Duke Energy Florida: how it credits the solar power you send to the grid
Full retail net metering under Florida's rule for investor-owned utilities: exported power offsets bought power kWh for kWh, and leftover credit carries forward until the yearly settlement.
Checked November 12, 2026. Utilities change these rules; check the current tariff before you sign.
How it works
Exported power earns the full retail price, kWh for kWh.
Duke Energy Florida, serving St. Petersburg, Orlando's suburbs and much of north and central Florida, follows the same state rule as FPL.
Credit left at the end of the year is paid at a much lower rate, so oversizing doesn't pay.
Fixed monthly charges can't be offset by solar credits.
Ask Duke for the rate it pays on credit left at year end before sizing the system above your use.
What it means for a typical Florida home
With full credit, a typical 8 kW system in Florida (about $20,560 at the 2026 median price) pays for itself in about 11 years and saves about $33,433 over 25 years after its price, paid in cash with no federal credit. It doesn't matter much whether you use the power as it's made or send it out, so a battery adds backup, not savings. Payback by system size in Florida.
Also in Florida: Florida Power & Light (FPL) (full retail credit), Tampa Electric (TECO) (full retail credit).
