Solar Panel ROI for South Florida Homes: A 2026 Homeowner's Guide

Is solar worth it for a South Florida home in 2026? The math changed this year, so start with the current numbers. EnergySage puts the average installed cost in Florida at about $2.18 per watt, roughly $31,956 before incentives for a typical 14.65 kW system, with a payback period around 9 to 11 years after state and utility incentives [1]. The federal 30 percent residential clean energy credit ended for expenditures made after December 31, 2025 under Public Law 119-21, so a 2026 installation no longer carries that credit [2]. What remains are Florida's sales- and property-tax exemptions and net metering. This guide breaks down the 2026 ROI for a South Florida homeowner without the expired federal credit baked in.

What solar costs and returns in Florida in 2026

EnergySage's Florida data shows an average installed price near $2.18 per watt, about $31,956 before incentives for the average 14.65 kW system, with a typical range of roughly $27,000 to $37,000 [1]. Estimated payback after state and utility incentives runs about 9 to 11 years, with 25-year net savings in the low tens of thousands [1]. Those figures already reflect the post-federal-credit landscape, which is the correct basis for a 2026 decision.

The single biggest change from older guides is the federal credit. The 30 percent residential clean energy credit (Internal Revenue Code Section 25D) was terminated for expenditures made after December 31, 2025 [2]. Any ROI analysis that still assumes a 30 percent federal credit in 2026 is overstating the return. Underwrite without it.

The incentives that still apply

Two Florida-specific incentives survive and materially improve the math.

Sales-tax exemption. Florida has exempted solar energy systems from the state's 6 percent sales and use tax since 1997 [3]. On a $32,000 system that is roughly $1,900 you do not pay upfront.

Property-tax exemption. State law bars the county property appraiser from including a renewable energy source device in a home's assessed value, an exemption authorized through December 31, 2037 [4]. Your assessment does not rise because you added panels, so the equity you build is not taxed as added value.

Net metering. FPL credits excess generation and requires that a residential system be sized to produce less than 115 percent of annual consumption [5]. Net metering is what converts daytime overproduction into bill offset, and it is central to the payback figure.

How solar affects home value

Owned solar tends to add value at resale, though the premium is not uniform. A Lawrence Berkeley National Laboratory study across eight states found buyers paid roughly $4 per watt of installed PV [6]. Zillow's analysis of 2018 to 2019 sales found solar homes sold for about 4.1 percent more than comparable homes without solar [6]. Two caveats for underwriting: the panels must be owned, not leased, for the premium to travel cleanly, and older studies predate current pricing, so treat these as directional rather than a guaranteed line item.

There is also a Florida-specific reinforcement to the value story. Because state law excludes the panels from your assessed value through 2037 [4], the equity a buyer perceives in the system is not offset by a higher property-tax bill, which is not true of most other value-adding improvements. In other words, a documented, owned system can carry a resale premium without carrying the tax drag that a comparable-dollar renovation would. That combination is part of why owned solar tends to appraise more cleanly in Florida than a leased system or an equivalent cosmetic upgrade.

Why the payback got longer, and why solar can still pencil

The end of the federal credit lengthened payback rather than eliminating the case. Before 2026, a 30 percent credit knocked roughly $9,600 off a $32,000 system on day one, and that single deduction did most of the work in the old five-to-seven-year payback stories. Without it, the payback stretches toward the 9-to-11-year range EnergySage now models for Florida after state and utility incentives [1].

What keeps solar viable is the combination of a rising utility rate and Florida's surviving incentives. FPL's typical residential bill climbed to about $137 a month for a 1,000 kWh customer in 2026 [7], and utility rates in the state have been on an upward path, which increases the value of every kilowatt-hour a rooftop system offsets. The sales- and property-tax exemptions [3][4] plus net metering [5] carry a meaningful share of the return the federal credit used to provide. The honest framing for 2026 is a longer-horizon investment, sized to your consumption, that hedges a rising utility rate, not a quick-payback play.

Owned versus leased, and the resale trap

The value premium and the tax treatment attach to owned systems. A lease or power-purchase agreement transfers the equipment liability and can complicate a sale, because the buyer has to assume or buy out the contract. If the goal is home value and clean resale, own the system. If the goal is only bill reduction with no capital outlay, a lease can still work, but do not expect the resale premium.

If you are weighing a solar install against listing, it is worth confirming what your specific buyer pool credits before you spend. In single-family markets like Coral Gables that conversation belongs in a seller consultation; if you are buying, a buyer consultation can flag which listings already carry owned systems.

Frequently asked questions

Is solar still worth it in Florida in 2026 without the federal credit?

It can be, on a longer horizon. EnergySage's Florida figures show payback around 9 to 11 years after state and utility incentives, on an average installed cost near $2.18 per watt [1]. The 30 percent federal credit ended for expenditures after December 31, 2025 [2], so run the math without it.

What incentives remain for Florida solar?

Florida's 6 percent sales-tax exemption on solar equipment [3], a property-tax exemption that keeps panels out of your assessed value through 2037 [4], and FPL net metering for systems sized under 115 percent of annual consumption [5].

How much does solar add to a Florida home's value?

Berkeley Lab found buyers paid about $4 per watt of installed PV, and Zillow found solar homes sold for about 4.1 percent more than comparable homes [6]. The premium applies to owned systems and should be treated as directional given the age of the data.

Should I buy or lease the system?

Buy it if home value and a clean resale matter, because the tax treatment and resale premium attach to owned systems. A lease reduces bills without capital outlay but can complicate a sale and does not carry the value premium.
