FPL Net Metering Florida: Interconnection Guidelines and Tiers (August 2026)

Key Takeaways

• Your renewable system must be estimated to produce less than 115% of your annual kWh consumption for FPL net metering.
• Systems exceeding 90% of your existing service capacity may incur additional expense.
• FPL defines three tiers: Tier 1 (up to 10 kW AC), Tier 2 (>10 kW up to 100 kW AC), and Tier 3 (>100 kW up to 2,000 kW AC).
• Battery storage cannot export power from the battery to the grid under FPL net metering at this time.

What are FPL's Net Metering Guidelines in Florida?

Florida Power & Light (FPL) net metering allows customers to offset all or part of their energy use at their metered service account with renewable generation. To participate, your system must adhere to specific guidelines established by FPL (August 2026).

All interconnection applications must be approved prior to installation and operation of the renewable energy system (August 2026). FPL requires that customer-owned renewable generation include a utility-interactive inverter, or other certified device, that automatically isolates the generation equipment from the grid during an outage (August 2026). Operation of the renewable generation system, except for testing, prior to the installation of a new bi-directional meter is strictly prohibited (August 2026).

The table below outlines key FPL net metering guidelines:

How does FPL categorize Net Metering Systems by Tier?

FPL categorizes net metering systems into three tiers based on their alternating current (AC) rating (August 2026). The AC rating for a system is calculated by multiplying the array direct current (DC) rating by 0.85 (August 2026). This AC rating determines the tier that the system falls under for agreement purposes (August 2026).

What is the FPL Interconnection Application Process?

The interconnection process with FPL requires several steps to ensure compliance and safety. The customer on the account must complete an application and an interconnect agreement (August 2026). You must obtain a building permit for your system (August 2026). For Tier 2 and Tier 3 systems, you must also obtain proof of insurance and pay an application fee (August 2026).

Once construction is complete, you must provide FPL with post-construction documentation (August 2026). This includes a copy of the approved permit or a screen print from the local authority’s website indicating permit approval (August 2026). The required permit details include electrical and mechanical inspection sign-off, a description of work (e.g., solar, PV), the address of installation, the permit number, and the building department name (August 2026).

What are the requirements for a manual disconnect switch for FPL Tier 2 and 3 systems?

For Tier 2 and Tier 3 systems, FPL requires a manual disconnect switch of the visible load break type (August 2026). This switch provides a separation point between the AC power output of your renewable generation and any customer wiring connected to FPL’s system (August 2026).

The manual disconnect switch must be mounted separate from, but adjacent to, the FPL meter socket (August 2026). You must ensure that this switch remains readily accessible to FPL at all times (August 2026). It must also be capable of being locked in the open position with a single FPL utility padlock (August 2026). The disconnect switch should only disengage the renewable source, not all of your electrical service (August 2026).

A sign noting the location of the disconnect switch should be installed at the meter to enable FPL personnel to easily locate it in an emergency (August 2026). The disconnect switch should also have a warning sign indicating that both sides of the switch may be energized (August 2026).

Safety Note: Before operating any disconnect switch, always ensure power is killed first. Use insulated tools to avoid shorting. A spanner across a battery bank can short hundreds of amps, posing a severe hazard.

What are FPL's Guidelines for Battery Storage with Net Metering?

FPL's policy on battery storage is subject to change as the technology evolves and as legislative or regulatory action may dictate (August 2026). Battery storage equipment installed behind a customer’s meter must have a certification conducted by a Nationally Recognized Testing Laboratory (NRTL) to the current UL 1741 standard for safety (August 2026). A placard must be permanently affixed to the meter enclosure stating “Battery storage utilized in this facility” (August 2026).

Battery storage that is not UL 1741 certified must be DC coupled behind a UL 1741 listed device (August 2026). Under net metering, energy stored by the battery is only for the customer’s use (August 2026), and at this time, the customer may not export power from the battery to the grid (August 2026). Battery storage for Tier 3 systems will be reviewed in the fast track study (August 2026).

For battery storage systems installed without a renewable generation system and intended as an emergency backup power source, they may be charged from the electrical grid (August 2026). No interconnection agreement is required for these backup-only systems (August 2026). However, the customer is responsible for ensuring that power from the battery does not back-feed to the grid to avoid a safety hazard for workers or the public (August 2026). Customers assume all liability associated with the use of such battery systems (August 2026).

Safety Note: When working with batteries, always wear eye protection. Only add distilled or demineralized water to flooded lead-acid cells, never acid. If your system involves equalization or boost charging, ensure the area is well-ventilated and free of sparks or flames, as this drives the cell into the hydrogen gassing region. For any work inside the inverter or opening the enclosure, isolate PV, battery, and AC breakers, wait the manual's capacitor-discharge time, and note that opening the unit is authorized-service work.

How We Verified FPL Net Metering Information (August 2026)

We verified the FPL net metering guidelines, system tiers, and application requirements by consulting the official FPL website. All information presented in this article is directly sourced from the FPL Net Metering Guidelines page on fpl.com, accessed on August 23, 2026.

Understanding Potential Gaps in FPL Net Metering Information

While FPL provides comprehensive guidelines, some specific details are not publicly available on their net metering page (August 2026). For instance, the exact application process steps, forms, and fees are not detailed (August 2026). Specific insurance requirements, such as coverage amounts or types, for Tier 2 and 3 systems are not specified (August 2026).

Additionally, the full policy for "Battery storage continuously interconnected to the electric utility" is not fully detailed in the provided source (August 2026). There is no information on how FPL calculates "annual kWh consumption" for the 115% production limit, nor on the specific "additional expense" for systems exceeding 90% of service capacity (August 2026). We have not verified the process for FPL approval of remote switch locations or specific verbiage for warning signs (August 2026). For these specific details, you may need to contact FPL directly or consult with a qualified solar installer in Florida.

Planning Your Solar System for FPL Net Metering

Understanding FPL's guidelines is crucial when planning a solar installation in Florida. Proper system sizing ensures compliance with the production limit of less than 115% of your annual kWh consumption (August 2026). Considering your existing service capacity is also important, as systems exceeding 90% may incur additional expenses (August 2026). Use a solar sizing tool to estimate your energy needs and potential system output.
