Puget Sound Energy Net Metering: How to Apply and Get Credited

By Claire Whitaker

Puget Sound Energy net metering lets a home with solar panels send surplus electricity to the grid and receive bill credits for it, which offset the power you draw at night or on cloudy days. This guide walks you through eligibility, the application process, the equipment and paperwork you will need, and how the credits are applied to your account. By the end, you will know what to submit, what to expect from the utility, and where homeowners most often get stuck.

Note that rules, rate schedules and interconnection procedures change over time. Treat this article as a planning guide and confirm current requirements directly with Puget Sound Energy (PSE) before you buy equipment. For electrical work, consult a licensed electrician and your utility’s interconnection staff.

What Puget Sound Energy Net Metering Covers

Net metering is a billing arrangement, not a separate piece of hardware. Your solar system is connected to your home’s electrical panel through a grid-tied inverter. When panels produce more than the house uses, the excess flows onto the utility line, and the meter runs backward. When the house needs more than the panels produce, power is drawn from the grid as usual. Over a billing period, the utility nets these flows together and bills you only for the net consumption.

For a deeper explanation of the electrical side, including anti-islanding protection and what happens during an outage, see How Grid-Tied Solar Works: Net Metering, Interconnection and Outages. That article explains why a grid-tied system shuts down when the grid goes dark, which surprises many first-time owners.

Step 1: Confirm Your Eligibility

Before you start paperwork, check the basic conditions that most utilities apply to residential net metering:

• Your home is served by PSE for electricity at the service address where the system will be installed.
• The system is intended primarily to offset your own consumption, not to operate as a commercial generating facility.
• The system size falls within the residential limit set by the utility and state rules. Systems above the threshold may be routed through a different interconnection track with more study and fees.
• The inverter and other equipment are certified to the relevant safety standards, typically UL 1741 for inverters, and the installation meets the National Electrical Code as adopted locally.

Confirm these points against PSE’s current published guidance, since size limits and eligibility language are updated periodically.

Step 2: Gather Your Documents and Specifications

Interconnection applications stall most often because the paperwork is incomplete. Have these ready before you submit:

1. Your PSE account number and the service address.
2. A single-line diagram showing the panels, string layout, inverter, disconnect switches, main service panel, meter and point of interconnection.
3. The nameplate ratings of every panel and the inverter, including total DC capacity in kilowatts and total AC output of the inverter.
4. The make and model numbers of the inverter and any battery storage, with certification listings.
5. A site plan or photo showing the array location and the utility meter.
6. The name and license number of the installing contractor, if you use one.

Ask your installer to prepare the diagram. A clear, accurate single-line diagram often prevents the most common round of utility questions.

Step 3: Submit the Interconnection Application

Interconnection is the formal request to connect your system to PSE’s grid. Most utilities use a tiered process. Smaller, simpler systems that meet standard requirements move through an expedited path, while larger or non-standard systems receive additional engineering review. Your application will be assigned a tier based on system size and the characteristics of your local circuit.

Submit the application before installing the system whenever the utility requires it. Installing first and applying later can lead to a rejected interconnection, forced equipment changes or removal of the array.

Typical timeline breakdown

Timelines vary with workload and system complexity, so build slack into your installation schedule.

Step 4: Install the System and Pass Inspection

Once the application is approved for construction, the system goes in. Key points to verify during installation:

• A lockable, visible AC disconnect near the meter, as required by most codes, so utility crews can isolate the system.
• Correct conductor sizing and overcurrent protection based on the inverter’s maximum output current.
• Grounding and bonding of the array frames, rails and equipment.
• Labeling of the PV source circuits, disconnects and the point of interconnection.
• Roof penetrations sealed properly if the array is roof-mounted.

The local inspector will verify these items. If you are not experienced with high-voltage DC wiring, hire a licensed electrician or a contractor who holds the appropriate state license.

Step 5: Get the Meter and Approval to Operate

Your home needs a meter that records energy flowing in both directions, so exports can be credited. PSE will either replace your existing meter or reprogram it, depending on its type. Do not energize the array until PSE has issued written permission to operate. Energizing early can violate your interconnection agreement and may delay your credits.

How Net Metering Credits Are Applied

Credits accrue on your monthly or billing-cycle statement. If your system exports more energy than you draw in a period, the surplus typically carries forward as a credit against future consumption. Credit treatment can differ by rate schedule and by the rules in effect when your application was filed, so ask PSE to explain exactly how exported energy is valued and how any remaining balance is handled at the end of the year.

Keep your own records. Compare your monthly production figures from the inverter with the export and import readings on your bill. Discrepancies are easier to resolve when you have dated data.

Common Mistakes

• Installing before approval. Starting work or energizing the array before PSE signs off is the fastest way to stall your project.
• Undersizing the disconnect or mislabeling it. Utility crews need a clearly marked, accessible switch.
• Submitting an unclear diagram. Vague or handwritten single-line diagrams generate repeated requests for information.
• Assuming the system works during outages. Grid-tied inverters shut down when the grid fails. Backup power requires a battery or a separately designed backup system.
• Ignoring rate changes. Review your rate schedule annually, since the value of exported energy and the structure of your bill can change.

Tips for a Smoother Process

• Ask your installer whether they have recently completed PSE interconnections and what tier they expect for your project.
• Photograph every stage of the installation, including wiring, labels and the meter base, for your records.
• Keep copies of all correspondence with the utility and note the names of staff you speak with.
• If you add panels later, reopen the interconnection process before the expansion is energized.
• Compare your monitoring data with your bill each month. Tools described in Home Solar Monitoring: Inverter Apps and Whole-Home Energy Monitors make this straightforward.

FAQ

Does Puget Sound Energy net metering apply to all solar systems?

Net metering generally applies to residential systems that meet PSE’s size and equipment requirements and that are interconnected at a PSE-served address. Larger or nonstandard systems may follow a different interconnection path. Check current PSE guidance before you design your system.

Do I need to apply to PSE before installing panels?

In most cases, yes. The interconnection application should be submitted and approved before the system is energized, and often before installation begins. Confirm the required sequence with PSE.

Will my solar system work during a power outage?

A standard grid-tied system shuts down during an outage to protect utility workers. To keep power on at home, you need a battery backup system designed for islanding, along with the appropriate transfer equipment.

What happens to excess energy at the end of the year?

Treatment of year-end surplus depends on the rate schedule and rules applicable to your account. Ask PSE to explain how any remaining credit balance is handled.

Do I need a bidirectional meter?

Typically yes. A meter that records energy flowing in both directions is needed so exports can be measured and credited. PSE determines the meter type for your account.

Can I add more panels later?

Yes, but expansions usually require a new or amended interconnection application. Adding capacity without notifying PSE can cause compliance problems.

Who should install the system?

A licensed electrical contractor familiar with grid-tied systems and local permitting is the safest choice. Many homeowners handle planning and paperwork themselves while leaving high-voltage wiring to professionals.

How do I check whether my credits are correct?

Compare your inverter’s production data and any whole-home monitor readings with the export and import figures on your bill. If something does not match, contact PSE with dated records.

Conclusion

Puget Sound Energy net metering rewards you for producing your own power, but only if the system is approved, installed to code and metered correctly. Work through eligibility, paperwork, interconnection and inspection in order, and avoid energizing the array before PSE gives written approval. Keep detailed records so you can verify credits and catch problems early.
