Sarah Johnson from Phoenix, Arizona installed a 7.2 kW solar system on her home in 2024. Thanks to net metering, she’s saving $1,847 annually on her electricity bills – even earning credits during sunny summer months that carry over to winter. Her solar panels produce about 11,500 kWh per year, but her home only uses 9,200 kWh annually. The excess 2,300 kWh flows back to the grid, earning her credits worth $368 each year at Arizona’s retail rate of 15-16 cents per kWh.
Net metering in solar is a billing mechanism that allows homeowners with solar panels to receive credits for excess electricity they generate and send back to the utility grid. Think of it as a virtual battery bank – when your panels produce more energy than you use, the surplus gets “stored” as credits on your utility bill that you can use later when your panels aren’t producing enough power.
In 2025, net metering has become more critical than ever as policy changes sweep across states, grid modernization accelerates, and solar adoption reaches new heights. With 4.4 million American homes now powered by solar, understanding how net metering works can be the difference between a good solar investment and a great one.
In this comprehensive guide, you’ll learn exactly how net metering works, which states offer the best programs, how much you can save, and what policy changes in 2025 mean for your solar investment. Whether you’re considering solar or already have panels installed, this guide will help you maximize your savings and navigate the evolving landscape of solar compensation programs.
What is Net Metering?
Net metering is a utility billing arrangement that allows solar panel owners to receive credit for electricity they generate but don’t immediately use. When your solar panels produce more electricity than your home consumes, the excess power flows back into the utility grid through the same electrical connection that brings power to your home.
The key component that makes net metering possible is a bidirectional meter (also called a net meter). Unlike traditional electric meters that only measure electricity flowing into your home, bidirectional meters can measure electricity flowing in both directions – into your home from the grid and out of your home to the grid.
Here’s how the credit system works:
- Daytime production: Your solar panels generate electricity, powering your home first
- Excess generation: Any surplus electricity automatically flows to the grid
- Credit accumulation: Your utility company tracks this excess and applies credits to your account
- Evening consumption: When your panels aren’t producing, you draw electricity from the grid
- Credit usage: Your accumulated credits offset the cost of grid electricity
Net Metering vs. Other Compensation Programs
It’s important to distinguish net metering from other solar compensation programs:
- Net metering: Typically offers 1:1 credit (one kWh generated = one kWh credit)
- Feed-in tariffs: Pay a fixed rate for all solar production, usually requiring separate meters
- Net billing: Offers credits at wholesale rates, typically lower than retail electricity prices
- Buy-all, sell-all: Utility purchases all solar production while you buy all consumption at standard rates
Key Net Metering Terminology
- Retail rate: The price you normally pay for electricity from your utility
- Wholesale rate: The lower price utilities pay for electricity from power plants
- True-up period: Annual reconciliation of credits and consumption
- Rollover credits: Unused credits that carry forward to future billing periods
- Interconnection: The process of connecting your solar system to the utility grid
How Net Metering Works: Step-by-Step Process
Understanding the day-to-day and month-to-month mechanics of net metering helps you maximize your solar savings. Here’s exactly how the process works from sunrise to your annual bill.
Daytime Solar Production and Excess Generation
During peak sunlight hours (typically 9 AM to 4 PM), your solar panels generate the most electricity. Let’s follow a typical sunny day:
Morning (6 AM – 9 AM): Panels begin producing power, but generation is still relatively low. Your home likely draws some electricity from the grid to meet demand.
Midday (9 AM – 4 PM): Peak production period. A typical 6 kW system might generate 30-40 kWh during these hours, while your home may only use 15-20 kWh. The excess 15-20 kWh flows back to the grid, spinning your meter backward and earning credits.
Late afternoon (4 PM – 7 PM): Production decreases but may still exceed consumption, especially if you’re not home during the day.
Evening and Nighttime Grid Consumption
When the sun sets, your panels stop producing electricity, but your home’s energy needs continue:
- Your home automatically draws electricity from the grid
- The bidirectional meter measures this consumption
- Your utility applies the daytime credits against nighttime usage
- You only pay for the “net” difference between what you produced and consumed
Monthly Billing Cycle Explanation
At the end of each billing period, your utility calculates your net usage:
Scenario 1 – Net Credit: If you generated more than you consumed, you receive a credit balance that rolls over to next month.
Scenario 2 – Net Usage: If you consumed more than you generated, you pay for the difference at your regular electricity rate.
Scenario 3 – Net Zero: If generation equals consumption, you typically pay only basic connection fees (usually $10-30/month).
Annual True-Up Process
Most net metering programs include an annual “true-up” reconciliation:
- Credit review: Utility examines your 12-month credit balance
- Excess handling: Policies vary on what happens to surplus annual credits
- Payment options: Some utilities pay cash for excess, others forfeit unused credits
- Reset period: Your credit balance typically resets to zero after true-up
Real-World Example with Actual Numbers
Let’s examine the Martinez family’s net metering experience in California with a 8.5 kW solar system:
System specifications:
- 8.5 kW solar array
- Annual production: 12,750 kWh
- Annual consumption: 11,200 kWh
- Utility rate: $0.28/kWh
Monthly breakdown (July):
- Solar production: 1,340 kWh
- Home consumption: 980 kWh
- Excess to grid: 360 kWh
- Credits earned: 360 kWh × $0.28 = $100.80
Monthly breakdown (December):
- Solar production: 680 kWh
- Home consumption: 1,150 kWh
- Grid consumption: 470 kWh
- Credits used: 470 kWh × $0.28 = $131.60
Annual savings: The Martinez family saves approximately $3,164 annually through net metering, with 1,550 kWh of excess credits that roll over each year.
Types of Net Metering Programs
Not all net metering programs are created equal. Understanding the different types helps you evaluate what’s available in your area and set realistic expectations for your solar investment.
True/1-to-1 Net Metering
This is the most favorable type of net metering for solar customers:
- Credit value: Full retail rate for excess electricity
- Ratio: 1 kWh generated = 1 kWh credit
- Availability: Available in about 20 states as of 2025
- Benefits: Maximum financial return on solar investment
States with true net metering include Nevada, New Mexico, and many northeastern states. These programs offer the fastest payback periods for solar installations.
Net Billing Programs
Net billing is becoming more common as utilities seek to reduce compensation rates:
- Credit value: Wholesale or avoided-cost rate (typically 30-70% of retail)
- Structure: You “sell” excess power at wholesale, buy consumption at retail
- Impact: Longer payback periods but still economically viable
- Examples: California’s NEM 3.0, Hawaii’s Customer Grid Supply Plus
Buy-All, Sell-All Arrangements
This structure separates your solar production from your consumption entirely:
- Production: Utility purchases 100% of your solar generation
- Consumption: You purchase 100% of your electricity needs at retail rates
- Metering: Requires two separate meters
- Rates: Solar compensation typically below retail rates
Virtual Net Metering (Community Solar)
Virtual net metering allows participation without rooftop installation:
- Structure: Subscribe to a portion of a community solar farm
- Credits: Receive credits based on your subscription’s production
- Savings: Typically 5-20% discount on electricity costs
- Accessibility: Available to renters and homes unsuitable for solar
Time-of-Use Net Metering
Some programs incorporate time-based pricing:
- Variable credits: Credit value changes based on time of day
- Peak hours: Higher credit rates during peak demand periods
- Off-peak hours: Lower credit rates during low demand periods
- Complexity: Requires understanding of utility rate schedules
Benefits of Net Metering
Net metering provides substantial benefits not just for solar customers, but for the electrical grid and environment as a whole. Understanding these advantages helps explain why net metering has been such a successful policy for promoting renewable energy adoption.
Financial Benefits with ROI Calculations
The primary benefit of net metering is the enhanced financial return on your solar investment:
Increased savings potential: Net metering can increase your annual solar savings by 20-50% compared to self-consumption only. For a typical 6 kW system producing 9,000 kWh annually:
- Without net metering: Save on ~60% of production (5,400 kWh)
- With net metering: Save on 100% of production (9,000 kWh)
- Additional annual savings: $500-800 in most markets
Faster payback periods: Net metering typically reduces solar payback periods by 2-4 years. A $18,000 solar system might have:
- Payback without net metering: 12-15 years
- Payback with net metering: 8-11 years
- Lifetime savings increase: $8,000-15,000
Higher return on investment: Net metering can boost solar ROI from 6-8% to 10-15% annually, making solar competitive with many other investments.
Grid Stability and Infrastructure Benefits
Net metering provides valuable services to the electrical grid:
Reduced peak demand: Solar production peaks during high-demand afternoon hours, reducing strain on the grid when electricity is most expensive to generate.
Distributed generation benefits: Local solar production reduces the need for long-distance electricity transmission, decreasing line losses and infrastructure wear.
Grid resilience: Distributed solar resources provide backup generation capacity and can help maintain local power during grid disturbances.
Deferred infrastructure investments: Studies show that distributed solar can delay the need for new power plants and transmission lines, saving utilities billions in capital expenses.
Environmental Impact
Net metering accelerates environmental benefits by making solar more economically attractive:
- Carbon reduction: Each net-metered solar system avoids 3-4 tons of CO2 annually
- Air quality: Reduced fossil fuel generation improves local air quality
- Water conservation: Solar requires no water for generation, unlike fossil fuel plants
- Accelerated adoption: Better economics drive faster renewable energy deployment
Energy Independence Advantages
Net metering enhances energy security at multiple levels:
- Household level: Reduced dependence on utility electricity and protection from rate increases

Limitations and Drawbacks
While net metering offers significant benefits, it’s important to understand the limitations and potential drawbacks that can affect your solar investment returns.
Credit Rollover Restrictions
Most net metering programs have limitations on how long you can keep accumulated credits:
Monthly rollover limits: Some programs only allow credits to roll over for 1-3 months, meaning unused summer credits might expire before winter when you need them most.
Annual true-up policies: Many utilities reset your credit balance to zero each year, potentially forfeiting thousands of dollars in excess production. For example, if you generate $500 worth of excess credits annually, you might lose this value under annual true-up rules.
Credit expiration: Some programs allow credits to expire after 12-24 months, penalizing customers whose systems are sized to generate more than their annual consumption.
Reduced Compensation Rates
The trend toward lower net metering compensation is accelerating:
Wholesale rate compensation: Many new programs pay only 3-7 cents per kWh for excess generation, while retail rates are 10-30 cents per kWh. This can reduce your solar savings by 40-70%.
Time-of-use complications: Some programs credit excess generation at off-peak rates (when solar produces most) but charge consumption at peak rates (when you use most electricity), creating an unfavorable arbitrage.
Declining rate schedules: Programs like California’s NEM 3.0 include declining compensation rates over time, reducing long-term investment returns.
System Size Limitations
Net metering programs often cap the size of eligible systems:
- Residential caps: Typically 10-25 kW for residential systems
- Percentage limits: Some programs limit system size to 100-120% of annual consumption
- Aggregate caps: Utilities may stop accepting new net metering customers once total capacity reaches 1-5% of peak demand
Utility Connection Fees
Even with net metering, you’ll still pay certain utility charges:
- Monthly connection fees: $10-50/month regardless of usage
- Demand charges: Some utilities add demand charges for solar customers
- Grid access fees: Special fees for maintaining grid connection
- Standby charges: Fees for having backup grid service available
Policy Uncertainty and Changes
The regulatory landscape for net metering is rapidly evolving:
Grandfathering concerns: While most programs grandfather existing customers, policy changes can affect system expansions or new installations.
Utility rate redesign: Utilities are implementing new rate structures that can reduce net metering benefits, such as higher fixed charges and lower energy rates.
Political risk: Net metering policies can change with new administrations or regulatory appointees, creating long-term uncertainty for solar investments.

Frequently Asked Questions
How much money can I save with net metering?
Savings depend on your location, electricity rates, and solar system size. Typical homeowners save $1,000-2,500 annually with net metering. For example, a 6 kW system in a state with 15-cent electricity and full retail net metering might save $1,800/year, while the same system with reduced-rate net billing might save $1,200/year.
Do I need special equipment for net metering?
Your utility will install a bidirectional net meter at no cost. Your solar system needs a grid-tie inverter that meets utility interconnection standards. Most modern solar installations include all necessary equipment for net metering participation.
What happens to my credits if I move?
Net metering credits typically don’t transfer to new owners or locations. However, credits usually increase your home’s value, and new owners can continue participating in net metering. Some utilities allow credit transfers within their service territory.
Can I participate in net metering if I rent my home?
Traditional net metering requires system ownership, which typically means homeownership. However, community solar programs with virtual net metering are available to renters in many areas, offering 5-20% savings on electricity bills.
How long do net metering credits last?
Credit duration varies by program. Some allow indefinite rollover, others expire credits monthly or annually. Most programs include annual “true-up” periods where excess credits are either paid out, rolled over, or forfeited.
Is net metering available everywhere?
Net metering is available in 34 states plus Washington, D.C. as of 2025. Alabama, South Dakota, and Tennessee lack statewide programs. Even where available, specific terms vary significantly by utility company.
Will net metering policies change in the future?
Yes, many states are modifying net metering policies. The trend is toward reduced compensation rates, but existing customers are typically grandfathered under current terms for 10-20 years. New installations may face different terms.
Can I add batteries to my net metering system later?
Yes, batteries can typically be added to existing net metered systems. This may require utility notification and potentially modify your net metering arrangement. Some utilities offer enhanced programs for solar-plus-storage systems.
Do I still pay utility bills with net metering?
Yes, you’ll still receive monthly utility bills that show your net usage. Even if your net usage is zero, you’ll typically pay connection fees of $10-50/month. Bills will show both electricity consumed from the grid and excess electricity sent to the grid.
How does net metering work during power outages?
Standard net metered systems shut down during outages for safety reasons. Your solar panels won’t power your home during outages unless you have battery backup. The system automatically reconnects when grid power is restored.
Can I sell excess electricity back to the utility for cash?
Most net metering programs provide bill credits rather than cash payments. Some utilities pay for annual excess generation, but rates are typically at wholesale prices (much lower than retail rates). The primary benefit is offsetting your electricity consumption.
How accurate are net meters?
Net meters are highly accurate, typically within 1-2% of actual energy flow. They’re tested and certified by utilities and meet strict accuracy standards. Digital meters provide detailed data on both energy consumption and production.
What size solar system is best for net metering?
Optimal system size typically matches 90-110% of your annual electricity consumption. Oversizing can result in forfeited credits under annual true-up policies. Your installer can analyze your usage patterns and utility policies to recommend the best size.
Does net metering work with all types of solar panels?
Net metering works with any grid-tied solar system, regardless of panel type (monocrystalline, polycrystalline, or thin-film). The key requirement is a grid-tie inverter that meets utility interconnection standards.
How long does it take to get approved for net metering?
Interconnection approval typically takes 15-45 days for residential systems. Complex installations or utility backlogs can extend this timeline. Your installer should handle all paperwork and coordinate with the utility throughout the process.
