FPL net metering allows solar customers to roll over excess credits at the retail rate month-to-month. Under Florida statute (s. 366.91, F.S.), utilities must offer net metering, though recent legislative changes (SB 1024, 2022) modified the structure. Verify current FPL net metering terms at fpl.com/solar.

How it works
How solar savings work in Miami
- Your panels capture Miami's year-round sunshine Miami averages 5.49 peak sun hours per day and enjoys strong solar irradiance year-round — the relatively flat seasonal curve means good production in winter as well as summer. A 6 kW system produces approximately 9,100 kWh per year.
- An inverter converts DC to AC A solar inverter (string or microinverter) converts DC electricity from the panels to the AC power your home uses. Modern inverters achieve 96–99% conversion efficiency.
- You use solar power instead of buying from FPL Every kWh your system produces offsets what you buy from Florida Power & Light at ~$0.133/kWh. A 6 kW system in Miami produces ~9,100 kWh/year — saving approximately $1,211 annually at current FPL rates.
- Excess power flows back to FPL under net metering When your system produces more than your home consumes, excess electricity flows back to FPL. Under FPL's net metering program, this is credited at the retail rate — roughly $0.133/kWh — against your future bills, with monthly carryover and an annual November true-up.
- You claim the 30% federal tax credit In the tax year of installation, claim a 30% Investment Tax Credit on the full installed cost. On a $17,100 system, that's $5,130 off your federal income taxes — reducing the net cost to $11,970.
- Florida's tax exemptions add more value Florida's sales tax exemption (6%) on solar equipment saves roughly $540–$600 upfront. The property tax exemption keeps the added home value from raising your annual property tax bill — saving $150–$240/year depending on your assessed value and Miami-Dade rate.
FAQ
Common solar savings questions for Miami, FL
How much can I save with solar in Miami, FL?
A 6 kW system in Miami produces roughly 9,100 kWh/year and saves approximately $1,211/year at FPL's current rate. After the 30% federal tax credit, the net cost is about $11,970, with an estimated payback period of ~10 years and 25-year net savings of ~$18,305.
How does Florida net metering work for FPL customers?
FPL net metering credits excess solar generation at the full retail rate against your monthly electricity bill. Credits carry forward month-to-month, with an annual settlement in November. Florida SB 1024 (2022) established a multi-year transition to lower export rates for new customers after certain enrollment thresholds — check current FPL interconnection terms at fpl.com/solar before installing.
Does Florida have a state solar tax credit?
Florida does not have a state income tax credit for solar. However, Florida offers two meaningful state incentives: a sales tax exemption (6% waived on solar equipment) and a property tax exemption (the value solar adds to your home is excluded from property tax assessment). Together these save several hundred dollars upfront and annually.
How much does a solar system cost in Miami?
A 6 kW system in Miami costs approximately $17,100 before incentives ($2.85/watt, per Lawrence Berkeley Lab 2024 Florida data). After the 30% federal Investment Tax Credit ($5,130), the net cost is ~$11,970. Florida's sales tax exemption on equipment saves an additional $540–$600 at purchase.
Is Miami a good location for solar?
Yes. Miami averages 5.49 peak sun hours per day with relatively consistent production year-round — summer humidity has modest impact on panel output. Miami's high electricity bills ($140–$200/month for many households) also mean more savings per kWh generated compared to lower-cost markets.
How many solar panels does a Miami home need?
A typical Miami home using 1,000–1,200 kWh/month needs a 6–8 kW system — roughly 15–21 panels at 380–400 W each. Miami's high air conditioning load in summer makes system sizing especially important. Use the calculator above with your monthly bill to estimate.
