If you’ve ever watched your electric bill shrink after installing solar panels, chances are net metering had a hand in it. For years, this system helped homeowners make solar more affordable by crediting them for the excess electricity their systems produced. But in 2025, changes to net metering policies are beginning to take shape—and if you’re considering solar, already have it, or are simply curious about energy trends, you’ll want to know how these updates could affect your bottom line.
Let’s break down what’s happening, what it means for your wallet, and how to make smart energy decisions moving forward.
What Is Net Metering and Why Does It Matter?
A Quick Refresher on Net Metering
Net metering, or Net Energy Metering (NEM), is a billing system that credits homeowners for the extra solar power they send back to the electric grid. Let’s say your panels produce more electricity than your home uses during the day. With net metering, your utility tracks that surplus and subtracts it from your usage when you’re pulling energy from the grid at night. The result? A lower electric bill.
Why Net Metering Has Been Crucial for Solar Adoption
Net metering has been one of the most important incentives for homeowners to switch to solar. It’s helped lower upfront payback periods and made solar systems far more cost-effective over time. Beyond financial perks, it’s also benefited the environment by reducing reliance on fossil fuels and helped utilities manage daytime demand more efficiently.
In short, net metering has allowed thousands of families to become mini power producers—and get rewarded for it.
How Net Metering Worked Before 2025
The Full Retail Credit Model
Before 2025, many net metering programs credited homeowners at the full retail rate for each kilowatt-hour (kWh) of electricity they exported to the grid. So if you paid 16 cents per kWh when using energy, you’d get that same amount credited when you sent solar power back. This one-to-one credit made it possible for some homeowners to wipe out their power bills almost entirely.
Regional Variations in Policy
Net metering policies weren’t universal, though. In the U.S., 38 states and Washington, D.C., had formal net metering laws, but some major cities—like Austin and San Antonio—offered it voluntarily. Meanwhile, other states like South Dakota and Tennessee had little to no net metering in place at all. Your savings potential often depended more on your ZIP code than your solar panel quality.
What’s Changing in Net Metering in 2025?
Shift from Full Retail to Feed-In Tariff Models
The biggest change happening in 2025 is a growing shift away from full retail credits. More utilities are moving toward what’s called a “feed-in tariff” model. Instead of getting the same rate for your solar exports as you pay for consumption, you now might earn a lower rate, more aligned with the utility’s wholesale cost of electricity.
For example, while you may still pay 16 cents per kWh for the energy you use, your utility might only credit you 10 cents per kWh for the energy you send back. The idea is to reduce what some utilities call the “cost shift” to non-solar customers, but for homeowners, it means fewer savings.
Time-of-Use and Expiration Policies
Another change? How your credits roll over. Many utilities used to let you carry over unused credits month-to-month, and in some cases, year-to-year. But now, some are introducing expiration dates. If you don’t use those credits by a certain time—often the end of the year—they could disappear.
If your utility lets you choose an expiration date, consider setting it after winter. This way, you can accumulate credits during sunny summer months and use them when your solar production dips during the colder season.
Utility-Specific Policy Adjustments
What makes this even trickier is that changes aren’t the same everywhere. Some utilities are adopting changes quickly. Others are rolling out pilot programs or offering hybrid options. That’s why checking with your local utility or reviewing your state’s policies through the DSIRE database is critical. Even within the same state, two households in different utility territories might face very different net metering rules.
How These Changes Affect Homeowners
Impact on Monthly Electric Bills
The biggest shift is in the savings. If you’re getting credited less for the energy you export, your electric bill might not shrink as much as it would have under older policies. Homeowners who went solar under full-retail credit programs may still be grandfathered in, but new customers will feel the difference.
This is why system sizing matters now more than ever. Installing a solar system that produces far more electricity than you use won’t help you. Instead of rolling over valuable credits, you might lose them altogether if they expire.
Effect on Payback Period and ROI
Naturally, reduced credits stretch out the time it takes to recoup your solar investment. A system that once had a 7–8-year payback period could now take 10 years or more. But that doesn’t mean solar isn’t worth it anymore. Energy prices continue to rise, and once your system is paid off, your power is essentially free.
What’s different is the strategy. You’ll want to be more deliberate in choosing your system size, installation timing, and utility plan.
What to Consider Before Installing Solar in 2025
If you’re just starting your solar journey, here are a few steps to take:
-
Check local NEM rules: Policies vary widely, and knowing yours is key.
-
Ask your installer about credit rates: Make sure any savings estimate includes updated net metering terms.
-
Think about adding battery storage: With lower export credit rates, storing excess energy for evening use might make more financial sense than feeding it back into the grid.
Tips to Maximize Your Savings Under New NEM Rules
Even with the changes, there are smart ways to get the most from your solar investment:
-
Size your system to your usage, not your roof’s full capacity. Bigger isn’t always better when the excess energy isn’t fully credited.
-
Consider battery storage to avoid losing value on unused credits, especially if your utility has an expiration policy.
-
Use energy-intensive appliances during daylight hours when your panels are actively producing.
-
Choose a time-of-use rate plan (if available) that rewards you for off-peak consumption.
-
Track your system performance regularly, especially through seasonal shifts.
Other Incentives Still Available in 2025
Federal Solar Tax Credit
Thankfully, not everything is changing. The federal solar tax credit remains one of the strongest incentives for going solar. It allows you to deduct 30% of your solar installation cost from your federal taxes. So if your system costs $15,000, you could claim $4,500 back.
This credit is available in every state and can significantly offset the impact of reduced net metering returns.
Local Rebates and State Programs
Many states and cities also offer additional incentives, ranging from cash rebates to performance-based bonuses. A good place to start your research is the Database of State Incentives for Renewables & Efficiency (DSIRE). Or just ask your installer—they’re often plugged into all available local perks.
Is Net Metering Still Worth It in 2025?
In a word—yes. Net metering may not be as generous as it once was, but the value of producing your energy hasn’t gone away. With thoughtful planning, homeowners can still enjoy meaningful savings, increased home value, and the peace of mind that comes with energy independence.
Just think of it like this: you’re not just saving money—you’re investing in cleaner air, a more resilient power grid, and a better future.
Frequently Asked Questions (FAQs)
Is net metering going away in 2025?
Not entirely. It’s changing in many places—mainly shifting from full retail credit to lower rates—but it still exists in most states.
Can I make money with net metering?
No. Utilities won’t pay you cash for your excess energy. You’ll receive credits toward your electric bill, which helps reduce what you owe.
What if I produce more energy than I use?
You’ll get credits, but depending on your utility, those credits might expire if you don’t use them within a certain time frame.
Should I add battery storage with solar now?
Yes, especially if your utility has stopped offering full retail credit. Batteries can help you store and use your power when it’s most valuable.
What’s the best system size under the new NEM rules?
Aim for a system that meets (but doesn’t exceed) your annual electricity usage. Oversizing can lead to wasted credits.
Do NEM changes apply to existing systems?
Usually not. Most existing customers are “grandfathered in” under the terms of their original contract for several years.
Net metering in 2025 may look different than before, but it’s still a core part of the clean energy conversation. With the right strategy, homeowners can still save big while doing good.
