Net Metering Policies by State 2026: What Homeowners Earn

Net metering policies by state 2026 determine how much credit you receive for solar power sent to the grid, and those credits can make or break your solar payback period. A homeowner in one state may earn a full retail credit for every excess kilowatt-hour, while a neighbor across the border receives only a fraction of that value. As utilities and regulators continue to reshape compensation rules, understanding your state's current framework has never been more important for accurate solar savings projections.

This guide breaks down the national landscape, highlights the states with the strongest and weakest policies, explains the rise of net billing alternatives, and shows you how to verify the rules that apply to your specific address. Whether you are comparing quotes or simply trying to understand why installers quote different savings figures, the details below will help you ask better questions and avoid unpleasant surprises after your system is activated.

How Net Metering Works and Why It Matters in 2026

Net metering is a billing arrangement that lets you export surplus solar electricity to the grid and receive a credit on your utility bill. When your panels produce more power than your home consumes at that moment, the excess flows to the grid, and your meter effectively runs backward or records the export separately. At the end of the billing cycle, you pay only for your net consumption: the electricity you pulled from the grid minus the electricity you sent to it.

The value of that credit varies dramatically by state and even by utility. Under traditional net metering, each exported kilowatt-hour offsets a kilowatt-hour you would otherwise buy at the full retail rate. Under newer structures known as net billing or buy-all, sell-all, the utility pays a lower avoided-cost rate for exports, which reduces the economics of solar for the homeowner. The difference of a few cents per kilowatt-hour can add up to thousands of dollars over a system's 25-year life.

Three factors determine how favorable your state's policy is. First, the compensation rate: retail, avoided cost, or a time-of-use export rate. Second, the carryover rules: whether unused credits roll over indefinitely, reset annually, or are forfeited. Third, fixed charges and fees: some utilities impose monthly minimum bills or grid-access fees that reduce net savings. In 2026, more than a dozen states have moved away from full retail net metering, so verifying the current rules is essential before signing a contract.

States With the Strongest Net Metering Policies in 2026

A handful of states still offer full retail net metering with favorable carryover rules, making them the most attractive markets for solar investment. These states typically have strong renewable portfolio standards, active solar advocacy, and regulatory commissions that have resisted utility efforts to reduce compensation. If you live in one of these jurisdictions, your solar payback period is likely shorter and your long-term savings more predictable.

Leading states include California, New York, Massachusetts, New Jersey, and Illinois, though California's recent transition to net billing for new customers has complicated its status. New York and Massachusetts continue to offer robust credit structures with monthly or annual rollover. New Jersey maintains full retail net metering for systems up to a certain size. Illinois has a distributed generation rebate program that supplements net metering credits. These states also pair net metering with additional incentives like SRECs or state tax credits.

• New York: Full retail net metering with indefinite credit rollover for most utilities.
• Massachusetts: Retail rate credits with a cap on system size and monthly carryover.
• New Jersey: Full retail net metering for residential systems under 10 kW.
• Illinois: Net metering plus a distributed generation rebate that pays upfront.
• Colorado: Retail rate credits for exports, with some utilities offering time-of-use rates.

Even in these strong-policy states, utilities are actively petitioning regulators for changes. That means a homeowner installing solar in 2026 may lock in current rules for a decade or more, depending on grandfathering provisions. This makes early adoption more valuable, because later adopters may face less generous compensation. If you are considering solar in one of these states, obtaining quotes now and confirming the applicable tariff with your utility is a smart move.

States That Have Replaced Net Metering With Net Billing

Net billing, sometimes called net metering 2.0 or 3.0, pays homeowners a lower rate for exported electricity, often based on the utility's avoided cost rather than the retail rate. This structure is spreading rapidly as utilities argue that retail compensation shifts costs to non-solar customers. While net billing still allows you to offset your own consumption with solar, the economics of exporting power are far less attractive.

California led the way with its Net Energy Metering 3.0 (NEM 3.0) tariff, which took effect in 2023 and reduced export credits by roughly 75 percent for new customers. Since then, other states have followed. Nevada, Arizona, and Hawaii have all moved to net billing or similar structures. In Hawaii, the shift was driven by grid saturation concerns. In Arizona, utilities offer a lower export rate with time-of-use variations. Nevada's net billing pays a wholesale rate for exports.

For homeowners in these states, the path to strong savings increasingly involves pairing solar with battery storage. By storing excess solar in a battery and using it during peak evening hours, you avoid buying expensive grid power rather than selling it cheaply. This self-consumption strategy can restore much of the lost value under net billing. Many installers now design systems with batteries by default in these markets, and some utilities offer additional incentives for storage.

If you live in a net billing state, ask your installer to model two scenarios: one with solar only and one with solar plus storage. The difference in lifetime savings can be substantial, and the battery may pay for itself through avoided peak-rate purchases and utility storage rebates. Also check whether your utility offers a time-of-use rate that rewards evening exports, as some net billing tariffs do.

How to Find Your State's Exact Net Metering Rules

Rules can vary not just by state but by individual utility, so national summaries are only a starting point. Investor-owned utilities, municipal utilities, and rural electric cooperatives often have different tariffs. Some states mandate net metering for all utilities, while others allow cooperatives to set their own policies. That is why verifying your specific utility's current tariff is critical before you rely on any savings estimate.

Start with your state's public utility commission website, which publishes approved tariffs and dockets. Search for your utility's "net metering" or "distributed generation" tariff sheet. Look for the compensation rate, system size limits, carryover rules, and any fixed charges. If you cannot find it, call your utility and ask for the current net metering policy for new residential solar customers. Installers should also provide this information, but you should confirm it independently.

1. Visit your state public utility commission website and search for net metering dockets.
2. Locate your utility's tariff sheet and read the export compensation section.
3. Note the rate, any caps, and whether credits roll over monthly or annually.
4. Ask your installer to show the exact tariff they used in their savings model.
5. Confirm the policy with your utility in writing before signing a contract.

Another useful resource is the Database of State Incentives for Renewables and Efficiency (DSIRE), which tracks net metering rules by state and utility. Keep in mind that policies can change mid-year, so check the effective date. If your state is considering a transition to net billing, ask whether existing customers will be grandfathered under current rules. Grandfathering periods typically range from 10 to 20 years and can significantly protect your investment.

What Net Metering Changes Mean for Your Solar Savings

Changes in net metering policy directly affect your solar payback period and return on investment. Under full retail net metering, a typical system might pay for itself in seven to ten years. Under net billing with low export rates, that same system could take twelve to fifteen years or more, depending on how much solar you self-consume. The difference comes down to the value of each exported kilowatt-hour.

To estimate your savings under current rules, you need three data points: your utility's retail rate, its export compensation rate, and your home's hourly consumption profile. If you use most of your solar power on-site, the export rate matters less. If you are often away from home during sunny hours, you export more and rely on credits, making the export rate critical. Adding a battery or shifting heavy loads to daytime can improve self-consumption and reduce reliance on export credits.

It is also important to account for fixed charges. Some utilities impose a monthly grid-access fee or minimum bill that you pay regardless of solar production. These fees reduce net savings and can extend payback. When comparing quotes, ask installers to show savings net of all fixed charges. A system that looks great on gross production may deliver less if fees are high.

Finally, remember that net metering policies by state 2026 are not static. Utilities file rate cases regularly, and commissions can approve changes that affect new customers. Locking in current rules through grandfathering is a key advantage of installing sooner rather than later.

Understanding net metering policies by state in 2026 is the foundation of a smart solar decision. The rules determine how much you earn for excess power, how quickly your system pays for itself, and how much value you capture over decades. Start by identifying your state's current compensation structure, then verify the exact tariff with your utility. If you live in a state with strong retail net metering, acting before policy changes can lock in favorable credits for years. If you live in a net billing state, focus on self-consumption and storage to maximize savings. Either way, transparent information and careful comparison will help you get the most from your solar investment.
