Maximizing Your Solar Investment with Net Metering in 2026

Navigating the landscape of solar incentives and policies can be complex for homeowners considering an installation in 2026. The shift from traditional net metering to net billing is changing how homeowners recover their investment. This guide helps you understand these changes and optimize your solar system design, particularly with battery storage.

Understanding Net Metering and Net Billing

At its core, net metering allows solar homeowners to send excess electricity generated by their panels back to the utility grid. A bidirectional meter tracks both electricity consumed from and exported to the grid¹. The way utilities compensate for this exported energy varies significantly.

Traditional Net Metering: The Gold Standard

Traditional net metering credits each kilowatt-hour (kWh) exported to the grid at the full retail electricity rate. This means the credit you receive for sending power back to the grid is the same price you would pay to buy power from the utility. This 1:1 retail rate credit is considered the "gold standard" for solar homeowners. It can potentially eliminate or significantly reduce monthly electricity bills².

However, unused net metering credits can expire at the end of an annual billing cycle or be paid out at a lower "avoided-cost" rate, depending on state regulations¹.

Net Billing: A Lower Compensation Model

Net billing (or Net Billing Tariff) compensates for exported solar electricity at a lower rate, typically the utility's "avoided cost" or wholesale rate, rather than the full retail rate². Under net billing, exported electricity is generally compensated at a rate below the retail electricity rate, although the methodology and amount vary significantly by state and utility.

For example, under California's Net Billing Tariff, export compensation is based on avoided-cost values and varies by time rather than receiving a fixed retail-rate credit.

Designing Your Solar System for Evolving Policies

The national trend in the US is towards reduced solar export rates, with full retail export credits being replaced by lower-rate net billing structures². This shift changes how homeowners should approach system design.

Maximizing Self-Consumption

Full-retail net metering reduces the financial disadvantage of exporting excess solar because eligible exports may receive credits close to the retail rate.

However, in net billing markets, the objective shifts to maximizing the value of each kWh by prioritizing self-consumption and timing exports to high-rate windows³. Right-sizing a solar system to the load and integrating battery storage is a more effective design strategy under net billing².

The Role of Battery Storage

Battery storage can become more valuable in net billing markets because it allows homeowners to store excess solar for later use rather than exporting it at lower compensation rates. Batteries enable homeowners to store excess solar energy for evening use or during expensive time-of-use (TOU) rate periods⁴. This is crucial because electricity is most expensive during peak evening hours⁵.

While battery systems represent an added upfront cost, they can significantly improve the financial viability of solar in net billing states. Battery storage can improve the value of solar under California's Net Billing Tariff by allowing homeowners to shift electricity use or exports to higher-value periods. In 2026, residential battery systems cost $1,100-$1,300 per kWh of capacity, with a typical 13.5 kWh system costing over $15,000 installed before incentives⁶.

Some states and utilities offer incentives for battery storage, such as ConnectedSolutions programs in MA, CT, RI, VT, providing $225-275/kW/year⁴.

State-Specific Net Metering and Net Billing Policies (2026)

Net metering or alternative export-compensation programs are available across much of the US, but policies vary substantially by state and utility. Some states, like South Dakota, Tennessee, and Alabama, have minimal to no statewide net metering or similar programs². Some states grandfather eligible customers under existing compensation structures for a defined period, but the length and eligibility rules vary by state and utility.

States with Strong Net Metering

Several states with strong net metering and full retail 1:1 credits in 2026 include:

• New Jersey: Offers full retail credits with no cap, plus additional ADI production-based payments.

• Massachusetts: Provides 1:1 retail credits plus SMART program incentive payments.

• New York: Continues to offer full 1:1 retail credits for residential systems up to 25 kW. Customers can choose between Phase One net metering (full retail with a monthly Customer Benefits Charge) or the Value of Distributed Energy Resources (VDER) program. New York's current policy locks in 1:1 net metering for 20 years for systems interconnected in 2026⁷. Con Edison solar customers in New York are subject to a small Customer Benefit Contribution (CBC) charge⁸. For more details, see our Complete guide to New York net metering.

• Maryland, Connecticut, and Vermont: These states also maintain strong net metering². However, Connecticut added a $0.0402/kWh Solar Energy Adjustment for new 2026 interconnections, effectively reducing credit by about 15%. Vermont has experienced 7 consecutive years of rate cuts for solar exports⁴.

• Florida: As of September 2026, Florida maintains full retail rate net metering for existing and new solar customers of investor-owned utilities. Legislative attempts in Florida (e.g., HB 741 in 2022) to reduce net metering credits were vetoed and did not become law. Florida utilities may require solar systems to be sized to match historical consumption. In Florida, excess credits may expire or be compensated at a lower avoided-cost rate annually, depending on the utility¹. Discussions are ongoing in Florida about potential future changes, including a gradual reduction in retail-rate credits after 2026 and enhanced incentives for battery storage.

• Ohio: Ohio's net metering policies in 2026 remain intact with retail credits (up to a 120% system cap), reaffirmed by PUCO in January.

States Transitioning to Net Billing

States transitioning to or already implementing net billing with reduced export rates in 2026 include:

• California: NEM 3.0 (Net Billing Tariff) became effective on April 15, 2023, and survived its final legal challenge in June 2026. Under NEM 3.0, mandatory Time-of-Use (TOU) rates are required for all customers in California⁵.

• Nevada, Arkansas, Arizona, and Indiana: These states are also implementing net billing with reduced export rates². For specific details on Arizona's program, see What you need to know about Arizona’s net billing program.

• Rhode Island: Rhode Island reduced solar credits to approximately 80% of retail in 2023⁴.

States Without Mandatory Statewide Net Metering

Texas has no statewide mandatory net metering. The deregulated ERCOT market in Texas allows Retail Electric Providers (REPs) to offer optional "solar buyback plans" with varying rates (e.g., 3 cents to retail-match). Austin Energy (Texas) uses a Value of Solar (VoS) tariff, crediting solar production at 12.89 cents/kWh for systems under 1 MW, effective October 1 2026⁹, while customers pay full retail for imports. CPS Energy (San Antonio, Texas) offers 1:1 net metering up to monthly consumption, then pays wholesale for excess.

Federal Incentives in 2026

The federal Residential Clean Energy Credit under Section 25D is no longer available for residential solar expenditures made after December 31, 2025. State, local, and utility incentives may still be available in 2026.

Making Your Decision

The value of solar in 2026 depends heavily on your state's specific net metering or net billing policies. A properly sized solar system can substantially reduce electricity costs, depending on system production, household consumption, utility rates, fixed charges and export compensation. In states with net billing, solar remains a sound investment, but requires a more strategic approach.

Recommendation: Check whether your state's current program offers grandfathering before installing, as eligibility periods and compensation protections vary. If you are in a net billing state, or one transitioning to it, prioritize system design that maximizes self-consumption and includes battery storage². Adding battery storage can mitigate the impact of reduced export rates by enabling greater self-consumption and better alignment with Time-of-Use rates⁵.

Always consult with local solar installers. They can provide accurate information on current state and local incentives, help size your system correctly, and advise on battery integration specific to your utility's rates.
