Understand net metering before you size the system.
Net metering can be the difference between a solar array that pays for itself in a few years and one that quietly underdelivers. Here's how it actually works, and what to check before you assume it applies to your project.
The policy shapes the system
Net metering policies vary widely – some utilities offer full retail credit for exported energy, others pay a wholesale rate, and some have time-of-use structures. These differences directly affect system sizing, storage integration, and financial payback. We check your utility's policy before we finalize any design.
- ✓ Full net metering – Design for annual production; grid acts as your battery.
- ✓ Reduced credit – Design to maximize self-consumption; consider battery storage.
- ✓ Time-of-use – Optimize array orientation and storage to export during peak hours.
- ✓ No net metering – Self‑consumption and off‑grid solutions become primary design drivers.
What to check for your specific utility
Net metering rules differ by state, utility, and even by rate class. We verify these key parameters for every project:
| Credit rate | Retail, wholesale, or a blend? |
|---|---|
| System size cap | kW limit for eligibility |
| Rollover | Monthly or annual credit expiration? |
| Time‑of‑use | Does the credit vary by hour? |
|---|---|
| Interconnection fee | Upfront costs and timeline |
| Program cap | Is the utility's net‑metering program full? |
Frequently Asked Questions About Net Metering
Answers to what homeowners and property owners most often ask about net metering. Don't see what you need? Reach out directly.
01 What is net metering, and how does it work?
Net metering is a billing program that allows solar panel owners to receive credit for excess electricity their system sends to the electric grid. When your solar panels produce more electricity than your home uses, the extra energy is exported to the utility. Later, when your system isn't producing enough electricity, such as at night, you can use those credits to offset electricity purchased from the grid. Net metering policies vary by utility and state, so compensation rates and program rules may differ.
02 How does net metering reduce my electricity bill?
Net metering lowers your electric bill by giving you credit for excess solar energy produced during the day. Instead of wasting unused electricity, your utility records the exported energy and applies credits to future electricity usage. Depending on your utility's policy, these credits can significantly reduce monthly energy costs and improve the long-term return on investment of your solar system.
03 Is net metering available in every state?
No. Net metering is not available everywhere, and the rules vary by state, utility company, and local regulations. Some utilities offer full retail credit, while others use reduced compensation or net billing programs. Before designing a solar system, it's important to verify your utility's current solar compensation policy.
04 How do I know if my utility company offers net metering?
The easiest way to determine if your utility offers net metering is by reviewing its solar interconnection program or contacting a qualified solar professional. During the design process, we verify your utility's net metering policy, application requirements, export compensation, and system eligibility before finalizing your solar design.
05 Does net metering affect the size of my solar system?
Yes. Net metering directly influences how a solar system should be sized. Utilities with generous export credits often allow homeowners to size systems closer to annual electricity consumption, while reduced compensation programs typically favor systems designed around daytime self-consumption and battery storage.
06 Can I still benefit from solar if my utility has reduced net-metering credits?
Yes. Even if your utility provides lower compensation for exported electricity, solar can still generate significant savings. Many homeowners increase their savings by pairing solar panels with battery storage, shifting energy usage to daylight hours, and optimizing system design based on their utility's rate structure.
07 What happens if my solar panels produce more electricity than I use?
When your solar panels generate more electricity than your home consumes, the excess energy is exported to the electric grid. Depending on your utility's policy, you'll receive energy credits, financial compensation, or bill reductions that can offset future electricity usage.
08 Do unused net-metering credits roll over each month or expire?
It depends on your utility. Some utilities allow credits to roll over month to month and settle annually, while others expire monthly or compensate remaining credits at a lower wholesale rate. Understanding your utility's rollover policy helps maximize the financial value of your solar system.
09 Can I install a battery with a net-metered solar system?
Yes. Battery storage can be installed with most net-metered solar systems. Batteries store excess solar energy produced during the day and supply electricity during the evening, outages, or periods of high utility rates. Many homeowners install batteries to improve energy independence and maximize solar savings.
10 What's the difference between net metering and net billing?
Net metering typically provides energy credits based on electricity exported to the grid, often at or near retail value. Net billing compensates exported electricity at a lower rate while charging the homeowner the full retail price for electricity consumed from the grid. This difference often increases the value of battery storage and self-consumption.
11 How does time-of-use (TOU) billing affect net metering?
Time-of-use rates charge different electricity prices depending on the time of day. During high-demand periods, electricity costs more. Solar systems and batteries can reduce costs by generating or storing electricity before expensive peak-rate hours, improving the financial performance of the system.
12 Can net metering eliminate my electric bill completely?
In some cases, yes. A properly sized solar system under favorable net metering policies can offset most or all annual electricity usage. However, many utilities still charge minimum service fees, grid connection fees, or non-bypassable charges that remain on your monthly bill.
13 Can I add more solar panels to my system later?
Usually, yes. Many solar systems can be expanded later if your electrical equipment, roof space, utility program, and inverter capacity allow. Future additions may require updated utility approval or changes to your existing interconnection agreement.
14 How long does the net-metering approval process take?
Approval times vary by utility but typically range from several days to several weeks after all required documents are submitted. The timeline depends on the utility's review process, permit approvals, inspections, and interconnection requirements.
15 Who submits the net-metering application to the utility company?
Most homeowners have their solar contractor or design company complete and submit the interconnection and net-metering application. This helps ensure all technical documents, electrical plans, permits, and utility requirements are completed accurately.
16 Can my utility deny my net-metering application?
Yes, although denials are uncommon when the system meets all utility requirements. Applications may be delayed or rejected if documentation is incomplete, equipment doesn't meet utility standards, or the proposed system exceeds local program limitations.
17 Does net metering work during a power outage?
No. Standard grid-connected solar systems automatically shut down during utility outages for safety reasons. To continue powering your home during an outage, you'll typically need a battery backup system or another approved backup power solution.
18 Should I install a battery if my utility offers net metering?
It depends on your utility's compensation policy, electricity rates, and personal energy goals. Batteries are especially valuable where export credits are low, electricity prices vary throughout the day, or homeowners want backup power during outages.
19 How do I choose the right solar system size for my home?
The ideal system size depends on your annual electricity usage, roof space, future energy needs, utility policies, and whether you plan to install battery storage or electric vehicles. A professional solar design includes production modeling and utility analysis to determine the optimal system size.
20 Is solar still worth it if my utility no longer offers full net metering?
Yes. Solar remains a smart investment for many homeowners, even under reduced export compensation programs. Modern solar designs focus on maximizing self-consumption, integrating battery storage, and reducing dependence on rising utility electricity rates. Proper system sizing and utility-specific design are key to achieving the best financial results.
