Is solar worth it in Florida?

Florida gets good sunshine — about 5.3 peak sun hours a day — and residential electricity runs around $0.15/kWh. For a typical $150-a-month power bill, that points to roughly a 7.8-kW system costing about $23,262 — with no federal tax credit, which ended for installations completed after December 31, 2025 — paying for itself in about 12.9 years and netting on the order of $38,103 over 25 years. Your own numbers will differ — the calculator above uses your real bill.

The Sunshine State lives up to the name with strong production, and Florida still offers full 1:1 retail net metering, so exported power is credited at full value. Cheap-ish electricity tempers savings a little, but payback is generally good.

What changes the math in Florida

• Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Florida sits at about $0.15.
• Sun hours — more sun means a smaller, cheaper system covers the same usage. Florida averages ~5.3 hours.
• Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
• Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.

Florida: the rules that actually decide your payback

Who your utility is, and why it matters

Florida Power & Light serves the largest share of the state, with Duke Energy Florida and Tampa Electric covering much of the rest — all three regulated by the Florida Public Service Commission. Municipal utilities including JEA in Jacksonville and OUC in Orlando, plus the electric cooperatives, serve several million more customers and are not bound by the PSC's net-metering rule. Which category you fall into determines whether the rules below are yours.

What your exported power is worth

For PSC-regulated investor-owned utilities, Florida rule 25-6.065 requires net metering, and residential systems at the smallest tier get expedited interconnection with no separate application fee. Excess generation is carried forward as a kWh credit month to month and trued up once a year, with any remaining surplus paid at a wholesale avoided-cost rate rather than retail. That annual true-up is the detail that matters when sizing: generating far beyond your own annual consumption converts the surplus from retail-value credit into low-value cash.

The Florida incentive layer

Florida has no state income tax, so there is no state solar tax credit. Two exemptions do real work instead: solar equipment is exempt from state sales tax, and residential renewable energy source devices are excluded from property-tax assessment, so a system does not raise your assessed value. Utility-level rebates have historically been limited and oversubscribed.

Battery and self-consumption

The Florida case for storage is driven less by economics than by weather. Grid-tied solar without storage shuts down during an outage for the safety of line crews, which surprises people who bought panels partly for hurricane resilience. If riding out a multi-day outage is a goal, that requires a battery and the right inverter architecture — and it should be priced as a resilience purchase, because full retail net metering already captures most of the bill savings available.

What to check on a Florida quote

• Confirm whether your provider is PSC-regulated or a municipal utility or co-op — the net-metering rule only binds the first group.
• Ask what rate the annual true-up pays for surplus, and size the system against your actual annual usage rather than beyond it.
• Ask for the wind-load rating of the mounting system and confirm it suits your county's requirements.
• Have the roof's age and remaining life assessed before install — removing and refitting an array for a re-roof is a costly avoidable step.
• Notify your home insurer and ask in advance how the array affects your policy and your deductible.
• If resilience matters, ask explicitly what happens during an outage — and do not assume panels alone will keep the lights on.
