2 Your usage and system
Find this on a recent utility bill, usually labeled kWh used.
Use your quoted or planned system size. Panel count times panel wattage divided by 1,000 gives a rough figure.
Solar production swings seasonally; pick a specific month type to see how your bill shifts.
Most utilities charge a flat customer or connection fee regardless of usage.
3 Your location and rate
Defaulted to Florida's statewide average. Adjust if you know your local figure.
Defaulted to Florida's current average residential rate. Your utility's actual rate may differ.
Florida typically credits exports around 100% of retail for both new and existing systems, since the proposed step-down toward avoided cost was vetoed and never took effect.
Some utilities charge progressively higher per-kWh rates as monthly usage climbs into higher tiers.
Accounts for inverter loss, wiring loss, dust, and temperature derate combined.
Informational only. A monthly cycle means unused export credit does not carry to the next bill; annual and rolling cycles do.

How it works

Three steps to your Florida solar bill estimate

Step 1

Enter your usage, system size, and season

Pull your monthly kWh from a recent bill and enter your planned or quoted system size in kW. If you only know your panel count, multiply it by each panel's wattage and divide by 1,000 to get a kW figure first. Select a season to model a specific month rather than only an annual average.

Step 2

Confirm your rate, tier, and export credit

Florida's typical residential rate and export credit level are filled in by default. Swap in your utility's actual tariff numbers, tier bracket, and fixed monthly fee if you have a recent bill or interconnection agreement showing them.

Step 3

Compare the result to a full retail scenario

Run the net billing vs net metering comparison tool to see exactly how much Florida's current export credit rate costs you compared to full 1:1 retail crediting.

How net metering works in Florida

Florida still runs full retail net metering today

Florida's four investor-owned utilities, Florida Power & Light, Duke Energy Florida, Tampa Electric, and Florida Public Utilities, along with several electric cooperatives, currently credit exported solar power at the full retail rate, kilowatt-hour for kilowatt-hour, under rules the Florida Public Service Commission established back in 2008. A 2022 bill that would have phased this down toward avoided cost by 2029 passed the legislature but was vetoed by the governor, so full retail crediting remains the operative rule statewide.

The grandfathering date that would have applied never took effect

Senate Bill 1024 was the Senate companion to HB 741, not a separate law, and it died in the same April 2022 veto rather than being enacted on its own. Its proposed 20-year grandfathering for systems interconnected before January 2024, and a step-down schedule for anything after, never took effect, so there's no statewide cutoff date currently in force. Florida's tax credit and rebate estimator is still worth checking regardless, since full retail net metering currently applies to new and existing systems alike.

Excess annual credits are handled differently by utility

Within a billing cycle, credits roll forward month to month at full retail value, letting you bank sunny-season surplus against higher summer cooling loads. At the end of each annual cycle, though, treatment of any leftover balance varies: FPL and Duke Energy Florida generally settle unused annual credits at the utility's avoided-cost rate rather than retail. For the official wording, see the 2022 bill that would have phased this down.

Why Florida remains one of the strongest net metering states

Combining full retail crediting with Florida's high sun-hour count and a permanent 100% property tax exemption on the value solar adds to a home makes Florida's overall solar economics among the most favorable nationally, even once you account for how the annual true-up settles any leftover credits.

Interconnection and the off-grid comparison

Interconnecting still requires your utility's standard application and inspection process regardless of your specific crediting terms; the grid interconnection cost estimator covers what that typically costs. And with full retail crediting in place, the case for going fully off-grid in Florida is weaker than in states with reduced export rates; the grid tie vs off grid comparison tool shows the actual cost gap.

Questions

Frequently asked

Investor-owned utilities currently credit exports at full retail rate, about 15.2 cents/kWh, with no scheduled phase-down in effect for new or existing systems. A 2022 bill that would have phased credits down over time and locked in a grandfathering schedule was vetoed by the governor and never took effect.

The average residential rate in Florida is about 15.2 cents per kWh. Investor-owned utilities currently credit exports at that full retail rate for new and existing systems alike, with no statewide phase-down schedule currently in effect.

The legislature passed a bill in 2022, HB 741, with its Senate companion SB 1024, that would have phased down full retail crediting toward avoided cost by 2029 and set a 20-year grandfathering schedule, but the governor vetoed it and neither bill took effect. Florida's investor-owned utilities currently still credit solar exports at the full retail rate, with no statewide phase-down or grandfathering cutoff in force.

It depends on your utility. Within a billing cycle, credits carry forward month to month at full retail value. At the annual settlement, FPL and Duke Energy Florida generally pay out any remaining balance at the utility's avoided-cost rate rather than retail, so check your specific provider's exact annual terms.
