How Net Metering Works and How to Maximize It

If you have solar panels on your roof or you are thinking about getting them, net metering is one of the most important concepts you need to understand. It is the mechanism that lets you earn credit for the extra electricity your panels produce, and it can make or break the financial case for going solar.

In this guide, we will walk you through exactly how net metering works, which states still offer the best policies, what California's controversial NEM 3.0 means for the industry, and the strategies you can use to squeeze every dollar of savings out of your solar investment in 2026.

What Is Net Metering?

Net metering is a billing arrangement between you and your electric utility. When your solar panels produce more electricity than your home needs at any given moment, the extra power flows back into the grid. Your utility tracks that exported energy and gives you a credit on your electric bill. Later, when your panels are not producing enough to cover your usage, like at night or on cloudy days, you pull electricity from the grid as usual. At the end of each billing period, the utility calculates the difference between what you sent out and what you pulled in.

If you used more electricity than you exported, you pay for the net difference. If you exported more than you used, you carry a credit forward to the next month. Over the course of a year, many solar homeowners find that their credits from sunny months cover their grid usage during darker winter months, resulting in electric bills that are dramatically lower or sometimes close to zero.

The whole system relies on a bi-directional meter that your utility installs when your solar system is connected to the grid. This meter can measure electricity flowing in both directions, tracking both your consumption from the grid and your exports to it.

How Net Metering Works Step by Step

Understanding the daily rhythm of net metering helps you see why timing and strategy matter so much.

During a typical sunny day, your solar panels start generating electricity at sunrise. In the morning hours, your home is using power for things like the refrigerator, coffee maker, and lights, so most of the solar electricity is consumed on the spot. As the sun climbs higher and your panels hit peak production around midday, they often generate more power than your home needs. That surplus flows through your meter and into the grid, and your utility records a credit.

In the late afternoon and evening, as the sun drops and your household usage spikes with cooking, laundry, heating or cooling, and entertainment, your panels produce less than you need. You draw from the grid to make up the difference. Your meter tracks that consumption.

At the end of the billing cycle, your utility nets out the two numbers. If you sent 800 kWh to the grid and pulled 600 kWh back, you have a net surplus of 200 kWh credited to your account. If you sent 500 kWh but consumed 700 kWh, you pay for the 200 kWh net difference at whatever rate applies to your plan.

This straightforward math is what makes net metering so powerful for solar homeowners. You are essentially using the grid as a giant battery, storing your excess production during the day and withdrawing it when you need it later.

Net Metering, Net Billing, and Feed-in Tariffs: What Is the Difference?

Not all solar compensation programs work the same way, and the terminology can be confusing. Here is how the three main models compare.

Traditional net metering credits your exported electricity at the full retail rate. If you pay 30 cents per kWh for grid electricity, you receive 30 cents per kWh in credit for every unit you send back. This one-to-one exchange makes the math simple and the savings substantial.

Net billing also tracks your exports and imports, but it credits your exported power at a lower rate than retail, often based on the utility's "avoided cost" or wholesale market prices. You might pay 30 cents per kWh to buy from the grid but only receive 8 cents per kWh for what you export. California's NEM 3.0, which we will discuss in detail below, is the most prominent example of this model.

Feed-in tariffs are a different structure entirely, more common in Europe than the United States. Under a feed-in tariff, all the electricity your system produces is sold to the grid at a fixed rate, and you buy all your household electricity separately. This model uses two meters and typically offers rates designed to guarantee a return on your solar investment.

The trend across the United States is a gradual shift from traditional net metering toward net billing. Understanding where your state falls on this spectrum is essential for making good decisions about system sizing, battery storage, and overall solar economics.

Net Metering Policies by State in 2026

The value of net metering varies enormously depending on where you live. As of 2026, approximately 38 states plus Washington, D.C. require utilities to provide some form of solar compensation, but the specific terms differ significantly.

States with Strong Full-Retail Net Metering

Several states continue to offer the gold standard of net metering: one-to-one credits at the full retail electricity rate. If you live in one of these states, the financial case for solar is especially compelling.

New Jersey offers full retail rate credits worth approximately 26 cents per kWh, making it one of the most lucrative net metering markets in the country. Massachusetts expanded its net metering program in early 2025, raising the automatic eligibility threshold from 10 kW to 25 kW AC, which covers the vast majority of residential systems. Pennsylvania and Maine both provide one-to-one retail rate credits applied monthly.

Other states maintaining strong retail credit structures include Arkansas, Florida, Illinois, and Virginia, though Virginia's policies are under active review. Starting in 2024 for Appalachian Power customers and 2025 for Dominion Energy customers, the State Corporation Commission is reassessing how new net metering customers are compensated.

If you are considering solar and live in a full-retail net metering state, the advice is straightforward: the current policies make solar an excellent investment, but there is no guarantee they will last forever. Many of these states are watching California's experience and may eventually follow suit with reforms.

States with Reduced or Modified Compensation

A growing number of states have moved away from full retail credits. California is the most prominent example with its NEM 3.0 net billing tariff, which compensates exports at roughly 25 percent of retail rates. Arizona has reduced export compensation to encourage on-site consumption. Indiana and Nevada use revised credit structures tied to wholesale pricing, and Hawaii operates under a net billing framework with reduced export rates.

States with No Mandatory Compensation

A handful of states, including Alabama, South Dakota, and Tennessee, have no state-level requirement for utilities to compensate solar customers for exported electricity. If you live in one of these states, the economics of solar depend entirely on self-consumption: using the power you generate rather than sending it to the grid.

California's NEM 3.0: What Happened and What It Means

California's experience with NEM 3.0 deserves special attention because it represents the direction many states may be heading, and it has fundamentally changed how solar economics work in the nation's largest rooftop solar market.

In April 2023, California replaced its traditional net metering policy with the Net Billing Tariff, commonly known as NEM 3.0. Under the new rules, the compensation for exported solar electricity dropped by roughly 75 percent, from retail rates of 30 to 35 cents per kWh down to avoided cost rates averaging around 8 cents per kWh.

The impact was immediate and dramatic. Solar installations in California dropped by approximately 80 percent in the months following the change. The solar industry was hit hard, and many installers were forced to lay off workers or close their doors.

However, the market has been adapting. Battery storage attachment rates, meaning the percentage of new solar installations that include a home battery, jumped from about 11 percent before NEM 3.0 to nearly 70 percent by the end of 2024. This shift makes sense: if the grid will only pay you 8 cents for your excess solar but you would pay 30 or more cents to buy electricity back during peak hours, storing that energy yourself is far more valuable than exporting it.

For new California solar customers in 2026, the economics still work, but they look different than they used to. Homeowners who purchase solar-plus-battery systems with cash can expect to offset 70 to 90 percent of their electric bills, with payback periods between five and seven years. Solar-only systems face longer payback periods of eight to ten years.

One important deadline to be aware of: if you submitted a grid interconnection application before April 14, 2023, you have until April 15, 2026 to complete your installation and connection to qualify for the older, more favorable NEM 2.0 rates for 20 years. That deadline is just weeks away as of this writing.

NEM 3.0 is also facing legal challenges. In August 2025, the California Supreme Court ordered the Court of Appeal to reconsider the policy's legality, and a ruling is expected by mid-2026. While this could potentially lead to changes, solar shoppers should not count on it and should make decisions based on current rules.

How to Maximize Your Net Metering Savings

Regardless of where you live or which compensation model your state uses, there are proven strategies to get the most out of your solar investment.

Right-Size Your System

The single most important decision is sizing your solar system to match your actual electricity consumption. If your state offers full retail net metering, a system that produces roughly 100 percent of your annual usage is ideal. You will generate surplus credits in sunny months and use them in darker months, minimizing your annual bill.

In states with reduced export compensation, slightly undersizing your system can actually be smarter. You want to maximize the percentage of solar electricity you consume directly, because every kWh you use yourself saves you the full retail rate, while every kWh you export earns you much less. Check out our complete guide to solar panel costs for help estimating what size system you need.

Understand Time-of-Use Rates

Many utilities have moved to time-of-use (TOU) rate structures, where the price of electricity varies throughout the day. Typically, off-peak hours (late night to early morning) are cheapest, while on-peak hours (usually 4 to 9 PM) are the most expensive.

This matters for net metering because your solar panels produce the most energy during midday, which is often an off-peak or mid-peak period. If your exported solar is credited at midday rates but you consume grid electricity during expensive peak hours, the math may not work in your favor.

The solution is to shift your energy usage. Run your dishwasher, washing machine, and other heavy appliances during the day when your panels are producing. Charge your electric vehicle during solar hours. The more of your own solar electricity you consume directly, the more you save.

A solar monitoring system can help you track your production and consumption in real time, making it much easier to shift usage to match your solar output.

Pair Your Solar with Battery Storage

Battery storage has gone from a nice-to-have to a game-changer for solar economics, especially in states that have moved away from full retail net metering.

The logic is simple. Instead of sending your excess midday solar to the grid and receiving a small credit, you store it in a battery. Then, during expensive peak evening hours when your panels are not producing, you draw from your battery instead of the grid. Every kWh you use from your battery saves you the full retail rate of electricity, which can range from 15 to 40 cents per kWh depending on your utility and rate plan.

In California and other reduced-compensation states, this strategy roughly yields five times the savings value compared to exporting the same energy to the grid. The difference between an 8-cent export credit and a 35-cent avoided purchase is enormous over the course of a year.

A typical home battery system like the Tesla Powerwall or Enphase IQ Battery costs between $1,100 and $1,300 per kWh of capacity in 2026, with a standard 13.5 kWh system running about $15,000 installed. That is a significant investment, but in states with reduced net metering compensation, the payback can be surprisingly fast.

When Do Batteries Not Make Financial Sense?

It is worth being honest: batteries do not always pencil out purely on financial terms. If you live in a state with full retail net metering and flat electricity rates, the grid is essentially acting as a free battery for you. Exporting at 30 cents and importing at 30 cents gives you the same result as storing and using it yourself, without the cost of a battery.

In those states, the main reasons to add a battery are backup power during outages and future-proofing against potential policy changes. Both are valid reasons, but they are not the same as a pure financial return.

The strongest financial case for batteries exists in states with avoided-cost compensation (like California), time-of-use rate structures with large peak-to-off-peak differentials, or areas with frequent grid outages where backup power has real dollar value.

Monitor and Optimize

An energy management system can automate much of this optimization for you. Modern systems can learn your usage patterns, track utility rate schedules, and automatically decide when to charge your battery, when to discharge it, and when to export to the grid. This kind of intelligent management can add 10 to 20 percent more savings compared to a set-and-forget approach.

What About the Federal Solar Tax Credit?

One important factor for 2026 solar shoppers: the Section 25D residential solar investment tax credit expired on December 31, 2025. There is currently no federal tax credit for homeowner-purchased solar installations.

This changes the economics significantly. Under the previous 30 percent credit, a $30,000 solar-plus-battery system would have qualified for a $9,000 tax reduction. Without that incentive, you are paying full price.

However, state-level incentives remain available in many markets. Programs like Massachusetts' SMART program, New Jersey's ADI, and Rhode Island's REG continue to provide meaningful financial support.

Common Questions About Net Metering

What happens to my credits at the end of the year?

Most net metering programs have an annual "true-up" period. At the end of the year, your utility calculates your total credits and total consumption. Policies vary on how excess annual credits are handled. Some states require the utility to pay you for surplus credits (often at a reduced rate), while others simply reset your balance to zero. Check your state's specific rules, because this affects how you should size your system.

Can I sell my electricity for a profit?

In most net metering programs, no. The credits offset your bill but do not result in a cash payment that exceeds your total annual bill. Some states do compensate for annual surplus, but typically at avoided-cost rates rather than retail. Net metering is designed to reduce your bill, not turn your home into a power plant for profit.

Does net metering work with community solar?

Yes, many states have community solar programs that use a form of virtual net metering. You subscribe to a share of a solar farm located elsewhere, and the credits generated by your share are applied to your utility bill. This is a great option if your roof is not suitable for solar panels or if you rent your home.

What happens if my state changes its net metering policy?

Most states grandfather existing solar customers under the terms that were in place when they connected their system. California, for example, grandfathers NEM 2.0 customers for 20 years. However, the length and terms of grandfathering vary by state, so this is an important detail to confirm before you install.

The Bottom Line

Net metering remains one of the most valuable incentives for going solar, even as policies evolve and compensation structures change across the country. If you live in a state with full retail net metering, the financial case for solar is as strong as it has ever been. If you live in a state that has shifted to net billing or reduced compensation, battery storage has become the key to making the numbers work.

The landscape is changing quickly. About one-third of states are actively revising their net metering policies, and the trend is clearly moving toward lower export compensation. If you have been considering solar, there is a genuine urgency to act while your state's current policies are still in place. Systems installed under favorable net metering rules are typically grandfathered for years or even decades.

Whatever your situation, the strategies are clear: right-size your system, understand your rate structure, pair with batteries when the math supports it, and shift your usage to maximize self-consumption. Do those things, and net metering can still deliver thousands of dollars in savings over the life of your solar investment.
