Net energy metering states differ mainly in how they credit the power your rooftop system sends back to the grid. Some states still give full retail credit for every kilowatt-hour you export, which favors homeowners with large systems and little daytime use. Others have moved to net billing or time-of-use credits, which reward homes that match their battery storage to evening demand. If you want the simplest path, a full-retail net metering state usually wins; if you are building a new system with storage, a net billing or hybrid state often pays better over time.

Criteria Full-Retail Net Metering Net Billing / Time-of-Use Credits
Export credit value Matches your retail rate Often lower, varies by hour
Billing simplicity Monthly kWh rollover Hourly or export-rate tracking
Battery value Limited direct benefit Strong, shifts exports to peak hours
Rules for new systems Often closed to new customers Common in newer programs
Best system type Solar-only, sized to usage Solar plus battery

Credit Value Per Exported Kilowatt-Hour

Under full-retail net energy metering, each kilowatt-hour you send to the grid offsets one you would otherwise buy, at close to the full retail rate. That is the most generous structure for solar owners. Net billing states pay a separate export rate, which is often set by time of day and tends to be lower during midday hours when solar output peaks. Winner: full-retail net metering for raw credit value.

Billing Simplicity and Rollover

Net metering usually works on a monthly or annual true-up basis. Surplus kWh roll forward and offset future bills, which is easy to understand. Net billing requires your utility to track exports hour by hour and apply the matching rate, so statements are harder to check. Winner: net metering for homeowners who want predictable bills.

Battery Storage Compatibility

Batteries let you store midday solar and use it during the evening peak, when export rates and retail rates are highest. Net billing states reward this strategy directly, while full-retail states gain little because stored power already offsets usage at the same value. Winner: net billing for homes adding storage.

Eligibility for New Systems

Several states have capped or closed their net metering programs to new applicants, shifting new customers to export-rate schemes. Check whether your utility still accepts new interconnection applications before committing to a design. Winner: whichever structure your utility still offers, which is a question to settle first.

Pros & Cons

Full-retail net metering

  • Pro: Exports credited at close to retail rates.
  • Pro: Monthly rollover is simple to follow.
  • Con: Many programs no longer accept new customers.

Net billing and time-of-use credits

  • Pro: Pairs well with batteries and evening use.
  • Pro: Export rates can be set to reflect grid value.
  • Con: Bills are harder to verify and export rates may be lower.

Which Should You Choose?

Your best option depends on your state’s current program and how you plan to use power. Match your choice to your situation:

  • Full-retail net metering: Choose this if your utility still offers it and your home uses little power during the day. Consider a solar-only monitoring kit such as the Emporia Vue 3 Smart Home Energy Monitor to track exports (View on Amazon: View on Amazon).
  • Net billing with storage: Choose this if you plan a battery and your utility pays for exports by time of day. A battery such as the Tesla Powerwall 3 suits this approach (View on Amazon: View on Amazon).

FAQ

Do all net energy metering states still offer full retail credit?

No. Many states have reduced export credits or moved new customers to net billing. Check your utility’s current tariff before designing your system.

Is a battery worth adding under net metering?

It depends on your rate structure. Under full-retail net metering, a battery mainly provides backup. Under net billing with time-of-use rates, it can shift exports to higher-value hours.

Who should confirm the rules for my home?

Contact your utility and, for larger systems or financial decisions, a licensed solar installer or energy advisor who can review your specific tariff.

Conclusion

Full-retail net metering offers the strongest credit per kilowatt-hour, while net billing rewards homes that pair solar with storage. Confirm which structure your utility still accepts for new systems. Then size your array and battery to match your actual daytime and evening use.
