Direct Answer
To find a solar installer familiar with Florida’s specific codes, start by verifying the contractor’s Florida license, reviewing their experience with solar photovoltaic (PV) installations in Florida, and asking how they handle building permits, electrical requirements, wind-uplift resistance, roof loading, and local building department approvals. For commercial properties, choose an installer who understands how solar equipment interacts with the existing roof system, drainage, waterproofing, and manufacturer warranties.
Florida has specific building and electrical requirements that affect solar installations. The Florida Building Commission identifies December 31, 2026, as the effective date for the 9th Edition (2026) Florida Building Code. As of October 2026, the 8th Edition (2023) remains the current edition before that transition. Ask the installer which code edition and local amendments apply to your project’s permit date and jurisdiction. Review the official Florida Building Code development resources before approving the design.
For commercial buildings, the safest approach is to select an installer who can coordinate the solar system with the building owner, roofing contractor, electrical professionals, structural engineer when required, utility provider, and local building department.
Who This Applies To
- Commercial property owners considering rooftop solar
- Condo and HOA boards evaluating solar installations
- Facility managers and property managers
- Commercial real estate developers
- Industrial and warehouse property owners
- Building owners concerned about roof warranties and insurance
- Owners planning solar installations on existing commercial roofs
Not for: This guide does not replace project-specific legal, electrical, structural, engineering, or code-compliance advice. Requirements depend on the building, solar system, project location, permit date, and applicable local rules.
1. Verify the Installer’s Florida License
Start by checking whether the installer holds an appropriate Florida contractor license for the work being proposed.
Florida’s Department of Business and Professional Regulation (DBPR) provides official licensing resources for certified and registered solar contractors. Florida’s electrical contractor licensing authority also confirms that a license is required to install photovoltaic systems and that certified or registered electrical contractors may install solar electric systems within their licensed scope.
Use these official resources:
- Florida certified solar contractor licensing portal
- Florida registered solar contractor licensing portal
- Florida electrical contractor licensing FAQs
- Florida contractor license verification guidance
Ask for the contractor’s license number and verify that the license is active and appropriate for the proposed scope. Also confirm that the business performing the work is properly qualified under the license.
2. Look for Florida-Specific Solar Experience
A contractor who has installed solar panels in another state may not have sufficient experience with Florida’s permitting requirements, wind exposure, local amendments, and storm-related design considerations.
Ask potential installers:
- How many solar installations have you completed in Florida?
- Have you worked in this county or municipality?
- Have you completed projects in Florida’s High-Velocity Hurricane Zone (HVHZ), where applicable?
- Can you provide examples of projects with similar roof types?
- Who prepares the permit drawings and engineering documents?
- Who coordinates inspections and utility interconnection?
Prioritize contractors who can explain the local approval process clearly rather than simply claiming to be familiar with Florida codes.
3. Confirm Which Florida Building Code Edition Applies
Florida updates its building code periodically. The applicable edition can depend on the permit application date, the effective date of a code update, and the local authority’s requirements.
The Florida Building Commission identifies December 31, 2026, as the effective date for the 9th Edition (2026) Florida Building Code. Therefore, projects being planned during the transition should confirm which edition applies before finalizing drawings or submitting a permit application.
Ask the installer:
- Which Florida Building Code edition will govern this project?
- Have you checked local amendments and permitting requirements?
- Who confirms the applicable electrical code requirements?
- Will the permit documents identify the applicable design criteria?
- How will code changes affect a project that crosses the effective date?
Review the official Florida Building Code resources and the relevant local building department’s requirements.
4. Ask How the Solar System Will Resist Florida Winds
Wind resistance is a critical consideration for rooftop solar in Florida. The mounting system, attachment method, roof construction, building location, and applicable design criteria all affect the engineering requirements.
Ask the installer to explain:
- How wind loads will be determined
- How the solar mounting system will be attached or ballasted
- Whether structural calculations are required
- How the design accounts for applicable wind exposure and roof-edge conditions
- How the system’s installation instructions and product approvals will be verified
- Whether the project requires signed and sealed engineering documents
Do not accept a generic statement that the panels are hurricane-rated as proof that the complete installation meets the project’s requirements. The mounting system and its connection to the building must be evaluated for the specific project.
5. Verify Structural Capacity Before Installation
Solar panels, mounting equipment, ballast, and associated components add loads to a roof. The building’s structural capacity should be evaluated when required by the project’s conditions and applicable code.
For an existing commercial building, ask:
- Will the existing roof structure support the proposed system?
- Is a structural evaluation required?
- Will the installation introduce concentrated loads?
- Will ballast or attachments affect the roof assembly?
- Are there existing rooftop HVAC units or other equipment that affect the layout?
- Will future equipment access and roof maintenance remain practical?
Where structural analysis is required, obtain the appropriate evaluation from a qualified professional rather than relying solely on the solar installer’s visual assessment.
6. Assess the Existing Roof Before Installing Solar
For commercial buildings, the roof should be evaluated before solar installation begins. A roof with leaks, deteriorated membranes, moisture-damaged insulation, or limited remaining useful life may need repairs or replacement before the solar system is installed.
Ask the installer and roofing professional to review:
- Roof age and remaining useful life
- Membrane condition
- Existing leaks and previous repairs
- Flashing and penetration details
- Drainage and ponding water
- Roof warranty requirements
- Future roof replacement access

7. Ask How the Installer Will Protect the Roof Warranty
Solar attachments and installation work can affect a roof’s watertightness and warranty coverage if they are not coordinated properly.
Ask:
- Will the existing roof manufacturer permit the proposed installation method?
- Will penetrations be made through the roof membrane?
- Who is responsible for flashing and waterproofing?
- Does the installation require approval from the roof manufacturer?
- Will a roofing contractor be involved in attachment and flashing work?
- Will the existing warranty remain valid after installation?
- Who is responsible if solar installation causes a roof leak?
Obtain written confirmation of warranty requirements before construction begins. Do not rely on verbal assurances that the existing roof warranty will remain unaffected.
8. Confirm Permits, Inspections, and Utility Approval
A qualified installer should explain the complete approval process before you sign the contract.
Depending on the project, the process may involve:
- Building permit applications
- Electrical permit requirements
- Structural drawings and calculations
- Product approval documentation where applicable
- Local building department inspections
- Electrical inspections
- Utility interconnection approval
- Permission to operate, where required by the utility
Ask the installer to identify which approvals are included in the contract and which are the property owner’s responsibility. Confirm requirements directly with the local building department and utility serving the property.
9. Look for Relevant Professional Credentials
Professional credentials can help demonstrate specialized training, but they should supplement—not replace—Florida licensing, relevant experience, and code-compliant project documentation.
For example, the U.S. Department of Energy recommends checking installer credentials, relevant experience, licensing, insurance, subcontractor qualifications, and warranty arrangements. It also identifies certifications from the North American Board of Certified Energy Practitioners (NABCEP) as a credential worth considering.
Read the Department of Energy’s guide: Decisions, Decisions: Choosing a Solar Installer.
For a commercial project, ask which individuals will handle system design, electrical work, structural coordination, and roof attachment details. Verify the qualifications required for each part of the work.
10. Compare at Least Three Detailed Proposals
Request written proposals from several qualified installers. Compare more than the total price.
| Item | What to Check |
|---|---|
| Licensing | Appropriate, active Florida license |
| Code compliance | Applicable code edition and local requirements identified |
| Engineering | Structural and wind-design responsibilities clearly stated |
| Permitting | Permit applications and inspections included or clearly excluded |
| Roof protection | Attachment, flashing, and waterproofing responsibilities defined |
| Equipment | Panels, inverters, mounting systems, and electrical components specified |
| Warranties | Equipment, workmanship, and roof warranty responsibilities explained |
| Subcontractors | Names, roles, and qualifications disclosed |
| Closeout | Inspection records, approved plans, warranties, and system documentation included |
Be cautious of unusually low bids that omit engineering, permits, roof repairs, waterproofing, or utility coordination.
11. Ask These Questions Before Signing
Use this checklist during your final contractor interviews:
- Can you provide your Florida contractor license number?
- Have you completed similar installations in this Florida jurisdiction?
- Which code edition and local amendments apply to my project?
- Who is responsible for wind-load calculations and structural review?
- Will the existing roof be assessed before installation?
- How will roof penetrations and flashing be handled?
- Will the existing roof warranty remain valid?
- Who will obtain permits and coordinate inspections?
- Who will arrange utility interconnection?
- Will you provide final inspection records and closeout documentation?
- What happens if the installation causes a roof leak?
- Can you provide references for similar completed Florida projects?
A reliable installer should answer these questions clearly and provide supporting documentation where appropriate.
12. Keep the Project Documentation
After selecting an installer, maintain a permanent project file containing:
- Contractor license verification
- Signed proposal and contract
- Approved permit documents
- Engineering calculations and drawings, where applicable
- Equipment and mounting-system specifications
- Roof assessment and repair records
- Inspection approvals
- Utility interconnection documentation
- Equipment and workmanship warranties
- Roof manufacturer correspondence
- Final system layout and closeout documents
These records can help with future roof repairs, warranty questions, insurance reviews, property transactions, and maintenance.
Bottom Line
To find a solar installer familiar with Florida’s codes, verify the contractor’s license, check experience in the relevant jurisdiction, confirm the applicable Florida Building Code edition, and ask for clear answers about wind resistance, structural capacity, permits, inspections, and utility approval.
For commercial rooftops, also coordinate the installation with a qualified roofing professional before work begins. Protecting the roof’s waterproofing, confirming structural suitability, and documenting warranty requirements can help prevent expensive problems after the solar system is installed.
