Solar Clarity Guide

If you’re considering solar panels, net metering might be the single most important concept you need to understand — because it determines how much money you’ll actually save each month. In simple terms, net metering lets you send unused solar electricity back to the power grid and get credited for it on your utility bill. But the details matter a lot: your state, your utility company, and your system size all affect what you actually earn.

This guide breaks it all down — no jargon, no fluff — so you can decide if net metering makes solar worth it for your home.

What Is Net Metering?

Net metering (also called net energy metering or NEM) is a utility billing arrangement that credits solar panel owners for the electricity they add to the grid. Here’s the core idea:

• Your solar panels produce electricity during the day — often more than your home uses.
• That excess power flows back into the utility grid.
• Your electric meter runs backward (or a separate meter tracks the export).
• At billing time, you’re charged only for the net amount of electricity you consumed — what you used from the grid minus what you sent to it.

That’s why it’s called net metering — you pay for the net difference between consumption and production.

How Net Metering Works: Step by Step

Let’s walk through a typical day for a solar homeowner with net metering:

Step 1: Solar Panels Produce Power During the Day

From roughly 9 AM to 4 PM on a sunny day, your panels may produce 3–5 kWh per hour. But most families aren’t home — the washer isn’t running, the TV is off, and AC demand is lower than in the evening. So your panels are producing more than you’re using.

Step 2: Excess Power Flows to the Grid

Your inverter converts the DC electricity from your panels to AC electricity, which flows into your home and then the grid. Your utility meter measures this outflow and records the kilowatt-hours you exported.

Step 3: You Draw Power From the Grid at Night

After sunset, your panels stop producing. You pull electricity from the grid like normal — for your refrigerator, lights, TV, and phone chargers. This usage is tracked as your consumption.

Step 4: Your Bill Shows the Net Difference

At the end of the billing cycle, your utility calculates: kWh consumed from grid − kWh exported to grid = net kWh billed. If you exported more than you consumed, you may receive a credit that rolls over to next month.

Net Metering Example: Real Numbers

Here’s what net metering looks like in practice for a home in Texas with a 7 kW solar system:

Month	Solar Produced	Home Used	Exported to Grid	Net Bill
June (peak sun)	980 kWh	1,100 kWh	350 kWh	~$15 (base fees only)
December (low sun)	490 kWh	900 kWh	50 kWh	~$70
April (mild weather)	750 kWh	650 kWh	200 kWh	$0 + credit rollover

In sunny months, excess production covers cloudy months. Over a full year, many homeowners with properly sized systems reduce their electric bill by 70–100%.

Net Metering Rates: Full Retail vs. Avoided Cost

Here’s where it gets nuanced. Not all net metering credits are equal. There are three main compensation structures:

1. Full Retail Rate (Best for Homeowners)

You’re credited at the same rate you pay for electricity. If electricity costs $0.13/kWh, you get $0.13 credit for every kWh you export. This is the most common structure in states with strong net metering laws like California (historically), New Jersey, and Massachusetts.

2. Avoided Cost / Wholesale Rate (Less Favorable)

Some utilities credit you at the wholesale rate — what it costs them to generate power — typically $0.03–$0.07/kWh. This significantly reduces your savings. States like Nevada partially shifted to this model, which caused a major backlash (and was later partially reversed).

3. Time-of-Use (TOU) Net Metering

Credits vary based on when you export. Power exported at peak demand times (5–9 PM) is worth more than power exported midday. California’s current NEM 3.0 policy uses this structure, which has reduced solar incentives for new installations — but it also rewards homeowners who add battery storage.

Net Metering by State: Where Does It Apply?

As of 2026, net metering policy varies significantly by state. Here’s a quick breakdown:

State	Net Metering Status	Compensation Rate	Notes
Texas	Voluntary by utility	Varies	No statewide mandate; depends on your utility
California	Yes (NEM 3.0)	TOU-based	Reduced export credits for new systems post-2023
Florida	Yes	Retail rate	Strong net metering; great solar state
New Jersey	Yes	Retail rate	One of the best net metering programs
Arizona	Yes (modified)	Varies	Export rate lower than retail
New York	Yes (Value of DER)	Varies by location	Complex but generally favorable
Georgia	Limited	Retail rate	Georgia Power required to offer it

Important: Even within a state, policies differ by utility company. Always verify with your specific utility before making any decisions. Rural electric cooperatives often have different rules than investor-owned utilities.

Does Net Metering Work With Battery Storage?

This is a critical question as more homeowners add Tesla Powerwall, Enphase IQ Battery, or other storage systems. The short answer: it depends on your net metering policy.

In most cases, your battery charges during the day from your solar panels. At night, you draw from the battery instead of the grid — which reduces how much you pull from the grid but also reduces your daytime exports (so you earn fewer credits). Whether adding a battery improves or reduces your net metering savings depends on your TOU rates and local policy.

In California’s NEM 3.0 specifically, batteries actually increase your savings because you can discharge stored power during peak TOU hours (when grid electricity is most expensive) instead of exporting midday surplus at low credit rates.

How Net Metering Affects Your Solar Payback Period

Net metering is one of the top factors determining how quickly your solar system pays for itself. Here’s the general impact:

• Full retail net metering: Payback period typically 6–9 years
• Avoided cost / wholesale rate: Payback period typically 10–14 years
• No net metering (self-consumption only): Payback period typically 12–18 years

The difference between full retail net metering and no net metering can literally be 5–10 years of extra payback time. It’s that significant. Before you buy solar, confirm your utility’s net metering policy in writing — not just from a solar salesperson.

Net Metering vs. Feed-in Tariff: What’s the Difference?

You might also hear the term feed-in tariff (FiT). Here’s how they differ:

	Net Metering	Feed-in Tariff
How it works	Offsets your bill with credits	Pays you a fixed rate for every kWh exported
Typical rate	Your retail electricity rate	Set by government or utility (varies widely)
Best for	Offsetting your own consumption	Maximizing exports to the grid
Common in	United States	Germany, UK, Australia, parts of Japan

In the U.S., net metering is far more common than feed-in tariffs, though some states and utilities offer small FiT programs in addition to or instead of net metering.

Frequently Asked Questions About Net Metering

Does every state have net metering?

No. As of 2026, most states have some form of net metering, but it’s not federally mandated. About 40 states have mandatory net metering policies. In states like Texas, it’s offered voluntarily by some utilities but not others. Always check with your specific utility company.

What happens to my net metering credits at the end of the year?

This varies by state and utility. Most utilities let credits roll over month-to-month indefinitely. Some states do an annual true-up where unused credits at the end of the year are either paid out (sometimes at a lower rate), forfeited, or carried forward. California’s NEM does an annual true-up in April.

Can I get net metering if I rent my home?

Generally no — net metering requires you to be the utility account holder and install solar on a property you control. However, some states have community solar programs that let renters subscribe to a shared solar farm and receive bill credits similar to net metering. Check if your state has a community solar program.

Will net metering be eliminated?

Some utilities have lobbied to reduce or eliminate net metering, and a few states have scaled it back (like California with NEM 3.0). However, the IRA federal solar incentives through 2032 have kept the policy environment favorable. Most existing solar owners are protected by grandfathering clauses when policies change.

Do I still need utility service with net metering?

Yes. Net metering is a grid-tied arrangement — you remain connected to the utility grid and pay a minimum monthly service fee (typically $10–$30/month) regardless of how much solar you produce. Going completely off-grid requires a large battery system and is a different setup entirely.

How do I find out if my utility offers net metering?

Call your utility company directly and ask: (1) Do you offer net metering or a similar program? (2) What is the export credit rate? (3) Is there a system size limit? (4) How long does interconnection approval take? You can also check the DSIRE database at dsireusa.org, which tracks solar incentives and policies by state.

Bottom Line: Is Net Metering Worth It?

If your state has full retail net metering, it’s one of the strongest financial reasons to go solar. It effectively turns your electric meter into a savings account — you deposit power during the day and withdraw it at night, paying only for any shortfall. In states with strong net metering, properly sized solar systems can eliminate 80–100% of your electric bill.

If your state has reduced or no net metering, solar can still make sense — especially if you add battery storage — but your savings will be lower and your payback period longer. Run the numbers carefully before you commit.
