Port St. Lucie homes are served by FPL and pay about 15.4 cents per kWh (EIA, April 2026). A 6 kW roof at ZIP 34952 is modeled near 9,276 kWh a year (NREL PVWatts). Unlike Miami and Fort Lauderdale, Port St. Lucie sits outside the High-Velocity Hurricane Zone, so your racking uses standard Florida Product Approval, not the stricter Miami-Dade regime.
- Serving utility: Florida Power & Light (FPL), which covers Port St. Lucie and most of St. Lucie County (FPL service area, as of 2026); confirm your own address with FPL, since neighboring Fort Pierce is served by the municipal utility FPUA instead.
- Florida residential rate: about 15.4 cents per kWh (EIA, as of April 2026).
- Modeled production, 6 kW system at ZIP 34952: about 9,276 kWh per year (NREL PVWatts v8).
- Net metering: retail-rate credit, roughly one-for-one, under Florida PSC Rule 25-6.065; verify FPL’s current tariff.
- Roof rule: St. Lucie County is a wind-borne debris region but is outside the High-Velocity Hurricane Zone, so mounting hardware needs standard Florida Product Approval rather than a Miami-Dade Notice of Acceptance; verify your address’s design wind speed.
Port St. Lucie is one of the fastest-growing large cities in Florida, and much of that growth is brand-new construction with fresh roofs, which happens to be close to ideal for rooftop solar. The sun, the year-round air-conditioning bills, and Florida’s retail net-metering deal all make solar pay here, so the real question is not whether solar works in Port St. Lucie but what it costs and what is different about doing it in St. Lucie County. Your power comes from Florida Power & Light, the state’s largest utility, and, unlike Miami or Fort Lauderdale, your roof sits outside the High-Velocity Hurricane Zone. This page covers what solar costs here, how FPL credits your power, the Florida incentives that still apply in 2026, and the permitting that is specific to the City of Port St. Lucie.
Why solar in Port St. Lucie is different: outside the hurricane zone, but still coastal
The thing that sets Port St. Lucie apart from Miami and Fort Lauderdale is what it is not: it is outside the High-Velocity Hurricane Zone. The HVHZ is a special part of the Florida Building Code, written after Hurricane Andrew, that covers only Miami-Dade and Broward Counties (Florida Building Commission, as of 2026). St. Lucie County is not in it. In practice that means your mounting hardware needs a standard Florida Product Approval rather than a Miami-Dade Notice of Acceptance, and your installer works to the county’s design wind speed rather than the tougher HVHZ numbers a Miami or Broward roof carries. That usually makes the paperwork and the product choices simpler than a Miami-Dade install, though a careful installer still engineers the attachment to your specific roof.
Simpler than Miami does not mean casual. St. Lucie County still sits in Florida’s wind-borne debris region, with an ultimate design wind speed near 150 mph for a typical home (Risk Category II) under the Florida Building Code and ASCE 7; the exact figure is roof-specific, so verify it for your address. Homes near the North Fork of the St. Lucie River or the barrier island also deal with salt air, so ask your installer about corrosion-resistant, marine-grade hardware. The takeaway: your racking must be engineered and product-approved for your roof’s wind load, just not to Miami-Dade’s HVHZ standard.
How FPL credits your solar: net metering and the December true-up
Short answer: FPL banks your surplus solar as kilowatt-hour credits at the full retail rate, then trues up once a year in December. FPL nets your solar against your usage each month and credits any surplus in kilowatt-hours, not dollars. When your panels make more than you use in a billing month, FPL carries the extra kilowatt-hours forward to later months, offsetting power you pull from the grid at the full retail rate (FPL net metering). This one-for-one retail framework follows Florida Public Service Commission Rule 25-6.065 (DSIRE, Florida net metering; verify current terms). For the mechanics of export credits, see how net metering credits your solar exports, and for the full FPL rules read our FPL net metering guide and the statewide Florida net metering explainer.
The part people miss is the annual true-up. FPL reads your meter each December, and if you still have banked kilowatt-hours after a year of netting, FPL pays those out as a credit at its avoided-cost rate, not the full retail rate. That avoided-cost rate moves with fuel costs and is worth noticeably less per kilowatt-hour than an on-bill credit, so the smart move is to size a system close to your annual usage rather than oversizing it to chase a big December surplus.
| What you earn | How it is valued |
|---|---|
| Monthly net-metering credit | One-for-one retail kWh credit; surplus banks month to month |
| Annual December true-up | Leftover bank paid at FPL’s avoided-cost rate, below retail |
| System sizing rule | Estimated to produce under 115% of your annual usage; verify with FPL |

What solar costs in Port St. Lucie in 2026
Cash prices for a typical Port St. Lucie home run in the same range as the rest of FPL territory, and the payback is driven by how much FPL power your roof replaces. According to MySolarFY’s analysis (August 2026), a right-sized 6 kW system in Port St. Lucie modeled at about 9,276 kWh a year offsets roughly $1,425 of FPL power in its first year at Florida’s 15.4 cents per kWh average rate. That first-year offset grows over time as electricity rates rise, which is what pulls a Florida payback into the roughly 10 to 13 year range for a well-sized cash system. For the full statewide math, see our Florida solar cost guide, and to weigh payback, read whether solar panels are worth it.

| Modeled 6 kW production (ZIP 34952) | About 9,276 kWh per year (NREL PVWatts v8) |
| Hurricane-zone status | Outside the HVHZ; wind-borne debris region near 150 mph design wind speed |
Florida incentives that still apply in 2026
Florida has no state solar tax credit, but it does add two exemptions, and they still apply in 2026. Florida exempts residential solar equipment from state sales tax, and it does not add the panels’ value to your property tax assessment, so going solar does not raise your property taxes (DSIRE, Florida incentives; verify current terms). Florida has no state income tax, so there is no state income-tax credit to claim, which is just how the state’s tax system works rather than a gap in the deal.
The 30% federal residential credit (Section 25D) ended for expenditures made after December 31, 2025 (IRS), so a 2026 Port St. Lucie system does not carry that federal credit. Any installer quote that still promises a 30% federal homeowner credit for a 2026 install is out of date, so treat it as a red flag. On a lease or PPA the company that owns the panels keeps the net-metering credits and the tax exemptions, and you do not get the federal credit; your benefit is a lower or fixed power price with no up-front cost. Read the contract for any annual escalator, because total lease or PPA payments over 20 to 25 years may exceed the cost of buying the same system in cash.
Permitting solar with the City of Port St. Lucie
Most Port St. Lucie homes are inside city limits, so your residential solar permit is pulled with the City of Port St. Lucie Building Department, not the county; homes in unincorporated St. Lucie County permit through the county instead (City of Port St. Lucie Building Department; verify current requirements). After the permit and inspections, FPL must approve the interconnection and grant permission to operate before you switch the system on, which is the same final step every FPL customer goes through. A licensed Florida solar contractor normally manages this whole process, and because Port St. Lucie is outside the HVHZ, the plan review is generally lighter than a Miami-Dade or Broward submittal. For the questions to ask before you sign, see the right questions to ask a solar installer.
How Port St. Lucie compares to nearby FPL cities
Port St. Lucie shares FPL and Florida’s retail net metering with the big FPL metros to the south, but the roof rules and the growth story are different. In Miami and Fort Lauderdale, the roof sits in the High-Velocity Hurricane Zone, which raises the design wind speed, narrows the approved hardware, and adds Miami-Dade or Broward paperwork. Port St. Lucie skips that HVHZ layer, and its building boom means a lot of newer roofs that are ready for panels without a re-roof first.

Frequently asked questions about Port St. Lucie solar
Which utility serves Port St. Lucie for solar?
Florida Power & Light (FPL) serves Port St. Lucie and most of St. Lucie County, and FPL credits rooftop solar under Florida’s retail net-metering rules. Neighboring Fort Pierce is served by the municipal utility FPUA instead, so confirm your own address with your provider.
Is Port St. Lucie in the High-Velocity Hurricane Zone?
No. The High-Velocity Hurricane Zone covers only Miami-Dade and Broward Counties. Port St. Lucie is in St. Lucie County, which is outside the HVHZ, so your solar racking needs standard Florida Product Approval rather than a Miami-Dade Notice of Acceptance, at a design wind speed near 150 mph; verify the figure for your address.
Does Florida still have a solar tax credit in 2026?
Florida has no state solar tax credit, but it does exempt residential solar from state sales tax and from added property tax assessment. The 30% federal residential credit (Section 25D) ended for expenditures made after December 31, 2025, so a 2026 install does not carry it.
How much power does a Port St. Lucie solar system produce?
A 6 kW rooftop system at ZIP 34952 is modeled near 9,276 kWh a year by NREL PVWatts. At Florida’s average residential rate of about 15.4 cents per kWh, that offsets roughly $1,425 of FPL power in the first year, with the offset growing as rates rise.
