Solar Design Services in New Hampshire

Proposal design for the sales stage, permit plan sets for New Hampshire authorities, 3D pre-design and shade studies, detailed engineering for rooftop and ground mount, civil and structural engineering with STAAD Pro verification, and yield and technical reports. Most New Hampshire installers start with one service and expand once turnaround and quality are proven.

Yes, and it is the substance of the work rather than a claim. New Hampshire adopts a state building code, but enforcement is a local decision and many smaller towns have no building inspector. Snow load is the dominant structural factor and reaches very high values in the White Mountains, and the state has a net metering cap that constrains larger projects.

Eversource New Hampshire, Liberty Utilities, Unitil, New Hampshire Electric Cooperative. Each expects its own diagram format and documentation, and export rules differ between them, which changes both the sizing case and what the drawings must show.

New Hampshire has modest installed capacity with high retail electricity rates, which supports the economics. The net metering system size cap constrains larger projects, and group net metering provides a route for shared arrangements. The engineering is snow-dominated, with the White Mountains carrying very high loads and extreme wind exposure at elevation. A substantial share of towns have no building inspector, so local review is inconsistent across the state.

Yes. Commercial and industrial work brings structural calculations, equipment coordination and interconnection complexity. Our largest documented project is an 11 MW DC rooftop installation on tin shed structures, which required structural verification across dozens of shed roofs alongside the electrical design.

A second engineer reviews every set against a jurisdiction specific checklist before it leaves us. The reviewer is not the person who drew it, because the fastest way to miss a setback error is to check your own work. Structural output is verified in STAAD Pro rather than assumed from a racking table.

You do. Work is covered by NDA and all intellectual property in the deliverables transfers to you. We do not reuse your drawings, your customer data or your templates for anyone else.

Yes. No retainer, no minimum volume, no onboarding fee. Most clients send one project, check the output, then scale.

Wind: moderate in the south, with genuinely extreme exposure at elevation in the White Mountains. Snow: a primary design driver, substantial in the south and very high in the White Mountains and northern counties. Seismic: low across New Hampshire. Also governing: ice loading and prolonged snow cover affect attachment detail, and extreme cold raises string open circuit voltage. These decide the racking selection and attachment schedule, so we verify them per site rather than applying a regional default.

New Hampshire State Building Code adopted statewide, with local enforcement being a municipal decision. Many smaller towns with no building inspector and therefore no local review. Net metering with a system size cap for full compensation, plus group net metering provisions. Very high snow load provisions in the White Mountains and northern counties. We work from these rather than a national template, because each can produce a review comment on an otherwise sound design.

City of Manchester Planning and Community Development (Manchester): largest city in the state with an established review process and Eversource interconnection. City of Nashua Building Department (Nashua): southern New Hampshire, the highest residential volume area in the state. City of Concord (Concord): capital city with an established process and moderate snow loading relative to the north. Towns without building inspectors (A substantial share of rural New Hampshire): enforcement is a municipal decision, so many smaller towns have no local building review at all. White Mountain region towns (Northern and mountain communities): very high ground snow loads and extreme wind exposure at elevation, in a completely different regime from the south.

No. The state building code is adopted statewide but enforcement is a municipal decision, and many smaller towns have no building inspector. In those towns there is no local plan review. The engineering obligation remains, and correct design matters more because nothing external will catch a mistake.

A provision allowing the output of a system to be allocated across multiple accounts rather than serving only the host meter. It provides a route for shared arrangements and for customers whose own roof is unsuitable. It has its own documentation requirements alongside the standard interconnection.
