How Does Net Metering Work? 7 Things (2024) You Have to Know

Does your electricity bill give you a fright every time it arrives?

Then you may be wondering, “How does net metering work?”

If you’ve been on the receiving end of skyrocketing electricity costs, know that you are not alone.

As adults, we are constantly grappling with a massive amount of bills that just never seem to stop.

Amidst the chaos, something that might have piqued your interest is the talk of green energy solutions.

You’ve heard about solar panels on your neighbor’s roof and wind turbines at your local farm, but the financial logistics and understanding of how these systems might actually save you money may seem like a tangled web.

In the middle of all this, net metering emerges as a glimmer of hope.

This concept not only allows for a transition to a more sustainable energy source but also holds the promise of making your wallet a little heavier.

1. What is Net Metering?

Net metering is a billing mechanism that has gained significant attention in the sustainable energy sphere.

But what exactly is it?

Simply put, net metering is a system that enables solar panel owners to feed unused electricity back into the grid, effectively spinning their electricity meter backward.

Think of an average day when you’re not at home, and your solar panels are diligently soaking up sunlight.

Instead of this excess energy going to waste, net metering steps in, turning your home into a mini power station that supplements the energy grid.

The beauty of net metering lies in its circular model, allowing you to both consume and contribute to the electrical grid.

Popularized due to its dual promise of financial savings and sustainable energy, net metering has seen a surge of interest in recent years.

Homeowners are beginning to see the allure of not just being consumers, but also contributors to their energy source.

What makes it particularly attractive is the fact that it leverages something as commonplace and as potent as sunlight, translating it into something as essential as electricity.

In essence, net metering harnesses the power of nature and uses it to create a more sustainable and financially appealing energy solution.

It offers a refreshing twist to the traditional one-sided consumer relationship we’ve had with the electrical grid.

2. How Does It Work?

In understanding the functioning of net metering, it’s important to first acknowledge that it hinges on one key component: a bi-directional meter.

This device, unlike a traditional meter, is capable of measuring electricity flow in both directions: consumption (electricity flowing from the grid to your house) and generation (electricity flowing from your house to the grid).

The working of net metering revolves around this exchange.

Your solar panels collect sunlight and convert it into electricity, a portion of which is used for your home’s needs.

The good news is that there are bound to be periods of surplus production—days when the sun is particularly generous or times when your consumption is minimal.

In such instances, the excess electricity is fed back into the grid via the bi-directional meter, thereby “storing” it for future use.

So, instead of your meter ticking forward as it usually does, it ticks backward, representing the electricity you are contributing back to the grid.

This backward movement effectively reduces your electricity bill because you are billed only for your ‘net’ energy use, that is, the difference between the energy consumed from the grid and the energy contributed back.

When night falls, or on cloudy days when your solar panels can’t produce enough power, you draw electricity from the grid as you usually would.

The net metering system keeps track of this consumption and, importantly, offsets it against your previously banked surplus electricity.

Hence the term ‘net metering’ – it’s all about the balance between what you consume and what you give back.

Consider this scenario: suppose your solar panels generate 10 kilowatt-hours (kWh) of electricity on a sunny day.

You only use 8 kWh and the remaining 2 kWh is sent back to the grid.

Later in the evening, you consume 3 kWh from the grid.

The bi-directional meter, thus, records a ‘net’ consumption of 1 kWh (3 kWh drawn from the grid minus 2 kWh fed into the grid) for that day.

At the end of the billing period, you are only charged for the net electricity used.

If you have given back more energy than you’ve consumed, you will have a ‘credit’ that can be used in future billing periods.

Some utility companies even pay you for the excess electricity!

Net metering’s beauty lies in its simplicity, turning homeowners into active participants in energy management.

By leveraging periods of low consumption and high production, it creates an energy equilibrium, balancing out the grid’s needs with the homeowner’s solar capacity.

This innovative mechanism thus presents a win-win for everyone, pushing us closer to a sustainable future while offering tangible financial advantages.

3. Why Does Net Metering Exist?

Net metering emerged as a response to two significant challenges: the need to reduce greenhouse gas emissions and the quest to ease the financial burden of electricity costs on households.

The past few decades have seen a growing concern over our reliance on fossil fuels for energy, which accounts for more than 80% of global energy consumption.

These non-renewable resources not only pollute the environment but also contribute to climate change, a pressing global issue.

With the rising urgency to address these problems, the world has been seeking renewable and clean energy solutions.

This is where solar power comes into play, as a source of energy that is not only renewable but also abundantly available.

While solar power offers a greener way to meet our energy needs, there are practical limitations.

The intermittent nature of sunlight and the lack of effective storage solutions often result in excess electricity during peak production times and insufficient supply when sunlight is low or absent.

This is where net metering presents a solution.

By enabling the feed of surplus solar power back into the grid, it tackles the issue of wasted energy, ensuring that every bit of generated solar power is put to use.

The second challenge that net metering addresses is economic in nature.

Energy costs are a significant expense for households, and reducing these costs is an ongoing struggle for many.

Net metering offers a way to alleviate this financial burden.

By crediting homeowners for the excess electricity they feed into the grid, net metering effectively reduces their electricity bills, making solar power not just an environmentally friendly option, but a financially viable one as well.

Bear in mind that while the majority of utility companies do offer credits for your excess energy contributions (depending on your state’s regulations), they typically do not offer cash payments.

This dispels the common misconception that solar power generation can serve as a regular income source.

However, the credit provided by these companies can still prove to be immensely beneficial in offsetting your utility costs.

In sum, the existence of net metering stems from the need to maximize the utilization of renewable energy and create an economically enticing alternative for consumers.

It’s a system designed to make the most out of each ray of sunlight and each dollar in your pocket.

7. FAQs

bulletCan any property implement a net metering system?

While ideally, any property can implement a net metering system, the feasibility greatly depends on several factors.

These include the property’s geographical location, the solar potential, the size and orientation of the roof, and local net metering regulations.

It’s always best to consult with a local solar installer to assess the practicality of setting up a net metering system on your property.

bulletCan net metering credits expire?

The shelf life of your net metering credits is often contingent upon the regulations of your residing state.

In the majority of states, these credits have a rollover mechanism.

This means they can be carried over from one billing period to the next, sometimes even from one year to another.

Consequently, there’s no pressure to consume all your credits within a single billing period.

For example, during the summer, your solar energy system will likely produce excess energy, providing you with a surplus of credits.

These credits can be conveniently used to offset your electricity consumption during winter months when solar generation might decrease.

bulletDoes net metering exclusively apply to solar?

Net metering isn’t solely tied to solar energy, even though it’s definitely the most common.

The eligibility for net metering can extend to other types of decentralized power generation systems, such as wind turbines, provided the specific regulations in your state permit it.

bulletDo I need a special meter for net metering?

Yes, for net metering, a bidirectional or “net” meter is required.

This meter measures the electricity your home consumes and the excess electricity your solar panels send back to the grid.

It moves forward when you use electricity from the grid and spins backward when your system generates excess power.

Your utility company usually installs this meter as part of your interconnection agreement.

bulletCan I go off-grid with net metering?

While net metering allows your solar energy system to work in tandem with the grid, it does not enable complete independence from it.

During times when your solar system isn’t producing sufficient electricity, such as at night or during overcast days, you’ll still draw power from the grid.

So while net metering reduces dependence on the grid, it does not eliminate it entirely.
