Meter aggregation, the practice of combining bill credits across multiple electric accounts under one solar system, is not a standard option for typical Florida homeowners or businesses under investor-owned utility net metering programs. The main exception is public educational customers, who gained a statutory right to aggregate meters within a school district under HB 1611. If you own multiple meters, your next move is checking your utility tariff and running a feasibility study before assuming aggregation applies to you.
TL;DR:
- Aggregation for multiple meters is generally unavailable for residential and most commercial customers under Florida net metering rules, except for public educational districts.
- Florida’s point-of-delivery rule means credits are awarded only at the physical meter where solar power enters the system, limiting the practicality of aggregation.
- Systems larger than about 115% of a property’s historical consumption typically underperform due to payout rates at the year-end true-up rate, especially without aggregation rights.
- For multi-meter properties, conducting a detailed feasibility study and utility tariff review is essential to determine the best system size and design, including battery options.
- The state’s conservative stance and variation in municipal or cooperative policies mean property owners should verify each utility’s specific policies before planning substantial solar projects.
What Is Meter Aggregation Solar in Florida, and Why Does It Matter?
Meter aggregation, sometimes called virtual net metering, lets a solar system credit its output across multiple electric meters or accounts instead of offsetting only the meter it is physically connected to. Instead of a one-to-one relationship between a solar array and the meter it feeds, aggregation splits the generation credits across several accounts based on a pre-set allocation formula.
The concept exists because plenty of Florida properties do not fit the single-meter model that most net metering rules assume. Think of a citrus farm with separate meters for irrigation pumps, packing sheds, and an office building. Or a school district running a dozen campuses on one utility. Or a multi-tenant retail plaza where each unit has its own account.
For these owners, on-site net metering (where solar output offsets consumption at the exact meter it is tied to) creates a mismatch. A single large rooftop or ground-mount array might generate far more power than one building needs while a neighboring meter on the same property draws heavily from the grid. Aggregation, where it is permitted, solves that mismatch by letting excess credits flow to a sister account.
The practical difference comes down to flexibility:
- On-site net metering: Solar output offsets only the consumption at that specific meter; excess rolls into that same meter’s monthly credit.
- Aggregated (virtual) net metering: Credits generated at one meter get allocated across multiple accounts, based on a formula filed with the utility.
- Result for owners: Aggregation can dramatically improve the economics of a single, well-sited system versus building several smaller, redundant ones.
That flexibility is exactly why Florida limits it so tightly, which the next section explains.
How Does Net Metering Work Under Florida Rule 25-6.065?
Florida’s net metering framework runs through Rule 25-6.065, which defines net metering as a methodology allowing customer-owned renewable generation to offset consumption at the customer’s own point of delivery. That phrase, “point of delivery,” is the crux of the whole aggregation question. The rule ties crediting to the physical meter where power enters the customer’s system, not to a customer’s broader portfolio of accounts.
Under the rule, investor-owned utilities must enable net metering, install metering equipment at that point of delivery, and credit excess generation monthly. Credits that exceed a given month’s usage roll forward for up to 12 months. Whatever is left unused at the annual true-up gets paid out, not at the retail rate you pay for power, but at the utility’s as-available energy rate, commonly referenced as the COG-1 tariff.
Rule 25-6.065 requires monthly crediting, allows a 12-month rollover of unused credits, and mandates a year-end cash-out at the as-available (COG-1) rate rather than full retail value. That single mechanic shapes almost every financial model a Florida solar consultant builds for a client with excess production.
The 2 MW threshold. Systems up to a certain size qualify for expedited interconnection under the rule’s standardized agreement process, which matters for larger commercial and institutional projects that might otherwise face lengthy utility studies. The customer typically owns and installs the generation and metering equipment on their side of the interconnection point, and any renewable energy certificates (RECs) associated with the system generally stay with the customer unless otherwise negotiated with the utility.
For billing purposes, this means your solar production shows up as a credit line on the same monthly bill cycle you already know, but demand charges (for commercial accounts on demand-based rate schedules) are calculated separately from the energy credit and are not typically offset by net metering credits in the same way.
Who Qualifies for Solar Meter Aggregation in Florida?
Ordinary residential and commercial customers cannot rely on a statewide right to aggregate meters under standard investor-owned utility net metering tariffs. Florida rule tied credits to the point of delivery, and that design was intentional. It keeps grid accounting simple for the millions of single-meter households and small businesses the system was built around.
The specific exception is public educational customers. HB 1611, passed in 2021, requires utilities to offer meter aggregation to public educational customers, allowing a single school district to allocate net-metering bill credits across multiple accounts served by the same utility. That is a meaningful carve-out for districts with dozens of campuses on one utility footprint, but it comes with real boundaries:
- Aggregation applies only within a single school district and only across accounts served by the same utility.
- Allocation typically covers a defined range of accounts limited to a certain number specified by the utility tariffs in many district filings, not an unlimited portfolio.
- Annual allocated kilowatt-hour caps apply, meaning a district cannot simply funnel unlimited credits from one mega-system to every campus.
- Utilities were required to adopt tariff language implementing this allowance, so the exact mechanics vary slightly by provider.
If you run a municipal utility or a rural electric cooperative account rather than an investor-owned utility account, the rules can differ entirely. Municipal and co-op providers set their own net metering and interconnection policies, and some have experimented with aggregation-style pilots that investor-owned utilities have not. That variability is precisely why checking your specific utility tariff before assuming any policy applies to your property is worth the hour it takes.
What Should You Do If Aggregation Isn’t Available to You?
If you own several meters and standard aggregation is off the table, you still have real options. Here is the order most Florida solar consultants work through with multi-meter clients.
- Identify your utility type first. Investor-owned utilities like FPL, Duke Energy, and TECO follow Rule 25-6.065 directly. Municipal utilities and co-ops set their own tariffs, so pull the actual document rather than assuming statewide rules apply.
- Call your utility’s interconnection desk. Ask specifically whether any aggregation, allocation, or shared-solar pilot program exists for your customer class. Get the answer in writing.
- Map every meter on the property. List account numbers, physical locations, historical 12-month usage, and rate schedules (including any demand charges) for each one.
- Run a feasibility study. A proper study estimates system size against the 115% consumption cap, models monthly credit flow and year-end settlement at the as-available rate, and tests whether one larger system or several smaller ones produces the better return.
- Weigh alternatives if aggregation truly is not an option. Community or shared solar subscriptions, behind-the-meter battery storage to shift usage rather than export it, and separately sized systems for each meter are all viable paths in Florida’s current market.
Pro Tip: Before you size anything, ask your utility account representative for a full year of interval usage data by meter. Most owners underestimate how unevenly their consumption is split across accounts, and that imbalance is exactly what determines whether one shared system or several separate ones makes financial sense.
Third-party allocation arrangements and virtual power purchase agreements exist elsewhere in the country, but Florida’s investor-owned utility tariffs do not generally support them outside the public-education exception. Treat any vendor who claims otherwise with real skepticism, and verify against your actual tariff.
How Does the 115% Sizing Rule Affect Your Solar Investment?
Florida solar systems are generally capped at around 115% of a customer’s historical annual consumption, a limit designers use to keep systems sized to the meter’s real usage pattern rather than built purely for export.
That cap shapes every financial model. Here is why it matters more than most owners expect:
- Monthly credits roll for up to 12 months, so a big production month in March can offset a high-usage month in July without penalty, as long as the credit gets used within the annual cycle.
- Unused credits at year-end are paid at the as-available (COG-1) rate, not your retail rate. On many Florida tariffs, that gap can mean a system exporting large surpluses recovers only a fraction of what those kilowatt-hours would have been worth as an on-site offset.
- Design tactics that protect value: size the system to match actual load rather than maximum roof space, prioritize offsetting the meter with the highest retail rate, and consider pairing with battery storage to shift usage patterns rather than exporting excess to the grid.
For multi-meter properties without aggregation rights, this cap gets applied meter by meter, which is exactly why a single oversized system rarely performs as well on paper as several properly sized ones, or one system carefully matched to the highest-value meter.
When Should You Hire a Florida Solar Consultant for a Feasibility Study?
Multi-meter properties, school districts, and any commercial account juggling more than one utility tariff are precisely the cases where an independent feasibility study earns its cost back many times over. A rushed or generic proposal from an installer rarely accounts for demand charges, tariff-specific COG-1 rates, or the sizing math across several accounts at once.
A proper feasibility study should deliver:
- A tariff and interconnection review specific to your utility and rate schedule.
- Meter-by-meter and account-by-account mapping of the property.
- An ROI model that factors in the federal investment tax credit, state incentives, and realistic year-end settlement value.
- Design alternatives, including battery storage, a shared facility system, or separately sized systems per meter.
- A project management plan that carries the analysis through to construction.
Complex cases justify this most: districts spanning multiple utility territories, properties split between municipal and investor-owned service, or any account with meaningful demand charges layered on top of energy costs. Solar Energy Management has worked through this exact analysis for Florida property owners navigating multi-meter decisions.
What Are the Real Limits of Florida’s Aggregation Rules?
Florida’s approach to aggregation is narrow by design, and that creates practical friction for owners who assume the rules work like other states. The point-of-delivery structure in Rule 25-6.065 means most private customers simply have no statutory path to combine meters, regardless of how logical it would be for their property.
The public-education exception under HB 1611, while real, is also administratively demanding. Districts must confirm every account sits within the same utility’s territory and the same district boundary, then track allocation against annual kilowatt-hour caps that utilities set through their own tariff filings. Two districts on different utilities cannot combine credits, no matter how close their campuses sit geographically.
Municipal utilities and cooperatives add another layer of inconsistency. Because they are not bound by the same statewide rule in the same way investor-owned utilities are, a policy that works in one city’s utility territory may not exist a few miles away under a different provider. That patchwork means a generalized answer to “does aggregation work in Florida” is nearly impossible to give without naming the specific utility involved.
There is also a value gap baked into the system: even where aggregation or rollover credits apply, year-end payouts at the as-available rate mean any surplus beyond what gets used within 12 months loses significant value compared to on-site offset. That structural limitation pushes most feasibility work toward “size for your load” rather than “size for maximum export,” regardless of how the credits get allocated.
How Does Florida’s Virtual Net Metering Compare to Other States?
Florida’s aggregation posture sits on the more conservative end nationally. States with dedicated community solar or virtual net metering statutes, tracked through resources like DSIRE’s program database, often let a broader range of residential and commercial subscribers receive allocated bill credits from an off-site or shared array, not just public educational customers.
Some states also allow third-party ownership structures or subscription-based shared solar that spreads credits across dozens or hundreds of subscribers on the same utility system. Florida has resisted that model at the investor-owned utility level, keeping the point-of-delivery structure central to its net metering rule and reserving legislative carve-outs for narrow, defined cases.
The National Conference of State Legislatures’ review of state net metering policies confirms this variability is the norm rather than the exception nationwide: aggregation rights depend heavily on individual state statutes and utility tariffs rather than any federal standard. For Florida owners, the practical takeaway is that comparing your options to what a neighbor in another state has access to will usually lead you astray. Best practice here means working from Florida’s specific rule language and your own utility’s tariff, not a generic multi-state assumption.
A Consultant’s View: Three Lessons From Florida Multi-Meter Projects
Three patterns show up again and again on Florida properties with multiple meters. First, always validate the actual utility tariff before sizing anything. Assumptions based on a neighboring utility’s rules, or on what worked in another state, lead to expensive redesigns. Second, design to on-site load rather than betting on year-end cash-outs. The as-available rate is real money left on the table if your business case leans on it. Third, if you are a school district or other public customer, get the allocation limits and tariff language from your utility in writing before you finalize any system size. Verbal assurances about aggregation caps have a way of changing once the paperwork gets filed.
How Solar Energy Management Helps You Navigate Meter Aggregation
An independent alternative exists to relying on an installer’s sales proposal for multi-meter properties in Florida. Where a typical installer sizes one system for one meter and moves on, Solar Energy Management maps every account on your property, checks the actual utility tariff governing each one, and builds a financial model around Florida’s real settlement mechanics rather than a generic national assumption.
For property owners with more than one meter, a school district exploring the HB 1611 allocation, or a commercial account weighing separate systems against one larger array, that distinction changes the outcome of the entire project. Services include solar feasibility studies, ROI and financial modeling, tariff and interconnection review, and battery or microgrid planning for properties where on-site load management matters more than export credits. Homeowners can start with residential solar consulting, while businesses, farms, and districts with multiple accounts should look at commercial solar consulting and system design. Reach out to request a site-specific assessment before committing to a system size or a single-meter proposal that ignores the rest of your property.

FAQ
Is Net Metering Worth It in Florida?
For most single-meter homes and businesses, yes: net metering under Rule 25-6.065 lets you offset your own consumption and roll unused credits forward for up to 12 months. The value drops for owners who habitually overproduce, since unused year-end credits pay out at the as-available COG-1 rate rather than retail.
What Is the 115% Rule for Solar Panels in Florida?
Florida generally caps net-metered system sizing at around 115% of a customer’s historical annual electricity consumption, which keeps systems matched to actual usage rather than built purely to maximize export.
Who Is a Reputable Solar Resource for Florida Property Owners?
Look for a provider with specific Florida experience in tariff analysis and interconnection rules rather than a generic national installer. Solar Energy Management focuses specifically on Florida feasibility studies, financial modeling, and system design for both residential and commercial properties.
Is Net Metering Going Away in Florida?
Florida’s current net metering framework under Rule 25-6.065 remains in effect, though utility tariffs and program details can change over time. Checking your specific utility’s current tariff, rather than relying on general assumptions, is the only reliable way to confirm current terms.
Can a Homeowner With Two Meters Aggregate Solar Credits in Florida?
Generally, no. Standard investor-owned utility net metering tariffs tie credits to the point of delivery for each meter individually, and the aggregation exception under HB 1611 applies specifically to public educational customers, not private residential accounts.
