Florida's Net Metering Step-Down Schedule
Florida's net metering policy has undergone a fundamental restructuring that is reshaping the economics of commercial solar installations across the state. Under the revised framework approved by the Florida Public Service Commission, the credit rate for excess solar generation exported to the grid follows a declining schedule that reduces the value of solar exports over time.
In 2025, commercial net metering customers received credits at 75 percent of the full retail rate for excess generation sent back to the grid. In 2026, that credit drops to 60 percent of the retail rate, representing a 20 percent reduction in the value of exported solar energy. The step-down schedule continues through 2029, when credits will reach approximately 40 percent of the retail rate, effectively matching the utility's avoided cost of wholesale generation.
For commercial property owners who installed solar systems under the original full-retail net metering framework, the step-down represents a material change in the financial return on their investment. For those considering new installations, the declining credit structure fundamentally changes the system design calculus, favoring self-consumption optimization and battery storage over maximum generation capacity.
The Economics Before and After the Step-Down
To understand the impact of the net metering step-down on commercial solar economics, consider a typical 200 kW rooftop installation on a retail center in South Florida. Under the previous full-retail net metering policy, every kilowatt-hour exported to the grid was credited at the same rate the building paid for grid electricity, roughly 11 to 14 cents per kWh depending on the rate schedule.
Pre-Step-Down Economics
Under full retail net metering, a 200 kW system generating approximately 300,000 kWh annually could produce total energy value of $33,000 to $42,000 per year, including both self-consumed energy and exported credits valued at full retail. With installed costs of approximately $400,000 to $500,000 after federal tax credits, the simple payback period was typically 10 to 13 years, with a 20-year net present value well into positive territory.
2026 Step-Down Impact
At the 60 percent credit rate effective in 2026, the same system sees its export credit value reduced significantly. If the system exports 40 percent of its generation to the grid, the annual value of those exports drops from approximately $15,000 at full retail to $9,000 at 60 percent retail. The total annual energy value declines by $6,000 or more, extending the simple payback period by 2 to 3 years and reducing the 20-year NPV by $50,000 to $80,000.
The net metering step-down has not killed commercial solar in Florida, but it has fundamentally changed the design approach. Systems sized purely to maximize generation are being replaced by systems sized to maximize self-consumption, often paired with battery storage that can shift excess generation to peak demand periods rather than exporting it to the grid at reduced credit rates.
Battery Storage as the New Essential
The most significant market response to the net metering step-down has been the surge in battery storage attachment rates for commercial solar installations. In 2024, approximately 35 percent of new commercial solar projects in Florida included battery storage. By early 2026, that figure has jumped to approximately 70 percent, driven almost entirely by the declining value of grid exports.
How Batteries Change the Math
Battery storage allows commercial buildings to capture excess solar generation that would otherwise be exported at reduced credit rates and instead use that energy during peak demand periods when grid electricity is most expensive. A properly sized battery system can increase the self-consumption ratio of a solar installation from 55 to 65 percent without storage to 80 to 90 percent with storage.
The financial benefit comes from two sources. First, every kilowatt-hour shifted from export to self-consumption is valued at the full retail rate rather than the reduced net metering credit, adding 4 to 6 cents per kWh in incremental value. Second, batteries can be programmed to discharge during the building's peak demand windows, reducing the demand charge component of the electric bill. For buildings on demand-based rate schedules, the demand charge savings alone can justify 30 to 50 percent of the battery investment.
Battery Sizing for Commercial Buildings
The optimal battery size for a commercial solar installation depends on the building's load profile, the solar system's generation curve, and the utility's rate structure. For most Florida commercial buildings, a battery capacity equal to 25 to 40 percent of the solar system's rated capacity provides the best balance between cost and value. For a 200 kW solar system, this means a battery system in the 50 to 80 kW range with 2 to 4 hours of duration, costing approximately $80,000 to $160,000 installed.
System Design Strategies for the New Framework
Commercial solar developers and property owners in Florida are adopting several design strategies to optimize financial returns under the revised net metering framework.
- Right-sizing to load: Rather than maximizing rooftop coverage, systems are being sized to match 70 to 80 percent of the building's daytime load, minimizing excess generation that would be exported at reduced rates. This approach leaves some roof space unused but produces a higher return per dollar invested.
- West-facing panel orientation: Some installers are tilting panels to the west rather than due south to shift generation later in the day, better matching afternoon peak demand periods and reducing the amount of midday excess that needs to be stored or exported.
- Time-of-use rate optimization: For buildings on time-of-use rate schedules, solar-plus-storage systems can be programmed to maximize savings by charging batteries during solar production hours and discharging during the highest-rate periods, capturing rate differentials that can exceed 5 cents per kWh.
- Demand charge management: Battery systems are increasingly being configured with demand charge management as the primary use case, with net metering export avoidance as a secondary benefit. This approach prioritizes the highest-value savings stream and can deliver a faster payback than pure solar self-consumption optimization.
Federal Incentives That Offset the Step-Down
While the net metering step-down reduces the value of exported solar, federal tax incentives continue to make commercial solar-plus-storage installations financially attractive. The Investment Tax Credit provides a 30 percent credit on the total installed cost of solar systems, and the standalone storage ITC now extends the same 30 percent credit to battery installations regardless of whether they are paired with solar.
The combination of the 30 percent ITC for both solar and storage, bonus depreciation under MACRS, and the additional 10 percent adder for projects in energy communities can reduce the effective cost of a commercial solar-plus-storage installation by 40 to 55 percent. When these federal incentives are factored into the analysis, the economics of commercial solar in Florida remain compelling despite the net metering step-down, particularly for buildings with high daytime loads and significant demand charges.
Property managers evaluating solar-plus-storage should work with qualified tax advisors to ensure they capture all available incentives and structure the installation to maximize the combined value of federal credits, depreciation benefits, energy savings, and demand charge reduction. The window for the most generous incentive levels extends through 2032 under current law, creating a multi-year planning horizon for portfolio-wide solar deployment.
Planning Your Florida Solar Strategy
The net metering step-down does not eliminate the case for commercial solar in Florida, but it demands a more sophisticated approach to system design, financing, and operation. Property managers should take the following steps to develop an informed solar strategy for their Florida portfolios.
- Analyze building load profiles. Before sizing any solar system, develop detailed 15-minute interval load data for each candidate building. The load profile determines the optimal system size, the expected self-consumption ratio, and the potential value of battery storage.
- Model multiple scenarios. Run financial models comparing solar-only, solar-plus-storage, and storage-only configurations for each building. Include the full net metering step-down schedule through 2029 and projected rate increases from utility rate cases.
- Evaluate third-party ownership. Power purchase agreements and solar leases from third-party developers can transfer the net metering risk to the developer while providing the property with immediate savings. Some developers are now offering solar-plus-storage PPAs that bundle both technologies into a single contract with a guaranteed rate.
- Monitor policy changes. Florida's net metering framework continues to evolve, and additional policy changes affecting distributed generation, interconnection, and rate design are likely in the coming years. Property managers should stay engaged with industry associations and regulatory proceedings to anticipate changes that could affect existing or planned solar investments.
