Code-compliant outsourced solar permit drawings engineered specifically for New Hampshire's adopted electrical code — NEC 2017 — and formatted to satisfy every New Hampshire AHJ's submittal requirements from Manchester to every county.
New Hampshire uses NEC 2017 under the NH State Building Code. Eversource NH has specific solar permit drawing requirements under the NH Net Metering law. Snow load structural documentation is typically required in solar permit plan sets given New Hampshire's winter climate.
New Hampshire has adopted NEC 2017 & New Hampshire State Building Code for residential solar PV systems. All solar permit drawings submitted to New Hampshire AHJs must comply with this edition — not earlier or later NEC versions.
NEC Article 690 governs all solar PV system wiring and component requirements. New Hampshire solar permit drawings must document compliance with every applicable section:
New Hampshire AHJs including Manchester Building Dept and Nashua Building Division apply code requirements and local amendments beyond base NEC. Our team knows every New Hampshire AHJ's specific expectations.
Every New Hampshire 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 New Hampshire AHJs.
The site plan provides an overhead aerial view with property setbacks, utility meter location, New Hampshire fire code access pathways (required by Manchester Building Dept and all New Hampshire 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 Manchester Building Dept and many New Hampshire 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 New Hampshire 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 New Hampshire installation.
Beyond AHJ submission, New Hampshire solar projects require utility interconnection documentation. Our plan sets include drawings formatted for Eversource Energy New Hampshire and Liberty Utilities (Unitil) — both with distinct New Hampshire interconnection requirements.
Equipment datasheets for all components — modules, inverter, optimizers, racking, and storage — are included and formatted to each New Hampshire utility's specifications.
Understanding the difference between statewide NEC 2017 requirements and local New Hampshire AHJ requirements is critical to first-pass approval.
As one of New Hampshire's highest-volume solar permit AHJs, Manchester Building Dept processes a significant number of residential solar permit applications. Our plan sets are built to their specific portal format, sheet naming, and documentation requirements.
Nashua Building Division and Hillsborough County Permits are key New Hampshire solar markets with their own specific documentation requirements. Our team has prepared plan sets for both jurisdictions — we know what their reviewers look for.
