For many Florida homeowners, solar still pays off in 2026 — slower than it did before, and with two hidden costs that the marketing materials usually skip.
Payback in Florida for a typical residential system in 2026 falls in the range of 9-13 years, depending on your consumption, system size, utility tariffs, and financing. That's longer than it was when the 30% federal Residential Clean Energy Credit was in effect. The main reason: §25D was repealed for systems installed after December 31, 2025. See our guide on the federal repeal for the federal side.
VERIFIED 2026-06 · irs.govWhat still works in Florida
Florida's state-level incentives didn't change with the federal repeal. They keep solar competitive even without §25D.
1:1 net metering for major IOUs
Florida law requires the four major investor-owned utilities — FPL, Duke Energy Florida, TECO, and FPU — to credit solar exports at the full retail rate.
Three important caveats:
- Net metering rates are declining for new interconnections — recent cohorts may receive less than full retail.
- Year-end surplus is paid at wholesale avoided-cost (~3-5¢/kWh), not retail. Don't oversize your system to chase surplus.
- Municipal utilities and co-ops (OUC in Orlando, JEA in Jacksonville, City of Tallahassee, etc.) are not bound by the 1:1 rule and typically credit far less. If you're on a municipal, the math is very different and our calculator doesn't cover it yet.
Property tax exemption
The added home value from your solar system is exempt from Florida property tax (FL Statute 193.624). No application — it's automatic.

Solar equipment is exempt from Florida's ~6% state sales tax (FL Statute 212.08(7)(hh)), which trims your upfront cost meaningfully on a $20k+ system.

Floridians use a lot of electricity — about 1,142 kWh per month on average, versus ~881 kWh nationally. More consumption means more solar production can offset retail-priced grid power, which means more annual savings per kW installed. That partially compensates for the loss of the federal credit.
The other obvious win: lots of sun.
Two hidden costs sellers don't mention
1. Your roof age
This is the most common surprise. Many Florida home insurers require a roof less than 15 years old to cover a home with solar installed. If your roof is older, you may need to replace it before installing solar — and a Florida roof replacement runs $10,000-25,000.
Payback calculators (including ours) don't include this. If you're 12+ years into your current roof, get a roof inspection and an insurance check before any solar quote.
2. The 10 kW threshold
Florida's Tier 2 net metering rules kick in for systems larger than 10 kW AC. Tier 2 requires:
- A $1 million liability insurance policy
- A $400 application/processing fee
If your install pushes past 10 kW, that's a real recurring cost on top of the hardware. Right-sizing your system close to but under 10 kW is often the smart move — and aligns with the don't-oversize advice from the net metering caveats above.
Hurricane resilience: solar alone won't help
Florida storms regularly cause multi-day grid outages. Grid-tied solar systems shut down when the grid goes down — that's by design, for line-worker safety. To get backup power during an outage, you need a battery system.
A battery is a separate purchase and a separate cost. It doesn't show up in payback math the way solar production does. But for Florida specifically, it's a non-financial value worth weighing alongside the dollar figures.
And the federal credit
The 30% federal Residential Clean Energy Credit (§25D) was repealed for systems installed after December 31, 2025. For 2026 Florida buyers, the federal credit is $0. Don't model 30% into your payback — that's outdated. Read our full guide on the repeal.
Bottom line
Florida solar in 2026 can still pay off. State incentives are intact, the sun is plentiful, and high household consumption gives every kWh you offset real value. But the payback is longer than the §25D-era marketing suggested, and the roof-age and 10-kW-threshold costs are real and nearly every quote glosses over them.
Before you commit:
- Check your roof age and your insurer's solar terms.
- Confirm your utility is an IOU bound by 1:1 net metering, not a municipal.
- Decide whether you want a battery for hurricane resilience.
- Run the actual numbers for your house.
