Net Metering: Maximizing Your Solar Energy Savings
Net metering helps homeowners with solar panels lower their electricity bills by providing credits for excess power sent back to the grid. This article will show you how it works, the benefits, and the policies that can maximize your savings.
Key Takeaways
Net metering allows homeowners with solar panels to earn credits for excess electricity exported to the grid, significantly reducing their electric bills.
Different net metering policies, including virtual and aggregate net metering, cater to varying customer needs and setups, enhancing benefits for solar energy users.
Understanding net metering caps, limitations, and state incentives is crucial for maximizing your solar investment and ensuring continued access to net metering benefits.
Understanding Net Metering
Net metering is a system designed to compensate homeowners with solar panels for the electricity they produce. Here’s how it works:
When your solar panels generate more power than you consume during the day, the excess electricity is sent back to the grid.
Your electric meter runs backward, effectively reducing your overall electricity usage.
You earn credits on your electric bill for the excess electricity sent to the grid.
These credits can offset your electricity consumption during times when your panels aren’t producing enough power, such as at night or on cloudy days.
The essence of net metering lies in the concept of net energy consumption, which is the difference between the total electricity consumed and the total electricity generated by your solar system. If your solar panels produce more electricity than you use, you get a negative bill credit that can carry over to the next month. This means that not only are you reducing your reliance on the grid, but you are also being financially rewarded for your contribution to the renewable energy supply, while managing any excess energy.
Net metering is widely adopted, with over 30 states, including Massachusetts and Connecticut, having mandatory net metering policies in place. These policies vary by state but generally provide significant benefits to solar energy users, encouraging more homeowners to invest in solar energy systems.
Knowing how net metering operates is key to achieving maximum savings and optimizing your solar energy investment.
How Solar Panels Produce and Export Electricity
Solar panels convert sunlight into electricity using photovoltaic cells:
When sunlight hits these cells, it creates an electric field that generates electricity.
This electricity is then used to power your home.
Any excess electricity is exported to the grid.
Solar panels generate electricity during daylight hours, often producing more energy than the household consumes during these times. Additionally, solar electricity can be harnessed to maximize efficiency.
The electricity produced by your solar panels is valued equally to the electricity you receive from the utility. This means that for every kilowatt-hour (kWh) of solar energy you export to the grid, you receive a one-to-one credit on your electric bill. Most solar customers use the majority of their own generated power, but a significant fraction of energy produced is still exported to the grid, especially during peak sunlight hours.
This system not only helps you reduce your electricity bills but also supports the stability of the electric grid by supplying renewable energy. By generating your own electricity, you are less dependent on the grid, and you contribute to a more sustainable energy future. Grasping how solar panels generate and export electricity helps you appreciate the advantages of solar net metering.
Types of Net Metering Policies
There are several types of net metering policies that cater to different solar energy setups and customer needs. The most common arrangement involves a single meter on a single property, which provides credits to one electric bill. This straightforward setup is ideal for individual homeowners with solar panels installed on their property.
Virtual net metering is another important net metering policy, particularly for community solar projects. This policy allows participants to benefit from solar energy generation even if the solar panels are not installed on their property. Instead, the electricity generated by a remote solar array is credited to the participants’ electric bills proportionally to their share of the generated solar energy. Currently, fewer than 20 states have implemented virtual net metering policies.
Aggregate net metering is designed for larger projects, allowing multiple meters to be combined for a single solar energy system. This policy is beneficial for farms, campuses, or municipalities that have multiple buildings and meters. Legislative actions in states like Massachusetts highlight the focus on enhancing net metering policies to support distributed solar energy generation.
Familiarity with various net metering policies aids in selecting the optimal setup for your solar energy system, thereby maximizing your benefits.
Net Metering Caps and Limitations
Many states have introduced caps on net metering to limit the total amount of energy that can be credited through the program. Once a net metering cap is reached, utilities may halt new enrollments until capacity is expanded or new policies are introduced. These caps are typically based on the total generation per electric company territory and can impact the availability of net metering for new solar customers.
The specifics of net metering caps and their enforcement vary across states, with some states actively exploring adjustments to encourage greater adoption of solar energy. In Massachusetts, the cap has been raised for residential systems under 25 kW AC, allowing more homeowners to take advantage of net metering benefits and expand access to clean solar power.
Knowing these caps and limitations is vital for planning your solar energy investment and ensuring full benefits from net metering programs.
Calculating Net Metering Credits
Calculating net metering credits involves:
Determining your net monthly consumption, which is the total electricity consumed minus the total electricity generated by your solar system.
If your net consumption is positive, you are billed for the excess usage at the end of the billing period.
If you generate more electricity than you consume, you earn net metering credits that can be carried over to future billing periods.
These credits do not have an expiration date, allowing you to accumulate them over time. It’s important to note that certain fixed charges and system benefit charges are excluded from the net metering credit calculations.
The value of these credits can also vary based on your rate class and the specific policies of your electric company. Learning to calculate and maximize your net metering credits is crucial for optimizing your solar energy savings.
Interconnection Requirements
Interconnection is the process of connecting your solar array to the utility grid. To do this, customer-generators must have interconnection agreements with their electric distribution company. These agreements detail the technical specifications and safety requirements necessary for connecting your solar system to the grid.
The interconnection process involves multiple review levels based on the size of the generator and other factors. The steps include:
After your solar system is installed, it must be inspected by the local jurisdiction.
A request for interconnection is submitted.
Utility approval is mandatory before installation, a process that companies like Insight Energy can do for you.
Being aware of these requirements ensures your solar system connects smoothly and safely to the grid.
State Incentives for Net Metering
Many states offer various incentives for solar energy and net metering. For instance, Massachusetts has several programs designed to promote solar energy adoption and provide financial benefits for solar customers. To find local net metering policies and incentives, the DSIRE database is a useful tool that allows you to filter by state.
For specific net metering inquiries, you can visit the contact page of your utility company, and companies like Insight Energy are available to guide you through the process. For further information, leveraging state incentives can significantly enhance the financial benefits of your solar energy system.
Impact of Net Metering on Electric Bills
Net metering allows customers to:
Sell excess solar energy back to the grid, providing credits that can offset future electricity use.
Apply these credits to both delivery and supply charges, potentially reducing your electric bill to zero.
Benefit from many utilities crediting excess generation at the full retail rate, making net metering highly beneficial for solar customers.
Deciphering your electric bill and the application of net metering credits is crucial for maximizing savings. Insight Energy helps utility customers navigate their electric bills and optimize their net metering benefits.
By effectively using net energy metering, you can significantly reduce your electricity costs and contribute to a more sustainable energy use future, especially with surplus electricity.
What Happens To Unused Credits Earned?
One common question about net metering is what happens to your unused credits. Here’s how it works:
Unused credits do not expire. They roll over month to month and keep accumulating as long as your account stays active.
If a customer’s account is closed, these credits are not eligible for cash out.
Credits can be transferred to other electric accounts if a Schedule Z is submitted before closing the account.
For customers on time-of-use (TOU) rates, credits are earned according to the utility’s TOU pricing structure — meaning the value of your credits depends on when your system produces and when you use electricity. Currently, Massachusetts and Connecticut don’t use TOU rates for residential customers, but they will eventually.

Frequently Asked Questions
What are the cons to net metering?
Net metering can pose several challenges, such as a lack of direct financial payments, ongoing dependency on the grid, and potential infrastructure costs. Additionally, it may not always align energy production with demand, leading to policy and rate structure uncertainties.
Do net metering credits expire?
Net metering credits do not expire in Massachusetts and Connecticut.
Can I transfer my net metering credits if I close my account?
Yes, you can transfer your net metering credits to other electric accounts by submitting a Schedule Z before closing your account.
How are net metering credits calculated for time-of-use rates?
Net metering with time‑of‑use rates is more complex than standard billing because your solar production and energy use are valued differently depending on the time of day. You typically earn credits when your system produces power during lower‑rate periods (like midday) and use electricity during higher‑rate periods (late afternoon and evening) when solar production slows. As a result, even if you produce as much energy as you consume overall, your savings depend on when that energy is generated versus when you use it.
