Utility rate

Duke Energy Florida / OUC electricity rate

$0.118/kWh residential

Utility: Duke Energy Florida / OUC
Residential rate: $0.118/kWh (blended)

Duke Energy Florida serves the majority of the Orlando metro area. OUC (Orlando Utilities Commission) serves central Orlando and parts of Orange County at a different rate schedule. Both utilities offer residential solar net metering under Florida’s net metering statute (F.S. 366.91), which requires utilities to credit excess generation at the full retail rate. Florida has been subject to ongoing policy discussions about future net metering reforms, so homeowners should confirm current interconnection and export credit terms directly with their utility before committing to a system size.

How it works

How solar savings work in Orlando

Orlando gets consistent year-round sun NREL PVWatts modeling for Orlando shows about 5.32 peak sun hours per day. An 8 kW system produces roughly 11,867 kWh per year, with June–September being the best months and December–January the weakest.
Summer production and AC load align well Orlando’s peak solar months overlap with peak cooling season. This means a larger portion of solar output directly offsets the highest-cost electricity the home consumes, improving the economics versus markets where solar peaks and load peaks don’t match.
Duke Energy Florida / OUC net metering credits excess at retail Under Florida law (F.S. 366.91), excess solar production flows back to the grid at the full retail rate. This makes self-consumption AND modest export both valuable. Florida net metering policy has been subject to ongoing legislative debate, so confirm current terms before sizing for export.
Florida’s state tax incentives stack well with the federal ITC Florida exempts residential solar equipment from both state sales tax and property tax assessment. Combined with the 30% federal ITC on a $22,560 system ($6,768 credit), total upfront incentives are among the better stacking options in the Southeast.
Net system cost after ITC is about $15,792 On a modeled $22,560 installed cost, the 30% federal ITC reduces net cost to $15,792. The Florida sales tax exemption saves roughly $1,350 on equipment, and no property tax is added for the system’s value.
Payback is moderate; long-run value is solid At a modeled $0.118/kWh effective rate and $1,400 first-year savings, payback is about 11.3 years. Over 25 years the system is modeled to save roughly $34,100 net of cost, with additional upside from rate escalation and the Florida net metering credit.

FAQ

Common solar savings questions for Orlando, FL

How much can I save with solar in Orlando, FL?

An 8 kW Orlando system is modeled at about 11,867 kWh/year. At a Duke Energy Florida effective rate of roughly $0.118/kWh, first-year savings are around $1,400 and simple payback is about 11.3 years after the federal tax credit.

Does Florida have good solar incentives?

Yes, Florida’s incentive stack is solid for a Sun Belt state. The 30% federal ITC applies universally, and Florida adds a full property tax exemption for residential solar systems and a sales tax exemption on solar equipment. Net metering at the retail rate (under F.S. 366.91) further improves economics.

What is Florida’s property tax exemption for solar?

Florida Statute 196.175 exempts the added assessed value from a residential renewable energy system from property tax. Solar panels increase your home’s market value, but that increase is not counted in your tax assessment, so your property tax bill stays flat.

Does the Florida solar sales tax exemption apply in Orlando?

Yes. Florida Statute 212.08(7)(hh) exempts solar energy systems and components from the 6% Florida state sales tax. This exemption applies statewide, including in Orange County and the City of Orlando.

What is the difference between Duke Energy Florida and OUC for solar?

Duke Energy Florida is an investor-owned utility serving much of the greater Orlando area. OUC (Orlando Utilities Commission) is a municipal utility serving central Orlando and parts of Orange County. Both offer net metering programs, but the rate schedules and specific program terms differ. Confirm which utility serves your address before comparing rates.

How many solar panels does an Orlando home need?

Most Orlando homes land in the 6–10 kW range depending on annual consumption. Because summer cooling loads are high and solar production peaks in summer, systems can be sized somewhat larger than average without stranding production. Confirm current net metering terms with your utility before sizing for significant export.

Do I need a permit for solar in Orlando?

Yes. Rooftop solar requires a City of Orlando or Orange County building permit plus utility interconnection approval. If you are also building a deck, review the Orlando deck permit page so both projects stay coordinated.
