How to Read Your Solar Export Meter in Ireland (Smart Meter Guide)

If you have solar panels in Ireland, knowing how to read your export meter is essential for tracking how much electricity you send to the grid and confirming your Clean Export Guarantee (CEG) payments are correct. At the time of writing, ESB Networks has installed over 2.4 million smart meters across Ireland as part of the National Smart Metering Programme (NSMP), with the rollout continuing until 2030.

This guide shows you exactly how to find your export reading on ESB Networks smart meters, what each display screen means, and what to do when your readings don't match the payments on your electricity bill.

Why Your Export Reading Matters

Your export meter reading determines how much you get paid under the Clean Export Guarantee scheme. Every kilowatt-hour (kWh) of electricity your solar panels export to the grid is recorded and should be credited on your electricity bill at your supplier's CEG rate (typically €0.18 to €0.24 per kWh at the time of writing).

The most common complaint from Irish solar owners is: "My meter shows I exported X kWh, but my supplier only paid me for Y." Usually this mismatch comes down to:

  • Not understanding which meter reading is the export figure
  • Reading the wrong register on the smart meter
  • Not knowing that CEG payments are often applied quarterly or as periodic bill credits
  • The smart meter not recording export properly (covered in our smart meter troubleshooting guide

Let's fix that by showing you exactly how to read your meter.

How to Read Your ESB Networks Smart Meter (Standard Model)

ESB Networks installs a standard digital smart meter for most Irish homes with solar panels. The meter has a single push button on the front that cycles through different display screens. Here is the step-by-step process:

Step 1: Find Your Meter

Your electricity meter is usually mounted on an exterior wall near your front door or side of the house. It will have a digital screen and a single button labelled with an arrow or circle symbol.

Step 2: Wake the Display (If Blank)

If the screen is blank, press the button once. The display will light up showing your main cumulative meter reading.

Step 3: Cycle Through the Displays

Each time you press the button, the meter cycles to the next screen. Here is what each screen shows:

Button Press What It Shows What It Means
No button (default) Cumulative kWh reading Your total electricity consumption from installation
Press 1 Date & time Current date and time on the meter
Press 2 Cumulative kWh (repeat) Same as default screen
Press 3 Night time reading (A+ T1) Electricity imported during night rate hours (11pm to 8am)
Press 4 Day time reading (A+ T2) Electricity imported during day rate hours (8am to 11pm, excluding peak)
Press 5 Peak time reading (A+ T3) Electricity imported during peak hours (5pm to 7pm)
Press 6 Test screen Meter display test (shows all segments)
Press 7 Export reading (A-) Total electricity exported to the grid

The Export Reading: Press 7

This is the number you need. When you press the button seven times, you will see:

  • "A-" displayed in the top right corner
  • A number followed by "kWh"

This is your cumulative export total since your solar system was connected. It only goes up, never down. Every time your solar panels export electricity to the grid, this number increases.

Example: If the display shows "A- 3,482 kWh", your system has exported a total of 3,482 kWh since installation.

How to Calculate Your Monthly Export

To work out how much you exported in a specific billing period, you need two readings:

Export at end of billing period - Export at start of billing period = kWh exported that month

Example:

  • Reading on 1 June: 3,120 kWh
  • Reading on 1 July: 3,482 kWh
  • Exported in June: 3,482 - 3,120 = 362 kWh

At a CEG rate of €0.20 per kWh, that is €72.40 in export credit for June.

Your electricity supplier receives these readings automatically from ESB Networks every 30 minutes via the secure smart meter communications network. You should not need to manually submit readings unless the meter is not connecting properly (see troubleshooting section below).

Different Meter Types in Ireland

While ESB Networks is rolling out a standard smart meter for most homes, there are a few variations you might encounter:

SMETS1 and SMETS2 Smart Meters

SMETS (Smart Metering Equipment Technical Specifications) refers to UK and EU smart meter standards. Ireland's National Smart Metering Programme uses meters that are broadly compatible with SMETS2 specifications.

The button-pressing sequence is the same as described above. The key difference is SMETS2 meters connect more reliably to the communications network and support more advanced features like half-hourly export data.

Day/Night Meters With Solar

If you have an older day/night meter (two separate mechanical dials), it cannot record export. ESB Networks will replace it with a smart meter as part of the NSMP rollout once your solar system is registered via the NC6 connection notification.

Until a smart meter is installed, suppliers may apply a deemed export estimate instead of metered export. This is typically calculated as a percentage of your system's estimated generation (often 30% to 40%), which is less accurate than metered export.

Analogue Meters Running Backwards

Some very old mechanical meters physically run backwards when solar panels export electricity. This was never the intended function and understates your true consumption. More importantly, you cannot claim CEG payments with an analogue meter because there is no separate export register.

If you still have an analogue meter with solar panels, request a smart meter upgrade immediately through your electricity supplier or ESB Networks.

When Export Readings Don't Match Payments

This is the most frustrating issue for solar owners. Here are the common causes and fixes:

Issue 1: You Are Not Enrolled for CEG

Symptom: Your export reading keeps increasing, but you see no credits on your electricity bill.

Cause: Clean Export Guarantee enrolment is not automatic with most suppliers. You must register your microgeneration system and confirm you have an inverter installed.

Fix: Log into your supplier's online account or call them with your MPRN (meter point reference number, found on your electricity bill). Ask: "Am I enrolled on a Clean Export Guarantee tariff?" If not, request enrolment immediately.

For detailed troubleshooting, see our guide on solar export payments.

Issue 2: CEG Is Applied as a Periodic Bill Credit

Symptom: You are enrolled for CEG, but you don't see it on every monthly bill.

Cause: Many suppliers apply export credits quarterly or on a periodic cycle rather than monthly. It appears in the "credits" or "adjustments" section of your bill, not as a separate cash payment to your bank account.

Fix: Look carefully at the credits section on your most recent bills for the past three months. The credit line might say "Export Credit", "Microgeneration Payment", or "CEG Payment".

Issue 3: Smart Meter Not Recording Export

Symptom: Your inverter app shows you are generating and exporting electricity, but your meter's A- reading stays at zero or increases much slower than expected.

Cause: The smart meter export register may not be properly configured, or the CT (current transformer) clamp is wired incorrectly.

Fix: This requires a professional. Contact your original installer or a Safe Electric registered electrician. Do NOT open the meter or touch any wiring yourself.

Issue 4: NC6 Connection Notification Missing

Symptom: Everything seems to work, but your supplier says they have no record of your microgeneration.

Cause: Your installer may not have submitted (or ESB Networks may not have processed) the NC6 connection notification that formally registers your solar system on the grid.

Fix: Ask your installer to confirm the NC6 was submitted and accepted. If it was not, they must submit it now. Without an approved NC6, your export is not formally recognised.

How to Submit Manual Readings to Your Supplier

In most cases, you do not need to manually submit export readings. ESB Networks sends them automatically to your supplier every 30 minutes via the smart meter communications network.

However, if your smart meter is not connecting properly to the network, your supplier may request manual readings. Here is how to do it:

  • Take your export reading (press button 7, note the A- number)
  • Log into your supplier's online account and look for "Submit Meter Reading"
  • Enter the export (A-) reading in the appropriate field
  • Enter the date you took the reading
  • Submit

Some suppliers have separate fields for import and export. Make sure you put the A- reading in the export field, not the import field.

Understanding Time-of-Use Tariffs and Export

If you are on a time-of-use (ToU) tariff, your import electricity is charged at different rates depending on when you use it:

  • Night rate (T1): 11pm to 8am (cheapest, €0.12 to €0.16/kWh)
  • Day rate (T2): 8am to 11pm excluding peak (mid-price, €0.30 to €0.35/kWh)
  • Peak rate (T3): 5pm to 7pm (most expensive, €0.40 to €0.50/kWh)

However, your export is typically paid at a single flat CEG rate regardless of when you export. At the time of writing, most suppliers pay €0.18 to €0.24 per kWh for all exported electricity.

This creates an important strategic opportunity: if you have a home battery, you can charge it with cheap night-rate electricity and discharge it during expensive peak hours, effectively arbitraging the price difference. For more detail, see our guide on battery storage savings.

Troubleshooting: My Meter Won't Show Export

If you press the button multiple times and never see an A- screen, your meter may not be configured for export. This can happen if:

  • The smart meter was installed before your solar system was connected
  • The NC6 connection notification was not processed by ESB Networks
  • The meter is an older model that predates the NSMP smart meter standard

What to do:

  • Contact ESB Networks on 1800 928 123 or 01 698 5005 with your MPRN
  • Explain you have a solar PV system and your meter is not showing an export register
  • They will check the NC6 status and confirm whether your meter supports export recording
  • If not, they will arrange a meter upgrade or reconfiguration

Final Thoughts

Reading your solar export meter correctly is the key to confirming your Clean Export Guarantee payments are accurate. The process is straightforward once you know which button to press: for ESB Networks smart meters, press the button seven times until you see A- in the top right corner. That cumulative kWh number is your total exported electricity since installation.

Most payment mismatches are administrative rather than technical. Check you are enrolled for CEG with your supplier, look for periodic bill credits rather than monthly cash payments, and confirm your NC6 connection notification was properly submitted. If your meter is not recording export at all, that requires a professional electrician or your installer to investigate.

For over 2.4 million Irish homes now on smart meters, the combination of accurate export tracking and Clean Export Guarantee payments makes solar panels more financially rewarding than ever.
