Solar Installation Requirements in Tennessee
Tennessee solar installation: no solar installer credential exists (assembled absence, confidence reported) — the work is electrical and building at once. At $25,000 or more it is the contractor's licence with the CE electrical family (trade exam on CE-B buildings) and the S-specialty 'Solar Panel Installation' code on the building side; below the line the Limited Licensed Electrician answers in Fire Prevention localities; DC wiring, permits and interconnection run through the local electrical inspector, because Tennessee has no electrical board at all. Every claim sourced.
01 The requirements, sourced
- Contractor's licence required before bidding on any project of $25,000 or more — A contractor's licence must be in hand BEFORE contracting — 'including bidding, offering to engage, or negotiating a price' — for any project of $25,000 or more when acting as a prime contractor, certain subcontractor, or construction manager/consultant (Board page verbatim; § 62-6-103). The threshold counts the total project cost including materials, equipment and labor. An owner who contracts directly is a 'prime contractor' by statute (§ 62-6-102); the Board may allow an exception only up to 10% of the monetary limit (§ 62-6-103(a)(1)). S-TN-BLC-CONTRACTOR
- No standalone solar installer licence exists (verified absence) — Tennessee issues no solar-specific credential. Solar installation is the NO-EXAM specialty classification S-Solar Panel Installation on the same contractor licence (≥ $25,000 or whenever contracting at the threshold), with the electrical work carried by CE — or LLE below $25,000 in localities using the Division of Fire Prevention. Utility interconnection and local permitting sit outside the Board's reach. S-TN-BLC-OUTLINE
- Limited Licensed Electrician for electrical work under $25,000 — only in Fire Prevention localities — 'The Limited Licensed Electrician (LLE) license is only required by electricians performing work in a municipality utilizing the Division of Fire Prevention for permits or inspections and covers work less than $25,000 per project. Always first check with your local government … The LLE license is issued to individuals passing the LLE trade exam' (licence page verbatim). Statutory hooks: § 62-6-102(d) (definition), § 68-102-150 (registration with the state fire marshal). § 62-6-130: an LLE 'is not a contractor'. Initial fee $50; exam via Prov. S-TN-BLC-LLE
- No statewide electrical board exists (verified absence) — Tennessee has NO electrical commission or board. Electrical work is regulated through the SAME Board for Licensing Contractors via two classifications — CE (electrical contracting, ≥ $25,000, trade exam for the full and building/transmission/substation/alarm>70V/roadway/meter classes) and LLE (individual, < $25,000, only in localities using the Division of Fire Prevention) — plus whatever licensing the local electrical inspection authority imposes below and above the line. S-TN-TDCI-BOARDS
- Below $25,000 — and for every municipal rate — the local building department is the authority — Sub-threshold work, building permits, local electrical/plumbing/mechanical licensing and inspection fees are governed by city/county codes departments. Three official surfaces fix the boundary: the Board's guidance to 'Always first check with your local government' on the LLE and LLP pages; § 62-6-406 preserving 'Municipal and county licenses' for plumbing; and the nine-county adoption structure of the Home Improvement law (§ 62-6-501 et seq.). No municipal code or fee schedule was opened, so every city/county fact stays LOCAL_AUTHORITY_REQUIRED (research §O/§P). S-TN-BLC-LLE
