Solar changes how your electricity is measured. We explain the meter exchange after installation, who arranges each step, what affects timing, why your tariff may change, and how to read your first bill afterwards. When you install solar in NSW, your meter must record both the electricity you buy from the grid and the electricity you export. If you have an older meter that cannot do that, it is replaced with a smart meter; if you already have a smart meter, it may only need to be reconfigured. Your electricity retailer arranges the meter work through its metering coordinator, and the process is set in motion by the connection and compliance paperwork lodged around your installation.
Why the meter matters
Older accumulation meters simply count the total energy used. They cannot separate imports from exports, so they cannot credit you correctly for solar you send to the grid. Smart meters record imports and exports separately in short intervals, which is what allows retailers to pay a feed-in tariff and to apply time-of-use pricing. Without the right meter, the solar system may work perfectly and your bill will still not reflect it.
The process, step by step
- Network approval before installation: the installer applies to your local electricity network for permission to connect, and the approval sets conditions such as any export limit.
- Installation and compliance: the system is installed by SAA-accredited installers and licensed electricians, tested, and the required electrical compliance paperwork is completed and lodged.
- Retailer arranges the meter work: your retailer's metering coordinator either sends a technician to replace the meter or reconfigures an existing smart meter remotely.
- System switched on for export: depending on the network's rules and your existing meter, the system may need to stay off or export-limited until the meter work is done. We tell you which applies to your home.
- Billing updated: the retailer applies your feed-in tariff and any tariff changes, and your next bill shows imports and exports separately.

How long it takes
Timing varies. A remote reconfiguration of an existing smart meter can be quick, while a physical replacement depends on the metering coordinator's schedule and on getting safe access to your meter. The most common causes of delay are avoidable:
- a locked gate, meter box or garage, or a dog in the yard on the day;
- a meter board with asbestos backing or old wiring that technicians cannot safely work on;
- a change of retailer part-way through the process, which can restart the request;
- incorrect or missing contact details on the retailer's account.
If your meter board needs work, a Switchboard Upgrade is listed in our energy market from $1,490 for a standard residential board. If you would like us to follow up the meter exchange with your retailer and metering coordinator for you, our Smart Meter & Metering Coordination service is $199 per property. Both prices are indicative and confirmed after a site assessment.
Adding a battery to existing solar
If you already export solar through a smart meter, adding a battery often needs no meter change at all, because the meter already measures imports and exports separately. The network still needs an application for the battery, and the inverter settings, including any export limit, are set to match the approval. Where a home still has an older meter from an early solar installation, or the retailer's records do not match the equipment on site, the meter may need attention at the same time. We look at the meter during the site assessment, so any metering work is planned from the start rather than discovered after installation.
Why your tariff may change
A new or reconfigured meter can change more than the hardware. In NSW, a meter change can lead to a different network tariff behind your plan, most commonly time-of-use pricing with peak, shoulder and off-peak rates, and your retailer may pass that change through to you. Your plan will also need a feed-in tariff for exports. Things to check with your retailer:
- which tariff structure applies after the meter change, and the rates for each time band;
- the feed-in rate and whether it has conditions attached;
- whether any existing discounts or benefit periods continue on the new setup;
- that a controlled load circuit, such as off-peak hot water, is still connected and billed correctly.
Feed-in tariffs in NSW are commonly a few cents per kWh, far below the 30-45 c/kWh commonly paid for grid electricity, so the rates on your usage matter more than a slightly higher feed-in rate. After your first full billing period with export data, the feed-in tariff comparison helps you judge whether your plan still suits you.
Reading your first bill after solar or a battery
The first bill after the change often looks unfamiliar. Here is what to expect and what to check:
- Split billing period: part of the period may be on the old meter and part on the new one, sometimes with an estimated read. Estimated reads are usually marked on the bill.
- Usage by time band: on time-of-use pricing, imports are shown separately for peak, shoulder and off-peak periods.
- Solar feed-in credit: exported kWh multiplied by your feed-in rate, shown as a credit.
- Daily supply charge: a fixed charge for every day of the period, which solar does not change.
- Meter number: it should match the new meter on your wall.
With a battery, expect lower evening imports and fewer exports, because surplus solar is stored rather than sent to the grid. If exports show as zero while your system is clearly producing, contact your retailer, as the meter may not be configured correctly yet. Our FAQs cover other common questions after installation.
Next steps
When you request a quote, include a photo of your meter box and your latest bill. We will check your meter and switchboard during the site assessment, explain what the meter change will involve for your home, and handle the network application so the process runs as smoothly as possible.
Frequently asked questions
Do I have to pay for the new meter?
It depends on your retailer. Some include the meter exchange at no separate charge, while others apply a fee or recover metering costs through your daily charges. Ask your retailer before installation so there are no surprises on the first bill. Any fee from the retailer is separate from our Smart Meter and Metering Coordination service, which covers following up the process on your behalf.
Why doesn't my monitoring app match my bill exactly?
The app measures at the inverter or through current sensors in your switchboard, while the meter is the billing reference, so small differences are normal. Timing of readings, sensor placement and estimated meter reads all contribute. A persistent large gap, such as exports on the bill far below what the app shows, is worth raising with your retailer, because the meter configuration or tariff setup may be wrong.
Should I switch retailers while I am waiting for the meter change?
It is usually better to wait. Switching part-way through can pass the request to a new retailer and metering coordinator, which may restart the process and delay the start of your feed-in credits. Once the meter work is complete and a bill shows your exports correctly, you can compare plans with real data and switch with confidence if a better offer suits your usage.
