Net vs gross metering comes down to one question: how does your utility credit the electricity your solar panels send back to the grid? With net metering, your exports offset the power you pull from the grid, usually at the full retail rate. With gross metering, the utility buys every kilowatt-hour you produce at a separate rate and bills you for everything you use. This guide walks through how to tell which method applies to your home and how to compare the two.
Understand How Each Method Credits Your Solar Power
Under net metering, a bidirectional meter spins forward when you draw power and backward when your panels export surplus. At the end of the billing period, the utility nets those readings together. If you exported more than you used, you may carry a credit forward, depending on your utility’s rules.

Gross metering uses two separate measurements. One meter records all the energy your system produces, and the utility pays you for it at a set export rate. A second meter records everything you consume from the grid, and you pay for that at the normal retail rate. Your solar output and your household use are never offset against each other on the bill.
Check Which Method Your Utility Uses
Start by reading your current interconnection agreement or your utility’s net metering tariff. Look for the words “net metering,” “gross metering,” or “net billing.” Many utilities list the program name on their website under distributed generation or residential solar.
- Find your latest bill and note whether it shows one meter reading or two solar-specific readings.
- Locate your interconnection agreement and search for the metering type.
- Call the utility’s solar or interconnection department if the documents are unclear, and ask for the rate applied to exported energy.
- Record the export rate and the retail rate side by side. These two numbers drive your savings.
Compare the Financial Impact on Your Home
The main difference is the value of each kilowatt-hour you export. Net metering typically values exports close to the retail rate, so a kilowatt-hour you send out can cancel one you would otherwise buy. Gross metering usually pays a lower export rate, which means the same kilowatt-hour earns less.
| Factor | Net Metering | Gross Metering |
|---|---|---|
| How exports are valued | Offset against your use, often near retail rate | Paid separately at an export rate |
| Meter setup | One bidirectional meter | Two separate meters |
| Self-consumption benefit | Lower incentive to use solar on site | Higher incentive to use solar on site |
| Typical fit | Homes with high daytime export | Homes that use most of their solar power directly |
If your home uses most of its solar power during the day, gross metering may matter less, since less energy gets exported. Homes that send a lot of power to the grid benefit more from a generous net metering credit.

Factor in Your Local Policy and Future Changes
Metering rules change as utilities and regulators revisit their tariffs. Some programs add monthly fixed charges or reduce export credits for new customers. Before you commit to a system size, confirm the rules that will apply on the day your system is approved, not just the ones in place today. For example, Xcel Solar Rewards vs Net Metering (2026): Which Should You Choose? shows how program terms can shift the math.
Common Mistakes
- Assuming net metering always means full retail credit. Many programs pay less for certain exports or time periods.
- Sizing the system only on annual production without checking daytime use.
- Ignoring fixed monthly charges that reduce the value of any credit.
- Relying on installer estimates without asking for the exact export rate in writing.
- Forgetting that battery storage can change how much you export at all.

FAQ
Is net metering always better than gross metering?
Not always. Net metering usually gives a higher value for exports, but the answer depends on how much power your home uses during the day. A detailed comparison of your bill and production data will show which setup fits.
Can my utility switch me from net metering to gross metering?
Possibly, depending on your state and your utility’s rules. Changes often apply to new applicants first, but some programs also update existing customers. Check your tariff and ask the utility for written notice of any change.
Do I need a special meter for gross metering?
Usually yes. Gross metering typically requires a second meter to record your total solar output separately from your household consumption. Your utility or installer can confirm what equipment your area requires.
Conclusion
Net vs gross metering determines how much your solar exports are worth, so it shapes your payback period. Find out which method your utility uses, compare the export rate with your retail rate, and check for any upcoming policy changes. For specific billing questions, consult your utility or a licensed solar installer.
