Net Metering Policies by State 2026: Your Complete Guide to Solar Export Credits
Net metering remains available in all 9 NuWatt service states as of March 2026, but credit rates are declining in several. As of 2026, roughly a third of U.S. states have reduced, replaced, or are actively revising traditional one-to-one retail net metering, with some changes like California's NEM 3.0 slashing export values by 75% or more overnight. At least 41 states plus Washington D.C. currently have some form of net metering policy, but what that actually means for your electricity bill varies enormously—a solar homeowner in Massachusetts can earn roughly $0.30 per kilowatt-hour while a homeowner in Idaho might receive as little as $0.04 per kWh, a difference that can shift the payback period on an identical system by five years or more.
What is Net Metering and How Does It Work?
Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. When your solar panels produce more electricity than your home is consuming (typically during midday hours), the excess flows to the grid and your electric meter effectively runs backward. At night or during cloudy periods when your panels produce less than you consume, you draw electricity from the grid normally.
The mechanism sounds simple, but the devil is in the details. The rules governing credit rates, carryover periods, monthly true-ups, and eligible system sizes have become a patchwork of state commission orders, legislative mandates, and utility tariffs that change almost every year. Understanding your specific state's rules directly impacts your solar return on investment.
Why Did Net Metering Policies Change in 2026?
The Section 25D residential solar investment tax credit expired December 31, 2025, with no federal tax credit for homeowner-purchased solar in 2026, making net metering and state-level incentives (SMART in MA, ADI in NJ, REG in RI) even more critical to solar economics.
The political reality: Utilities are well-funded lobbyists, solar advocates are well-organized but often outspent, and the resulting policies usually land somewhere between what's fair and what's favorable to incumbent utilities. Utilities argue that solar homeowners still rely on the grid for backup power but pay less toward maintaining it, claiming this shifts grid maintenance costs to non-solar customers—a concept called the "cost shift" or "cross-subsidy."
How Do States Compare? Top Performers vs. Declining Policies
| Tier | States | Credit Rate | Key Details |
|---|---|---|---|
| Full Retail (Tier 1) | New Jersey, Massachusetts, Maine, New York, Maryland, Connecticut, Vermont. Maine benefits from high retail rates of $0.27–$0.32/kWh combined with full retail net metering. | 1:1 at retail rate | New Jersey offers full 1:1 retail credit with no cap, plus the ADI program adding $85.90/MWh in production-based payments for 15 years. |
| Partial Retail (Tier 2) | Arizona, Florida, Nevada, Rhode Island, Delaware | 50-85% of retail | Rhode Island post-April 2023 systems receive approximately 80% of retail rate, while grandfathered pre-April 2023 systems retain 1:1 credit. |
| Avoided Cost / Net Billing (Tier 3) | California (NEM 3.0), Arkansas, Idaho, Indiana, Illinois | $0.04-0.08/kWh | California Public Utilities Commission approved the new NEM 3.0 structure in December 2022, cutting average export credits by more than 75% for new applicants. |
Which States Offer the Best Net Metering in 2026?
- New Jersey: New Jersey arguably leads the country in 2026 with full 1:1 retail credit with no cap, plus the ADI program adding $85.90/MWh in production-based payments for 15 years, making solar payback periods as short as 5–7 years.
- Massachusetts: The average retail rate in Massachusetts reached $0.30/kWh in early 2026, making each exported kWh highly valuable, with the state also running separate Solar Massachusetts Renewable Target (SMART) incentive payments stacked on top of net metering credits.
- New York: A 25% state tax credit (up to $5,000), full net metering, sales tax exemption, and property tax exemption create a strong incentive package, with permitting improving.
- Maryland: Maryland offers full retail credit plus SREC income and a $1,000 state grant with moderate rates ($0.16/kWh) but strong incentive stack.
- Connecticut: Connecticut offers full retail credit with some of the highest retail rates in the country ($0.29/kWh) and fast payback periods of 5-7 years.
- Oregon: Oregon passed House Bill 2618 in 2023, preserving retail-rate net metering for residential customers and capping utility-proposed reforms until 2028, with the bill requiring the Oregon PUC to complete a full cost-allocation study before any rate structure changes can take effect.
- Vermont & Maine: Vermont and Maine round out the top tier, with Maine benefiting from high retail rates of $0.27–$0.32/kWh combined with full retail net metering.
- New Hampshire: New Hampshire's NEM 2.0 is locked through 2041—the most secure long-term net metering guarantee.
States Under Watch: Where Policies Are Declining
Net metering is under pressure in multiple states: Vermont has cut rates 7 years in a row, Pennsylvania's PPL utility is proposing a 60-80% reduction, and Rhode Island already slashed credits in 2023. Duke Energy filed petition to reduce NEM credits for new solar customers, with a PUC docket opened Q1 2026.

California's NEM 3.0: The Model Other States Are Watching
California's shift from NEM 2.0 to NEM 3.0 (Net Billing Tariff) in April 2023 is the most significant net metering policy change in US history, with exports credited at full retail rate (~$0.30-$0.35/kWh on average under NEM 2.0, but a 7 kW system exporting 40% of production earned about $1,600-$1,900/year in export credits.
New California customers installed after April 15, 2023 receive NEM 3.0 credits averaging around $0.05/kWh for exports—down from roughly $0.30/kWh under NEM 2.0, with systems installed before that date grandfathered under NEM 2.0 for 20 years, and NEM 3.0 economics generally requiring pairing solar with battery storage to make financial sense.
A California solar owner who would have saved $150/month under NEM 2.0 might save $40-60/month under NEM 3.0 with solar alone, but adding a battery can recover savings to $100-130/month because you're storing cheap midday solar and using it during expensive peak hours instead of exporting it for pennies—in California, solar without a battery no longer makes strong financial sense, but solar with a battery still does, especially given the state's extreme retail electricity rates.
Impact of Federal Tax Credit Expiration on Net Metering Economics
The federal 30% Investment Tax Credit (ITC) expired at the end of 2025, with new systems installed in 2026 not qualifying for this credit, fundamentally changing the economics of solar in most states. In 2026, with the federal residential solar tax credit (Section 25D) expired, net metering is more important than ever because it is now the single largest financial driver of residential solar ROI in most states.
This shift has made state-level incentives and net metering policies the primary financial drivers for residential solar adoption. Most net metering contracts are guaranteed for 20-year terms, which means every project you close today locks in that ROI for your customer for two decades—that's a powerful close. For solar installers and companies communicating this value proposition to homeowners, understanding regional policy differences is critical.

Battery Storage: Essential or Optional in Your State?
In reduced-rate markets like California, batteries can improve solar economics by storing excess generation for use during expensive peak hours rather than exporting at low rates, but in states with good net metering (full retail credit), batteries typically don't improve financial returns due to their $10,000-20,000 cost, though they do provide energy security during outages.
In most net billing markets—California, Arizona, Nevada, Indiana—battery storage is necessary, as it allows customers to maximize self-consumption during peak hours rather than exporting at low rates, making the system far more financially viable. The decision to add storage should depend on your state's specific net metering rate structure.
Frequently Asked Questions About Net Metering Policies by State in 2026
Which states offer the best net metering in 2026?
Massachusetts, New Jersey, Maryland, Vermont, and Oregon consistently rank at the top because they offer full retail-rate credits, 12-month carryover, and no restrictive system size caps. New Jersey leads with full 1:1 retail credit plus additional ADI production payments, while Massachusetts combines high electricity rates ($0.30/kWh) with full retail net metering and the SMART program.
What is the difference between net metering and net billing?
Net metering credits solar exports at the full retail electricity rate, while net billing credits exports at a lower rate—usually the utility's avoided cost, and the difference can mean thousands of dollars in lost savings over a system's lifetime. California's NEM 3.0 is the most visible example of net billing, paying just $0.05-0.08/kWh instead of $0.30/kWh.
Can net metering policies change after I install solar?
Yes, though most states have grandfathering provisions protecting existing customers for 10–20 years, with Florida grandfathering pre-2024 installations through 2029, California's NEM 2.0 grandfathering running 20 years from the interconnection date, Nevada's grandfathering covering 20 years from its 2015 policy change, and a 15–20 year protected window covering most of the financially critical payback period for a typical residential system.
What is the deadline for locking in California NEM 2.0 rates?
If your system was submitted for interconnection before April 2023, you could lock in NEM 2.0 rates—but only if your system achieves Permission to Operate (PTO) by April 15, 2026, and if you're one of the remaining NEM 2.0 applicants who hasn't finished installation, the clock is ticking. This is a critical date for California homeowners considering solar.
Is battery storage necessary for solar in every state?
In most net billing markets—California, Arizona, Nevada, Indiana—yes, battery storage is necessary as it allows customers to maximize self-consumption during peak hours rather than exporting at low rates, making the system far more financially viable. However, in states with full retail net metering, batteries are optional for financial optimization.
How do state-level incentives affect net metering value in 2026?
There is no federal tax credit for homeowner-purchased solar in 2026, and net metering and state-level incentives (SMART in MA, ADI in NJ, REG in RI) are now the primary financial drivers for residential solar economics. This means state incentives stack on top of net metering credits, creating strong financial packages in states like Massachusetts and New Jersey.
How much can net metering impact my solar payback period?
Net metering is one of the most important factors in solar economics, with this single policy potentially swinging your solar payback period by 3-5 years. The difference between a state offering full retail net metering and one offering avoided-cost rates can add or subtract years to your system's financial performance.
Which states are likely to change their net metering policies in 2026-2027?
States likely to see net metering changes in the coming years include North Carolina, Florida, Georgia, and Virginia. SEIA tracks active policy proceedings in more than a dozen states in 2026 alone. Monitor your state's public utilities commission website for active dockets if you're considering solar.
People Also Ask
What is the average net metering credit rate across all US states in 2026?
A solar homeowner in Massachusetts can earn a retail-rate credit of roughly $0.30 per kilowatt-hour for every unit they export to the grid, while a homeowner in Idaho might receive as little as $0.04 per kWh under an avoided-cost structure. This 10x variation across states makes location the single most important factor in solar economics.
How do time-of-use rates affect net metering credits in 2026?
As retail electric rates continue to rise (3-5% annually across the Northeast), the dollar value of net metering credits increases proportionally, with a 1:1 credit at $0.28/kWh in 2026 potentially worth $0.36/kWh by 2032. Time-of-use structures may pay more for afternoon exports when grid demand is highest.
Are there states without net metering requirements in 2026?
A handful of states have weak or no net metering policies: Alabama has no statewide net metering with TVA offering a very limited buyback program, and Tennessee has TVA service territory with limited programs through local utilities. However, roughly 38 states plus Washington D.C. still carry some form of net metering or net billing.
What is the grandfather clause and how does it protect solar owners?
When states change net metering rules, they almost always include a grandfather clause that protects existing solar customers, meaning customers who installed solar under the old rules keep their original NEM rate for a defined period—typically 10-20 years from interconnection, making this the single most important reason to consider installing solar sooner rather than later in states where NEM changes are being discussed, as every month you wait is a month closer to potentially less favorable terms.
How has the expiration of the federal 30% tax credit affected solar economics in 2026?
In 2026, with the federal residential solar tax credit (Section 25D) expired, net metering is more important than ever because it is now the single largest financial driver of residential solar ROI in most states, and every dollar of net metering credit value directly impacts your payback period, with a state that cuts net metering from 1:1 retail to 50% retail potentially doubling your payback period overnight.
What role does municipal utilities play in net metering vs. investor-owned utilities?
LADWP net metering credits solar exports at full retail rates in 2026, unlike NEM 3.0, with Los Angeles homeowners on LADWP having one of the most valuable net metering arrangements left in California with full retail-rate credits worth $0.22 to $0.37 per kilowatt-hour, while Southern California Edison and PG&E customers now receive roughly $0.08 per kWh for solar exports under NEM 3.0. Municipal utilities often retain more favorable policies than investor-owned utilities.
