New Hampshire solar installation: no solar-specific contractor credential exists (verified absence — the OPLC boards list has none); the electrical work is covered by the active NH electrician licence at the 30-volt threshold, the Electrical Corporation (RSA 319-C:10) is the business route, and roof-penetrating work on older structures can trigger the NHDES asbestos rules (certified inspector, licensed contractor, 10-working-day notifications). Every claim sourced and dated.
No statewide general-contractor license exists (verified absence) — The OPLC boards list (read 2026-10-05) contains no contractor, construction, general-contractor, home-improvement, roofing or remodeling board; the construction-relevant boards are the Electricians' Board, the Mechanical Licensing Board and the Home Inspectors board. No state-level general-contractor licence, registration or bond exists; building permits are issued by municipalities. S-NH-BOARDS-LIST

10-working-day notifications for major abatement and load-bearing demolition — NHDES verbatim: 'An Asbestos Abatement Notification Form must be submitted at least 10 working days prior to the start of any major asbestos abatement project. An Asbestos Demolition Notification Form must be submitted and received by NHDES at least 10 working days prior to the start of any demolition activity that would remove any load-bearing member of a structure. The Asbestos Demolition Notification Form is required even if the results of the inspection determine that the facility contains no ACM.' S-NH-DES-ASBESTOS
