What Is Net Metering?
Net metering is a billing arrangement that allows homeowners with solar panels to sell their excess electricity back to the power grid in exchange for credits on their utility bill.
Here is the simple version: on a sunny afternoon, your solar panels likely produce more electricity than your home needs. Instead of letting that power go to waste, it flows back into the grid. Your utility company measures exactly how much you exported and credits your account — usually at the same rate you would pay to buy electricity. Later, at night or on cloudy days when your panels are not producing enough, you draw from the grid and use up those credits.
Think of the grid as a giant battery. During the day, you "deposit" extra solar energy. At night, you "withdraw" it. This is why net metering is sometimes called a virtual battery — and it is one reason solar is so much more valuable for grid-connected homes than for off-grid setups.
Net metering can reduce your annual electricity bill by 50–100% and shorten the payback period on your solar installation by several years. It is the single most important financial mechanism that makes residential solar worthwhile in most states.
How Net Metering Works, Step by Step
The process is automatic. Once your solar system is installed and your two-way meter is hooked up, net metering happens behind the scenes. But here is what is actually going on:
Check Solar Equipment Prices on AmazonYour Panels Generate Electricity
Sunlight hits your solar panels and is converted into usable AC electricity through an inverter. Your home is the first customer — it consumes whatever power it needs, right now.
Excess Electricity Flows to the Grid
When your panels produce more than your home is using — typically midday — the surplus flows backward through your meter and onto the utility distribution grid. Your neighbors might use that power.
Credits Accumulate on Your Account
Your net meter tracks both what you import from the grid and what you export. Modern digital meters record both directions separately. For every kWh you export, you earn a credit.
You Draw From the Grid at Night
When the sun goes down, your panels stop producing. Your home draws power from the grid as usual — but instead of paying for it immediately, you use the credits you banked during the day.
Monthly Billing: You Only Pay the Net Difference
At the end of each billing cycle, the utility compares your imports and exports. If you exported more than you imported, you get a credit balance. If you imported more, you pay for the difference. You may still owe a small grid connection fee each month regardless.
📊 Example: Monthly Net Metering Bill
Electricity imported from grid: 600 kWh
Electricity exported to grid: 800 kWh
Net exported: +200 kWh
Credit balance: +$30.00 (at $0.15/kWh)
Your bill for the month: $0 (plus any fixed grid fees) with 200 kWh of credits banked for next month.
Net Metering Rate Structures
Not all net metering is created equal. The rate at which your utility credits you for exported solar power is the single biggest factor in your solar investment financial return. Here are the three main rate structures:
| Rate Type | Credit per kWh Exported | Impact on Savings |
|---|---|---|
| Full Retail Net Metering (1:1) | Retail rate (12–25¢/kWh) | Best — maximum savings, 3–6 year payback typical |
| Avoided Cost / Wholesale | Wholesale rate (2–5¢/kWh) | Moderate to poor — exported power worth 75% less |
| VOIR / Value of Solar | Utility-calculated tariff rate | Variable — set by each utility, often below retail |
Some utilities also add a monthly grid access fee for solar customers — typically $10–$30/month — regardless of net metering. A few utilities have export caps that limit how much you can sell back, or time-of-use rates where the credit value changes depending on the time of day you export.
State-by-State Net Metering Policies (2026)
Net metering is regulated at the state level and can vary by individual utility. Here is a snapshot of key states as of 2026:
| State | Net Metering Status | Key Details |
|---|---|---|
| California | NEM 3.0 (reduced rates) | Export rates ≈ 5–8¢/kWh. Batteries strongly recommended. |
| Massachusetts | Net metering (retail rate) | Full retail credit with SMART program. Tier caps apply. |
| New Jersey | Net metering (retail rate) | Full retail credit. TRECs provide additional income. |
| New York | Net metering → VDER | Transitioning to Value Stack. Still competitive rates. |
| Pennsylvania | Net metering (retail rate) | Full retail credit. AECC and other utilities comply. |
| Arizona | EPSA rate (near retail) | EPSA rate pays near-retail. Slightly less than 1:1. |
| Colorado | Net metering (retail rate) | Full credit from Xcel Energy. Cap at 120% of usage. |
| Florida | Net metering (retail rate) | Full retail, but some utilities attempting to change. |
| Texas | Utility-specific | No statewide mandate. Austin Energy offers net metering; others vary. |
| North Carolina | Net metering (retail rate) | Full retail through Duke Energy. Caps on larger systems. |
| Georgia | Avoided cost rate | Export credits at avoided cost. No retail net metering. |
Always verify with your utility. Net metering policies change frequently. Check your utility distributed generation tariff or your state public utilities commission website for the latest rules. Some utilities grandfather existing solar customers under old rates when policies change.
Credit Banking & Annual Rollover
Solar production is seasonal — you generate far more power in summer than winter. Net metering credit banking is what makes solar practical year-round.
Here is how a typical annual cycle works:
📅 The Summer-to-Winter Credit Cycle
May – September: Panels overproduce. You build up credits each month.
October – April: Panels underproduce. You draw down stored credits.
Annual reconciliation: Remaining credits reset or paid out
At your annual "true-up" (the anniversary of your system interconnection), the utility reconciles your account. What happens to leftover credits varies:
- ✓ Full rollover — Unused credits carry into the new year
- ✓ Partial rollover — A percentage rolls forward; the rest paid at avoided cost
- ✓ Payout at wholesale — Remaining credits paid at avoided cost (a few cents/kWh)
- ✓ Zeroed out — All credits disappear at true-up
Strategy tip: If your utility zeros out leftover credits, size your system to produce roughly your annual consumption, not more. Oversizing wastes money in states without credit rollover.
NEM 3.0 and the Future of Net Metering
California NEM 3.0 (implemented April 2023) is the most significant net metering change in the U.S. and a bellwether for nationwide policy shifts.
Under NEM 2.0, California homeowners received near-retail credit for every kWh they exported. Under NEM 3.0, the export credit dropped dramatically — from roughly 25¢/kWh down to 5–8¢/kWh, a cut of about 75%. The reasoning: solar daytime peak is no longer as valuable because so many homes have panels, and the grid does not need midday solar as urgently.
📈 NEM 2.0 vs. NEM 3.0 Financial Comparison
| Metric | NEM 2.0 | NEM 3.0 |
|---|---|---|
| Export rate | ≈ 25¢/kWh (near retail) | ≈ 5–8¢/kWh |
| Annual earnings (5,000 kWh exported) | $1,250 | $250 – $400 |
| Solar payback period | 4 – 6 years | 8 – 12+ years |
| Battery economics | Optional | Strongly recommended |
Other states are watching California closely. Florida utilities have filed proposals to weaken net metering rates. Indiana has already adopted avoided-cost compensation for new solar customers. The national trend is clear: full retail net metering is becoming rarer.
How to Maximize Your Net Metering Credits
Here are proven strategies to get the most value from your net metering arrangement:
Size Your System to Annual Consumption
Design your system to produce roughly what you use in a year. Oversizing means excess credits that may be zeroed out at true-up. Undersizing means you still have high electricity bills. Review your last 12 months of utility bills to estimate your annual kWh usage.
Shift Energy Use to Daytime Hours
Run your dishwasher, washing machine, and EV charger during daylight hours. Using solar directly in your home is always more valuable than exporting it and earning credits, since you avoid both buying from and selling to the grid.
Track Your Export and Import Data
Most solar monitoring apps show real-time production and consumption. Check monthly to see if you are consistently over- or under-generating. This data helps you adjust usage patterns or plan for system expansion.
Consider a Battery in States With Weakened Net Metering
If your utility pays less than retail for exports, a battery lets you store noon production for evening use. Each kWh you use from the battery instead of the grid saves the full retail rate — far more than the export credit you would have received.
Take Advantage of Time-of-Use Rates
In states with TOU pricing, electricity is most expensive during peak evening hours (4–9 PM). If your net metering credits offset peak-rate consumption, each credit is worth more. Pair this with a battery for even greater savings.
Maintain and Clean Your Panels
Dirty panels produce less electricity, reducing both your on-site consumption and your export credits. Hosing down panels a few times per year (or during seasonal maintenance) can boost production by 5–15%.
Net Metering vs. Feed-In Tariffs vs. Buy-All
Net metering is not the only way utilities compensate solar owners. Here is how it compares to alternatives:
| Program Type | How It Works | Who Benefits Most |
|---|---|---|
| Net Metering (1:1) | Exported kWh credited at the retail rate you pay. Used to offset imports. | Homeowners with high daytime solar production and good credit rollover policies. |
| Feed-In Tariff (FIT) | All solar production sold to the grid at a guaranteed fixed rate for 15–20 years. You buy all your home electricity separately. | Investors seeking stable, long-term income. Rare in the U.S. now. |
| Buy-All / Sell-All | All generated power sold to the utility at wholesale/avoided cost. Home buys all power from the grid separately. | Generally the least favorable for homeowners. Used when net metering is not available. |
Bottom line: Net metering at full retail is the most beneficial arrangement for residential solar owners. It maximizes the value of every kWh you produce by crediting it at the rate you would otherwise pay. Feed-in tariffs provide predictable income but are rarely as lucrative. Buy-all arrangements should be avoided if any alternatives exist.
Frequently Asked Questions
What is net metering?
Net metering is a billing arrangement where your solar panels send excess electricity back to the grid, and your utility credits you for that power. During the day, your panels often produce more than you use. That extra electricity flows to the grid and accumulates as kilowatt-hour credits you can draw on later at night or on cloudy days.
Is net metering available everywhere?
No. Net metering policies are set at the state level and can vary by utility. States like California, Massachusetts, and New Jersey offer strong net metering, while others have replaced it with lower compensation rates. Some states have no formal net metering at all. Always check your utility current tariff for the exact rate and rules.
How much do utilities pay for excess solar power?
Under full net metering, you receive a one-to-one credit — one kWh exported equals one kWh credited at the retail rate. Under avoided-cost or VOIR rates, you may receive only the wholesale rate, typically 2–4 cents per kWh, which is far less than the retail rate of 12–25 cents per kWh.
What happens to my credits at the end of the year?
At your annual "true-up," the utility reconciles your account. Some utilities roll leftover credits into the next year. Others pay them out at the avoided-cost rate (a few cents per kWh). Some zero out the balance entirely. Check your utility net metering agreement for specific terms.
Does net metering work with battery storage?
Yes, and it changes the economics significantly. A battery lets you store excess solar for your own evening use instead of exporting it at a lower rate. In states where net metering has been weakened (like California NEM 3.0), pairing solar with a battery becomes much more financially attractive because you avoid exporting at wholesale and use more of your own generation.
Do I still have to pay my utility with net metering?
Usually, yes — but much less. Most utilities charge a monthly grid connection fee ($5–$30) even if you export more than you import. If your annual consumption exceeds your solar production, you will still owe for the net difference. However, many solar homeowners see their annual electricity costs drop from $1,500+ down to just a few hundred dollars.
Will net metering go away?
Full retail net metering is being phased down in many states, but existing customers are usually grandfathered. That means if you install solar while 1:1 net metering is still available, your rate is typically locked in for 15–20 years. This is another reason not to delay if your state currently offers favorable net metering.
