11 Things to Know About a Solar Permit in Naples, FL

Key Takeaways

• Confirm jurisdiction by property address first: many Naples-addressed homes sit in unincorporated Collier County, which has different portals, checklists, and reviewers than the City of Naples.

• A solar permit is generally required before installing PV in the Naples area, including rooftop and ground-mounted systems; installing first risks stop-work orders and fines.

• Submit a dimensioned roof plan showing array layout, system size, wind-uplift zones, roof perimeter, and penetration-flashing details to avoid correction notices.

• Expect signed and sealed structural drawings and calculations covering uplift, lateral loads, and added dead load, which requires a Florida-licensed engineer.

• A Florida-registered electrical engineer must seal plans when system value exceeds $50,000 or service exceeds 600A residential or 800A commercial at 240V.

• Ground mounts in Collier County need a proposed site plan, possible certified survey above 400 sq ft of new impervious area, and 5-foot septic separation if applicable.

Going solar in Southwest Florida sounds like a dream: plenty of sunshine, lower power bills, and a little hurricane-season peace of mind if you add a battery. But before a single panel goes up, you need a solar permit in Naples, FL, and that is where plenty of good projects get stuck. Whether you are a solar installer juggling a dozen jobs, a general contractor adding PV to a build, a realtor helping a client, or a homeowner who just signed a proposal, the paperwork can feel like a maze.

Here is the good news: once you know which office controls your address and what reviewers actually want to see, the process gets a lot friendlier. In 2026, both the City of Naples and Collier County run online submittal portals, and both expect code-ready structural and electrical documentation. Below are 11 things we wish every applicant knew before filing. Think of this as a chat over coffee with the folks who live and breathe Florida permitting at 1 Contractor Solutions.

1. Confirm Whether You Are in the City of Naples or Collier County

This is step zero, and it trips up more people than you would think. A Naples mailing address does not guarantee City of Naples jurisdiction. Plenty of Naples-addressed homes sit in unincorporated Collier County, and the two authorities have different checklists, portals, and reviewers.

Verify jurisdiction by the property address before you submit anything. Filing with the wrong office wastes days you cannot get back. If you want a hand sorting it out, our Naples permitting team page and our Collier County page are good starting points.

2. Yes, You Need a Permit Before Installing PV

Short answer to the most common question: yes. A solar permit in the Naples area is generally required before installing a photovoltaic system. That includes rooftop arrays and ground-mounted systems. Installing first and asking questions later can lead to stop-work orders, fines, and costly retrofits.

If work has already happened without a permit, do not panic. There is a path forward, and our guides on after-the-fact solar installation in Florida and whether solar companies can legalize unpermitted installs walk through it.

3. Know How Each Authority Wants You to Submit

The City of Naples directs applicants to submit electronically through its public portal. Collier County also uses an online portal, and its solar (PRSO) submittal asks you to select the proper application type, list work items, give the location, and add contractor and contact details.

Here is a quick side-by-side to keep handy:

4. Build a Dimensioned Roof Plan That Reviewers Love

For rooftop systems, the City of Naples solar guidelines ask for a dimensioned roof plan. This is where many first-time submittals get kicked back. A solid roof plan shows:

• Roof features and the proposed array layout
• System size and total array area
• Applicable wind-uplift zones and pressures
• Roof perimeter width
• Roof-deck and roof-covering details
• Roof condition and required clearances
• Penetration-flashing details

Missing even one of these can trigger a correction notice. If you are weighing whether to build these in-house, our architectural drafting service handles permit-ready roof plans.

5. Expect Structural Documentation, Not Just a Spec Sheet

Reviewers are not just checking that panels exist. They want proof your roof can carry them. Naples structural guidance calls for documentation covering:

1. Panel wind resistance
2. Support framing performance under uplift and lateral forces
3. The structure's capacity for added dead load
4. Connection design

The City specifies signed and sealed drawings and calculations for applicable requirements. That means a Florida-licensed engineer is involved, not just a drafter. If you are wondering who does what, read who seals structural drawings for Florida permits, and see our structural engineering page for how in-house sealed drawings keep things moving.

6. Get the Electrical Package Right the First Time

Electrical plans for a Naples solar permit should be designed to NEC Article 690. The City asks for a complete diagram, equipment locations, load calculations, and a riser diagram. Collier County wants a riser diagram showing wire sizes and types plus junction boxes and combiners, along with equipment listings and technical sheets.

A clean, consistent electrical set is one of the fastest ways to avoid resubmittals. If you are filing multiple systems, our MEP engineering support can standardize your drawings so every job follows the same reviewer-friendly format.

7. Know When a Florida-Registered Engineer Is Required

Not every system needs a full engineered electrical set, but some do. According to City of Naples guidance, a Florida-registered electrical engineer must prepare and digitally sign plans when the system value exceeds $50,000, or when service capacity thresholds are exceeded.

Large residential systems with battery storage and commercial rooftops can cross these lines quickly, so check early rather than discovering it at plan review.

8. Ground Mounts in Collier County Have Extra Homework

Ground-mounted solar adds site-planning requirements. Collier County requires a proposed site plan for ground-mounted systems, and its checklist flags a possible certified site-plan or survey requirement when new impervious area exceeds 400 square feet.

If the property is on septic, show the proposed structure's distance from the septic system. The county checklist cites a minimum 5-foot separation under Florida Administrative Code 62-6.005(2). Missing that dimension is a classic reason for a correction request. Our site plan service takes care of these details.

9. Budget for Fees, and Confirm Them Before You Do

Fees depend on jurisdiction, scope, and any associated trade permits. The City of Naples solar permit document lists a $150 fee for the solar permit itself. It also lists other trade permits at $0.15 per square foot of gross structure area, with a $125 minimum.

Naples' electrical permit application lists $0.10 per square foot of gross structure area (with a $125 minimum) plus a plan-review fee equal to 20% of the permit fee. Whether that applies to your specific solar project is something to confirm with the City. Official sources do not publish a single total project fee, so treat any number as a starting point and verify the current schedule before budgeting.

10. Do Not Count on a Standard Review Timeline

Here is the honest truth: the official Naples and Collier sources do not state a standard solar-permit review timeline. Review time depends on completeness of your package, reviewer workload, and whether corrections are needed.

What you can control is submittal quality. A complete package on the first try beats a fast but sloppy one every time. Common mistakes are covered in 7 solar permit filing mistakes in Orange County, FL, and the lessons apply just as well in Naples. For solar firms running multiple jobs, how to speed up solar permit expediting in Florida offers practical tips.

11. Plan for Separate Trade Permits and Closeout

A solar permit can come with companion requirements, such as separate electrical or other trade permits, plus inspections. Ask your reviewer or permitting partner early which ones apply to your scope so nothing surprises you at final.

If your plans get rejected, do not despair. Our guide on how to resubmit plans in Florida and the article on who can rescue a denied building permit in Florida show how to turn a denial into an approval. And if a permit lapses mid-project, see our expired solar permit fix-it guide.

A Quick Checklist Before You Submit

Use this list as a final gut check before hitting submit:

• Jurisdiction confirmed (City of Naples or Collier County)
• Current checklist and fee schedule verified
• Dimensioned roof plan or site plan complete
• Signed and sealed structural drawings and calculations
• NEC 690 electrical diagram with riser and load calcs
• Equipment listings and technical sheets attached
• Septic separation shown for ground mounts, if applicable
• Engineer requirement checked against the thresholds above
