Solar Design Services in Vermont

Proposal design for the sales stage, permit plan sets for Vermont 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 Vermont 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. Vermont is procedurally unlike any other state. Solar installations require a Certificate of Public Good from the Public Utility Commission, with a streamlined registration route for smaller systems, and that state process rather than municipal zoning is the governing approval. Local permitting plays a much smaller role here than anywhere else in the country.

Green Mountain Power, Vermont Electric Cooperative, Burlington Electric Department, Municipal utilities. 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.

Vermont has high solar penetration relative to its population, supported by a net metering framework with siting and capacity adjustors. The defining feature for anyone working here is procedural: solar requires a Certificate of Public Good from the Public Utility Commission, with a streamlined registration route for smaller systems, and that state process rather than municipal zoning governs. It is a genuinely different approval model, and it catches installers expanding in from neighbouring states.

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 valleys, with ridge exposure raising values considerably in the Green Mountains. Snow: the dominant design driver and very high statewide, reaching extreme values at elevation. Seismic: low across Vermont. Also governing: ice loading and prolonged deep snow cover affect attachment and flashing detail, and extreme cold raises string open circuit voltage substantially. These decide the racking selection and attachment schedule, so we verify them per site rather than applying a regional default.

Certificate of Public Good required from the Public Utility Commission, with registration for smaller systems. State-level process taking precedence over municipal zoning for solar installations. Net metering with capacity and siting adjustors affecting compensation. Very high ground snow load provisions statewide. We work from these rather than a national template, because each can produce a review comment on an otherwise sound design.

Vermont Public Utility Commission (Statewide, the governing approval for solar): the defining feature of Vermont solar. A Certificate of Public Good or registration is required from the Commission, and this state process rather than municipal zoning governs. City of Burlington Department of Permitting and Inspections (Burlington): largest city, with municipal utility coordination and an established process alongside the state requirement. City of Rutland (Rutland): central Vermont with very high snow loading and an established review process. City of South Burlington (South Burlington): highest suburban residential volume in the state. Town offices (Small towns statewide): local involvement is limited compared with other states because the Public Utility Commission process governs, though towns receive notice and may participate.

It is the approval issued by the Vermont Public Utility Commission that solar installations require, with a streamlined registration route for smaller systems. It is the governing approval for solar in Vermont, taking precedence over municipal zoning. Installers arriving from other states often expect the town permit to be the main process and are surprised to find it is not.

Towns receive notice and may participate in the Commission process, and there can still be local requirements around construction. But the governing approval sits at state level rather than with municipal zoning, which is the reverse of the arrangement in almost every other state.
