Permit Design builds New Hampshire solar permit plan sets for licensed solar installers, EPCs, and roofing companies statewide. Eversource Energy (formerly Public Service of New Hampshire, PSNH) is the primary electric utility serving most of New Hampshire including Manchester, Nashua, Concord, Dover, Portsmouth, and surrounding areas. Eversource NH offers full retail net metering under New Hampshire Public Utilities Commission oversight. NH Electric Cooperative serves rural and northern New Hampshire communities including the Lakes Region, White Mountains, and North Country.
New Hampshire solar plan sets require heavy New England cold climate snow loads — 40 to 60+ psf depending on location and elevation. The White Mountains and higher elevations of northern New Hampshire see the highest values. Granite State communities like Manchester and Nashua see approximately 40 psf while mountain communities can exceed 60 psf. NEC 2020 applies statewide under the NH State Building Code. New Hampshire offers net metering and participates in the New England regional renewable energy certificate market.
New Hampshire permitting is managed at the city and town level — municipalities handle their own building permits with no statewide solar-specific streamlining. Manchester and Nashua each have city building departments. Concord, Dover, Portsmouth, Keene, and Laconia each operate separate offices. New Hampshire towns — even small ones — have their own building officials. Eversource NH interconnection is submitted simultaneously with the building permit. NH Electric Cooperative interconnection is submitted to NHEC separately from the AHJ permit. New Hampshire heavy snow loads (40–60+ psf) are the single most important structural factor in NH plan sets — generic continental US templates are routinely rejected by New Hampshire building officials.
Eversource Energy Serves Most of NH With Full Retail Net Metering Under NH PUC Oversight. NH Electric Cooperative Serves Rural and Northern Areas Under the Same Net Metering Obligation.

New Hampshire Solar Permit Design — Installer FAQ
Eversource Energy (formerly Public Service of New Hampshire, PSNH) is the primary electric utility serving most of New Hampshire including Manchester, Nashua, Concord, Dover, Portsmouth, Keene, and Laconia. Eversource NH offers full retail net metering under NH PUC oversight. NH Electric Cooperative (NHEC) serves rural and northern New Hampshire — the Lakes Region, White Mountains, North Country, and surrounding areas. NHEC also offers solar net metering. A small portion of NH is served by Unitil Corporation. Each utility has its own interconnection application — confirm utility per address before building every NH plan set.
Yes. New Hampshire full retail net metering is required under RSA 362-A:9. Eversource NH and NH Electric Cooperative must offer net metering for qualifying residential and commercial solar systems under NH Public Utilities Commission oversight. Full retail 1:1 net metering means every kilowatt-hour exported to the grid earns a credit at the full retail electricity rate. Monthly excess credits roll forward to the following month's bill indefinitely. New Hampshire's RSA 362-A:9 net metering is among the most financially favorable frameworks in New England — stronger than states like Maine where net metering structure has been subject to more regulatory change. Confirm current program terms, system size limits, and specific interconnection requirements with the specific utility (Eversource NH or NHEC) per address before finalizing system design and customer financial projections.
New Hampshire full retail net metering (RSA 362-A:9) is the primary financial incentive. NH RSA 72:61 allows municipalities to adopt solar property tax exemptions — many NH towns have adopted exemptions varying in amount by municipality. New Hampshire participates in the New England RPS and SREC market, which can provide additional value for qualifying solar systems. New Hampshire has no broad-based income tax on wages, so no state solar income tax credit applies. Federal 25D residential credit expired December 31, 2025. Confirm municipal property tax exemption status with the local assessor per address.
NEC 2020 under the NH State Building Code, administered under the NH Code of Administrative Rules by the NH Division of Fire Safety. New Hampshire adopted NEC 2020 statewide for all electrical installations including solar PV systems. Article 690 governs NH solar PV system design — including rapid shutdown (Section 690.12), array wiring methods, inverter disconnect placement, and system labeling. Article 706 governs energy storage systems. Article 625 governs EV charging equipment. IBC 2021 and IRC 2021 are New Hampshire's current structural standards. NH's heavy snow loads (40–60+ psf) interact directly with IRC 2021 structural requirements — the combination must be handled correctly for NH AHJ approval. Article 690 governs NH solar PV system design including rapid shutdown requirements, array wiring, inverter disconnects, and system labeling. Article 706 governs energy storage systems. Article 625 governs EV charging equipment. IBC 2021 and IRC 2021 are NH's current structural standards. Some NH municipalities may maintain local amendments — confirm with the specific AHJ before finalizing plan set content.
Yes — New Hampshire has some of the heaviest snow loads in the continental United States outside Alaska. Southern NH (Manchester, Nashua) sees approximately 40 psf ground snow load. Central NH (Concord, Lakes Region) sees approximately 40-50 psf. The White Mountains and northern NH communities see 50 to 60+ psf at elevation. These values are significantly heavier than Midwest markets (Indiana 20-25 psf, Kentucky 15-20 psf) and require robust ASCE 7 cold climate structural calculations. We confirm ASCE 7 ground snow load per specific address for every NH plan set. Generic templates from other regions fail NH structural plan review.
New Hampshire has no statewide PE stamp requirement for standard residential rooftop solar installations. Eversource NH territory AHJs — Manchester, Nashua, Concord, Dover, Portsmouth — do not require a PE stamp for standard residential rooftop solar. Some NH municipalities in the White Mountains or with complex structural conditions may request PE-stamped drawings — confirm with the specific AHJ before ordering. Commercial solar installations require PE-stamped structural drawings. Ground-mount systems of all sizes require PE-stamped structural engineering. We coordinate PE stamp services for NH commercial and ground-mount projects upon request.
New Hampshire has full retail net metering (RSA 362-A:9), which is among the strongest net metering frameworks in New England. No state income tax on wages means no state solar income tax credit but also no complication from tax credit calculations. NH's RPS and SREC market participation adds value for qualifying systems. NH's heavy snow loads (40-60+ psf) mean plan set structural sections need to be built for New England conditions — solar installers coming from warmer markets frequently underestimate NH's structural requirements. Eversource NH and NHEC each have established solar interconnection processes that are well-documented under NH PUC oversight.
Most New Hampshire residential solar permit plan sets are delivered in 24 to 48 hours from project submission. Battery storage plan sets ship same day when ordered with the solar plan set. Standalone battery-only plan sets: 24 to 48 hours. Commercial solar plan sets: 3 to 5 business days depending on system complexity. EV charger permit plan sets: 24 to 48 hours. All NH residential plan sets include the Eversource NH or NHEC interconnection package per utility confirmed at address, RSA 362-A:9 net metering documentation, ASCE 7 heavy snow load calcs confirmed per specific NH location (40–60+ psf depending on address and elevation), NEC 2020 Article 690 single-line diagram, structural calculations, and all 7 plan set sheets.
