Net Metering in 2026: How It Works

Net metering is the billing arrangement that lets your solar panels turn your utility meter into a two-way account: when your panels make more power than your home uses, the excess flows back to the grid and you earn a credit; when your home needs more than the panels produce, you pull from the grid and spend those credits. In 2026, net metering is still the single biggest factor in how much a residential solar system actually saves — but what a credit is worth now varies enormously by state and utility, and some of the most generous programs have been scaled back.

What net metering credits are worth

The value of each exported kilowatt-hour (kWh) depends on your state’s policy. Here’s the general landscape in 2026:

Policy type	What you earn per exported kWh	Example markets
Full retail net metering	Same rate you pay to buy power	Many Northeast & Midwest states
Net billing / avoided cost	Below retail (wholesale-ish rate)	California (NEM 3.0), parts of the West
Buy-all/sell-all	Fixed export rate, separate from usage	A handful of utilities
No mandated program	Whatever the utility chooses (often low)	Some Southeast markets

Under full retail net metering, a kWh you export is worth exactly as much as a kWh you buy — the best possible deal for solar owners. Under net billing, exports are credited at a lower wholesale-style rate, so sending power to the grid is worth much less than using it yourself in real time.

What drives the value of your credits

Your state’s rules. This is the dominant factor. Full-retail states make solar pay back faster; avoided-cost states stretch payback out.

Time-of-use rates. Many utilities now credit exports based on when they happen. Power sent to the grid at 1 p.m. (when supply is high) may be worth a few cents, while power you’d otherwise buy at 7 p.m. can cost far more. This gap is what makes batteries attractive — you store cheap midday production and use it during expensive evening hours.

Credit rollover and true-up. Some programs let unused credits roll month to month and settle once a year; others reset monthly or pay out excess at a low rate. Rollover rules quietly determine whether an oversized system is worth it.

Fixed charges and minimum bills. Even with net metering, most utilities charge a monthly connection or minimum fee you can’t zero out with solar credits.

Grandfathering. When a state changes its rules, existing customers are often locked into the old terms for a set number of years. The date you interconnect can matter as much as the policy itself.

California and NEM 3.0

California is the clearest example of how much policy matters. In April 2023 the state moved from NEM 2.0 (essentially retail credit) to NEM 3.0, officially called the Net Billing Tariff. Under NEM 3.0, exported power is credited at avoided-cost values that are roughly 75% lower than the old retail credit, and those values shift hour by hour.

The practical result in 2026: in California, sending solar power to the grid earns very little, so the winning strategy is to use or store your own production. That’s why battery attach rates on new California systems are now high — a battery lets you keep the power you make instead of exporting it for pennies. If you’re modeling a California system, pairing panels with storage is close to essential to hit a reasonable payback. See our home battery cost guide for the numbers.

How net metering affects payback

Net metering and payback are tightly linked. In a full-retail state, every kWh your panels produce offsets a retail kWh, so a well-sized system can erase most of your bill and pay for itself faster. In an avoided-cost state, you only capture full value on the power you use as you make it — the rest is credited low — so payback lengthens unless you add storage.

Because the federal tax credit for purchased residential systems was repealed for installations after December 31, 2025, net metering carries even more weight in 2026: with no 30% credit softening the up-front cost for buyers, your savings rate — set largely by your net-metering policy — is what drives the return. We walk through the full timeline in our solar payback period guide.

How to find your policy

1. Check your utility, not just your state. Investor-owned utilities, municipal utilities, and co-ops can run different programs in the same state.
2. Ask installers for a bill-offset estimate specific to your utility’s tariff, not a generic “you’ll eliminate your bill” claim.
3. Look up the export rate and true-up rules in the tariff document — the words to search for are “net metering,” “net billing,” or “avoided cost.”
4. Confirm the grandfathering window so you know how long your terms are locked in.

FAQ

Does net metering mean my bill goes to zero? Rarely all the way. Even a system sized to cover 100% of your usage usually leaves a monthly fixed charge or minimum bill you can’t offset with credits.

Is net metering going away? No, but it’s evolving. Several states have shifted from full retail credit to lower net-billing rates. Existing customers are often grandfathered under the older, more generous terms for a set period.

What’s the difference between net metering and net billing? Net metering typically credits exports at the retail rate; net billing credits them at a lower avoided-cost or wholesale-style rate. Net billing makes self-consumption and batteries more valuable.

Do I need a battery to benefit from solar in 2026? Not everywhere. In full-retail states, panels alone still pay well. In avoided-cost states like California under NEM 3.0, a battery dramatically improves the economics.

Will an oversized system earn me a check from the utility? Usually not a meaningful one. Most programs pay out excess annual credits at a low rate, so building a system much larger than your usage rarely pays off.

Does the repealed federal tax credit change net metering? No — they’re separate. Net metering is a utility billing rule; the tax credit was a federal purchase incentive. But with the buyer credit gone in 2026, strong net metering matters more to your overall return.
