Does Duke Energy Florida pay for excess solar power?

Excess power is banked as kWh at the full retail rate and drawn down in later months. The bank resets in December, and anything left is paid out at about 3.00¢ per kWh.

How big a solar system can I net-meter with Duke Energy Florida?

Systems up to 2000 kW AC qualify for net metering.

Does Duke Energy Florida have a demand charge?

Duke Energy Florida has no residential demand charge, so every kWh solar offsets saves the full energy rate.

What would solar cost and save for a typical Duke Energy Florida home?

For a electrically heated home using about 1100 kWh a month, a net-zero system is about 8.8 kW, costs roughly $19,135 to $23,387 installed, saves $1,823 to $2,085 in the first year, and pays back in 8.5 to 11.4 years at 2.7% a year rate growth. Your address gives a real figure in about a minute.

What federal incentives apply in 2026?

Florida exempts solar equipment from sales tax and keeps the value it adds off your property-tax bill, and both are already in these figures. Business-owned systems, including rental property, qualify for the 30% federal investment credit (Section 48E) and bonus depreciation when placed in service by the end of 2027; tax-exempt owners receive the 30% as cash. Not tax advice.

Where do these numbers come from?

The rate figures are read from Duke Energy Florida's own published schedule and net-metering policy (linked under Sources), last checked November 1, 2026. The worked example runs the same engine as the estimator, using a production reference for Spring Hill and Florida installed-cost data. If you spot an error, email us and we will correct it.
