"One out of three Americans lives within 50 miles of high-level nuclear waste, some of which, like Plutonium, is lethally dangerous and will be around for an incredible longtime," John Oliver explained last night on Last Week Tonight.

According to the Nuclear Energy Institute, there is more than 71,000 tons of nuclear waste stranded at 104 reactors. "It was a problem we should have solved in the 1980s," Oliver said, "much like a Rubik's Cube."

Despite years of using nuclear energy, the country still doesn't have a permanent facility for its storage, the comedian said. Oliver proposed what the U.S. really needs is some kind of "nuclear toilet."

Through net metering programs, homeowners who have installed solar energy systems can get utility credits for any electricity their panels generate during the day that isn't used to power home systems. These credits can be "cashed in" to offset the cost of any grid electricity used at night.

Where net metering is available, solar panels have a shorter payback period and yield a higher return on investment. Without this benefit, you only save on power bills when using solar energy directly, and surplus generation is lost unless you store it in a solar battery. However, net metering gives you the option of selling any excess electricity that is not consumed within your home.

Generally, you will see more home solar systems in places with favorable net metering laws. With this benefit, going solar becomes an attractive investment even for properties with minimal daytime consumption. Homeowners can turn their roofs into miniature power plants during the day, and that generation is subtracted from their nighttime consumption.

What Is Net Metering?

Net metering is a billing arrangement in which surplus energy production from solar panels is tracked by your electricity provider and subtracted from your monthly utility bill. When your solar power system produces more kilowatt-hours of electricity than your home is consuming, the excess generation is fed back into the grid.

For homeowners with solar panels, the benefits of net metering include higher monthly savings and a shorter payback period. Utility companies also benefit, since the excess solar electricity can be supplied to other buildings on the same electric grid.

If a power grid relies on fossil fuels, net metering also increases the environmental benefits of solar power. Even if a building does not have an adequate area for rooftop solar panels, it can reduce its emissions by using the surplus clean energy from other properties.

How Net Metering Works

There are two general ways net metering programs work:

  1. The surplus energy produced by your solar panels is measured by your utility company, and a credit is posted to your account that can be applied to future power bills.
  2. The surplus energy produced by your solar panels is measured by your home's electricity meter. Modern power meters can measure electricity flow in both directions, so they tick up when you pull from the grid at night and count down when your solar panels are producing an excess amount of electricity.

In either scenario, at the end of the billing period, you will only pay for your net consumption — the difference between total consumption and generation. This is where the term "net metering" comes from.

How Does Net Metering Affect Your Utility Bill?

Net metering makes solar power systems more valuable for homeowners, as you can "sell" any extra energy production to your utility company. However, it's important to understand how charges and credits are managed:

  • You can earn credits for your surplus electricity, but utility companies will not cut you a check for the power you provide. Instead, they will subtract the credits from your power bills.
  • If your net metering credit during the billing period is higher than your consumption, the difference is rolled over to the next month.
  • Some power companies will roll over your credit indefinitely, but many have a yearly expiration date that resets your credit balance.

With all of this in mind, it is possible to reduce your annual electricity cost to zero. You can accumulate credit with surplus generation during the sunny summer months, and use it during winter when solar generation decreases.

You will achieve the best results when your solar power system has just the right capacity to cover your annual home consumption. Oversizing your solar array is not recommended, as you will simply accumulate a large unused credit each year. In other words, you cannot overproduce and charge your power company each month.

Some power companies will let you pick the expiration date of your annual net metering credits. If you have this option, it's wise to set the date after winter has ended. This way, you can use all the renewable energy credits you accumulated during the summer.

Is Net Metering Available Near You?

Net metering offers a valuable incentive for homeowners to switch to solar power, but these types of programs are not available everywhere. Net metering laws can change depending on where you live.

In the U.S., there are mandatory net metering laws in 38 states and Washington, D.C. Most states without a mandate have power companies that voluntarily offer the benefit in their service areas. South Dakota and Tennessee are the only two states with no version of net metering or similar programs.

If net metering is available in your area, you will be credited for your surplus energy in one of two ways:

  • Net metering at retail price: You get full credit for each kilowatt-hour sent to the grid. For example, if you're charged 16 cents per kWh consumed, you'll get a credit of 16 cents per kWh exported. This type of net metering is required by law in 29 states.
  • Net metering at a reduced feed-in tariff: Surplus electricity sent to the grid is credited at a lower rate. For example, you may be charged 16 cents per kWh for consumption but paid 10 cents per kWh exported. Feed-in tariffs and other alternative programs are used in 17 of the states where retail-rate net metering is not mandatory.

Note: This is just a simplified example — the exact kWh retail price and solar feed-in tariff will depend on your electricity plan.

The Database of State Incentives for Renewables & Efficiency (DSIRE) is an excellent resource if you want to learn more about net metering and other solar power incentives in your state. You can also look for information about solar incentives by visiting the official websites of your state government and utility company.

Other Financial Incentives for Going Solar

Net metering policies are one of the most effective incentives for solar power. However, there are other financial incentives that can be combined with net metering to improve your ROI:

  • The federal solar tax credit lets you claim 26% of your solar installation costs as a tax deduction. For example, if your solar installation had a cost of $10,000, you can claim $2,600 on your next tax declaration. This benefit is available everywhere in the U.S.
  • State tax credits may also be available depending on where you live, and they can be claimed in addition to the federal incentive.
  • Solar rebates are offered by some state governments and utility companies. These are upfront cash incentives subtracted directly from the cost of your solar PV system.

In addition to seeking out solar incentives available to you, you should compare quotes from multiple installers before signing a solar contract. This will ensure you're getting the best deal available and help you avoid overpriced offers and underpriced, low-quality installations.

Frequently Asked Questions: Solar Net Metering

Why is net metering bad?

When managed correctly, net metering is beneficial for electricity consumers and power companies. There have been cases in which power grids lack the capacity to handle large amounts of power coming from homes and businesses. However, this is an infrastructure issue, not a negative aspect of net metering itself.

In places with a high percentage of homes and businesses using solar panels, surplus generation on sunny days can saturate the grid. This can be managed by modernizing the grid to handle distributed solar power more effectively with load management and energy storage systems.

How does net metering work?

With net metering, any electricity your solar panels produce that isn't used to power your home is fed into your local power grid. Your utility company will pay you for this power production through credits that can be applied to your monthly energy bills.

Can you make money net metering?

You can reduce your power bills with net metering, using surplus solar generation to compensate for your consumption when you can't generate solar power at night and on cloudy days. However, most power companies will not pay you for surplus production once your power bill has dropped to $0. Normally, that credit will be rolled over, to be used in months where your solar panels are less productive.

On very rare occasions, you may be paid for the accumulated balance over a year. However, this benefit is offered by very few electric companies and is subject to limitations.

I'm a huge Trevor Hall fan so when I saw he was playing in my hometown of Cleveland, I was stoked. I knew seeing the show would be fantastic, but I was also thinking an interview with Trevor would be something really cool to give EcoWatch readers. So, lucky enough, I was offered an interview and was able to hop on my paddleboard from Whiskey Island on the shore of Lake Erie, head up the Cuyahoga River and get to the Music Box Supper Club just in time to chat with Trevor before the show.

"My dad was a drummer, so most my musical influence comes from my dad," Trevor said during our nearly hour interview. "Growing up, my dad had this CD collection in the hallway and I was always fascinated by all the CDs. My hobby was pulling out a CD that looked cool and I'd put it on the stereo and pretend I was rocking out. My dad was really into The Doobie Brothers, Allman Brothers, Earth Wind & Fire, Simply Red, and Crosby, Stills, Nash & Young."
