Is Solar Worth It in Florida?

Two things generally work in a Florida homeowner’s favor. The first is sunlight: Florida receives strong solar resource for most of the year, and a well-oriented, unshaded roof can produce a meaningful amount of electricity. The second is consumption: air conditioning runs for a long season here, so many Florida households use more electricity than the national household norm, which means each kilowatt-hour a solar system offsets has more work to do.

Cost of electricity matters too. Florida’s average retail electricity price across all customer sectors was 12.53 cents per kilowatt-hour in 2024, according to the U.S. Energy Information Administration.¹ That is a statewide, all-sector figure and is not your rate — residential rates and monthly charges differ by utility, and your own bill is the authoritative source for what you actually pay.

Sunlight is an input, not a conclusion. Two homes on the same street can get identical sunshine and reach opposite decisions, because the economics depend on things sunshine does not control: how many kilowatt-hours the household actually uses, what portion of the roof faces a productive direction, how much shade falls across it during peak hours, what the utility charges regardless of usage, and how much the system costs after financing.

The U.S. Department of Energy’s National Renewable Energy Laboratory publishes PVWatts, a free calculator that estimates production for a specific address, roof tilt, and orientation.² Running your own address there is a useful reality check against a salesperson’s production estimate — it is an independent, government-built model rather than a number produced by the company selling you the system.

Solar offsets electricity you would otherwise buy. That makes your usage the single most useful starting number. Pull twelve months of bills and look at annual kilowatt-hours, not just dollars — dollars move with rates, and kilowatt-hours describe your home.

• A household using a large amount of electricity year-round has more to offset, so the same system does more financial work.
• A household with modest usage may find the fixed costs of a solar project harder to justify.
• Planned changes matter: an electric vehicle, a pool pump, a home addition, or a family member moving in or out can shift usage substantially.

For how those kilowatt-hours turn into an actual savings estimate — and which assumptions to challenge — see how much solar could really save you.

Florida is not one utility territory. Investor-owned utilities, municipal utilities, and rural electric cooperatives all serve Florida homes, and their rates, fixed charges, interconnection processes, and treatment of excess solar energy are not identical. Two homeowners with the same system and the same usage can see different bills because they are served by different utilities.

Before you evaluate any proposal, understand how your specific utility handles customer-owned solar. Our guide to Florida net metering explains the framework and how to verify your own terms, and what happens to your electric bill after going solar covers why a bill usually does not disappear entirely.

Roof condition, material, orientation, and shading determine both whether a system performs and whether the project timing makes sense. Installing on a roof with only a few years of life left often means paying to remove and reinstall the array later.

• Roof age and remaining life — see whether you should replace your roof first.
• Shading from trees, chimneys, or neighboring structures during midday hours.
• Usable, well-oriented roof area, including how the array must be laid out around vents and setbacks.
• Structural condition and any existing leaks or repairs.

These physical questions are covered in depth in is solar right for your home, should you replace your roof before installing solar, and will trees or roof shade prevent solar.

Solar economics are long-term. Most of the benefit accrues over years of avoided electricity purchases, so a short ownership horizon changes the analysis substantially. If you may sell soon, the relevant questions become how a system affects a sale, whether a loan or lease transfers, and what a buyer’s lender requires — not simply what you would save annually.

There is no guaranteed effect on resale value, and we would treat any promise of a specific home-value increase with skepticism.

Paying cash, financing with a loan, or signing a lease or power purchase agreement produce very different outcomes from the same hardware. Financing can make a project accessible, but dealer fees, interest, and long terms can raise the total amount paid well above the cash price. The Federal Trade Commission’s consumer guidance on residential solar covers getting multiple bids, checking licensing, and reading lease and power-purchase terms carefully.⁴

Compare structures in cash, loan, lease, or PPA, and see what solar actually costs in Florida for why a low monthly payment is not the same thing as a low price.

Do not build your decision on an incentive you have not confirmed is currently available. The federal Residential Clean Energy Credit equaled 30% of the cost of qualifying property installed from 2022 through December 31, 2025, and the IRS states the credit is not available for property placed in service after December 31, 2025.³ If a proposal, calculator, or older article reduces your price by 30% for a new installation today, that assumption needs to be verified rather than accepted.

Florida-specific tax treatment and utility programs are covered in Florida solar incentives explained. Tax questions about your own return belong with a qualified tax professional.

Two topics come up in nearly every Florida solar conversation, and both deserve careful, unglamorous answers rather than marketing claims. The first is insurance: coverage, deductibles, and how a roof-mounted system is treated vary by insurer and policy, so the only reliable answer comes from your own carrier, in writing, before you sign a contract.

The second is outages. A standard grid-tied solar system without storage generally does not power a home during a utility outage. If resilience is your primary motivation, read do I need a battery before assuming panels alone will keep the lights on.

Florida law limits the ability of ordinances, deed restrictions, and similar instruments to prohibit the installation of solar collectors on a home.⁵ That does not mean an association has no say over anything, but a flat “our HOA does not allow solar” is worth examining rather than accepting. See can my HOA restrict solar.

• You use a substantial amount of electricity year-round and have twelve months of bills to prove it.
• You have a structurally sound roof with years of life left, and usable unshaded area during midday hours.
• You expect to own the home long enough for a long-horizon investment to make sense.
• You can pay cash or qualify for financing whose total cost you have actually calculated — not just the monthly payment.
• You understand how your utility treats customer-owned solar and have confirmed it directly.

• Your roof needs replacement in the next several years and you have not priced doing that first.
• Heavy shade covers most of your usable roof during the middle of the day.
• Your electricity usage is low, which shrinks what solar can offset.
• You may sell within a few years.
• The only affordable path is a financing structure whose total repayment you have not been shown clearly.
• A company is pressuring you to sign today, or the proposal relies on incentives nobody has verified.

If any of these apply, waiting is a legitimate outcome — and often a cheaper one than a poorly timed installation. For the sales tactics worth recognizing, see solar scams and red flags to avoid.
