Medición Neta frente a Facturación Neta en Florida: Lo que necesitas saber
Net Metering vs Net Billing Florida is one of the first topics to understand before you sign a solar contract or take over an existing system. Sunprise installs commercial solar for Florida businesses. We do not currently offer residential solar installation. Residential guidance in this article is educational only.
Net metering lets your renewable generation offset the electricity you draw from the grid using kWh credits on your bill. Net billing (sometimes called buy-all, sell-all or distributed generation) treats grid imports and solar exports as separate transactions. You buy power at retail and sell excess at a lower export rate, often based on avoided cost or fuel cost.
Florida investor-owned utilities and most cooperatives follow PSC Rule 25-6.065 net metering today. Some municipal utilities use export rates closer to net billing. This guide explains how each model affects your bill, what Florida law requires in June 2026, and where to verify rules with your serving utility. Commercial owners evaluating on-site generation can also read our 2026 guide for solar business owners y request a Commercial Solar analysis.
FLORIDA SOLAR POLICY
Net Metering vs Net Billing Florida: Core Definitions
The Florida PSC defines net metering as a metering and billing method where customer-owned renewable generation offsets the customer electricity consumption on-site (Rule 25-6.065(2)(c)). A bidirectional meter records energy from the utility and energy sent to the grid. During each billing cycle, exported kWh reduces billed kWh from the utility. Unused kWh credits roll to the next month for up to twelve months.
Net billing structures vary by utility but share a common pattern. You purchase all energy you need from the grid at your retail rate schedule. Energy your system exports is credited at a separate, usually lower rate. That export rate may be labeled avoided cost, fuel rate, or wholesale proxy. Customer charges, minimum bills, and demand charges often still apply.
California NEM 3.0 is a well-known net billing example in national policy discussions. Florida IOUs still operate under the 2008 PSC net metering framework as of June 2026. Municipal programs such as JEA Distributed Generation are closer to net billing for new systems installed after March 31, 2018. Your zip code and utility name determine which rules apply, not the marketing language on a sales brochure.
What Florida Law Requires for Net Metering in 2026
Rule 25-6.065 requires each investor-owned utility to offer net metering to interconnected customer-owned renewable generation up to 2 MW gross power rating. Key billing provisions include:
Monthly meter reads on the same cycle as the customer rate schedule.
Excess generation in a billing cycle credited to the next month energy consumption.
Credits accumulate up to twelve months.
At calendar year end, unused credits paid at the utility average annual COG-1 as-available energy tariff rate.
When a customer leaves the system, remaining credits paid at the COG-1 rate.
Customer charges and demand charges still apply for maximum measured demand.
House Bill 741 (2022) would have phased down retail credits and allowed new fixed charges on solar customers. Governor Ron DeSantis vetoed CS/CS/HB 741 on April 27, 2022. The veto transmittal letter cited inflation and cost burdens on ratepayers. That bill did not become law. Legislative proposals may appear in future sessions. Confirm current statute and tariff language before you rely on any single quote from a salesperson.
No statewide law guarantees net metering terms forever. The PSC can open rulemaking, and the Legislature can introduce new bills. Reading official utility tariffs and FSEC rule text is more reliable than social media summaries.
How Net Metering Works on Your Florida Bill
Solar panels produce direct current (DC). An inverter converts DC to alternating current (AC) for your building. Power your equipment uses on-site never passes through the utility meter. Only surplus AC flows to the grid.
On FPL territory, excess monthly generation adds to your kWh reserve (energy bank). The reserve offsets future monthly consumption. FPL states customers do not receive cash for routine monthly exports; they receive kWh credits. If unused kWh remain when the December meter read occurs, FPL applies a credit based on average annual cost of electricity generation per its tariff and COG-1 rate schedule (FPL net metering FAQ).
FPL also charges a $30 minimum base bill for net metering customers. That minimum covers fixed distribution costs even when kWh reserves reduce energy charges. Other IOUs include similar customer charge structures in their tariffs.
Your inverter display shows total production. Your utility bill shows grid imports, exports, and credits applied. Those numbers will not match inverter totals because on-site self-consumption is invisible to the utility meter.
How Net Billing Differs From Net Metering in Florida
Under net billing, export value is separated from retail import value. You may pay full retail for every kWh drawn from the grid while receiving a lower credit for each exported kWh. Monthly true-up can leave smaller bill savings than full kWh banking when your export rate is well below retail.
JEA describes its program as Distributed Generation rather than retail net metering for most new systems. Customers buy electricity from JEA at retail when solar output is insufficient. Exports receive a credit at JEA fuel rate (avoidable fuel cost), which JEA publishes monthly (JEA DG policy). Systems interconnected before March 31, 2018 may qualify for grandfathered net metering for twenty years attached to the system address.
Battery storage changes the math on any tariff. Stored solar can supply your building instead of exporting during low-value periods. Batteries add cost, maintenance, and interconnection rules. Read our post on generators vs solar batteries in Florida for backup context. Sunprise can discuss commercial battery options when they align with facility goals.
Net Metering vs Net Billing Florida by Utility
Programs below reflect official utility and PSC sources as of June 2026. Tariffs change. Confirm details on your current bill and utility website before signing contracts.
Florida Power & Light (FPL) and Gulf Power
FPL serves much of South Florida, the Treasure Coast, and portions of Central Florida. Gulf Power and FPL Northwest follow FPL net metering programs. Application is required before installation. Tier 1 covers up to 10 kW AC gross rating, Tier 2 up to 100 kW, Tier 3 up to 2 MW. Tier 2 and Tier 3 require liability insurance and may require manual disconnect switches and three-phase service at 50 kW and above. Program overview: FPL net metering.
Duke Energy Florida
Duke Energy Florida follows FPSC Rule 25-6.065 for interconnected renewable systems. Interconnection applications and tier processes are on Duke Energy generate-your-own pages. Select Florida when the site prompts for location. Export credit mechanics follow the IOU net metering rider in Duke Florida tariffs filed with the PSC.
Tampa Electric (TECO)
TECO serves Hillsborough County and parts of Polk and Pasco. Net metering for customer-owned renewable generation follows PSC rule requirements. Confirm interconnection forms and insurance thresholds on tampaelectric.com before construction starts.
Withlacoochee River Electric Cooperative (WREC)
WREC members in Citrus, Hernando, Lake, Levy, Marion, Pasco, and Sumter counties submit PDF application packages to rgs@wrec.net. WREC installs a net meter after approval. If annual generation exceeds annual use, WREC purchases excess at Seminole Electric Cooperative avoided cost per WREC solar energy page. WREC does not sell or install PV systems.
Lee County Electric Cooperative (LCEC)
LCEC net metering rider defines net kWh as delivered kWh minus returned kWh each billing cycle. Excess monthly kWh carries forward through the calendar year, then pays at LCEC calculated avoided purchase power cost. Tier 1 interconnection fee is $35; Tier 2 up to $1,000; Tier 3 $1,000 per 2026 tariff. Email LCECNetMetering@lcec.net. Education page: LCEC solar.
JEA (Jacksonville)
JEA is the clearest large Florida example of export crediting below full retail net metering for new systems. Distributed Generation credits exports at the fuel rate. Grandfathered net metering applies to qualifying systems installed by March 31, 2018. Apply through JEA PowerClerk portal. Policy PDF: JEA distributed generation. Contact distgen@jea.com for technical questions.
Orlando Utilities Commission, Kissimmee, and Other Municipals
Orlando Utilities Commission (OUC), Kissimmee Utility Authority (KUA), Homestead Energy Services, Keys Energy Services, and smaller municipals set their own distributed generation tariffs. They are not automatically bound by Rule 25-6.065 the same way IOUs are. Download the current tariff sheet from your utility account portal or contact customer service for export rate tables before you model payback.
System Size Tiers, Fees, and Insurance
Florida PSC tiers use gross AC power rating. Inverter systems multiply total DC nameplate by 0.85 to determine tier placement.
Tier 1: 10 kW or less. IOUs shall not charge extra interconnection application fees beyond standard customer fees.
Tier 2: Above 10 kW through 100 kW. Minimum $1 million general liability insurance typically required.
Tier 3: Above 100 kW through 2 MW for IOUs (LCEC tariff lists Tier 3 up to 1 MW). $2 million liability insurance and possible interconnection study charges.
Equipment must meet UL 1741 and IEEE 1547 standards. AHJ inspection is required before parallel operation. Tier 2 and Tier 3 systems often need visible load-break disconnect switches adjacent to the utility meter.
Residential Readers: Steps Before Going Solar
Sunprise does not install residential rooftop solar. If you are researching for your home, use this checklist with official sources:
Identify your serving utility and read its current net metering or DG tariff.
Start the utility interconnection application before installation where required (FPL mandates pre-approval).
Collect three written quotes from licensed Florida contractors verified on DBPR.
Model payback using your actual usage, not a salesperson production sheet alone.
Review DOE smart shopping tips for solar and our solar sales misinformation guide.
Moving into a home with existing panels? You must sign a new interconnection agreement with the utility to activate credits. FPL and Duke publish move-in workflows for new account holders.
Commercial Owners: Demand Charges and Net Metering vs Net Billing Florida
Commercial rate schedules often include demand charges based on your highest fifteen-minute or thirty-minute peak each billing period. Rule 25-6.065(8)(h) states IOUs continue to bill demand charges even when solar offsets energy kWh. Net metering does not eliminate demand charges by default. Peak shaving may require load management, batteries, or tariff selection review with your utility account manager.
Commercial facilities in Tampa, Orlando, and Miami metro areas should map interval demand against solar production curves. A warehouse with evening shifts may export midday solar while still setting peak demand after sunset. Results vary by tariff and operations.
Sunprise engineers commercial systems with these constraints in mind. See our Commercial Solar Florida guide y Beverly Hills commercial solar example. Request a Commercial Solar analysis when you want a business-specific review.
Net Metering vs Net Billing Florida FAQ
House Bill 741, which would have phased down retail net metering credits, was vetoed by Governor DeSantis on April 27, 2022. As of June 2026, investor-owned utilities still follow PSC Rule 25-6.065 net metering. Future legislation or PSC rulemaking could change terms. Verify current law and your utility tariff before signing a contract.
FPL net metering customers receive kWh credits for excess generation rather than cash during the year. Unused credits accumulate in your kWh reserve (energy bank) and offset future monthly use. FPL applies a year-end credit for unused kWh at its average annual generation cost per net metering FAQs.
Most FPL customers receive full kWh banking under Rule 25-6.065. JEA uses Distributed Generation for new systems after March 31, 2018, crediting exports at the fuel rate rather than full retail net metering. Grandfathered JEA net metering may still apply to older systems. Read JEA policy for your address.
Under Rule 25-6.065, investor-owned utilities pay customers for unused energy credits at the end of the calendar year at the average annual COG-1 as-available energy tariff rate. Cooperatives such as LCEC and WREC use avoided cost language in their tariffs. Exact amounts vary by utility and year.
Apply for net metering or distributed generation with your utility and sign a new interconnection agreement in your name. FPL and Duke publish move-in workflows. Existing equipment usually does not need redesign if nothing changed, but utility approval is required before credits apply.
Batteries can store solar output for later use instead of exporting at lower credit rates. They add equipment cost, maintenance, and interconnection requirements. On JEA fuel-rate exports or any low export credit tariff, batteries may improve self-consumption economics. Results vary by usage and tariff.
