Net billing and net metering are the two main ways utilities credit homeowners for solar power sent back to the grid. Net metering usually wins for homeowners who want simple, one-for-one credits for every kilowatt-hour they export. Net billing tends to suit households in states that have moved to pay exported power at a lower, time-based rate, and it rewards homes that can shift usage away from peak hours.

Criteria Net Metering Net Billing
How exported power is credited Usually one-for-one against retail rates Paid at a separate export rate, often lower
Credit timing Monthly or annual roll-over Usually hourly or monthly, depending on the utility
Effect of battery storage Limited direct benefit Stronger benefit when you shift exports to peak hours
Predictability of savings Easier to estimate Depends on rate design and your usage pattern
Administrative complexity Simpler billing More detailed billing and interval data

How Each Model Credits Your Solar Power

Under net metering, the meter spins backward when your panels push power to the grid, and that surplus offsets what you pull later. Most programs credit at the full retail rate, so a kilowatt-hour sent to the grid is worth roughly a kilowatt-hour you buy back. Winner: net metering for simple, generous credits.

Net billing separates the two directions. Exported power is valued at an avoided-cost or export rate set by the utility or regulator, while the power you draw from the grid is billed at retail. The export rate is often lower and can vary by hour. Winner: net billing only if you can time your exports to higher-value hours.

Time-of-Day Value and Battery Storage

Net billing rewards timing. A home with a battery can store midday solar and release it during the evening peak, when export or avoided-cost rates are highest. Under net metering, the timing of your exports usually matters far less, so a battery adds fewer financial benefits. Winner: net billing for households with storage or flexible loads like EV charging on a schedule.

Predictability and Billing Simplicity

Net metering is easier to forecast. If your system produces 8,000 kWh a year and you use 8,000 kWh, the credits roughly balance out, and you can estimate the outcome with basic arithmetic. Net billing requires you to know your hourly production and usage profile, which is harder for most people to model. Winner: net metering for predictable, low-effort planning.

Long-Term Policy Risk

Many states have been shifting from net metering to net billing, sometimes with a grandfathering period for existing systems. If you are considering solar now, check whether your utility is moving to a new export rate and when the change takes effect. Owners who install before a transition often keep their original terms for a set number of years. Winner: depends on your state’s timeline; grandfathered systems usually keep the better deal.

Pros & Cons

Net Metering

  • Pro: Exports are credited close to full retail rates, which keeps payback periods shorter.
  • Pro: Simple monthly or annual billing that is easy to understand.
  • Con: Little reward for storage or shifting load, and policy support may be phased out.

Net Billing

  • Pro: Rewards batteries and time-of-use strategies that align exports with peak hours.
  • Pro: Often matches how modern grids value power at different times of day.
  • Con: Export rates are usually lower, and savings are harder to predict.

Which Should You Choose?

Your best option depends on your state’s rules, your household’s usage pattern, and whether you plan to add storage. If your utility still offers net metering, it is usually the simpler and more generous choice. If net billing is your only option, the math is different, so plan around it.

  • Choose net metering if you want straightforward credits and your utility still offers it. A common pick for this model is a grid-tie inverter such as the SolarEdge SE7600H-US, which many installers specify for residential systems. View on Amazon
  • Choose net billing if you plan to add a battery or can shift usage to midday and evening peaks. A battery such as the Tesla Powerwall 3 is often paired with net billing systems to store midday production. View on Amazon
  • Stay on net metering if you are grandfathered and your current terms are favorable. Changing contracts rarely helps once you are locked in.

FAQ

Is net billing always worse than net metering?

Not always. Net billing can outperform net metering for homes with batteries or flexible loads that export during high-value hours. For a typical home without storage, net metering usually produces higher credits.

Can I switch from net metering to net billing?

Switching depends on your utility and regulator. Many programs apply the new model only to new interconnections, while existing systems may keep their current terms for a set period. Contact your utility to confirm your options.

Do I need a battery for net billing?

A battery is not required, but it helps most under net billing because it lets you time exports to higher-value hours. Without storage, you still earn credits, but the timing benefits are limited.

Conclusion

Net metering offers simpler, more generous credits and suits most homeowners who can keep their current terms. Net billing rewards timing and storage, which makes it a better fit for households willing to plan around peak hours. Check your utility’s current rules before you commit to either path.
