Duke Energy Solar in Florida: Net Metering, Batteries and Energy Savings

By iContracting Solar Team · 2026-09-29

The short answer

Duke Energy Florida customers considering solar should begin with two accurate points. First, Duke is an investor-owned utility covered by Florida's statewide net metering framework. Second, Duke residential bills went down during 2026; they did not rise. Solar should therefore be discussed as a long-term way to manage electricity use and add backup capability, not as a response to a false claim that Duke's 2026 rates increased.

Duke also launched a closed residential battery pilot in Orlando's Hunter's Creek neighborhood. The pilot is useful evidence that batteries can support both peak demand and outage backup, but it is not open for general enrollment.

Confirm that Duke is actually your utility

Utility territories in Central Florida can be split even within the same broader area. Duke serves customers in parts of Winter Garden, Clermont, Apopka, Kissimmee and Lake Mary, as well as the St. Petersburg area. A city name alone does not prove which utility serves a particular address.

Look at the name on the electric bill before applying any utility-specific advice. A neighboring property can have a different provider and therefore a different application process or solar crediting program. If the bill does not say Duke Energy Florida, check with the utility shown there instead.

Duke's 2026 residential bills decreased

The direction of Duke's 2026 bill changes is important. The Florida Public Service Commission approved removal of a storm cost recovery charge associated with hurricanes Debby, Helene and Milton. Starting in March 2026, removing that charge cut a typical residential bill using 1,000 kilowatt-hours by roughly $44 compared with February.

Duke later announced a third reduction for June through September 2026. That change brought a typical 1,000-kilowatt-hour residential bill down about 25 percent compared with January 2026.

These are examples based on the stated 1,000-kilowatt-hour usage level, not a promise about every customer's bill. Actual bills reflect usage and applicable charges. The accurate takeaway is that utility bills can move in both directions over time. Storm recovery charges can be added and later removed. Other approved components can also change.

How to frame solar when rates move both ways

A sound solar decision should not depend on a claim that electric prices only rise. Duke's 2026 reductions demonstrate why. Instead, homeowners can evaluate solar around longer-term bill management, the ability to use electricity produced at the property and the option to pair solar with storage for outages.

That approach is more honest because it separates what a homeowner can influence from what a utility or regulator may change. A homeowner can review consumption, select an appropriately sized system and decide which circuits matter during an outage. No installer can guarantee the future direction of every utility charge.

A proposal should show the electricity usage it used, explain the assumed solar production and identify any assumptions about export credits. It should not turn a temporary charge, a one-month comparison or a generic escalation figure into a guaranteed long-term result.

How Duke net metering works

Duke Energy Florida is one of Florida's investor-owned utilities governed by PSC Rule 25-6.065. Under that framework, systems up to 2 megawatts are eligible, and Tier 1 includes systems of 10 kilowatts or less — the size category that includes many homes.

Exported solar electricity is credited at the retail energy rate. Excess credits carry forward from month to month within the calendar year. At the end of the calendar year, unused credits are paid at the utility's avoided-cost rate. Fixed monthly customer charges still apply.

That year-end treatment is one reason system sizing matters. A design based on the property's actual consumption can aim to make the production useful rather than creating a recurring surplus that remains unused at year-end.

Solar does not automatically provide outage power

A normal grid-tied solar system shuts down when the grid is out. That safety behavior prevents electricity from reaching lines while crews are working. Sunny weather alone does not keep a standard grid-tied home energized.

Backup requires compatible equipment that can isolate the home from the grid. Battery storage can then support selected circuits or a broader backup plan, depending on the design. Our guide to solar during a power outage explains the difference between essential-load and whole-home backup without promising a fixed runtime.

For Florida storm planning, also review solar panels during a hurricane. Solar and storage should be considered alongside roof condition, safe shutdown procedures and post-storm inspection.

Duke's Hunter's Creek battery pilot

In February 2026, Duke announced a Residential Battery Storage Pilot in Orlando's Hunter's Creek neighborhood. Generac battery systems are being used in more than 75 homes during a 10-year study. Duke is studying how residential batteries can support the grid during peak demand and provide backup power during outages.

The pilot is provided at no cost to its participants, but it is closed. Homeowners elsewhere should not assume that they can enroll or receive the same equipment or terms. The correct use of the pilot in a solar discussion is to explain what Duke is studying, not to advertise it as a public incentive.

Read the details in Duke Energy's official Hunter's Creek battery pilot announcement.

What the pilot does and does not prove

The study reflects two distinct battery roles. From the utility perspective, groups of residential batteries may help support peak-demand periods. From the household perspective, a properly configured battery can supply backup during an outage.

The announcement does not make the closed pilot a general Duke program, and it does not establish that one battery configuration is right for every home. Backup needs vary with the circuits a household wants to operate, the equipment's capabilities and electricity use during the outage. A site-specific assessment remains necessary.

It is also important not to confuse battery backup with net metering. Net metering concerns solar exports and bill credits. Backup concerns how the home safely separates from the grid and powers chosen loads. The two can work together, but they solve different problems.

Questions to ask about a Duke solar proposal

Start with a complete electricity-use history, not only the highest bill. Ask how the proposed system size relates to annual usage and what happens to estimated surplus at the end of the calendar year. Confirm which fixed customer charges remain.

Ask the installer to separate three parts of the recommendation: solar production, net metering and backup. If storage is proposed, identify the circuits to be backed up and avoid accepting a generic runtime promise. If the proposal mentions the Hunter's Creek pilot, confirm that it clearly describes the program as closed.

Finally, check the date and comparison behind any statement about Duke bills. An accurate 2026 explanation must acknowledge the storm-charge removal and later reductions. Rates and charges can change in either direction, so check the current bill and Duke's current information before making a purchase decision.

Comparing Duke with other Central Florida utilities

Duke, FPL and TECO share the statewide investor-owned utility framework, while their applications differ. See our TECO solar guide if Tampa Electric appears on the bill. OUC is different because it is municipal; new Orlando systems follow the separate timeline explained in our OUC TruNet Solar guide.

Incentive assumptions also need a current check. The residential 30 percent federal credit ended for systems installed after December 31, 2025. Our Florida solar incentives in 2026 guide explains what remains and why homeowners should consult a tax professional.

The best next step is a proposal built around the correct utility, the property's real usage, roof condition and outage priorities. Use the Central Florida Solar Guide to connect these decisions before choosing equipment.
