Net Metering vs Net Billing: Solar Compensation Compared (2026)

If you own solar panels — or you’re planning to install them — the rules that govern how your utility pays you for surplus electricity will define your payback period. For two decades, net metering was the default in nearly every state: you got a one-to-one credit for every kilowatt-hour (kWh) you sent back to the grid. That golden era is ending. Most major utilities have moved (or are moving) to net billing, which pays solar exports at a much lower wholesale rate. The difference between these two compensation models can mean thousands of dollars over the life of a solar system.

This guide breaks down how each model works, where each one is still active, and what the shift means for solar economics in 2026.

What Is Net Metering?

Net metering is a billing arrangement where your electricity meter runs in two directions. When your solar system produces more power than your home uses, the excess flows back to the grid and the utility credits you at the retail rate — typically 12 to 35 cents per kWh, depending on your state. When you pull power from the grid at night or on cloudy days, you draw down those credits first before paying for any net consumption.

The math is elegant: every kWh you export is worth exactly the same as a kWh you import. A solar system can offset 100% of your electricity bill if it produces 100% of your annual consumption, even if your usage and production don’t line up hour-by-hour. The grid acts as a giant, free battery.

Where Net Metering Still Exists

Full retail-rate net metering (often called “NEM 1.0” or “NEM 2.0”) remains the law in a shrinking number of states, including parts of Massachusetts, New Jersey, New York, Illinois, and Maryland. Several Western states (Arizona, Nevada, California) have already transitioned away. Even where net metering still exists, most programs are capped — once a utility’s total solar capacity hits a threshold (commonly 5% to 10% of peak load), new customers are pushed onto the successor program.

What Is Net Billing?

Net billing — sometimes called “buy-all, sell-all” or “instantaneous netting” — treats your solar exports and your grid imports as two separate transactions. You buy electricity from the utility at the standard retail rate, and you sell your solar exports back at a different, usually much lower, rate called the export compensation rate or the avoided cost rate.

That export rate is typically tied to wholesale market prices and falls in the range of 3 to 8 cents per kWh — sometimes less. In California’s NEM 3.0 (now called the Net Billing Tariff), export rates vary hour-by-hour and can drop below 1 cent in spring afternoons when the grid is flooded with solar generation.

Why Utilities Pushed for the Change

Utilities argue that net metering shifts fixed grid costs (poles, wires, transformers, billing systems) onto non-solar customers, because solar owners pay less even though they still rely on the grid for backup and overnight service. Solar advocates counter that distributed solar reduces system-wide costs by cutting peak demand and deferring transmission investments. Both arguments have merit. The political reality is that utility commissions in most large states have sided with the utilities.

The Financial Difference Is Significant

Consider a 7 kW residential system in a state with 14 cent/kWh retail rates. The system produces 10,000 kWh per year, of which 4,000 kWh is consumed on-site and 6,000 kWh is exported.

• Under net metering: All 10,000 kWh offset retail-rate consumption. Annual bill savings: $1,400.
• Under net billing with a 4 cent export rate: 4,000 kWh × $0.14 (self-consumption) + 6,000 kWh × $0.04 (exports) = $800 savings.

That $600 annual gap compounds across a 25-year system life into roughly $15,000 in lost savings — enough to push the payback period from 7 years to 11+ years on a typical installation.

How to Maximize Value Under Net Billing

The economics of solar under net billing tilt heavily toward self-consumption. Every kWh you use on-site is worth the retail rate; every kWh you export is worth pennies. That changes which strategies pay back.

Add Battery Storage

A home battery lets you store midday solar production and discharge it in the evening when the sun is down but your usage is high. Under net billing, batteries pay back in 8 to 12 years; under old net metering, they rarely penciled out. The shift to net billing is the single biggest driver of residential battery sales in 2026.

Shift Load to Daytime

Run dishwashers, EV chargers, pool pumps, and laundry during peak solar hours. Smart load controllers (sometimes built into modern inverters) can automate this. Pre-cooling the house before evening rate peaks also helps.

Right-Size the System

Under net metering, oversizing was a free win — extra exports earned full credit. Under net billing, oversizing is wasteful. Most installers now design systems to match self-consumption rather than annual production. A smaller system with a battery often beats a larger system without one.

Net Metering vs Net Billing: Side-by-Side

Hybrid and Emerging Models

A handful of states are experimenting with middle-ground compensation. Value of Solar (VOS) tariffs in Minnesota and Maine attempt to calculate the full societal value of distributed solar (avoided fuel, capacity, emissions, transmission deferrals) and pay that rate to solar owners. Time-varying export rates in California pay more for solar exported during 4 p.m. to 9 p.m. peak hours than during midday surplus periods — explicitly designed to reward batteries that time-shift production.

Watch for these models to spread. They aim to preserve solar incentives while addressing utility cost-shift concerns more rigorously than blunt retail-rate netting did.

Frequently Asked Questions

Will my net metering grandfather status protect me?

In most states with successor tariffs, customers who interconnected under the prior rules remain on those rules for a defined period — typically 10 to 25 years. Always check your state PUC’s grandfather provisions before assuming. If you’re considering moving from a home with a grandfathered solar contract, recognize that the contract usually stays with the address, not the homeowner.

Can I switch electricity suppliers if my utility offers net metering?

Yes, in deregulated states. Your distribution utility handles net metering and the credit application, while your competitive supplier sets the generation rate. Solar exports are credited against the bundled bill in nearly all cases. Confirm with your utility before switching to make sure your interconnection agreement survives the switch.

Does community solar use net metering?

Community solar uses a related but distinct mechanism: virtual net metering (VNM) or bill credits. Subscribers don’t have panels on their roof; they buy a share of a remote solar farm and receive credits on their utility bill for their share of the output. Compensation rates vary widely by state.

What is a “non-bypassable charge”?

Even under generous net metering, most utilities require solar owners to pay a small per-kWh fee (typically 2 to 3 cents) on all electricity they import from the grid, regardless of how many export credits they have. This covers public-purpose programs, nuclear decommissioning, and similar charges that can’t be offset by self-generation.

Should I install solar before my state switches to net billing?

If your state has announced a transition date and you’re considering solar within the next 6 to 12 months, accelerating the project can lock in grandfathered net metering for 10 to 25 years. The financial difference often outweighs any rush on installer pricing. Get firm quotes and confirm interconnection lead times — utilities sometimes use queue dates rather than installation dates for grandfather eligibility.

Bottom Line

Net metering and net billing produce dramatically different solar economics. If you live in a state still operating under full retail-rate net metering, the window to lock in those terms is closing — and battery storage probably doesn’t pencil out yet. If you’re in a net billing state, design your system around self-consumption, plan for a battery, and shift flexible loads to daytime. Either way, your electricity supplier choice still matters: the rate you pay for grid imports is set by the supplier, not the utility, in deregulated markets.
