What Is Net Metering?
Net metering is a billing arrangement that allows solar panel owners to receive credit for excess electricity they send back to the grid. When your solar panels produce more energy than your home uses — typically during midday when production peaks — the surplus flows back to the utility grid, and your meter effectively "runs backward."
At the end of each billing cycle, you only pay for the net energy consumed: total electricity used minus total electricity produced. If you produced more than you used, you receive a credit that rolls forward to future bills.
How Net Metering Works in Practice
Here's a typical daily cycle for a net-metered solar home:
- Morning (6-9 AM): Solar panels begin producing. Production is less than consumption, so you draw from the grid.
- Midday (9 AM - 4 PM): Peak solar production exceeds home consumption. Excess energy flows to the grid, earning you credits.
- Evening (4-10 PM): Solar production drops. You consume electricity from the grid, using your accumulated credits.
- Night (10 PM - 6 AM): No solar production. Grid power consumed against your credit balance.
This daily give-and-take means your solar system doesn't need battery storage to be financially viable — the grid itself acts as your "battery," storing your excess production as bill credits.
Types of Net Metering Compensation
Not all net metering programs are equal. The compensation rate you receive for exported energy varies significantly:
Full Retail Rate Net Metering
You receive credit at the same rate you pay for electricity. If you pay $0.15/kWh, your exported solar energy is credited at $0.15/kWh. This is the most favorable arrangement and is available in states like New York, New Jersey, and Massachusetts.
Avoided Cost / Wholesale Rate
You receive credit at the utility's wholesale cost of electricity, typically $0.03-$0.06/kWh — far less than the retail rate. States like Indiana and some utilities in the Southeast use this structure.
Net Billing (NEM 3.0)
California's NEM 3.0 policy, effective since 2023, compensates solar exports at a variable rate based on the time of day and grid demand. Typical compensation ranges from $0.04-$0.08/kWh for midday exports — a 75% reduction from the previous retail-rate program.
Time-of-Use Net Metering
Credits are valued based on when you export. Electricity exported during peak demand hours earns higher credits than off-peak exports. This incentivizes battery storage to shift exports to high-value periods.
State-by-State Net Metering Landscape
Net metering policies vary widely across the United States:
- States with full retail rate: NY, NJ, MA, CT, OR, MD, VT, NH, ME, RI
- States with reduced or tiered rates: CA (NEM 3.0), NV, AZ, IN, MI
- States with no mandatory net metering: AL, TN, MS, SD
- States with net metering under review: FL, NC, SC, GA
Check your state's specific policy to see current net metering rates and any pending changes.
How Net Metering Affects Solar ROI
The compensation rate directly impacts your solar savings and payback period:
- Full retail rate: Maximizes savings. A 10 kW system in NJ might save $2,400/year.
- Avoided cost rate: Reduces savings by 40-60%. The same system might save $1,200/year.
- NEM 3.0 (net billing): Makes battery storage essential to maximize value. Without batteries, savings drop significantly.
What to Do If Your State Has Poor Net Metering
If your utility offers low export compensation, consider these strategies:
- Add battery storage to consume more of your own production and reduce grid exports
- Right-size your system to match your daytime consumption rather than over-producing
- Shift heavy loads (EV charging, laundry, dishwasher) to peak solar production hours
- Monitor time-of-use rates and export during highest-value windows
Despite net metering changes in some states, solar remains financially compelling across most of the country. The federal 30% tax credit, declining panel costs, and rising electricity rates continue to drive positive ROI.
