Panels in Port St. Lucie produce roughly 1,520 kWh per kW each year on an unshaded, south-facing roof.

What would a solar estimate look like for a Port St. Lucie home?
Estimates for Port St. Lucie homes at four common bill sizes. Bigger bills need bigger systems that cost more up front, but payback stays about the same, because every kWh the panels make is credited at FPL's full rate. Homes that use more than 1,000 kWh a month pay a higher rate on the extra, so they often do a little better than shown.
| Monthly bill | System size | Panels | Roof space | Cost | Payback |
|---|---|---|---|---|---|
| $150/mo | 6.8 kW | 17 | ~360 sq ft | $18,400 | 13 yrs |
| $200/mo | 9.6 kW | 24 | ~500 sq ft | $25,900 | 13 yrs |
| $300/mo | 15.2 kW | 38 | ~800 sq ft | $41,000 | 13 yrs |
| $400/mo | 21.2 kW | 53 | ~1,110 sq ft | $57,200 | 13 yrs |
How does solar work with FPL in Port St. Lucie?
Port St. Lucie is a fast-growing, mostly owner-occupied Treasure Coast city on FPL that had tornado damage ahead of Hurricane Milton.
Most homes in Port St. Lucie get their electricity from Florida Power & Light (FPL). FPL net meters under the Florida PSC's rule: power your panels send to the grid comes back as a kWh credit at the full retail rate, credits roll forward for up to 12 months, and anything left at year-end is paid out at only a few cents per kWh. So the best Port St. Lucie systems are sized to cover a year of use, not more. See the full FPL solar guide.
Solar can't take your bill below FPL's monthly minimum of about $30.
These estimates apply to homes with mailing addresses in Port St. Lucie, including ZIP codes 34952, 34953, 34983, 34984, 34986, 34987.

Is your Port St. Lucie home a good fit?
About 84% of homes in Port St. Lucie are owner-occupied, and the median owner-occupied home is valued at $369,200, compared with 68% and $359,000 statewide, according to the U.S. Census Bureau (2020-2024 estimates).
- You own the home. Rooftop solar requires owning the roof.
- Your roof gets sun for most of the day on its south, west or east side, without heavy tree shade.
- Your roof has years of life left. Replacing an aging shingle or tile roof before installing saves a removal and reinstall fee later.
- Your FPL bill is regularly over about $150 a month, or you're adding an EV or a pool pump.

How do I choose a solar company in Port St. Lucie?
Check these before you sign with any solar company serving Port St. Lucie:
- A Florida contractor license. Look up the company's license on the Florida DBPR license search and make sure it's active.
- Permits and utility paperwork included. The price should cover the permit with the City of Port St. Lucie or St. Lucie County, inspections and the FPL net metering application.
- Two or three quotes compared on price per watt, equipment and warranties. Our solar quote checker flags high prices and other red flags, and our guide to choosing a solar company covers the rest.

Can I add hurricane battery backup to solar in Port St. Lucie?
Yes. A battery stores your solar power and keeps chosen circuits running when the FPL grid goes down, which standard solar alone can't do: grid-tied panels shut off in an outage. After a storm, the panels recharge the battery each sunny day until the grid comes back. One 13.5 kWh battery runs about $13,000 installed at recent South Florida prices, with no utility or state rebate.
One battery usually covers essentials; running central air usually takes two or more. Because FPL already credits exported solar at the full rate, a battery's value is backup, not a lower bill. See solar battery backup for hurricanes.
What permits and paperwork does solar need in Port St. Lucie?
- On October 9, 2024, two confirmed tornadoes touched down in St. Lucie County ahead of Hurricane Milton, and the county reported significant damage to multiple homes and structures, including in the City of Port St. Lucie.
- The city's own Building Department, accredited since 2016, issues permits through an online portal. Its post-storm permitting plan expedites reviews for roofs, windows and doors, electrical service restoration and HVAC after a hurricane.
- The city points residents with undergrounding questions to FPL's Storm Secure Underground Program. FPL said in January 2026 that more than 6,000 customers in St. Lucie and Indian River counties had been moved to underground lines.

Only with a battery. Grid-tied panels shut off when the FPL grid goes down, for the safety of line crews; a battery keeps chosen circuits running and the panels recharge it each sunny day.

No. Florida law bars HOAs and deed restrictions from prohibiting solar panels. The association can choose where on the roof they go, as long as the spot faces south or within 45° east or west of due south and doesn't keep them from working well.
