Questions homeowners ask
Does a solar classification cover roof mounting and wiring?
LLR’s FAQ separates panel work, roof mounting, wiring and structural upgrades. A solar label alone does not demonstrate authority for every task. Match each actual activity to the responsible practitioner’s current classification.

Which roof-mounting roles does LLR identify?
The FAQ names a licensed Residential Builder, a registered specialty contractor with Roofer classification, or a general contractor with General Roofing or Specialty Roofing authority. Ask LLR to resolve your actual arrangement.

Who performs the electrical and structural work?
LLR identifies separate authorized roles for wiring and connections and for required roof structural upgrades. Request the named electrical and structural practitioners and their actual credentials; do not treat a panel registration as the complete answer.

Is a firm certificate a standalone trade license?
No. LLR says a COA is not standalone and requires a resident licensee in responsible charge for each relevant office. Its page describes individual-practice and majority-owner/sole-resident-licensee exceptions. Confirm the exact entity and exception with LLR.

What project-cost basis appears in the specialty bond guidance?
The applications page says a $5,000 surety bond must be submitted when total project cost exceeds $5,000, combining labor and materials regardless of who buys materials. Verify applicability and current filing with the Commission.

Does the state credential settle local business requirements?
The Energy Office says local cities, towns or counties may also require a business license. Check the actual jurisdiction and keep this separate from state trade credentials and project approvals.

Your decision checklist
- Name the contracting firm and actual practitioners.
- Separate panel assembly, roof mounting, wiring and structural changes.
- Verify current classifications against each task.
- Resolve the firm COA or exact exception basis.
- Confirm applicable bond records and cost scope.
- Track local business, permits and utility steps separately.

Match the full work package to actual roles
| Task | Evidence to request |
|---|---|
| Contracting identity | Firm, practitioner and current registry record |
| Roof scope | Mounting method and responsible roofing authority |
| Electrical scope | Wiring and connection practitioner and classification |
| Structural changes | Required upgrade scope and authorized role |
| Firm and bond | COA or exception basis, applicable bond and follow-up |
Example: a proposal shows a solar registration but does not identify the roof-mounting or wiring team. The homeowner requests a task map and checks each named role with the responsible board. They keep the unresolved scope visible rather than assuming one credential authorizes the entire project.
Example: the design later adds roof reinforcement. The homeowner asks the contractor to identify the revised scope, responsible practitioner and updated records before treating the earlier review as complete. A change order explains the agreement; it does not itself establish trade authority.
Pros: a task map makes gaps and handoffs easier to identify before work. Cons: collecting records takes coordination, and current credentials do not establish workmanship, engineering adequacy or an outcome guarantee. Keep contract quality and actual inspection results in the review as well.
Reviewed October 6, 2026 against four primary agency resources cited beside the answers. The Energy Office summarizes pathways while LLR supplies the detailed role guidance; use the responsible licensing board to resolve any wording or scope question. No individual credential, entity exception, bond, design or project approval has been verified here.
Before offering residential installations in South Carolina, map the full package to actual roles, verify each practitioner’s current authority and resolve the firm’s authorization and applicable filing obligations. Establish the sales-to-installation handoff before relying on an application or a generic solar label. Business, contract, safety, local approval and utility obligations still need separate review; this page is a selected credential workflow.
Continue with installer selection, permits and utility milestones and Dominion SC bill records where applicable. Solar Survey AI’s evidence methodology and an agreed survey scope can support documented inputs; confirm availability, qualifications and conflicts. A survey does not grant a license or certify an entity exception. Homeowner monitoring connections and planned remote diagnosis remain coming soon.
