Your panels start cutting your bills the day they switch on. The export money is slower. Your first Clean Export Guarantee payment turns up as a credit on a normal electricity bill, and that only happens once your NC6 form has been processed, a smart meter is recording your export, and a full billing cycle has run. If you already have a smart meter, the first credit can appear on the very next bill after your form is processed. If you are waiting on a meter, the export clock does not start until it is in.
- Bill savings: immediate, from the day the panels are switched on
- Export payments: start once your NC6 form is processed and a smart meter is recording export
- Already have a smart meter? First credit usually lands on the next bill after the form clears
- Need a meter fitted? ESB Networks aims to install one within four months of a valid NC6. No export payment until then
- How it's paid: a credit on your electricity bill (some suppliers send a separate statement), at your supplier's CEG rate per kWh
Two Different Clocks: Savings vs Export Payment
The single most useful thing to understand is that solar pays you in two separate ways, and they start at different times. The self-consumption saving is the electricity you use straight from your own roof instead of buying it. It begins the moment the system is commissioned. There is no paperwork gate on it, and it is where most of the financial benefit comes from.
The export payment, the Clean Export Guarantee or CEG, is the bonus you get for the surplus your panels send to the grid. This is the part with a timeline. Before a supplier can pay you, three things have to be in place: ESB Networks has to know you are a micro-generator, your export has to be measured, and a bill has to run that includes that measured export. Miss any one of those and the credit does not appear.
The Export Payment Timeline, Step by Step
| Stage | What happens | Rough timing |
|---|---|---|
| 1. Install & switch-on | Panels commissioned. Bill savings begin immediately. No export payment yet. | Day 0 |
| 2. NC6 form submitted | Your installer notifies ESB Networks you've connected micro-generation. Usually part of the job. | Around install |
| 3. ESB Networks processes the NC6 | ESB Networks logs your connection and tells your electricity supplier. If you already have a smart meter, the supplier is notified automatically. | A few weeks |
| 4. Smart meter recording export | If you already have one, this is done. If not, ESB Networks aims to fit one within four months, and no export is paid until it's in. | 0 to 4 months |
| 5. First full billing cycle | Your supplier reads your exported units and applies the CEG credit on your next bill. | Next bill |
So the gating factor is almost always the smart meter. If yours is already installed and working, stage 4 is done and you are really just waiting for the NC6 to clear and the next bill to run. If you don't have a smart meter yet, that step is what stretches the timeline.
Even when everything is set up, export only appears on a bill once your supplier has pulled the export readings for that billing period. The first statement after your meter goes live can cover a part-period, so it may show less export income than you expect. It catches up on the following cycle.
How the Money Actually Reaches You
The CEG is not a cheque or a bank transfer. Under the Micro-generation Support Scheme, your electricity supplier pays you for every metered unit you export over your billing cycle, and that payment shows up as a credit on your electricity bill. Some suppliers itemise it on the bill itself, showing the billing period, the number of exported kWh, and the rate paid per unit. Others issue a separate microgeneration statement.
Because it is a bill credit, it offsets what you owe for the electricity you import. In a strong export month your bill can land at or near zero. The credit does not usually arrive as cash in hand unless your account goes into credit and you ask for a refund. How much each exported unit earns is a separate question, set by your supplier's CEG rate. Our solar export rate comparison tracks who pays what.
We match you with SEAI-registered installers in your county. They handle the NC6 form and the grant paperwork, and the smart meter exchange follows automatically. Free, no obligation.

You can't change the billing cycle, but you can stop the avoidable delays:
- Get the NC6 in promptly. Your installer normally submits it as part of the job. Confirm they have, because nothing downstream starts until ESB Networks has processed it.
- Sort the smart meter before, not after. If you don't already have one, you can request a smart meter from ESB Networks yourself using your MPRN rather than waiting to be scheduled. Doing it ahead of the install means the export clock can start as soon as the NC6 clears.
- Check your first bill. If a full cycle has passed since your meter went live and the NC6 was processed but no export credit shows, contact your supplier with your MPRN and your ESB Networks confirmation. Occasionally the export line needs to be switched on at their end.
One thing worth knowing for the tax side: the first €400 of micro-generation income each year is tax-free under a Revenue exemption that runs until the end of 2028. Most home systems sit comfortably under that, but our guide to tax on solar export income covers what happens above it.
What If My Home Can't Take a Smart Meter?
A small number of homes are technically unable to take a smart meter. Those households are not left out. They are paid on a "deemed export" estimate calculated by ESB Networks using a CRU formula, rather than on actual readings. It pays at your supplier's CEG rate, but it almost always undercounts what the panels really export. The full picture, including how the deemed figure is worked out, is on our smart meter and solar export guide.
Frequently Asked Questions
If you already have a smart meter, your first Clean Export Guarantee credit usually appears on the next electricity bill after your NC6 form has been processed by ESB Networks, a matter of weeks. If you need a smart meter fitted first, ESB Networks aims to install one within four months of a valid NC6, and no export is paid until it's in. Your bill savings, separate from export, start the day the panels are switched on.
It's paid as a credit on your electricity bill, not as a separate cash payment. Your supplier pays you their CEG rate for every metered unit you export over the billing cycle. Some suppliers itemise the export period, exported kWh and rate on the bill. Others send a separate microgeneration statement. If a strong export month pushes your account into credit, you can ask your supplier for a refund.
Export only appears once three things line up: your NC6 form is processed, a smart meter is recording your export, and a billing cycle has run that includes those readings. If your NC6 is still being processed, or a smart meter hasn't been installed yet, there's nothing for the supplier to pay against. The first statement after your meter goes live may also cover only part of a period, so it can look light before it catches up.
Usually not. If you have a smart meter and your NC6 or NC7 form has been processed by ESB Networks, your supplier is notified automatically and you don't need to apply separately. The exception is if a full billing cycle passes with no export credit showing. Then it's worth contacting your supplier with your MPRN and ESB Networks confirmation to make sure the export line is switched on at their end.
Yes. The electricity you use directly from your own panels cuts your bills from the day the system is switched on. There's no paperwork gate on that, and it's where most of the financial benefit comes from. The export payment for surplus you send to the grid is a separate bonus that follows once your NC6 form, smart meter and first billing cycle are all in place.
