Wyoming 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 Wyoming installation.
Beyond AHJ submission, Wyoming solar projects require utility interconnection documentation. Our plan sets include drawings formatted for Rocky Mountain Power (PacifiCorp) and Black Hills Energy Wyoming — both with distinct Wyoming interconnection requirements.
Equipment datasheets for all components — modules, inverter, optimizers, racking, and storage — are included and formatted to each Wyoming utility's specifications.
Understanding the difference between statewide NEC 2020 requirements and local Wyoming AHJ requirements is critical to first-pass approval.
As one of Wyoming's highest-volume solar permit AHJs, Cheyenne Building Division processes a significant number of residential solar permit applications. Our plan sets are built to their specific portal format, sheet naming, and documentation requirements.
Casper Building Services and Laramie County Permits are key Wyoming solar markets with their own specific documentation requirements. Our team has prepared plan sets for both jurisdictions — we know what their reviewers look for.
From plan set order to Permission to Operate — the complete Wyoming solar permitting process.
