Choosing the right solar installer is the single most consequential decision in your solar journey. The same 8 kW system can cost $19,000 from one company and $27,000 from another -- with identical panels on your roof. The difference comes down to markup, dealer fees, and how much homework you have done before you sign.
This guide gives you everything you need to evaluate, compare, and choose a solar installer in Florida with confidence. No company recommendations -- just the tools and knowledge to make the right call for your home.
Florida Licensing Requirements
Florida law requires that anyone installing a solar energy system hold a valid state contractor license. This is non-negotiable. An unlicensed installation is illegal, voids manufacturer warranties, may not pass inspection, and leaves you with zero legal recourse if something goes wrong.
Accepted License Types
| License Type | Code | Scope |
|---|---|---|
| Electrical Contractor | EC | Full electrical work including solar PV installation, wiring, and grid interconnection. The most common license type for solar installers in Florida. |
| Certified Solar Contractor | CVC | Specifically covers solar energy system installation. Previously called the "Solar Contractor" license. Covers both PV and solar thermal. |
| Certified General Contractor | CGC | Covers general construction including solar installation. Some larger companies operate under this license with licensed electricians on staff. |
How to Verify a License
- Go to myfloridalicense.com
- Search by company name or license number
- Confirm the license is active (not expired, suspended, or revoked)
- Check for any disciplinary actions or complaints on file
- Verify the license type is EC, CVC, or CGC
Pro Tip
Ask for the license number upfront. A legitimate installer will provide it without hesitation. If they dodge the question or say they work "under" another company's license, that is a warning sign. The company that signs your contract must hold the license.
NABCEP Certification
NABCEP (North American Board of Certified Energy Practitioners) is the gold standard voluntary certification in the solar industry. It is not legally required in Florida, but it demonstrates that the installer or their design team has passed rigorous exams covering system design, installation best practices, safety, and code compliance.
NABCEP Certification Levels
| Certification | What It Means | Why It Matters |
|---|---|---|
| NABCEP PV Installation Professional | Passed comprehensive exam on solar PV installation | The installer knows current best practices and codes |
| NABCEP PV Design Specialist | Expertise in system design and engineering | Your system will be optimally designed for your roof and usage |
| NABCEP PV Associate | Entry-level certification for solar professionals | Shows commitment to professional development |
When evaluating installers, ask whether they have NABCEP-certified designers or installers on staff. A company does not need every employee to be NABCEP-certified, but having certified professionals on the design and installation teams is a strong quality indicator.
Insurance Requirements
Before any work begins on your roof, verify that the installer carries adequate insurance. This protects you from liability if a worker is injured on your property or if the installation causes damage.
Required Insurance Coverage
- General Liability Insurance: Minimum $1,000,000. Covers property damage and bodily injury claims. If an installer damages your roof, siding, or landscaping, this covers repairs.
- Workers' Compensation Insurance: Required by Florida law for companies with 1 or more employees in the construction industry. If a worker falls off your roof and the company does not carry workers' comp, you could be liable.
- Vehicle Insurance: Covers damage from company vehicles on your property.
Verify, Do Not Trust
Ask for a Certificate of Insurance (COI) before signing. Call the insurance company listed on the COI to confirm the policy is current. Some unscrupulous contractors provide expired or fraudulent COIs. It takes one phone call to verify.
15 Questions to Ask Any Solar Installer
Print this list or save it on your phone. Ask every single installer these questions and compare their answers side by side.
Licensing and Credentials
- What is your Florida contractor license number and type? -- Verify at myfloridalicense.com before the appointment ends.
- Do you have NABCEP-certified installers or designers on staff? -- Not required, but a quality signal.
- Can I see your Certificate of Insurance? -- General liability and workers' comp. Call to verify.
Equipment and Design
- What panel brand, model, and wattage will you install? -- The contract must specify exact equipment. "Tier 1 panel" is not an answer.
- What inverter type and brand? -- String, string + optimizers, or microinverters. Each has trade-offs.
- What mounting/racking system do you use? -- For Florida, ask if it has a Miami-Dade NOA (Notice of Acceptance) for hurricane-zone compliance. See our hurricane-proof solar guide.
- How did you calculate the system size for my home? -- Should be based on your actual electricity usage history, not a generic estimate.
Cost and Financing
- What is the total installed cost if I pay cash? -- This is the true cost. Everything else is built on top of this number.
- What is the cost per watt? -- In Florida in 2026, expect $2.40-$3.20 per watt. See our Florida Solar Cost guide.
- Are there any dealer fees, origination fees, or hidden charges? -- Some financing options add 15-30% in dealer fees to the system cost. Ask for an itemized breakdown.
Warranties and Support
- What warranties do you provide? -- Get panel warranty, inverter warranty, and workmanship warranty terms in writing.
- What does your workmanship warranty cover specifically? -- Roof penetrations? Wiring? Racking? Water damage from installation?
- What happens to my warranty if your company closes? -- Panel and inverter warranties survive. Workmanship warranty may not.
Timeline and Process
- What is the estimated timeline from contract to Permission to Operate? -- Typical Florida timeline: 4-12 weeks. Ask for a breakdown: design, permitting, installation, inspection, utility approval.
- Who handles permitting and utility interconnection? -- The installer should handle both. If they ask you to pull your own permits, that is unusual and potentially a red flag.
Red Flags to Walk Away From
These are deal-breakers. If you encounter any of these, end the conversation and move on to another installer.
Immediate Disqualifiers
- Claims the federal residential tax credit is still available. The residential solar ITC expired on December 31, 2025. Any installer still advertising this is either uninformed or deliberately misleading you. Either way, you cannot trust them with a $20,000+ purchase. See our incentives guide.
- Requires a same-day signature. "This price expires today" is a high-pressure sales tactic. Legitimate pricing does not evaporate overnight. Always take at least 48 hours to review any solar contract.
- No Florida contractor license (EC, CVC, or CGC). Illegal. Full stop. No license means no legal recourse, no warranty enforcement, and potentially no building inspection approval.
- Claims government affiliation. No government agency sends representatives door-to-door to sell solar panels. If someone claims to be from a "government solar program," they are lying.
- Too-good-to-be-true pricing. If a quote is dramatically lower than every other quote you have received, something is missing. Cheap panels, no workmanship warranty, hidden dealer fees, or an inexperienced crew cutting corners.
- Refuses to provide references. Established, reputable installers are happy to connect you with recent customers. Refusal is a clear warning sign.
- Vague about equipment. Your contract must specify the exact panel make, model, wattage, and quantity. "We use premium panels" is not a specification.
- No physical office in Florida. If they cannot give you a Florida street address (not a P.O. box), you will have difficulty reaching them for warranty service.
How to Compare Solar Quotes
The single most important thing you can do: get at least 3 quotes, ideally 4 to 5. Include a mix of large national companies and smaller local or regional installers.
Apples-to-Apples Comparison Checklist
| Comparison Factor | What to Look For | Red Flag |
|---|---|---|
| System size (kW) | All quotes should be for the same or similar size | One quote is significantly larger or smaller than others |
| Panel specs | Same or equivalent panel brand, model, wattage | Quote does not specify exact panel model |
| Inverter type | Same type across quotes (microinverter vs. string) | Switching inverter type without explaining why |
| Cash price | Total installed cost without financing markup | Quote only shows a monthly payment, never the total cost |
| Cost per watt | $2.40-$3.20/W in Florida (2026) | Below $2.00/W or above $3.50/W without explanation |
| Estimated production (kWh/yr) | Should be within 10% across similar-sized systems | Wild differences in production estimates |
| Workmanship warranty | 10-25 years | Less than 10 years or "limited" with no details |
| Dealer fees | Should be disclosed upfront | Hidden fees that only appear in financing documents |
The Cash Price Is King
Always ask for the cash price first. This is the true cost of the system. Financing adds interest and fees. Compare all quotes at their cash price, then separately evaluate financing options. Never compare a cash price from one company to a financed monthly payment from another.
Reading a Solar Proposal
A professional solar proposal from a Florida installer should contain the following sections. If any are missing, ask for them before signing.
What a Complete Proposal Includes
- Site assessment summary: Roof orientation, tilt, shading analysis (ideally using satellite imagery or on-site measurement), and available roof area.
- System design: Panel layout diagram showing exactly where each panel goes. Number of panels, total system size in kW DC, and inverter configuration.
- Equipment specifications: Exact make and model for panels, inverter(s), racking system, and monitoring hardware. Data sheets should be available on request.
- Production estimate: Estimated annual energy production in kWh based on your specific roof, ideally from PVWatts or similar modeling software. Month-by-month breakdown is a plus.
- Financial analysis: Total installed cost (cash), cost per watt, estimated annual savings, estimated payback period, and 25-year savings projection. Should reference current Florida electricity rates and net metering.
- Warranty summary: Panel manufacturer warranty, inverter warranty, and installer workmanship warranty -- all with specific terms and durations.
- Timeline: Estimated dates or durations for design finalization, permitting, installation, inspection, and utility interconnection (PTO).
- Financing terms (if applicable): Interest rate, loan term, monthly payment, total cost of financing over the loan term, and any dealer fees.
Numbers That Should Add Up
- System size (kW) x 1,400-1,600 kWh/kW = Estimated annual production in Florida (varies by location, shading, and roof orientation)
- Cash price / system size (watts) = Cost per watt (should be $2.40-$3.20 in Florida 2026)
- Annual production x electricity rate = Approximate annual savings from solar
- Cash price / annual savings = Simple payback period in years
Warranty Expectations
Your solar system involves three separate warranties. Understand each one and get all terms in writing before signing your contract.
| Warranty Type | What It Covers | Typical Duration | Who Backs It |
|---|---|---|---|
| Panel Manufacturer | Product defects and power output degradation (typically guarantees at least 80-85% output at year 25) | 25-40 years | Panel manufacturer |
| Inverter Manufacturer | Inverter hardware defects and failure | 12-25 years (microinverters typically 25 years; string inverters 12-15 years) | Inverter manufacturer |
| Installer Workmanship | Installation quality: roof penetrations, wiring connections, racking integrity, water intrusion from installation | 10-25 years | Your installer |
The Workmanship Warranty Is the Most Important
Panel and inverter warranties survive even if your installer goes out of business -- you deal directly with the manufacturer. But a workmanship warranty dies with the company. This is why the financial stability and track record of your installer matters. A 25-year workmanship warranty from a company that has been in business for 2 years is worth less than a 15-year warranty from a company with a 15-year track record.
What Warranties Typically Do NOT Cover
- Hurricane or storm damage (that is what homeowners insurance covers)
- Damage from tree limbs, debris, or animals
- Cosmetic issues that do not affect performance
- Damage from unauthorized modifications or repairs
- Power output losses from dirt, pollen, or lack of maintenance
Financing Pitfalls
Financing solar can be smart, but it is also where most homeowners get taken advantage of. Here are the common pitfalls to watch for in Florida.
Dealer Fees (The Hidden Markup)
Many solar loans include dealer fees (also called origination fees or finance charges) that add 15-30% to the system cost. A system with a $22,000 cash price might become a $28,000 loan. The installer gets the full amount at signing. You pay the inflated price over the loan term.
Always compare the financed total cost to the cash price. If the financed total is more than 5-10% above the cash price (accounting for interest), excessive dealer fees are likely baked in.
Common Financing Options Compared
| Financing Type | Typical Rate | Pros | Cons |
|---|---|---|---|
| Home equity loan / HELOC | 6-8% | Lowest rates; interest may be tax-deductible; no dealer fees | Uses your home as collateral; requires equity |
| Solar loan (no dealer fee) | 5-9% | No home equity required; competitive rates | Higher rates than HELOC; less common |
| Solar loan (with dealer fee) | 1-6% (deceptively low) | Low advertised rate | 15-30% dealer fee inflates total cost; true cost of capital is much higher than the rate suggests |
| PACE financing | 6.5-9% | No money down; long terms (up to 25 years); repaid through property taxes | Higher rates; lien priority over mortgage; can complicate refinancing or sale |
| Solar lease / PPA | N/A | No upfront cost; maintenance included | You do not own the system; 10-20% bill savings instead of 80-100%; escalator clauses can increase payments annually |
Watch Out for "Zero Percent" Solar Loans
A 0% or 0.99% solar loan sounds amazing, but the interest is almost always prepaid through a large dealer fee. A $22,000 system financed at "0%" might actually cost $28,000-$30,000 when the dealer fee is included. Always ask for the total amount financed and compare it to the cash price. That difference is your real financing cost.
PACE Financing: Specific Florida Considerations
PACE (Property Assessed Clean Energy) is popular in Florida, but it comes with unique risks:
- PACE liens take priority over your mortgage. Some mortgage lenders (especially Fannie Mae and Freddie Mac) will not approve a refinance while a PACE lien is active.
- If you sell your home, the PACE assessment transfers to the buyer. Some buyers or their lenders may object.
- Interest rates are typically 6.5-9%, which is higher than home equity loans.
- PACE is repaid through your property tax bill. If you fail to pay, it can lead to a tax lien on your home.
PACE can make sense for homeowners who lack home equity or prefer no-money-down options, but compare it carefully against a HELOC or standard solar loan.
National vs. Local Installers
| Factor | National Companies | Local / Regional Companies |
|---|---|---|
| Pricing | Higher ($2.70-$3.20/W) | Lower ($2.40-$2.80/W) |
| Warranty | Often more comprehensive | Varies; some match or exceed nationals |
| Financial stability | Stronger (publicly traded) | Varies; check years in business |
| Florida code knowledge | Good but may rely on subcontractors | Typically excellent; deep local permitting experience |
| Installation timeline | Often slower (6-12 weeks) | Often faster (3-6 weeks) |
| Customer service | Call center model | Direct owner or project manager access |
| Financing options | More options (lease, PPA, loan) | Cash, loan, PACE typically |
| Hurricane-zone experience | Varies; ask specifically | Often deep, especially in South FL |
Our Recommendation
For most Florida homeowners, a well-established regional or local installer offers the best combination of competitive pricing, local code expertise, and personal service. But always include at least one larger national company in your quotes for comparison. The best deal is the one you find through thorough comparison, not brand loyalty.

Get Your Free Solar QuotesFrequently Asked Questions
What license does a solar installer need in Florida?
Florida solar installers must hold an active EC (Electrical Contractor), CVC (Certified Solar Contractor), or CGC (Certified General Contractor) license. Verify at myfloridalicense.com.
What is NABCEP certification and does my installer need it?
NABCEP is the gold standard voluntary certification for solar professionals. Not legally required in Florida, but it demonstrates rigorous training and knowledge. Prioritize companies with NABCEP-certified staff.
How many solar quotes should I get?
At least 3, ideally 4 to 5. Include both national and local or regional companies. Compare total installed cost, equipment, warranties, and financing side by side.
What are red flags when choosing a solar installer?
Major red flags: claiming the expired federal tax credit is still available, requiring same-day signatures, unusually low prices, no FL contractor license, claiming government affiliation, no physical Florida office, refusing to provide references, and vague equipment specs.
What should a solar proposal include?
System size, exact panel and inverter specs, estimated production, total cash price, cost per watt, all warranty terms, installation timeline, and financing terms if applicable.
What warranty should I expect?
Three separate warranties: panel manufacturer (25-40 years), inverter (12-25 years), and installer workmanship (10-25 years). Get all terms in writing in your contract.
Is PACE financing a good option in Florida?
PACE can be convenient (no money down, repayment through property taxes), but rates are typically 6.5-9% -- higher than home equity loans. PACE liens take priority over your mortgage, which can complicate refinancing or selling. Compare to other options before committing.
Should I choose a national or local company?
Both can be excellent. National companies offer financial stability and broad warranties. Local companies often provide lower pricing, faster timelines, and deeper Florida code knowledge. Include at least one of each in your comparison.
