How Net Metering Works - A Complete Guide
Net metering is the policy that makes residential solar financially viable for millions of homeowners. It allows you to send excess solar electricity back to the grid and receive a credit on your utility bill. Here is how it works and why it matters.
What Is Net Metering?
When your solar panels produce more electricity than your home uses during the day, the excess flows back to the utility grid. Your electric meter literally runs backward, giving you a credit. At night or on cloudy days when your panels produce less, you draw from the grid and those credits offset the cost.
At the end of each billing cycle, you only pay for the net electricity you consumed - hence the name net metering.
How Net Metering Saves You Money
Without net metering, any excess solar electricity would be wasted unless you had battery storage. Net metering effectively turns the grid into a free battery, storing your excess production as bill credits.
- Daytime overproduction - Your panels generate credits while you are at work
- Evening consumption - You use those credits when the sun goes down
- Seasonal balancing - Summer overproduction credits offset higher winter bills
The value of your credits depends on your state's net metering policy. Some states offer full retail rate credits, while others pay a reduced wholesale rate. Check the Electricity Rates by State tool to see current rates in your area.
Net Metering Policies by State
Net metering rules vary significantly across the country. Here are examples from three major solar markets:
- California - Transitioned to NEM 3.0 in 2023, which uses time-of-use export rates instead of full retail credits
- Texas - No statewide net metering mandate, but some utilities offer voluntary buyback programs
- Florida - Full retail rate net metering for systems up to 2 MW
Is Net Metering Going Away?
Several states have modified their net metering programs in recent years, but the trend is toward reform rather than elimination. Most utilities recognize that distributed solar provides grid benefits and are implementing updated rate structures rather than removing incentives entirely.
The key takeaway: if your state currently offers strong net metering, installing solar sooner rather than later locks in the current policy for your system's lifetime in many jurisdictions.
Frequently Asked Questions
Do all states have net metering?
No. While most states have some form of net metering or solar buyback program, policies vary widely. Some states mandate full retail rate credits, others offer reduced rates, and a few have no statewide policy at all.
Can I make money from net metering?
In most states, excess credits either roll over monthly or are paid out at a reduced rate at year-end. It is rare to receive a check larger than your annual electricity costs, but net metering can effectively eliminate your electric bill.
Does net metering work with battery storage?
Yes. With a battery, you can store excess solar for personal use and only export to the grid when your battery is full. This strategy is especially valuable in states where export credits are lower than the retail electricity rate.
