Net metering is one of the most important concepts for solar homeowners to understand. When your solar panels produce more electricity than your home is using, that excess energy flows to the utility grid and net metering ensures you receive credit for it.
Rather than wasting surplus production, net metering turns your solar system into a two-way exchange with your utility. You send power out during peak production and draw credits back when you need them. For most homeowners in Pennsylvania, New Jersey, and Delaware, net metering is a key reason solar delivers strong financial returns.
How Net Metering Works
Net metering creates a rolling energy balance between your home and the utility grid.
During daylight hours, your solar panels may produce more electricity than your household needs. Instead of losing that energy, it flows back to the grid. Your utility tracks this exchange using a bi-directional meter.
For every kilowatt-hour (kWh) your system exports, you earn a credit. Later, at night, during cloudy days, or in winter months — you use those credits to offset the electricity you pull from the grid.
At the end of each billing cycle, your utility calculates the “net” difference between energy produced and energy consumed. If production exceeds usage, credits typically roll forward to the next month.
This system ensures every kWh your panels generate contributes to savings, even when you’re asleep or away from home.
Key Benefits of Net Metering for Solar Homeowners
Maximizes system value. Without net metering, excess daytime production would have limited use. Net metering ensures you capture full value from every kWh.
Reduces utility bills significantly. By offsetting grid electricity with solar credits, many homeowners see dramatically lower monthly bills and some achieve near-zero electric charges outside of basic service fees.
Provides seasonal flexibility. Summer overproduction builds credits you can use during shorter winter days when solar output naturally dips.
Supports cleaner energy. When you export solar energy to the grid, it reduces the need for fossil-fuel generation in your community.
Net Metering in Pennsylvania, New Jersey, and Delaware
Net metering policies are set at the state level and administered by local utilities, so rules and timelines vary by location.
New Jersey Net Metering
New Jersey offers net metering at a 1:1 retail rate for most residential solar systems. This means you receive full retail value for every kWh you export, the same rate you’d pay to buy that electricity from the grid.
Credits roll forward month to month. At the end of the annual billing cycle, utilities like PSE&G, JCP&L, and Atlantic City Electric reconcile remaining credits according to state rules.
New Jersey’s net metering program is among the strongest in the region, making solar particularly attractive for NJ homeowners.
Pennsylvania Net Metering
Pennsylvania utilities, including PECO, PPL, and FirstEnergy, provide retail-rate net metering credits with flexible rollover options. Credits accumulate month to month and can offset future usage.
Policies vary slightly between utilities, but the core benefit remains: excess solar production earns credits that reduce your annual electricity costs.
Delaware Net Metering
Delaware homeowners served by Delmarva Power can participate in net metering with retail-rate credits. The program allows credits to roll forward monthly, with annual reconciliation options that vary by utility agreement.
Delaware’s net metering rules support straightforward solar economics for residential systems.
What Your Utility Bill Looks Like With Net Metering
After net metering is active, your utility bill will look different than before solar.
Most bills include:
- Total energy consumed — electricity pulled from the grid
- Energy exported — kWh sent back to the grid
- Credits earned or applied — net metering credits offsetting your charges
- Service fees — a modest monthly charge for grid access (typically $10–$20)
If your system produces more energy than you use in a billing cycle, credits carry forward. You won’t receive a check for overproduction in most cases, but those credits reduce future bills.
Some utilities perform an annual “true-up,” reconciling any remaining credits at the end of your billing year. Understanding your utility’s specific process helps you track savings accurately.
Net Metering and Battery Storage
Net metering requires a grid connection. During a power outage, standard grid-tied solar systems shut down automatically for safety even if the sun is shining.
Homeowners who want power during outages pair solar with battery storage. Batteries store excess energy instead of (or in addition to) sending it to the grid, providing backup power when grid electricity isn’t available.
Batteries don’t replace net metering — they complement it. You can still earn net metering credits while also having stored energy available for outages or peak-rate periods.
For homeowners on time-of-use rate plans with PECO or PSE&G, batteries add another layer of value by letting you use stored solar energy during expensive peak hours rather than drawing from the grid.

Frequently Asked Questions
Will I still receive a utility bill with net metering?
Yes. You’ll still receive a monthly bill showing service fees, energy usage, and any credits earned or applied from your solar production.
Do net metering credits expire?
Most programs allow credits to roll over month to month. Some utilities perform annual reconciliations where remaining credits may be paid out at a reduced rate or reset, depending on state policy.
Does net metering work during power outages?
No. Grid-tied solar systems automatically shut down during outages for safety. Battery storage is required to maintain power when the grid is down.
How does net metering work in New Jersey?
New Jersey offers net metering at a 1:1 retail rate for most residential solar systems. Credits roll forward month to month and are reconciled annually by the utility.
Can I cash out my net metering credits?
In most cases, credits are applied to future bills rather than paid out as cash. Some utilities offer annual payouts for excess credits at wholesale rates, but policies vary.
